Learning objectives
1.
To determine various causes of benign and malignant biliary strictures using MRI and PTC
2.
To demonstrate a diagnostic role of combined CE-MRI,
MRCP,
and PTC in the evaluation of bile ducts in patients with obstructive jaundice,
and the therapeutic role of PTC.
3.
Demonstrate important elements in the assessment and management of benign and malignant biliary stricture
Background
The purpose of this exhibit is to describe imaging characteristics of combined contrast-enhanced MRI,
MRCP,
and PTC to differentiate certain benign and malignant biliary strictures.
Contrast-Enhanced MRI (CE-MRI) and MRCP is a non-invasive diagnostic method to evaluate patients with obstructive jaundice without ionizing radiation.
PTC (percutaneous transhepatic cholangiography) is a more invasive procedure that can be used as both diagnostic and therapeutic tool.
ERCP with tissue biopsy is needed to confirm the diagnosis,
but certain imaging studies can narrow down the differential diagnosis and provide...
Findings and procedure details
A wide spectrum of hepatobiliary and pancreatic diseases can lead to biliary strictures such as primary sclerosis cholangitis,
choledocholithiasis,
pancreatic adenocarcinoma,
and gallbladder carcinoma.
MRI characteristic of malignant features will be reviewed.
MRI protocol and advantages over other modalities will be described.
The role of PCT in visualizing exquisite detail of biliary anatomy and providing opportunities for intervention will be reviewed.
Conclusion
CombinedCE-MRI,and MRCP play an important role incharacterizationof benign and malignant biliary stricture.
These imaging technique helps to narrow differential diagnosis and provide management planning.
Percutaneous biliary interventions play a key role in both diagnosis and treatment of biliary strictures.
