Role of Multi-Detector Computed Tomography (MDCT) in Assessment of Biliary Neoplasms

Abstract Background Biliary neoplasms are commonly encountered in the day-to-day radiological practice and can be benign or malignant. Multidetector CT (MDCT) is a noninvasive imaging modality for evaluation of patients with biliary obstruction, to localize the cause of obstruction, detect the presence of mass lesion, and define its extension and identify remote metastasis. Objective To find out the role of MDCT scan in the evaluation of biliary neoplasms with respect to nature, cause and level of obstruction. Methods During the period from January 2022 to August 2022, the present study included 30 patients with clinically suspected biliary obstruction and previously radiological or laboratory diagnosed cases of biliary malignancy after fulfilling the inclusion and exclusion criteria and taking written /verbal informed consent. 16 patients were males and 14 were females, their ages ranged between 36– 85 years with mean age of 64years old. Results The mean age of participants was 63.73±11.11 years old; and slight male predominance (53.3%). in correlation to histopathological findings, MDCT was 95.2% sensitive in detection of cholangiocarcinoma (20/21*100). It was 100% sensitive in detection of combined cholangiocarcinoma 0.0001) Conclusion Multidetector computed tomography MDCT can be considered a noninvasive fast with high sensitivity imaging tool in the assessment of patients with biliary neoplasms. The MDCT is satisfactory for staging of biliary neoplasms and for accurate preoperative assessment of the tumor extent.
