Abstract

Background: The fourth most common cancer in the world, stomach cancer, is typically treated surgically. The 5-year survival rate for patients with advanced gastric cancer (AGC) ranges from 7 to 27%.

Aim and objectives: to evaluate the use of multi¬detector CT (MDCT) for the identification, localization, and assessment of morphologic features of early gastric cancer using MPR and virtual endoscopy.

Subjects and methods: The study included fifty (50) patients (30 men and 20 women at a referral Department of Diagnostic and Interventional Radiology, Al-Azhar University Hospitals in Cairo, between August 2020 and April 2022.

Results: The sensitivity of T1 was 81.8%, specificity of 96.6%, and total accuracy of 89.2%, and the sensitivity of T2 was 60.0%, specificity of 90.2%, and total accuracy of 75.1%, and the sensitivity of T3 was 66.7%, specificity of 93.8%, and total accuracy of 80.2%, and the sensitivity of T4 was 77.8%, specificity of 99.2%, and total accuracy of 88.5%. T1 was the most sensitive and T4 was the most specific.

Conclusion: Faster, easier, and more accurate stomach imaging has been made possible by CT 3D imaging software with several detectors and more reasonably priced data storage. The constraints of two-dimensional axial CT are overcome by multi-detector CT with MPR, and virtual endoscopy offers images that are comparable to traditional endoscopic imaging for the assessment of EGC. For the development of successful therapies, such as endoscopic mucosal resection or stomach resection, the precise preoperative staging of EGC and the early diagnosis of the illness are necessary.
