Use of secretin in the roentgenologic and biochemical diagnosis of duodenal gastrinoma.

The use of secretin in the biochemical and roentgenologic diagnoses of a duodenal gastrinoma has been described. Preoperatively, the secretin test indicated that a gastrinoma and not a retained antrum was the cause of hypergastrinemia in a patient who had previously undergone Billroth II gastrectomy. Intravenous infusion of secretin during selective angiography resulted in greatly enhanced visualization of the tumor which allowed it to be localized to the duodenal stump. Several months postoperatively, the secretin test result had become negative, which presumably suggested that the tumor had been excised completely. Our experience has revealed that intravenous secretin might improve the diagnostic usefulness of selective angiography.

Roentgenologic features of pulmonary blastomycosis.

In 35 cases of pulmonary blastomycosis, the roentgenologic features were as follows: consolidation 26%, mass 31%, intermediate-sized nodules 6%, miliary pattern 11%, solitary cavity 9%, fibrotic and cavitary changes 6%, interstitial pattern 6%, diffuse alveolar involvement 3%, and mixed alveolar and interstitial infiltrate 3%. All symptomatic cases of consolidation were acute (symptoms for less than 1 month), and most were in young patients (mean age, 34 years). Consolidation constituted 58% of the acute cases in this series. Two of the nine cases of consolidation were asymptomatic epidemic cases detected by screening. A pulmonary mass was the most common initial manifestation in this series; it tended to occur in patients with chronic symptoms (more than 1 month). The mass was considered suggestive enough of bronchogenic carcinoma to necessitate resection in 55% of cases. The military form of pulmonary blastomycosis occurred in older patients with disseminated disease. Fibrotic and cavitary disease was chronic in nature. The presence of intermediate-sized nodules elsewhere in the lung proved to be a helpful diagnostic finding in several patients with consolidation, mass, or cavitary disease. Hilar adenopathy, postinfectious calcification, chest wall invasion, and pleural effusion occurred infrequently or not at all in this series.

[The importance of scintimetry in the differential diagnosis of roentgenological areas of increased "translucence" in the skeleton of children (author's transl)].

A random selection of lesions representing osteolytic bone processes was evaluated with the "region-of-interest" technique in order to determine whether scintimetry can be helpful in the differential diagnosis of such processes in children. Bone tumours with structural densification, as well as osteomyelitides, were reviewed for comparative purposes. It was found that scintigraphy of the skeleton, while supplying additional and clinically quite interesting information, does not make any substantial contribution to the differential diagnostic clarification of roentgenological translucence in the skeleton of children.

Tetracycline ulcers of the oesophagus, Endoscopy, histology and roentgenology in two cases, and review of the literature.

Two cases of tetracycline ulcers of the oesophagus are reported and compared with thirteen other cases from the literature. In most cases, the patients had taken their capsules with little or no fluid just before going to bed. Some hours later they developed retrosternal pain that was intensified by swallowing. Endoscopy showed sharply demarcated greyish-white areas of mucosal damage which represented layers of stratified squamous cells, separated by oedema, and a dense neutrophilic infiltration of the lamina propria and the muscularis mucosa. Roentgenology was unsuitable to detect the lesions. They healed without complications within one to six weeks. Prolonged retention of the capsules in the oesophagus is thought to cause the mucosal damage. Patients on oral tetracycline or doxycyline treatment should therefore be instructed to take their capsules with a meal or with copious water and not just before going to bed.

[Chip fracture of the lateral tibial condyle--a roentgenologic sign of anterior cruciate ligament injury].

A case report serves as basis for describing the importance of the so-called chip fracture as the first roentgenological pointer to a rupture of the anterior cruciate ligament in a handball player. The paper discusses the biomechanical changes resulting from an ACL rupture and underlines the importance of early arthroscopic diagnosis or of arthroscopic surgery for regaining knee stability and for preventing secondary subsequent damage.

