Multimodality Imaging in Obstructive Jaundice: A Review with Our Experience
Dr. Ankit Kumar Yadav
Abstract: A brief review of the different imaging modalities in obstructive jaundice are discussed here. Ultrasound serves as a preliminary investigation in comparison to other non-invasive imaging modalities like MRCP and CECT (contrast-enhanced computed tomography). Ultrasound remains one of the easily available preliminary imaging modalities in obstructive jaundice. However limitations due to inability to tell the exact extent of the lesion and the inability to detect small stones in the distal CBD exist, which are overcome in MRCP (Magnetic Resonance Cholangiopancreatography). MRCP with its higher diagnostic accuracy, is another upcoming non-invasive modality which will answer most of our questions in the clinical setting of obstructive jaundice. In a study conducted in our hospital with 140 cases of clinical obstructive jaundice, it was found that the sensitivity of detecting the presence and level of obstruction was almost same 100% vs 98% and 98% vs 99% respectively. But it was found that with respect to the extent and cause of obstruction ultrasound was not as sensitive (67% vs 94%) and specific (68% vs 89%) as compared with CECT and MRCP. Additionally, MRCP with MRI helped detect the presence of small metastases missed by ultrasound and CECT. Ultrasonography though easily available preliminary imaging modality in obstructive jaundice is often not able to diagnose the exact cause and extent of lesion whereby more advanced imaging modality like CECT and MRCP plays an important role to accurately diagnose the exact cause and extent of the underlying lesion expediting accurate diagnosis and further aiding in patient management.
