[Para-pleural lung lesions: diagnostic value of sonography versus computerized tomography].
UNLABELLED: 45 patients with pleural and/or peripheral lung lesions detected by chest radiography were examined by chest ultrasound. A chest CT-scan was obtained as a reference method afterwards. In 43 pleural or peripheral lung lesions we found corresponding results comparing size, invasivity and nature comparing the two diagnostic methods. In 35 of 41 cases an ultrasound (US)-guided needle biopsy confirmed the preliminary diagnosis suspected after sonography of the chest. Six needle biopsies allowed no definite diagnosis. Two patients developed a pneumothorax that required drainage after US-guided needle biopsy. CONCLUSION: Real-time sonography of the chest and chest CT-scans are complementary methods examining pleural and peripheral lung lesions, corresponding results are demonstrated in respect of location, size, invasivity and nature of the lesions.

[Changes in the lungs and pleura following chemoembolization of liver tumors with mitomycin-lipiodol].
The authors performed 68 liver embolizations in 51 patients. As selectively as possible, Lipiodol, to block the capillary bed, and a chemotherapeutic agent were injected into the liver tumors. A CT performed 24 hours after treatment showed the distribution of the contrast medium which is also an indicator of the distribution of the chemotherapeutic agents. It was found that the contrast medium had accumulated not only in the liver but also in the lungs. Here, four different degrees of accumulation were found, according to the amount of Lipiodol used. Embolization of the liver thus involves potential hazards for the lungs, such as microembolisms, pneumonia, and toxic effects of the chemotherapeutic agents.

[Combination fractures of the pelvic girdle: comparison of CT with the conventional pelvic image].
102 polytraumatised patients with pelvic fractures were studied by conventional x-rays of the pelvis as well as by computed tomography to obtain detailed information on type and degree of the fractures. We paid particular attention to acetabular and sacral fractures and combinations thereof. We found that only computed tomography enabled us to precisely define type and degree of pelvic injury. We thus draw the conclusion that each patient with proven or suspected pelvic injury should be subjected to a CT study to enable the surgeon to plan his therapy-conservative or surgical-to the best benefit of the patient.

[The inverted cockade sign. An indication in CT of an impending rupture of an abdominal aortic aneurysm].
A new CT-sign as a pointer to the imminent rupture of an abdominal aortic aneurysm is described: the enhanced shell of the thrombus of the aneurysm. This sign is caused by bleeding into the thrombotic layer.

[Appendicitis in the computed tomographic image].
29 patients with unclear symptoms in the right lower abdomen received a CT-examination in an attempt to prove or exclude appendicitis. In almost all cases it was possible to demonstrate the inflammatory process in the appendix itself (size of the organ). More diagnostic information was obtained by careful examination of the accompanying reactions of the cecum, the mesenteriolum, the fascia and other neighboring organs. Thus CT is a valuable tool in the diagnosis of appendicitis and facilitates the decision for or against an appendectomy, which otherwise may be very difficult.
Acute Disease↗
[The scimitar syndrome in computed tomography and intravenous subtraction angiography].
A case of scimitar syndrome is reported in which the diagnosis was first suggested on chest radiograph. The diagnosis was confirmed by computed tomography (CT) and intravenous digital subtraction angiography (DSA). CT and DSA seem to be able to evaluate the structure and distortion of the lung and the vessels.
Angiography↗
[Benign segmental bronchial obstruction in computed tomography].
The benign segmental bronchial obstruction--mostly discovered on routine chest films--can well be diagnosed by CT. The specific findings in CT are the site of the bronchial obstruction, the mucocele and the localized emphysema of the involved segment. Furthermore CT allows a better approach to the underlying process.

[Rounded atelectasis in the computerized tomographic image].
The rounded (helical) atelectasis is a benign alteration of the lung that can be diagnosed by radiography. Besides the criteria of the chest x-ray film and of the conventional tomogram (shadow close to the pleura, located mainly in the inferior lobe, with "comet-sign" and pleural thickening) the most important finding in computed tomography is the "octopus-sign".

[Origin and course of renal arteries. A CT study for determining optimal projection plane in renal artery angiography].
In an attempt to optimize renal artery angiography we performed a CT-study. In 500 patients we determined the angle at which the arteries arise from the aorta and their course. Both renal arteries are in one plane, which is tilted 13 degrees ventrally on the right and 13 degrees dorsally on the left. More distally we found an angle of 35 degrees on the right and an angle of 29 degrees on the left in the dorsal direction. These findings were independent of age and sex of the patient.
