EVALUATING THE DIAGNOSTIC ACCURACY OF MDCT FOR AMPULLARY AND PERIAMPULLARY TUMORS: A STUDY LINKING HISTOPATHOLOGICAL FINDINGS.

Purpose: Ampullary and periampullary tumors pose challenges in gastrointestinal oncology due to their complex anatomy and malignancy potential. These neoplasms arise in the ampulla of Vater region and surrounding structures, including distal common bile duct, pancreatic head, and duodenum. Early diagnosis is crucial for optimal patient outcomes. Aim: To evaluate MDCT diagnostic efcacy in ampullary and periampullary tumors by correlating imaging with histopathological results. This prospective observational study was conducted on Materials And Methods: patients at Department of Radio diagnosis, Konaseema Institute of Medical Sciences, Amalapuram for CT with clinical suspicion of periampullary tumors. The lesions were correlated with HPE reports. This comparative a Results: nalytical study included 60 patients. A signicant positive correlation existed between benign and malignant tumors distribution with p value < 0.0001. In periampullary tumors, strong correlation exists between HPE diagnosis and CT results. MD Conclusion: CT is a promising imaging technique for periampullary tumor assessment.
