Magnetic resonance (MR) cholangio-pancreatography (MRCP) is an established specialist method for imaging the upper abdomen and biliary/pancreatic ducts. Due to limitations of either MR image contrast or low through-plane resolution, patients may require further evaluation with contrast-enhanced computed tomography (CT) images. However, CT fails to offer the high tissue-ductal-vessel contrast-noise ratio available on T2-weighted MRI. MR Super-Resolution Reconstruction (SRR) frameworks can provide high-resolution visualizations from multiple low through-plane resolution single-shot T2-weighted (SST2W) images as currently used during MRCP studies. Here, we investigate the clinical potential of using additional SST2W acquisitions in multiple directions with SRR for higher diagnostic yield.
