Shoulder arthrography with sodium meglumine metrizoate and iopamidol.

The purpose of this study was to analyze arthrographic imaging of the structures of the shoulder joint when using either sodium meglumine metrizoate or iopamidol as a contrast medium. Two hundred and ten patients underwent single-contrast shoulder arthrography. In patients with a full-thickness tear of the rotator cuff, both contrast agents reliably revealed this lesion. However, in patients with a full-thickness rotator cuff tear, the biceps tendon could be demonstrated more readily with iopamidol, which is a non-ionic contrast medium.

A comparative study of the patello-femoral joint on axial roentgenogram, axial arthrogram, and computed tomography following arthrography.

After arthrography 71 young patients with pain in the knee had a computed tomography (CT) examination. The form of the patella is classified according to the method of Wiberg [12] and on CT 50% of them do not correspond to the type described on the axial roentgenogram. The position of the patella can be examined on CT with a relaxed knee in 15 degrees of flexion. The patellar cartilage is easier to assess on CT: congruity, regularity, imbibition of contrast material and thickness are studied.

Joint fluoroscopy before arthrography: detection and evaluation of loose bodies.

Fluoroscopy before injection of contrast medium increased the usefulness and accuracy of arthrography in 14 of 22 patients with possible intra-articular loose bodies. Although loose bodies wedged between articular surfaces deep within the joint were immobile, a typical tumbling motion on fluoroscopy reliably identified most free-floating loose bodies. Fluoroscopy sometimes revealed abnormalities more clearly than the plain radiographs or arthrograms.

Frequency and topography of lesions of the femoro-tibial cartilage at spiral CT arthrography of the knee: a study in patients with normal knee radiographs and without history of trauma.

OBJECTIVE: To determine the frequency and topography of cartilage lesions involving the femoro-tibial joints in patients with normal knee radiographs and without a remembered history of trauma. DESIGN AND PATIENTS: A radiologist retrospectively reviewed the dual-detector spiral CT knee arthrograms performed in 209 consecutive patients (mean age 37.6 years) with normal knee radiographs. Images were analyzed for the presence, grade (Noyes classification system) and location of cartilage lesions, the location being designated by dividing each articular surface into a grid of 16 parts. RESULTS: Fifty-three percent of knees had cartilage lesions of grade 2A or higher that involved articular surfaces to a variable extent: lateral tibial plateau (31%), medial femoral condyle (27%), medial tibial plateau (14%) and lateral femoral condyle (5%). Areas of the posterior half of the lateral tibial plateau and of the inner half of the medial femoral condyle were statistically more frequently involved than their counterparts (P<0.0001). The bare area of the medial tibial plateau, but not that of the lateral tibial plateau, was more frequently involved than the corresponding meniscus-covered area (P<0.0001). CONCLUSION: Cartilage lesions of grade 2A or higher, detected at spiral CT arthrography in 53% of the knees, predominantly involved the posterior half of the lateral tibial plateau, the inner half of the medial femoral condyle and the bare area of the medial tibial plateau.

Diagnosis of superior labral lesions: comparison of noncontrast MRI with indirect MR arthrography in unexercised shoulders.

OBJECTIVE: To prospectively compare the accuracy of noncontrast magnetic resonance imaging (MRI) with indirect MR arthrography (I-MRa) of unexercised shoulders for diagnosis of superior glenoid labral lesions. MATERIALS AND METHODS: Institutional Review Board approval and patient informed consent were obtained for this prospective study. Superior labral findings on shoulder MRI and unexercised I-MRa studies of 104 patients were correlated with findings at arthroscopic shoulder surgery. Two musculoskeletal radiologists independently reviewed the two sets of MR images while blinded to arthroscopic results. For each radiologist, the McNemar test was used to detect statistically significant differences between techniques. RESULTS: The superior labrum was intact in 24 and abnormal in 80 subjects. For detection of superior labral lesions by each radiologist, I-MRa was more sensitive (84-91%) than MRI (66-85%), with statistically significant improvement in sensitivity for one reader (p = 0.003). However, I-MRa was less specific (58-71%) than MRI (75-83%). Overall, accuracy was slightly improved on I-MRa (78-86%) compared with MRI (70-83%), but this difference was not statistically significant for either reader. CONCLUSION: Compared with noncontrast MRI, I-MRa was more sensitive for diagnosis of superior glenoid labral lesions. However, the diagnostic value of I-MRa in shoulders remaining at rest is potentially limited by decreased specificity of the technique.

Indirect wrist MR arthrography: the effects of passive motion versus active exercise.

