Multidetector computed tomography in the evaluation of gastric malignancy; A multicenteric study

Abstract

Objective: The aim of this work is to highlight the diagnostic value of multidetector CT in assessment of gastric malignancy compared to surgical and pathological results. Method: A Multicenter study was conducted from (October 2011–March 2014). Thirty-five patients were included, eight females and twenty-seven males with mean age 50 years (34–81). All patients were subjected to; Full history taking and physical examination, Multidetector Computed Tomography (MDCT), and Upper Gastro intestinal endoscopy. Triphasic CT was used using oral and IV contrast where scanning at arterial phase cuts were taken after 15 s followed by portovenous 20–25 s after the arterial phase. Results: 74% of Lesions detected at the study were mural thickening, with adenocarcinoma pathology. MDCT T staging compared to pathological staging was highly significant. Only 33 cases had pathological reports suitable for comparison with the MDCT staging. True positive cases were 30, false positive cases were 2 cases and false negative was only one case, Thus giving sensitivity 96.7% and accuracy 91%. Conclusion: Multidetector CT can play an important role in diagnosis and preoperative staging of gastric cancer.
