Pancreatitis and the role of US, MRCP and ERCP.

Imaging plays a crucial role in the diagnosis of acute and chronic pancreatitis in children. Ultrasound (US) is the primary imaging modality. The US study can be improved by incorporating high resolution imaging, color Doppler, harmonic imaging and panorama view. Computer tomography (CT) is widely used for further evaluation. MR imaging in combination with MR cholangiopancreaticography (MRCP) is emerging as the modality of choice. It is non-invasive and radiation-free. It has high potential to replace endoscopic retrograde cholangiopancreaticography (ERCP), too. The latter is becoming more of an interventional tool. This review discusses the current status and comparative diagnostic potential of US, MRCP and ERCP.