PURPOSE: In the wrist, to determine whether passive motion or active exercise yields a better indirect MR arthrographic effect following intravenous gadolinium administration. DESIGN AND PATIENTS: Twenty-six consecutive patients were studied by indirect wrist MR arthrography. In half active exercise and in half passive motion was performed. Four regions of interest were studied including the distal radioulnar joint, the radiocarpal joint, the midcarpal joint, and the triangular fibrocartilage. Ranges and means of signal intensity were calculated. Surgical follow-up was performed in 22 patients. RESULTS: The joint fluid intensity was greatest in the distal radioulnar joint. Fluid signal intensity was greater and more consistent in the passive motion group although the results did not achieve statistical significance. Imaging accuracy appeared similar in the two groups and was excellent for the triangular fibrocartilage (100%) and scapholunate ligaments (96%). CONCLUSION: Active exercise and passive motion yield similar degrees of wrist arthrographic effect, but the effect of passive motion is somewhat more consistent. Preliminary data show good accuracy for internal derangements.

Spiral CT arthrography of the knee: technique and value in the assessment of internal derangement of the knee.

Computed tomography imaging has achieved excellent multiplanar capability and submillimeter spatial resolution due to the development of the spiral acquisition mode and multidetector row technology. Multidetector spiral CT arthrography (CTA) yields valuable information for the assessment of internal derangement of the joints. This article focuses on the value of spiral CTA of the knee in the assessment of the meniscus, anterior cruciate ligament, and hyaline cartilage lesions. Advantages and disadvantages of spiral CTA with respect to MR imaging are presented.

The significance of subacromial arthrography to verify partial bursal-side rotator cuff ruptures.

BACKGROUND: The purpose of this study was to verify a partial bursa-side rupture of the rotator cuff (RC) using different imaging techniques with special emphasis on the validity of a specific method of subacromial arthrography (SAA). METHODS: Patients (n=92, mean age 53.8 years) with a subacromial impingement syndrome underwent sonography, magnetic resonance imaging (MRI), and SAA. All diagnostic results were checked by subsequent arthroscopic surgery. RESULTS: Of 31 surgically verified ruptures, 17 showed a partial rupture located towards the bursa. These had been detected by MRI and ultrasound with a sensitivity of 64% and 41%, respectively, while SAA as a diagnostic tool yielded a sensitivity of 82%. In 14 cases of complete RC ruptures, all imaging techniques had a similar sensitivity of 86-93%. CONCLUSION: It appears that SAA is an adequate and valid diagnostic tool for the detection of partial bursa-sided RC ruptures. Ultrasound and MRI showed a comparably lower sensitivity. It is therefore concluded that SAA has clear advantages in the diagnosis of this defect with the consequence that open surgical techniques can be avoided.

The value of arthrography and arthroscopy in association with a sports injuries clinic: a prospective and comparative study of 182 patients.

A series of 182 patients who presented through an athletes clinic wih internal derangements of the knee have been studied prospectively with regard to clinical, arthrographic and arthroscopic findings. The diagnostic inaccuracies of arthography and arthroscopy are detailed. In this group of patients arthroscopy achieved the greatest overall accuracy, and is recommended as the inhitial investigation. Arthrography is advocated in cases where a suspected tear of the posterior horn of the medial meniscus has not been revealed by arthroscopy.

Inferior joint space arthrography and characteristics of condylar paths in internal derangements of the TMJ.

Inferior joint space arthrography and measurements of the condylar path provide scientific documentation of derangement of the TMJ disc and condyle. These derangements are described as an anterior displacement of the disk associated with posterior-superior displacement of the condyle when the teeth are closed into the intercuspal position. Clinical studies demonstrate that approximately 70% of a TMJ patient population present with some type or stage of these derangements. These observations have far-reaching implications regarding contemporary dental curriculum, particularly concerning exegesis of the MPD syndrome theory and concepts of dysfunctional dental occlusion.

Transcutaneous electric nerve stimulation (TENS) during distension shoulder arthrography: a controlled trial.

Transcutaneous electric nerve stimulation (TENS) is a safe and simple form of analgesia but is little used as an adjunct to local anaesthesia during routine procedures. This trial investigates the use of TENS in the radiology department using distension shoulder arthrography for 'frozen shoulder', a moderately painful procedure, as a model. Sixty patients with a clinical diagnosis of 'frozen shoulder' were randomised to receive high-intensity TENS, low-intensity TENS or to act as controls. A standard procedure was then performed. Following the procedure patients completed a visual analogue pain scale. Mean recorded pain levels were lower in the TENS groups with a 50% difference between the high-intensity group and a 38% difference between the low-intensity group as compared to control (difference statistically significant P < 0.01 and P < 0.05, respectively). TENS was well tolerated by patients. The 50% reduction in mean pain levels supports the use of TENS for routine painful procedures.

