[Contribution of computed tomography to radiological investigation of the adrenals (author's transl)].
Computed tomography examinations of the liver, kidneys, and pancreas were conducted in 466 patients over a period of one year, and both adrenals were visualized in 94 p. cent of cases. The adrenals were investigated during examination of the posterior submediastinal space in certain types of cancer, and clinically silent adrenal metastases were demonstrated in 14 patients with bronchial or pancreatic cancer. When computed tomography is employed for specific investigation of the adrenals (22 cases), the technique varies (5 mm thick sections, "angioscan"), and results are comparable with those of early renal tomography, ultrasonography, and scintigraphy. Computed tomography provides clearer evidence of small tumors (less than 2 mm in diameter) and hyperplasia, and can provide images that are perfectly correlated with operative findings, but not always with the histology of the lesions. A method for exploring the adrenals radiologically, including the use of computed tomography, is proposed as a function of the biological nature and size of the tumors.
