[Roentgenological diagnosis of the functioning of the cervical spine (author's transl)].

Basing on literature and 230 own functional examinations of the cervical spine, the author reports on a roentgenological method which satisfies practical requirements. In patients with degenerative and post-traumatic changes, the extent and localisation of the disorders of function and structure of the vertebrae can be determined by this method, enabling discovery of functional disorders in a large number of patients with clinical cervical spine syndrome. X-ray functional testing is shown to be a necessary complement to conventional x-ray diagnosis and clinical examination.

[Sonography in emergency diagnosis of the abdomen (author's transl)].

The article reports on 150 patients, 86 men and 64 women, aged between 16 and 90 years, who were subjected to sonographic examination directly after they had been admitted as emergency cases. In the group of patients under examination, the clinical disease pattern of acute upper abdominal complaints ranked first, followed (in the rate of incidence) by abdominal trauma and acute metabolic disease. In more than 25 % of the cases the decisive diagnosis was made on the basis of sonography only, so that there was no delay in deciding whether treatment should be initiated or whether the diagnosis required further differentiation. In another over 20 % of the cases ultrasound diagnosis contributed quite substantially towards arriving at the final diagnosis. The number of failures or unsuccessful examinations was about 2 % in each group. The rapid, mobile and risk-free use of sonography is emphasised. The results allow the conclusion that the share of ultrasound in the diagnosis of acutely and severely diseased patients should be increased and that sonography should in fact be placed first and foremost, as far as possible, among the diagnostic tools.

[The subphrenic abscess--possibilities and problems of ultrasound diagnosis (author's transl)].

The article reports on 37 patients subjected to sonographic examination because of the clinically suspected diagnosis of a "subphrenic abscess". In 7 of these patients, the diagnosis "subphrenic abscess" was arrived at via sonographic examination, and was confirmed in 6 cases by surgery and in one case by postmortem examination. The importance of ultrasound diagnosis for early identification of the subphrenic abscess is discussed and the high rate of accuracy is underlined. The author emphasises that even discreet x-ray film symptoms should prompt immediate ultrasonic examination.

Early X-ray detection of colonic and rectal tumours in European hamsters.

Three groups of European hamster (EH) (Cricetus cricetus L.) were treated subcutaneously every two weeks for life with 1/10 or 1/20 LD50 DMH, while two other groups served as controls. Twelve weeks after commencement of treatment, radiological examinations of the colon and rectum were begun. The double contrast method was used. In this way it was possible to detect the earliest neoplastic alteration to take place in the above sites. This occurred in the 26th treatment week and was diagnosed as an adenocarcinoma. The technique used is simple, as well as being suitable for large numbers of animals. In addition, it allows for early experimental analysis of results in respect to latency period, growth rate, incidence and location of tumours.

Diagnosis of experimentally induced bronchogenic tumours in the european hamster with bronchographs.

Four groups of European hamsters were treated subcutaneously once weekly for life with 1/20 or 1/40 the diethylnitrosamine LD 50. Three animals from each treatment group and the two control groups were examined every three weeks by means of bronchographic technique. In four of the animals the bronchograms showed early neoplastic alterations of the bronchial system. The results demonstrate that bronchography is a suitable method for the diagnosis of bronchogenic tumours in the European hamster and that it also allows for the detection of displacing neoplasms of non-bronchogenic origin in the region of the tracheal bifurcation.

[Radiculo-tomography for lumbosacral myelography (author's transl)].

The use of tomography can increase the value of lumbosacral myelography in certain circumstances. Post mortem studies have resulted in standardisation of the examination, which will combine optimal diagnostic information with the least amount of effort and with an acceptable amount of stress on the patient. 110 tomographic examinations were performed amongst 680 lumbosacral myelograms (Dimer X). On the basis of this experience, the value of this procedure is illustrated from various points of view and its indications are discussed.

X-ray enlargement modified for use in experimental animal science.

The primary enlarged x-ray image is produced by a reduction of the focal-film-distance to 80 cm at a given focal size of 0-15 mm. The advantages of this technique as compared to conventional x-ray methods are exemplified with x-ray images from the shoulder joint of a European hamster, a pseudoarthrosis in the foreleg of a beagle, and a renovasography of a rat. The principles of the technique and its significance for investigations using small laboratory animals are discussed.

Radiological detection and sequential observation of experimentally induced bladder tumours in the European hamster.

FOUR GROUPS OF EUROPEAN HAMSTERS (STRAIN MHH: EPH) were treated subcutaneously once weekly for life with 1/20 or 1/40 the LD(50) of DBN while another 2 groups served as controls. Three animals of each group were x-rayed every 2 weeks after i.v. injection of the contrast agent Urographin. By means of cystograms tumours of the urinary bladder were detected between the 20th and 26th weeks after beginning treatment when they had reached a diameter of 1-2 mm; their development was subsequently observed by periodical x-ray examinations. The technique described is simple and provides a valuable means for obtaining additional in vivo information concerning latency period, growth rate and identity of experimentally induced primary urinary bladder tumours in the European hamster.
