Abstract:
A total of 56 patients underwent preoperative high-resolution sonography (4 MHz); 33 had additional computed tomography (4 mm slices, contrast material as drip infusion) to localize abnormal parathyroid tissue in primary hyperparathyroidism. The sensitivity of sonography was 48% compared to 38% for computed tomography. The efficiency of both techniques was mostly dependent on size and location of the parathyroid. Computed tomography was superior in detecting ectopic parathyroids. Because of its low sensitivity sonography is only of facultative importance as a localization procedure for primary hyperparathyroidism. Computed tomography is indicated only for localizing ectopic parathyroid tissue after initial operation has failed.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
