Purpose: A possible complication in regard to osteosynthetic treatment of a lower radius fracture with a locking plate is perforation of the articular surface by screws or a malpositioned ulnar fragment. In order to create good conditions for a homogeneous, reproducible X-ray picture for post-operative imaging control, an appliance for the production of standardised X-ray views has been devised., Materials and Methods: The X-ray device was constructed at an angle of 20 degrees to the camera. The arm was positioned on the appliance in the side beam path, in shoulder adduction as well as in the dp-beam in 90 degrees abduction of the shoulder., Results: Through standardisation of the X-ray technique the appliance it is able to supply comparable and reproducible X-ray images. In practice, the representation of both the joint gap and the bolt in the resulting image could be improved., Conclusions: Better and comparable picture series can be created by standardisation of the imaging technique using this X-ray device.

Guidelines and standards supplementing the German "Röntgenverordnung" initiated a complex system of quality control in diagnostic radiology. Cost and profit are analysed for two hospitals of comparable size (Klinikum Buch and Klinikum Nürberg). The considerable expenses that must be incurred for measuring devices, equipment, working time and extra charges on the one hand, are the items that are opposed to achieving a higher image quality and dose reduction on the other. Public quality control enables to demonstrate the quality and to optimise imaging procedures in diagnostic radiology. A critical evaluation of the results of quality control suggests further developments. We should consider larger time intervals for quality tests in some cases, while focussing on techniques with high radiation exposure, e.g. computed tomography, where dose reductions are highly effective.

The urographic results obtained in 14 patients with tumors of the renal pelvis are compared with those of computer tomography (CT), and the diagnostic possibilities emerging from CT are described. CT is superior to urography and angiography not only in the discovery of renal pelvic tumors but also in their further differentiation. In addition, CT gives information in case if bilateral processes and lymph node metastases. Nonetheless, intravenous pyelography continues to hold the first place in the diagnosis of pathological processes of the renal pelvis. This holds both for tumor detection and suspicion and for indirect signs, namely the "mute" kidney or hydronephrosis. Angiography is less information with renal pelvic tumors, and with ultrasonic diagnostics there is no sufficient experience up to now.

Acquired displacements of the urinary bladder refer to intrapelvic pathological anatomy. These alterations of the bladder are predominantly detected via an initial radiologic study with intravenous urography or suprapubic pelvic ultrasonography. According to their clinical incidence displacements of the bladder can occur in: pelvic space-occupying lesions; displacements in musculo-fascial defects of supporting structures as well as in extirpation cavities of the small pelvis; extrapelvic space-occupying lesions. Herniation, prolapse and descensus of the bladder can be accurately diagnosed by correct examination via intravenous urography. The diagnostics of pelvic and extrapelvic pathogenetic causes require the complex application of all methods of diagnostic imaging, the value of which is determined by clinical diagnosis and by the choice of an appropriate therapy.
