[MRI of the knee. Value of delayed sequences after intravenous injection of gadolinium].

A prospective study of delayed sequences after intravenous injection of gadolinium for knee MRI shows the similar results as from the literature: enhancement of synovial fluid after 30 minutes. Sixteen patients were studied mainly with gradient echo. This phenomenon improves the visualisation of the intraarticular structures like meniscus, cruciate ligaments, or cartilage. This study leads to use this technique in case of difficulties like postoperative intraarticular lesions.

[Chemolysis of intravertebral disk hernia and spinal syndrome].

The authors report a 31 year old patient who underwent L5-S1 chemonucleolysis. The prenucleolysis discogram disclosed intravertebral discal displacement. Severe spinal symptoms and development of geodes in the endplates adjacent to the treated disk occurred after the procedure. This case suggests that intraosseous discal displacement may be a risk factor for postchymopapain nucleolysis discitis and may contraindicate chemonucleolysis.

[X-ray guided puncture-aspiration of refractory calcifications of the shoulder].

Calcifying periarthritis of the shoulder may have either an acute or a chronic course. In both cases, direct puncture of the calcification shortens the natural history and facilitates and accelerates resorption in 50% of cases. The addition of a small amount of corticosteroid relieves the painful syndrome, with 80% good and very good results. The use of low doses of corticosteroid is particularly important in diabetics, patients with peptic ulcer and sportsmen. The puncture technique and the necessary precautions are described.

[Radiologic anatomy of the wrist].

Wrist imaging still relies first on plain X-Ray films, MRI allows excellent appreciation of the sculture of bones, ligaments, tendons and even nerves. C.T. is essentially useful in traumatology, while Wrist arthrography can be useful for detection of small ligament lesions.

[A criterion of validity of the x-ray computed tomographic measurement of femoral neck anteversion].

A wrong patient's position on the CT scan table may lead to mistakes in the measurement of femoral neck anteversion. We present an experimental demonstration using a wood manufactured femur model. If the slices are performed with flexion of the thigh, the measurement is lower than the true value. Thus, to check the measurement on the picture of added slices, it is necessary to have a superimposition of the pictures of the upper part and the lower part of the femur. Otherwise, the measure is wrong and the mistake depends of the direction of the shifting: --if the lower part of the femur is higher, the anteversion measure is lower than expected. --if the lower part of the femur is lower, the anteversion measure is higher.

[Anulography].

Despite new imaging modalities such as MRI, the discography remains useful, particularly as the first step of chemonucleolysis. The anulography corresponds to a technical error due to the wrong position of the needle during the procedure. We have noticed 32 anulographies on 1226 discographies done in our department, between 1985 and 1989. The anulography exhibits a typical pattern that must be diagnosed; if not, that can lead to a diagnosis mistake or a wrong therapeutic attitude. The needle of discography must then be repositioned.

[Double-blind study of the treatment of disc lumbosciatica by chemonucleolysis].

A randomized, double-blind study was made of 39 patients with discolumbar hernias that were unresponsive to medical treatment. They were treated either by nucleolysis with chymopapain (4 000 U of discase), or by discography followed by injection of distilled water as a placebo. After one month, treatment was found to be successful in 55% of cases undergoing nucleolysis and in 26% of cases receiving the placebo. The results after 3 months were 65% and 42%. respectively. After one month, the intensity of lumbar pain decreased by 44% on average in the group treated by chymopapain, and by 0% in the placebo group. Radicular pain decreased by 53% in the first group and by 26% in the placebo group, and improvement in Lasègue's sign was 51% and 20%, respectively. Analgesic treatment was reduced in patients treated by chymopapain: 65% of patients in the first group report some or much improvement in their sciatica, whereas this figure was 26% in the placebo group (p less than 0.02). Contralateral sciatica was observed in 3 patients of the placebo group. The average give in the disc one month after nucleolysis was 34% in the chymopapain group and 27% in the placebo group, without correlation with the clinical result. On average, patients were monitored for one year after nucleolysis, and during this year 6 patients from the chymopapain group were operated upon, compared with 10 patients from the placebo group. Although these results are at the limit of statistical significance because of the number of patients studied, they confirm the innocuousness and effectiveness of chymopapain in the treatment of discolumbar hernias.

Suprapubic ultrasonography in the follow-up of superficial bladder tumors.

40 patients with superficial (grade 1-3, stage 0) transitional cell carcinoma of the bladder were followed using urinary cytology, cystoscopy and suprapubic ultrasonography. Sonography detected tumors as small as 2.5 mm, but missed lesions that developed in the dome as well as flat anomalies associated with positive urinary cytology. Although, not a definitive alternative to cystoscopy, suprapubic ultrasonography of the bladder can, in selected cases, be used to widen the interval between endoscopic controls.

[Normal radiological aspects of a cemented total hip replacement].

The authors draw attention to the normal radiological appearances and the minor complication which may affect a cemented total hip replacement. Knowledge of these appearances enables the radiologist to define his attitude to the patient as well as his remarks on the case.

[Radio-transparent renal calculi and epithelial tumours. Contribution of ultrasound and CT scan to the diagnosis (author's transl)].

The aetiological diagnosis of lacunae detected by urography is uncertain in 10 to 20% of cases. Uric acid calculi larger than 2 cm in diameter can be demonstrated by ultrasonography, where they show as echogenic areas with conical shadows. Computerized tomography has wider possibilities: uric acid calculi are extremely dense and clearly visible, clots are not enhanced by contrast media, and the enhancement of epithelial tumours is of the avascular type.
