A total of 112 patients with non-Hodgkin's lymphomas of abdominal and
retroperitoneal localization were examined by the ultrasonic and x-ray
methods, in 83 of them x-ray computer-aided tomography was used. Angi
ographic examinations and puncture biopsy monitored by US or x-ray CAT
were carried out if indicated. The authors discuss the problems of ul
trasonic and x-ray semeiotics of the lymphomatous involvement of the l
ymph nodes, spleen, gastrointestinal tract. They claim that USE, permi
tting the specification of further plan of examination of each patient
, and x-ray examination as a method to assess the gastrointestinal sta
tus are the optimal methods for the primary diagnosis of non-Hodgkin's
lymphomas. US data may prompt further application of x-ray CAT, whose
results will supplement the US findings. Angiographic examinations sh
ould be carried out only in the mast difficult diagnostic situations,
bearing in mind the invasive nature of the method and its high price.
