Abstract:
A comparison is made of the results of CT scanning and MIBG scintigraphy in the localization of phaeochromocytoma. In 21 out of 24 patients with clinically diagnosed phaeochromocytoma in the University Medical Hospital, Groningen in 1983-1990, MIBG scintigraphy provided accurate localization, while in 16 out of 18 patients with phaeochromocytoma who underwent CT scanning a correct localization was obtained. False negative results were mainly present when lesions were smaller than 2 cm. There were no false positive results. It is concluded that the sensitivity of the two methods in the localization of phaeochromocytoma is about equal. The use of one of the methods rather than of both is advised.

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...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
