[Ultrasonography in the diagnosis of hyperparathyroidism].

Ultrasonography is a direct method of representation, giving various advantages over other methods in the examination of parathyroid glands: it is rapid, non-radiation and economically undemanding. Dynamic examination by means of the linear electronic transducer of 3.5 MHz and the use of water path was used in 37 patients. In 7 patients with primary hyperparathyroidism was the examination rapid and the pictures of the adenomas were persuasive. In 30 patients with secondary hyperparathyroidism were found characteristic pictures, if the glands were enlarged to 8 mm or more. For the diagnosis of smaller glands a high resolution transducer will be necessary. Histological finding was available in 21 patients undergoing operation, and easily available method and it is therefore the procedure of the first choice.
