[Erroneous diagnoses of space-occupying processes of the kidney].

Renal masses are occasionally misdiagnosed because: (1) there are two lesions present; the important lesion (the mass) is small and hidden by the second, less important lesion, which is more prominent on the film; (2) there is misleading or insufficient clinical information: (3) previous results and films are disregarded and/or unavailable. In individual cases, differentiation between malignant and benign masses may be impossible, despite the application of all of the imaging modalities available.

[Percutaneous removal of an intravascular foreign body using a modified loop-snare technic].

Successful percutaneous removal of embolized intravenous catheters in two patients is described. The long duration of intravascular presence of the foreign bodies necessitated an adaptation of the familiar loop-snare technique. Percutaneous, transluminal retrieval is the method of choice for the removal of intravascular foreign bodies and should be performed in preference to surgical management whenever possible.

[Workload in a roentgenologic department 1978 and 1982. Changes--causes--consequences].

This is an analysis of the workload in the imaging department (number of exams and room time) from 1978-1982. The different changes are listed and explained. During the 4 years there has been a significant increase in Ultrasound, CT, and special procedures (invasive/interventional), whereas in conventional radiology the workload decreased. The origin of requests for diagnostic work-up was found to be not only due to the total number of hospital beds. It depends mainly on the type of clinical specialty making use of the beds. The consequences of these findings are discussed briefly.

[Test report on the system components for film processing by the middle-format technology].

Industrially developed accessories for use with medium-format equipment, which have been tested in a-clinical settery, were evaluated separately. The automatic mounting system (Delcadro) with the plastic mount (Cadrix) was accepted by all of our colleagues, and was rated as an advantage, with hardly any reservations. A slight modification is needed in the design of the mounts. This equipment would be a desirable addition to our own equipment for routine work. The daylight system (camera magazine and feeder) is, in principle, certainly a step in the right direction. Handling of the magazine proved to be too complicated and it was prone to malfunctions. Simplification, especially of the loading mechanism, would be desirable. The film feeder is designed for use with conventional roll processing machines. In our opinion, a feeder will always be put to full use if the films processed in this machine are mainly or exclusively of middle format; the darkroom is not permanently staffed and/or adaptation to an existing daylight system (large formats) has already been effected and/or depending on availability, both large and medium size-formats can be processed fully automatically as quickly as possible. However, if films of various formats are processed by an assistant in a darkroom, it is possible to deal with the total quantity of films faster than with a feeder by inserting 3 or 4 medium-format films (or 2 or 3 large-format films) simultaneously. The Heliomat film viewer offers impressive reproductions of 100 mm film on a glare-free glass screen.(ABSTRACT TRUNCATED AT 250 WORDS)

Workload of an imaging department in 1978 vs. 1982: changes, reasons, and resolutions.

The diagnostic radiology workload in a university-affiliated general hospital (primarily for inpatients) was recorded and analyzed as to number of examinations and room occupancy time of three different representative months in both 1978 and 1982. Examinations of conventional radiology decreased in number in all fields, markedly in the biliary system and GU tract and minimally in the chest and skeletal system, whereas ultrasound as well as CT rapidly increased in number and/or time. Special procedures (invasive/interventional) also increased in number and time with the exception of lymphography. Future planning of imaging rooms as well as training programs should be instituted based on these data.
