Quantitative magnetic resonance cholangiopancreatography (QMRCP), including data preparation and transmission, interpretation and report, obtained with diagnostic magnetic resonance imaging (MRI) examination of the same anatomy (eg, organ, gland, tissue, target structure) (List separately in addition to code for primary procedure)

Quantitative magnetic resonance cholangiopancreatography (QMRCP) is an advanced imaging technique that enhances the standard magnetic resonance cholangiopancreatography (MRCP) procedure. MRCP itself is a specialized form of magnetic resonance imaging (MRI) that captures detailed three-dimensional images of the pancreas, gallbladder, liver, and bile ducts without the need for invasive procedures. This noninvasive approach utilizes a powerful magnetic field, radiofrequency pulses, and sophisticated computer algorithms to generate high-resolution images of the biliary and pancreatic anatomy. The primary purpose of MRCP is to evaluate conditions such as pancreatitis and to identify potential abnormalities, including tumors, gallstones, inflammation, or infections within the biliary tract. QMRCP builds upon the foundational MRCP by incorporating additional software that provides quantitative analysis of the acquired 3D images. This software generates volumetric measurements of the entire biliary tree and assesses the diameter of the ducts, offering critical metrics that aid in the characterization of biliary duct abnormalities, such as strictures and dilations. These quantitative assessments are particularly valuable in differentiating primary sclerosing cholangitis from other hepatic inflammatory diseases prior to treatment and in monitoring for the development of cholangiocarcinoma. The QMRCP process requires an operator who is specifically trained in the use of the software to effectively process the MRCP images, enhance the visualization of the biliary ducts, segment the gallbladder, and accurately model the biliary tree. It is important to note that QMRCP is reported separately in addition to the primary procedure code for an abdominal MRI when performed concurrently on the target organ.
