Abstract
Introduction: A recent method of MDCT reconstruction with Mini? and was introduced for visualization of biliary structures. This technique depends on the hypodense content of dilated bile ducts as negative contrast agent for differentiation from the surrounding tissues.
Aim of the Work: The purpose of thjs study is to assess the value of Minn" reconstruction of 64-channel MDCT as compared to that of average intensity projections images in evaluation of cases of obstructive jaundice.
Patients and Methods: The current study was performed between September 2012 and October 2014 on 30 patients with clinical, biochemical and imaging evidences of biliary tract obstruction referred to the Radiology Department in Kasr Al-Aini University Hospital from the Departments of Tropical Medicine, Internal Medicine and Surgical Units.
Results: Mini? reconstruction images of MDCT were considered satisfactory for diagnosis of causes of biliary obstruction in 90% with no need for average intensity projections images. Further need of axial average intensity projections source images was needed in 10% of cases with malignant obstruction for more evaluation of mass extension and staging.
Conclusion: In our study, we concluded that MiniP reconstruction images of MDCT are both feasible (as regarding the reconstruction time, the duration of reviewing as well as the number of images to be documented on film) and of great value in the assessment of cases of biliary obstruction comparable to average intensity source images which make it accepted in routine practice.