Prognostic value of magnetic resonance arthrography for Czerny stage II and III acetabular labral tears.

PURPOSE: To assess the intraobserver reliability and prognostic value of magnetic resonance arthrography (MRA) on the basis of postoperative outcome measures following arthroscopic acetabular labral debridement (partial limbectomy). METHODS: Between January 1999 and November 2000, 24 patients (13 females, 11 males) with an average age of 37.1 years (range, 21 to 56 years) underwent hip arthroscopy for the treatment of presumed acetabular labral tears. All patients underwent preoperative MRA and/or magnetic resonance imaging (MRI); images were evaluated by a single musculoskeletal radiologist on 2 independent occasions. Hip arthroscopy was performed on all patients. Outcomes were assessed by means of the Modified Harris Hip Score (MHHS) and the Short Form-36 (SF-36) questionnaires, which were completed by patients an average of 24.1 months (range, 12 to 55 months) postoperatively. The accuracy of the initial read, as well as the prognostic value of the Czerny MRA classification system for stage II (intrasubstance tears) and stage III (complete avulsions) acetabular labral tears, was assessed. RESULTS: Twenty-two of 23 tears (96%) were detected on the initial read. On the basis of intraoperative findings, 1 false-positive MRA, 1 false-negative MRA, and 1 incident of MRA overstaging were reported. On repeat interpretation, 23 of 23 (100%) tears were identified, and intraobserver reliability for recording the presence of a tear was excellent (kappa coefficient = 0.96). No difference was noted in outcomes between patients with or without arthroscopic evidence of chondromalacia (all P > .29), or between patients older or younger than 30 years (all P > .34). Likewise, no difference in outcome was seen between 15 patients with Czerny stage II tears revealed on MRA versus 9 patients with Czerny stage III tears (all P > .79). CONCLUSIONS: MRA is sensitive and accurate for the detection of acetabular labral tears, with excellent intraobserver reliability. Arthroscopic partial limbectomy is successful in two thirds of patients. Patients with Czerny stage II and III tears do not appear to have significantly different outcomes following arthroscopic labral debridement. LEVEL OF EVIDENCE: Level IV, prognostic case series.

Essentials of shoulder MR arthrography: a practical guide for the general radiologist.

Lesions of the glenoid labrum and ligamentous structures commonly occur secondary to shoulder trauma and are a frequent cause of shoulder joint instability. Numerous eponyms, acronyms and subclassifications are used to describe the often confusing array of bony and labro-ligamentous abnormalities of the shoulder. This aim of this review is to illustrate the relevant features of these lesions and to provide a systematic and practical approach to imaging of the shoulder using MR arthrography.

Normal anatomy and common labral lesions at MR arthrography of the shoulder.

MR arthrography of the shoulder is the most accurate imaging modality in demonstrating abnormalities of the glenoid labrum and associated structures. Tears of the labrum, the capsule or the gleno-humeral ligaments can lead to pain, catching, popping or instability. The anatomy of this region is complex. We present the normal anatomy of the glenoid labrum, biceps anchor and gleno-humeral ligaments together with their normal variants and then describe common labral-ligamentous pathologies.

Double contrast knee arthrography. Some new points of technique including the use of Dimer X.

A short review of the development of techniques in knee arthrography is given, together with a full account of the author's technique, including the use of a specially designed pad and a frame to facilitate radiography and a new method to demonstrate the cruciate ligaments. Side effects in a group of patients examined using Dimer X as the positive contrast medium are compared with those in a group of patients who were examined using Urografin 60%. Comparason of the radiological advantages of Dimer X examinations with Urografin 60% examinations has been made. A possible method to distinguish normal from damaged or degenerate tissues is suggested. The author concludes that Dimer X is the positive contrast medium of choice at the present time.

Investigation of shoulder disability by arthrography.

Fifty patients with pain and limitation of movement at the shoulder joint were investigated by arthrography. Normal findings using a double contrast technique are described. The main arthrographic patterns encountered were found in complete and incomplete tears of the rotator cuff, and capsulitis. Abnormalities of the bicipital tendon sheath were non-filling and leakage of contrast medium from the sheath. Extravasation of contrast medium from the bicipital tendon sheath and subscapularis bursa was considered to be due to over-distension of a joint with a reduced capacity. The accuracy of the procedure and the reasons for false negative arthrograms and surgical exploration are discussed.
