MRI for liver, biliary, pancreatic, kidneys disorders, MRCP
Pancreas divisum
Pancreas or Pancreatic divisum is a congenital anomaly in the anatomy of the ducts of the pancreas in which a single pancreatic duct is not formed, but rather remains as two distinct dorsal and ventral ducts.
Hypervascular Liver Metastases
Hypervascular Liver Metastases
Pancreatic Cancer
Gadolinium-enhanced 3D LAVA
MRI shows multiple ring enhancing liver lesions.
Hypervasular metastases are best depicted on arterial phase images obtained immediately following IV gadolinium injection.

Lung Cancer
Gadolinium-enhanced 3D LAVA
MRI shows innumerable hypovascular liver metastases.
Hypovascular metastases are best depicted on portal venous phase images.
3D LAVA images provide thin section gadolinium enhanced images with outstanding detail and image sharpness.

MRCP Magnetic Resonance Cholangiopancreatography
When patients have suspected biliary or pancreatic disease, ultrasound imaging is the traditional screening technique. However, ultrasound is limited in its ability to image abnormalities in the biliary and pancreatic ductal systems and further evaluation may be necessary with either endoscopic retrograde cholangiopancreatography (ERCP) or MRCP.
ERCP is a minimally invasive procedure that combines endoscopy with the injection of iodinated contrast agent into the biliary and pancreatic ducts. ERCP has the advantage of combining diagnosis with intervention. In addition, manometry can be performed and the ampulla can be directly visualized. However, ERCP carries a small but significant risk of complications, including pancreatitis, hemorrhage, and perforation. At MGH, the complication rate is 1-2%, significantly lower than the national average. In addition, ERCP may be difficult in patients with post-surgical anastomotic complications.
