Detection of esophageal carcinoma using single-photon emission computed tomography of thallium-201: a preliminary
1Department of Nuclear Medicine, China Medical College Hospital, Taichung, Taiwan.
Abstract:
The aim of this preliminary study was to evaluate the potential usefulness of thallium-201 (Tl-201) in detecting esophageal carcinoma. A total of 15 patients with esophageal carcinoma were arranged for Tl-201 single-photon emission computed tomography (SPECT) of the chest. Thirteen of the patients had epidermoid carcinoma and two had adenocarcinoma. Meanwhile, 7 normal controls without any history of esophageal disease also accepted Tl-201 SPECT of the chest for comparison. From the 15 patients, Tl-201 chest SPECT detected esophageal carcinoma in 13 (86.7%) but not in 2 (13.3%) patients with epidermoid carcinoma. In contrast, all 7 normal controls (100.0%) had negative results of Tl-201 chest SPECT. Our study showed that the Tl-201 chest SPECT scan could be considered as a non-invasive useful imaging method in detection of esophageal carcinoma.

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...
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...