[Patient analysis of roentgenologically diagnosable skeletal manifestations of hemoblastoses].

A patient analyse about 672 adults and 164 children at the medical hospital of Leipzig University between 1978 and 1990 will be introduced here. The results will be discussed under following aspects: I. diagnostical criterions to limit the number of diseases, which may be the cause of roentgenological diagnosed bone lesions: 1. morbidity peak of the most common entities causing lesions of the skeleton, 2. how frequently one of these diseases causes bone alterations, 3. location and distribution of the skeleton manifestations, 4. character of these lesions. II. recommendations for the procedure enables to diagnose bone lesions by recognized haemoblastoses. III. criterions to evaluate by control-X-ray's of the skeleton changes the therapeutical effects in comparison with the dynamic of the disease causing the bone lesions. It will be accentuate the importance to consider more-frequently haemoblastoses in the differential diagnosis of bone lesions.

Complex motion tomography of the sacroiliac joint. An anatomical and roentgenological study.

To find a better method for diagnosing sacroiliac (SI) joint disease, an anatomical approach was combined with conventional roentgenology, complex motion tomography and computed tomography. Complex motion tomography is suggested as the method of choice in the investigation of the SI-joint. Because of its complex (sinusoidal) form, the dorsal portion of the joint has to be tomographed in frontal projection and the middle and ventral portions in oblique projection. In 56 patients, referred for probable ankylosing spondylitis, 72 SI joints were investigated. Based on plain radiography six and on frontal tomography five SI joints were diagnosed as normal. However, based on oblique tomography 31 joints were diagnosed as normal.

[Roentgenological demonstration of pathological changes of the mucosa of the small intestine].

Use of a special high molecular guar preparation in small bowel contrast studies results in a roentgenological detection of the villous architecture of the small intestine. A diffuse villous atrophy results in a loss of the normal granular pattern. Segmental loss of granular mucosal texture is found in chronic radiogenic enteritis. In active Crohn's disease a coarser diffusely distributed granular appearance of the mucous surface occurs in addition to the segmental inflammatory changes. A coarse granular mucosal pattern with only segmental involvement is seen in mild malabsorption syndrome in the upper jejunum. Radiological signs for an intestinal protein loss syndrome is a coarse and weakly contrasted granular mucosal pattern in the lower ileum with moderate thickening of the jejunal folds and increased liquid content of the bowel.

[The possibility of side effects during the application of roentgenologic contrast media by the method of the biphasic bolus/perfusor injection and the monophasic bolus injection (author's transl)].

In spite to lower the dose dependent side effects by the application of roentgenologic contrast media in the computed tomography a system of a biphasic injection per bolus and perfusor was installed and compared with that of the monophasic bolus injection. Special rules on the installation of the perfusor at CT should be observed.

Roentgenologic aspects of haematuria.

In the roentgenologic investigation of haematuria, urography is the main diagnostic tool, other examinations being only of supplementary value. The main importance of other roentgen examinations is the possibility of excluding certain types of suspected disease as the cause of haematuria, and to demonstrate certain vascular malformations in the kidneys with renal angiography. Urography and cystoscopy should be performed in all patients with haematuria, and the possibility of pathologic conditions in both upper and lower urinary tract must be kept in mind. A large number of overlooked calculi and the finding of unsuspected malignant renal tumors in cases where the urography was performed on an emergency basis, underlines the important fact that "emergency" in these cases only indicates that the patient is an acute distress, not that the examination should be hasty and incomplete, or if so, should be supplemented by a repeat examination under normal conditions.

A computer program for the localization of small areas in roentgenological images.

A method and associated algorithm are presented which allow a simple and accurate determination to be made of the location of small symmetric areas presented in roentgenological images. The method utilizes an operator to visually spot object positions but eliminates the need for critical positoning accuracy on the operator's part. The rapidity of measurement allows results to be evaluated on-line. Parameters associated with the algorithm have been analyzed, and methods to facilitate an optimum choice for any particular experimental setup are presented.

