[Magnetic resonance imaging in the diagnosis of soft cervical disk hernia. Evaluation report on 20 cases previously examined by x-ray computed tomography].

Twenty successive patients were examined using CT scanning followed by M.R.I. Thirteen were subsequently operated upon. The results are reported in detail, specifying which signals were used to make the diagnosis of cervical disc prolapse. Short sequences were used for degeneration in the herniated disc, disc protrusion into the spinal canal and compression of the spinal cord. Long sequences were used for indentations or blocks in the cerebro-spinal fluid column at the level of the disc prolapse. Ordinary disc degenerations and associated stenoses are also shown. The reliability of the method was established by comparison with radiographs and surgical findings which were shown to be positive in all the 13 cases treated surgically. The report discusses the difficulties and current limitations of magnetic resonance imaging such as the scarcity of machines, the supine position, the length of the examination, the mediocre quality of horizontal axial sections and difficulties in transmitting magnetic resonance information. There is expected to be rapid and decisive progress with the use of rapid imaging, the preferential choice of sequences, the use of scout views and closer collaboration between radiologist and clinician. A final section is devoted to a discussion of the relative merits of CT scanning and M.R.I. The latter has the advantage of providing total three-dimensional information, particularly in the sagittal plane with a better appreciation of the relationship between container and contents and a method which is strictly non-invasive with the use neither of contrast medium nor X-rays. The authors conclude that M.R.I. provides a positive contribution to the diagnosis of cervical disc protrusions and that this technique can, from now onwards, be considered the examination of choice.

[Study of a painful total hip prosthesis].

The authors propose a simple routine survey to be performed in the case of a painful total hip prosthesis which is generally able to define the diagnosis and the prognosis. X-ray films are more valuable by their repetition than by their simple analysis. Certain minor signs can help predict or detect loosening of the prosthesis or other complications, but in the great majority of cases, radiology alone is not sufficient to make the diagnosis, as the films are only able to show clear spaces around the prosthesis, without being able to definitely confirm the aetiopathogenic significance of this sign. In these cases, when the decision has not been taken to re-operate, more sophisticated investigations are required (scintigraphy, dynamic tests, arthrography), although they must be used with caution as very often the clinical findings will have the last word.

[Unusual indications for scanning in osteoarticular pathology].

The authors take stock of current applications of the scanner in osteoarticular pathology. At first (1978-1983 approximately), only the vertebral column could be studied by this technique. Now, almost all the osteoarticular system is susceptible to study. Established examples are: study of the sacrum, of the traumatized acetabulum, of the femoropatellar apparatus, and measurement of torsion in the lower limbs. New applications are: study of the back of the foot, of the patellar cartilage, of the glenoid cavity, of the bones and soft parts of the hand, three-dimensional reconstructions, scanning radiology. The authors index and analyse these new techniques.

[X-ray computed tomographic exploration of cervico-brachial neuralgia. Value of the intravenous injection of contrast media].

Cervicobrachial neuralgias can now be easily evaluated by computerized tomography of the cervical spine due to recent technical progress (improved resolution, ultra-thin cuts, precise localization by computed radiography), and especially the use of intravenous contrast material, thus avoiding intrathecal metrizamide. The authors describe normal findings obtained by this method as well as disk herniations and disco-uncarthrosis. On the basis of this initial study of 35 patients (7 disk herniations and 16 disco-uncarthrosis), this method could be employed following routine studies as the first preoperative examination for cervicobrachial neuralgia. Thus, the indications for cervical myelography would decrease, limiting the use of a more invasive procedure and patient discomfort.

[Computed x-ray tomographic evaluation of cervico-brachial neuralgia with intravenous injection of contrast media].

Investigation of the cervical epidural space by a CT scan is facilitated by its filling following intravenous injection of a contrast medium. The spinal ganglia and nerve root sheaths are visualized as negative images in the intervertebral foramen. A herniated disc is seen as a focal protrusion of the anterior epidural space presenting a clearer center (60 to 80 HU) than at the periphery (100 to 120 HU). Disco- osteophytic protrusion is seen as an arthritic hypertrophy of the uncus and a more widespread overlapping of the disc, often with a posterior body osteophytosis. The spinal cord and subarachnoid space are also visualized more clearly than when injections are not given. This technique is proposed as the initial examination after standard films, for preoperative investigation of a resistant cervicobrachial neuralgia .

[Stenosis of the lumbar canal: nosologic and semeiologic study. 163 operated cases].

The authors report a retrospective study of 163 cases of degenerative or constitutional stenosis of the lumbar canal. In this series, the most frequent cause was osteoarthrosis and constitutional stenoses were relatively rare. The authors note that this is often a difficult aetiological distinction to make, especially in elderly patients and the anatomical deformities caused by osteoarthrosis lead to stenosis of the canal similar to that seen in constitutional malformations. Sensori-motor claudication is inconstant and was only found in one third of the cases in this series. More often, the lumbar stenosis presents as nerve root pain. It can be distinguished from root disease of disc origin by the frequent absence of Lasegue's sign and of spinal stiffness. When a herniated disc is associated with a stenosis, the clinical picture is altered and can then resemble that of disc sciatica. The diagnosis of stenosis depends on the radiological examination. This series confirms the diagnostic value of the abnormalities seen on standard X-rays, but the severity and the extent of the stenosis can only be assessed by performing tomography, water-soluble contrast myelography and C.T. scan. The authors discuss the limitations and degree of reliability of each of these investigations. The extent of the surgical decompression depends on the severity of the symptoms and on the results of this radiological survey.

[Tomodensitometry and spinal pathology].

The authors describe the possibilities and the limitations of the "scanner" in spinal pathology. Use of the third dimension and the certainty of absolute measurements, make this a very interesting method that can be applied to several areas of spinal pathology, especially traumatology and detection of primary and secondary tumors. It seems that this technique may be used in particular in the study of canal stenoses. There are future possibilities in view for segmentary densitometry, which gives better results than overall scintigraphy, especially in locating metastases. At present, studies are underway using contrast solution in order to study the possibilities of interpreting the content-container relationship.
