Background:
The possibilities and limitations of computer tomography (CT) examination for detecting primary gastric cancer tumors have been poorly understood. The aim of the present study was to evaluate the pre-operative assessment of gastric cancer tumors using 32-multidetector row-CT.
Patients And Methods:
A prospective study of the pre-operative assessment of gastric cancer tumors using 32-multidetector row-CT was carried out. Seventy-four patients with adenocarcinoma of the stomach (T1 tumors, 38; T2 and T3 tumors, 36) underwent abdominal CTs to assess the feasibility of using MD-CT to assess primary lesions.
Results:
In 35 (47%) out of the 74 patients, the primary lesions could be detected on 2-D images obtained by CT. In these patients, virtual endoscopic images of these tumors could be created. Twenty-seven advanced cancer tumors (75%) were assessed based on 2-D CT images and 27 larger tumors (>40 mm) (69%) were assessed based on 2-D CT images. Significant differences were found with respect to depth of tumor (p<0.0001) and tumor size (p<0.0001) between tumors that could or could not be assessed on MD-CT.
Conclusion:
The findings of the present study show that CT assessment of tumors is feasible in patients with advanced gastric cancer. Future studies are required to fully explore the ability of MD-CT to assess tumor volume in advanced gastric cancer cases and to determine the optimum application of this approach.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

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...
