[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.

[Lymphography--farewell to a routine method in pretherapeutic staging?].

In view of the steep decline in the number of lymphangiographies (LAG) performed, the authors try to correlate the relevance of this radiological staging method with that of computed tomography and the histological results of lymphadenectomy. The diagnostic accuracy of both methods (LAG and CT) is comparable (71.4% and 70.6%, respectively). In respect of specificity, CT is superior to LAG (this superiority is due to the method employed) to the tune of 88.2% for CT vs. 58.8% for LAG. If there is a large proportion of early tumour stages, CT is inferior to LAG with regard to sensitivity (52.6% and 63.2%, respectively). Lymphangiography can no longer be recommended in case of intrapelvic urological and gynaecological tumours. It is only indicated, as before, in staging diagnosis of seminomas of stage No of after CT and of Hodgkin's lymphomas of stage II B. In non-seminomas LAG is exclusively a service performed for the benefit of the surgeon wishing to have a contrast medium staining of the lymph nodes. In future, LAG can be offered only in centres having a sufficiently large group of oncological patients to look after.

[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)
