[Functional assessment of the hepatic arterial blood flow by pharmacoradiography (author's transl)].

By means of celiacography it was possible to demonstrate that parenteral medication with parathormone creates a selective dilatation of the liver vessels in man, provided that they are dilatable. This hemodynamic hormone effect could not be traced in the other mesenteric vessels. The increase of portal hypertension resulting from cirrhosis leads to a loss of the dilating ability of liver vessels. This regressive reaction is well demonstrated on the parathormon-celiaco-gram. Thus a functional assessment of the hepatic blood flow is possible. The extent of the dilatability of the liver artery seems to be of great importance for the prognosis and indication of the porto-systemic shunt-operation. Moreover we could show that an increase in the liver perfusion demonstrates pathologic liver processes in a better way.

[Responsibility of the radiologist in gastric studies].

The radiologist's responsibility for the investigation of the stomach. The most successful results in the gastro-intestinal examination is obtained by combination of ray-examination (double contrast method) with gastroendoscopy and biopsy. It is of main importance, that the X-ray examination is performed at the beginning of all diagnostic step. The radiologist is obliged to use the best examination method. Therefore an economic standardized process of diagnosis is recommended which can take place also at the radiologist's consulting room. The high accuracy which can be reached by the recommended proceeding justifies the little additional expenditure of time and material.

[Typical changes of the intestinal wall due to oral stenosing processes (author's transl)].

Two different changes of the intestinal wall, which seem to be of stenotic orgin, can be observed prä-stenotically. One of these changes is represented by diverticulosis, whereas the other is the so-called ischaemic-ulcerous lesion of the mucosa. The latter accompanying disease supplies highly important preoperative information. This condition can be diagnosed practically exclusively by the roentgenologist. In many cases, stenosis makes endoscopic assessment impossible. Diverticulosis is of theoretical interest in this connection. The article goes into the possible aetiology of the changes. Two typical cases underline the importance of the diseased conditions under discussion, which are relatively rare, as is evident from a statistical evaluation of the author's case material.

[Diagnosis of liver and biliary diseases with 99mTc-Hepatobida (author's transl)].

Application of 99mTc-Hepatobida has turned out to be a convenient diagnostic screening method in liver and biliary disease. Side effects are unknown, thus patients with iodine allergy or other forms of allergy, as well as patients harboring autonomous adenomata of the thyroid, and severely ill patients will tolerate this substance well. 99mTc-Hepatobida may be applied even in the presence of highly elevated levels of plasma bilirubin and thus will yield diagnostic results in all forms of hepatic disease if findings are monitored repeatedly. In addition screening with 99mTc-Hepatobida will in some cases suffice to establish the diagnosis and thus forgo more complicated diagnostic procedures.

[About the so-called ischemic-ulcerative innerwall lesion of the bowels proximal to intestinal stenoses (author's transl)].

The ischemic ulceration resp. the ischemic necrosis of the intestine's internal wall located proximal to an obstruction is a rare complication. At present this diagnosis is established by the radiologist alone. The knowledge of this disease--which is at the time being abscure in its origin--is of great importance to the surgeon, who has to try to resect both, the obstructes and the ischemic-ulcerative regions, in order to avoid insufficiency of the anastomosis postoperatively. The oral border of the alteration can be determined by a frozen section during the operation. In this connection the fatal complications of total necrosis of the large and small intestines resp. is demonstrated for the first time.

[The radiological diagnosis of shock lung (author's transl)].

So-called "shock lung" has typical pathological findings; radiologically it is characterised at first by interstitial, late by alveolar pulmonary oedema. This has been shown by a number of case reports. In addition to shock, however, certain intoxications and all forms of left heart failure produce the radiological changes of pulmonary oedema. Transient hyperhydration of the lungs following infusion therapy causes signs of pulmonary oedema which disappear as soon as the fluid balance becomes normal. The radiographic findings of pulmonary oedema correlate well with the intensity and extent of the pathological changes. The radiologist is therefore in a position to evaluate the severity of the shock lung; this is a valuable addition to the clinical findings and the results of physiological tests and blood gas analysis. It has to be emphasised that the radiological changes appear at an early stage, in any case much sooner than the clinical features. Radiological findings may be present without abnormalities on oscultation or percussion. Radiographs of the lungs are therefore indicated in all patients who may be subject to shock lung, particularly if they suffer from undiagnosed hyperventilation.

[About the advantages of the sonographic diagnostic in the field of the radiologist (author's transl)].

1. Ultrasound techniques as a new diagnostical method are included in the work and administration of an already existing institution of a central hospital, i.e. the X-ray department. Avoiding a special organizational unit in the hospital or an organization depending on a department which e.g. a gynecology could not be asked to undertake (considering the amount of work and qualification needed) means an advantage from the economic point of view. 2. The radiologist is able to learn the interpretation of the B-Scan of the ultrasound method very quickly because the visual imagination necessary to handle both methods is the same. 3. Sonography is an important supplement for radiological diagnosis. 4. Suspecting a lesion of an retroperitoneal or intra-abdominal organ sonography can be used as the first check-up. Renal sonographie could prove to be a screening-method. Often the ultrasound finding indicates the further diagnostical procedures which are successful, saving X-rays and time. Under certain circumstances X-ray investigations can possibly be avoided. Considering the last two points would mean for the future that the radiologist indicates the diagnostical method to be used - not only the ultrasound but also the X-ray method. Five cases demonstrated confirm this conclusion.
