[Morgagni's hernia erroneously interpreted as a lipoma].

The author describes the problems of properly diagnosing Morgagni's hernia via non-invasive x-ray examination. A case history is reported as an example. Diagnosis can be confirmed, especially with small hernias which do not contain parts of intestine or liver, by additional subtle sonography and high-resolutien computed tomography.

[Changes in scintigraphically determined regional blood volume in coronary patients treated with the new substance teopranitol].

To evaluate the effects of the new compound teopranitol (KC 046) on blood volume distribution scintigraphic measurements were performed in 10 patients with coronary heart disease. The data were compared to the results in 10 untreated patients with coronary heart disease. The differences in blood volume distribution were calculated by the ratio of the impulse rates thorax/abdomen, thorax/thigh, thorax/shank and heart/total impulse rates assessed by scintigraphy, following in vivo labeling of red blood cells with 99m-Tc, before and after i.v. injection of 0.04 mg KC 046/kg body weight. A significant decrease of the ratios could be found, whereas the data in the untreated group did not change significantly. It is concluded from these results that the clinical improvement of the patients with coronary heart disease treated by KC 046 is caused by a significant shift of blood volume from the thoracic region into the abdomen and the legs, thus decreasing the preload of the left ventricle.

[Time related changes in the density of liver metastases after contract (a densitometric investigation with computer tomography) (author's transl)].

The present investigation is concerned with the increase in density of normal liver parenchyma and of liver metastases after the injection of contrast. Following a bolus injection (5 ml./sec.) of 390 mg. I/kg. body weight the difference in density between metastases and liver parenchyma at one minute after the injection was twice the pre-injection differential. This lead to a better differentiation of metastases from artefacts, and the ability to demonstrate liver metastases with a diameter less than 1 cm.. Computer tomography is likely to be better than sonography or liver scintigraphy. Some metastases show peripheral concentration of contrast with an apparent diminution in size at 5 to 10 minutes after the injection of contrast. Further investigation might lead to the ability to recognise the type of metastases where the primary tumour is unknown. After a plain film, computer tomography following injection of a suitable contrast medium is recommended.

[The value of CT in the differential diagnostic evaluation of masses in the left upper abdominal quadrant (author's transl)].

Analysis of criteria used in the evaluation of left upper abdominal masses seen on CT. A very critical approach is recommended concerning the diagnostic reliability of density measurements and contrast-enhancement. The configuration of the mass and its relationship to the neighborhood seem to be more important aids for a reasonable differential diagnosis.
