title: [The diagnosis of tumors of the chromaffin tissue by magnetic resonance tomography].
abstract: To study the potentialities of MR tomography in the diagnosis of chromaffin tissue tumors and to elaborate a number of quantitative diagnostic criteria, 26 patients with pheochromocytoma were examined. All the patients were subjected to x-ray computer-aided tomography of the adrenals. In 24 of them, the diagnosis was completely confirmed on histological examination of the excised tumor. The control group consisted of 19 healthy persons. All the investigations were performed on a MR tomograph BMT-1100 manufactured by Brucker Company (FRG) (0.235 T) according to the SE technique, with TR being 2 s and TE 34 ms. The visual picture together with a number of quantitative parameters (the time of spin-spin relaxation--T2, the index of relative signal intensity) were appraised. The method is shown to be highly informative in the diagnosis of pheochromocytomas, particularly of extra-adrenal site. In addition to a more prolonged T2, the high values of the index of relative signal intensity appeared very suggestive, especially on the 3d and 4th echo images.
