What are the differences between frcp and mrcp?

Ercp vs mrcp. ercp is an special endoscopy to look at the bile ducts of the liver (it is a procedure) and potentially manipulate and treat any disease there. mrcp is an MRI (imaging study from radiology) to look at the bile ducts.
Fluoroscopy vs MRI. I am assuming frcp and ERCP are the same. These stand for fluoroscopic/endoscopic retrograde cholangiopancreatography and allow for the evaluation of the pancreatic and common bile ducts. If necessary a stent can be placed during this procedure, biopsy perfromed or stones removed. Mrcp is the MRI equivalent and allows for diagnosis of ductal abnormalities without the ability to treat.