Unstable thoracolumbar fractures. A study by CT and conventional roentgenology of the reduction effect of Harrington instrumentation.

Fourteen patients with unstable thoracolumbar fractures were examined with conventional roentgenologic technique and CT before and after operation with Harrington instrumentation. CT was superior in evaluating posterior elements, bone fragments in the spinal canal, and degree of narrowing of the spinal canal. Harrington rods restored the general spinal alignment. However, even after surgery, the midsagittal diameter, as well as the cross-sectional area of the spinal canal were still diminished by 26%. The reduction of the spinal canal improved significantly by early surgical intervention. Open reduction and stabilization with Harrington rods and fusion within three days after injury is recommended.

Roentgenological detection of casting defects in cobalt-chromium alloy frameworks.

A method for non-destructive X-ray investigation of casting defects in cobalt-chromium prosthetic frameworks has been developed and tested. The attenuation properties of a cobalt-chromium alloy were studied. A dental X-ray machine with a tube voltage working at 70 kVp and a focus-film distance of 45-50 cm on dental ultraspeed film made it possible to detect defects representing 10% or less of the thickness of cobalt-chromium details with dimensions between 0.6 and 3.0 mm. The frequency and site of internal defects in sixty-six frameworks were investigated. Of the sixty-six frameworks only two were without roentgenologically visible defects. In the other sixty-four frameworks 294 pores or cracks were recorded. The defects were mostly situated in the saddles. Porosities occurred in 53% of the saddlebar regions. The results confirmed the need for a non-destructive routine test of prosthetic frameworks.

The roentgenologic diagnosis of chronic bronchitis: a reassessment with emphasis on parahilar bronchi seen end-on.

In an attempt to reassess the accuracy of the roentgenologic diagnosis of chronic bronchitis, we have studied the chest radiographs of approximately 300 men comprising roughly equal numbers of normal subjects and patients with chronic obstructive pulmonary disease (COPD). Emphasis has been placed on the thickness of bronchial walls visualized end-on in the parahilar zones, identified in roughly 80% of both groups. Step-wise discriminant analysis of six variables showed that the median estimate of bronchial wall thickness was of some value in discrimination.

The value of roentgenologic screening in lung cancer.

A series of 446 patients with lung cancer were followed for 5 yr or until death to find out whether the mode of detection of the cancer affected their prognosis. The patients were divided into 2 groups. Group A: patients whose cancer was diagnosed in mass radiography, or some other health examination, or in an examination for another disease. Group B: patients who had consulted a doctor on account of their symptoms. Of the patients in Group A, 50% were alive 1 yr after diagnosis and 5% after 5 yr. The corresponding figures in Group B were 24% and 4%. In 127 patients, an abnormal shadow could already be seen in roentgenograms taken 6 months or more before diagnosis. These patients survived longer than the others, 9% being alive 5 yr after diagnosis. The results do not suggest that roentgenologic screening improves the prognosis for lung cancer.

Roentgenologic appearance of fibromuscular dysplasia.

Clinical and roentgenologic findings in 100 hypertensive patients with fibromuscular disease of the renal arteries are presented and compared with the experiences obtained from previously reported large series. Frequency of bilateral disease and abnormal findings at urography, involvement of segmental arteries and occurrence of extrarenal manifestations are reported. A striking female preponderance is noted, and there is evidence that the disease inflicts middle-aged rather than young women.

Roentgenologic evaluation of a new prosthetic sphincter for the treatment of urinary incontinence.

A new prosthetic device for the treatment of urinary incontinence, caused by a variety of etiologies, has been used 8 times at the University of Michigan Medical Center. Since the entire device is filled with contrast medium, the radiologist plays a major role in its evaluation. A brief description of the implantable urinary sphincter and its normal and abnormal roentgenographic appearances are presented and discussed. Roentgenologic findings which could lead to early clinical detection of mechanical failure are illustrated.
