Use of CT in the Placement of Heat Monitoring Thermocouples for Hyperthermia Therapy

Abstract
In 12 cancer patients undergoing hyperthermia therapy, computed tomography (CT) was used for placement of thermocouples within the tumoral tissue. Tumors were located in the thorax, abdomen and pelvis. CT provided accurate angulation of the introduction angiocatheter and the ability to choose the shortest and safest path. The cross-sectional display was especially helpful in placing the heat monitoring thermocouple within the active part of the tumor rather than a necrotic portion. CT probably is superior to fluoroscopy in this regard.
