[The value of angio-CT for staging, observation and treatment of acute pancreatitis (author's transl)].

Compared with ordinary CT, angio-CT in mild, moderate or severe pancreatitis provides better demonstration of parenchymatous necrosis and more accurate identification of the organ in the presence of oedema, necrosis or haemorrhage in the retroperitoneal space. Follow up observations of these changes assist in the choice of treatment, such as was not available previously.

[Computer-assisted tomography, B-scan sonography and cerebral angiography in obliterations of the carotid artery (author's transl)].

The real-time-B-scan is a new and essential method for diagnosing carotid stenoses. Whereas computer-assisted tomography shows only a minor sensitivity for detection of obliterations of cervical arteries, B-scan sonography has high sensitivity and specificity. B-scans should be increasingly performed both after uncertain clinical and computer tomographic findings prior to angiography of extracranial cerebral vessels. A more stringent indication for angiography and thus avoidance of investigational and irradiation risk can be achieved. Wide use of B-scan sonography may, through early recognition of carotid obliterations, lead to prevention of cerebral insults as patients can undergo vascular surgery at an early stage.

[Computer tomography in the diagnosis of adrenal disease (author's transl)].

Computer tomography of the adrenals was performed on 35 patients. Abnormal findings were noted in 19, histologically confirmed in 14. In the course of localization of endocrine processes, as well as in elucidating suspected tumours, a normal adrenal gland can be visualised by computer tomography in over 90% of instances, and lesions detected if greater than 0.5--1.0 cm in diameter. It should be used after all clinical and biochemical tests and conventional radiological measures have been employed, invasive angiography being reserved only for special problem cases.

[Staging and follow-up of acute pancreatitis by angio-computer tomography (author's transl)].

First results of angio-computer tomography (CT) in the diagnosis of acute pancreatitis are reported. Angio-CT allows the display of changes occurring during hemorrhagic-necrotizing pancreatitis in a much more precise manner, than has been possible up to now. Enlargement of organs, changes of contours, exudation and hemorrhage into the retroperitoneal space can be diagnosed; after bolus injection of radio opaque viable and well perfused tissue may well be differentiated from necrotic tissue.

[CT scanning of the kidneys--efficiency and diagnostic value (author's transl)].

Shorter scan times have been shown to improve image quality in Computerized Tomography. With the help of bolus injected contrast medium blood vessels and well vascularized structures in the kidneys can be visualized. In this report normal anatomy and pathological changes of the kidneys are described and demonstrated. CT was found to be a reliable method in diagnosis of various kidney diseases especially involving space occupying lesions, and it reduces the need of invasive techniques such as angiography. Nevertheless intravenous urogramm should be the initial examination in kidney disorders.

[CT examination of the organs of the minor pelvis (author's transl)].

Since the organs of the minor pelvis are not characterized by any significant differences in density, it is not possible to differentiate between neighbouring structures. This underlines the special importance of fatty deposits and fatty tissue margins with their clearly lower density, as structures outlining the pelvic organs. However, there are individual and constitutional differences in the manner of development of these fatty outlines, so that the ability to distinguish between the various pelvic structures may be different from patient to patient. Structural analysis is facilitated by marking the hollow organs with contrast medium, and generous use should be made of this possibility. With modern computer tomographs, minor details can be detected which may be as fine as the smaller vessels, provided these vessels are embedded in the fatty layers, However, it is very difficult to differentiate them from the nerves, lymphatics tissue and connective tissue septums; this requires an accurate knowledge of anatomy.

[Computer tomography on the pancreas. A diagnostic extension from the surgical aspect (author's transl)].

125 patients were subjected to computer tomography on account of suspected pancreatic disease. 48 patients were operated on--the computer tomography (CT) diagnosis was confirmed in 85.5% of the cases. Acute pancreatitis can be detected by CT if it is accompanied by an appropriate enlargement of the organ. Chronic pancreatitis can be recognized by deformations of the organ, calcifications or formation of pseudocysts. Pancreatic carcinoma is recognizable when it is larger than 3 cm accompanied by a change in the shape of the organ or if infiltration of neighboring structures has occurred. Computer tomography offers patients a safe, non-invasive method of performing follow-up examinations at short intervals.

[Computed axial tomography (cat) in the diagnosis of diseases of the heart and aorta (author's transl)].

Computed axial tomography (CAT) was used in 70 patients with diagnostic problems centering on the heart (47 patients) or the aorta (23). The method proved suitable for the diagnosis, differential diagnosis and serial control of pericardial effusions and also well demonstrated intracardiac tumours. Aortic aneurysms are also easily demonstrated and their extent can be exactly defined. But aortic wall dissection and stenosis of arteries arising from the aorta are not visualized and therefore require angiography.

[Computer tomography of the facial skeleton and pharyngeal space (author's transl)].

Seventy-five patients with histologically confirmed abnormalities of the facial skeleton and pharynx, including the mouth and base of the tongue, were examined by computer tomography. The advantages of simultaneous demonstration of the soft tissues and bones in localised space-occupying lesions are pointed out. Accurate comparison between pre-operative descriptions and findings at operation in 30 cases showed high diagnostic accuracy. Conventional, multi-dimensional film tomography is being increasingly replaced by computer tomography.

[Computer tomography in the diagnosis of local recurrences after resection for carcinoma of the rectum (author's transl)].

Presacral or pelvic floor tumour recurrence after abdomino-perineal resection for rectal or anal carcinomas has not been amenable to early radiological diagnosis. Computer tomography is a procedure which can demonstrate recurrences of two to three cm. Within the pelvis with certainty. The reliability of the method has been demonstrated in 27 patients suspected of having recurrences. The effect of demonstrating or excluding a recurrence on subsequent treatment is discussed. The value of computer tomographic examination of the pelvis for demonstrating the position and extent of a recurrence, the displacement of neighbouring organs, destruction of the pelvis and involvement of iliac lymph nodes is shown.

[Radiological diagnosis of colorectal polypi and carcinomas which have not progressed].

Provided examination conditions are optimal, we are now able to detect changes of the wall of the colon from about 5 mm diameter upwards and thus to further clarify the diagnosis and to initiate appropriate treatment. Hence, the demand for early or timely diagnosis can be met by means of x-ray diagnosis in respect of processes of the colon.
