[Ultrasonographic guidance in diagnostic and therapeutic interventions in diseases of the internal organs].

A hundred fifty four invasive diagnostic and therapeutical interventions were made in patients with diseases of the abdomen and retroperitoneal space under ultrasonographic guidance. Various biopsies were performed in 139 patients; positive results were achieved in 120 (86.3%) cases.

[MRI diagnosis of soft tissue tumors].

MRI findings of 13 patients with soft tissue tumors (STT) are presented. There are were abnormalities, such as primary STTs of the hip in 5 patients, the back in 1, and the neck in 1, STT relapses of the hip in 2 and those of the back in 1. Two patients had chronic hip STT hematomas and 1 had hip STT metastatic melanoma.

[Invasive interventions guided by computerized tomography in the diagnosis and treatment of diseases of the internal organs].

Diagnostic punctures under CT guidance were made in 544 patients with diseases of the chest (n = 303), abdomen (n = 149), and retroperitoneal space (n = 92). In 87 patients, diagnostic punctures were combined with therapeutical manipulations and included aspiration and drainage of visceral organ cysts and abscesses. The proposed procedure of diagnostic biopsies under CT guidance could ascertain the morphological nature of a lesion in 90.
