[Detection of left intraventricular thromboses. Comparison of 2-dimensional ultrasonics with scanography and scintigraphy with indium 111-labeled platelets].

Three methods of diagnostic imaging : bi-dimensional ultrasonography, scanography and 111Indium-labelled platelet scintigraphy were compared in 61 patients to detect left intraventricular thrombotic lesions, in order to determine their respective diagnostic values.

[Comparative study of scintigraphy, x-ray computed tomography and magnetic resonance imaging in the diagnosis of osteonecrosis of the hip and algodystrophy].

Effectiveness of modern imaging techniques were compared when used for diagnosis of the painful hip in adults, particularly the distinction between aseptic osteonecrosis and decalcifying osteodystrophy. Although a small number of patients were studied (5 cases of osteonecrosis and 5 of decalcification) the series was homogeneous (same investigator for each technique and identical equipment for each patient), and the different methods of investigation (conventional radiology, scintigraphy computed scanography CE 10,000 and 0.15 resistive NMR imaging) could be validly compared.

[Radiologic diagnosis of acoustic neurinoma. Apropos of 130 patients].

Diagnostic value of radiologic examinations was assessed in a homogeneous series of 130 cases of neurinoma of acoustic nerve seen over the last 10 years. Radiologic exploration is conceived and used at the present time for two purposes. Firstly, it enables selection of patients with suspected acoustic nerve neurinoma.

[Cineradiological study of the activity of sorbiperan on the gallbladder and colon (author's transl)].

The activity of sorbiperan was assessed during radiological examinations of 15 patients with hypomobility of the gallbladder, associated in some cases with atonic dyspepsia, and 25 cases of spastic colon with constipation and/or diarrhea due to diverticulosis, dolichocolon, sigmoiditis, or parasitosis. Patients with gallbladder dysfunction were examined radiologically before and after oral administration of 20 to 40 ml of sorbiperan, the dose varying as a function of bodyweight. In 3 patients, the hypermobility of the gallbladder provoked by this agent was greater than that observed with all usually employed products, in 11 cases the cholagogue produced an excellent effect, while in one case there was no observed effect.

[The contribution of whole body scanning in the exploration of haematological diseases. Preliminary study of 100 patients (author's transl)].

One hundred patients suffering from haematological diseases were explored by whole body scanning. The diagnosis was a lymphoma in the majority of cases (77). Analytical study of the images obtained was made on the basis of the various sections made systematically in the protocol of the study.

[Presentation of a simple apparatus enabling easier tomography in Hirtz's position (author's transl)].

By means of a smiple and hardly burdensome apparatus, owing to a tomograph with hypocycloidal or better spiral scanning a detailed study of the boney structures of the base of the skull can be obtained in a position which up to now has been reputed to be difficult.
