[The marking of the gastrointestinal tract in computed tomography: experiences with a barium sulfate contrast medium (Micropaque CT)].

Micropaque CT, a new suspension of barium sulphate, has recently become available for clinical use in abdominal CT. The attenuation of the 1.5 per cent solution, measured in vitro, was 222 HU (without artifacts). In about 45 per cent of the clinical examinations artifacts occurred which, however, were not disturbing. Sufficient opacification of stomach and bowel was achieved in 65 per cent. 55 per cent of patients found the suspension pleasant to take, ten per cent complained of mild diarrhoea. Micropaque CT is particularly suitable for upper abdominal CT in outpatients.

[Granular cell tumor (Abrikossoff tumor) in the digestive and respiratory tracts--two new observations].

Granular cell tumor is one of the rare neoplasms of presumptively neural origin of the alimentary and respiratory tracts. Two new endoscopically and histologically confirmed observations are presented. The radiological appearance (conventional radiography and x-ray computed tomography) is described in detail and compared with the findings published in the literature.

[Differential diagnosis of adult respiratory distress syndrome in the roentgen image].

The radiologist makes an important contribution to the diagnosis and follow-up monitoring of ARDS by supplying a stage classification of the disease pattern and by drawing early attention to complications. However, the list of differential diagnoses is so long that in all cases accurate radiological assessment can be performed only if the clinical data are known. If not, all the radiologist can do is to list a number of suspected diagnoses that are more or less probable.

[Experimental studies on shock-wave cholelithotripsy].

An experimental device for extracorporeal shock-wave cholelithotripsy has been tested. It is characterized by an electromagnetic acoustic source and focussing of the stones by ultrasound. After in vivo experiments with 45 calculi twelve pigs, seven of them with surgically implanted human gallstones, were treated. Most concrements were only partially disintegrated. A combination with MTBE-litholysis improved the results. The by far most important complication we saw were extensive hemorrhages in the basal segments of both lungs. The quite different anatomy suggests that shock-wave cholelithotripsy in man will not be accompanied by severe lung lesions. Patients suffering from gallbladder stones should be treated in the prone position and in deep inspiration. A maximum of 2,000 shock-waves with an energy of 18 to 20 kV should be administered in one session.

[Indirect lymphography: indications, technic, clinical results].

Indirect lymphography with iotrolan makes it possible to demonstrate the lymphatic pathways with minimal invasiveness. This opens up new possibilities in the differential diagnosis of chronic swelling of the extremities. The typical radiological appearances make it possible to diagnose various types of lymphoedema and lymphangiomatous malformations. The method also promises to be useful in elucidating the pathogenesis of various types of swelling of the extremities.

Magnetic resonance measurements of the deviation of the angle of force generated by contraction of the quadriceps muscle in dogs with congenital patellar luxation.

OBJECTIVE: To measure the quadriceps angle (Q-angle) in dogs with congenital patellar luxation using magnetic resonance (MR) methods. STUDY DESIGN: Prospective clinical study. ANIMALS: Thirty-eight client-owned dogs. METHODS: Thirty-eight dogs were examined and placed into the following groups based on the degree of patellar instability: normal, grade I, grade II, and grade III. MR images of 37 pelvic limbs without patellar instability, 33 pelvic limbs with patellar luxation, and 6 limbs with cranial cruciate ligament (CrCL) rupture were made. The Q-angle was calculated using trigonometric methods based on MR images. Limbs with patellar luxation were compared with normal stifles and stifle with other disorders. RESULTS: The average Q-angle of the normal group was 10.5 degrees (24.9 degrees to -2.0 degrees ). The grade I group had an average Q-angle of 12.2 degrees (28.8 degrees to 2 degrees ), the grade II group 24.3 degrees (44.6 degrees to 7.7 degrees ), and the grade III group 36.6 degrees (51.4 degrees to 15.6 degrees ). The average Q-angle of limbs with an isolated CrCL rupture was 19.3 degrees (34.7 degrees to 3.9 degrees ). CONCLUSION: MR images can be used to make exact calculations of the Q-angle. CLINICAL RELEVANCE: MR images can be used to quantify the degree of patellar luxation.
