EUS

EUS = endoscopic ultrasound.

Advantage of EUS over CT scan is that you can do biopsy while CT scan or MRI, you may not be able to do biopsy.

Note: may be ordered to further evaluate nodules, even nodules that are discovered to be benign during EGD because it may be just surface scraping but not addressing the whole nodule.

abd pain, w/ possible ductal dilation

STAT MRCP
if negative, STAT HIDA scan

If you do an ultrasound, and you see a stone => done!
But you don't see a stone, then HIDA scan helps detect cholecystitis

Ductal dilation: dilation of the pancreatic duct
Dx of ductal dilation: ultrasound
Cause of ductal dilation: http://radiopaedia.org/articles/bile-duct-dilatation-differential

MRCP is an MRI shows soft tissues, biliary tract system, pancreatic system.
HIDA scan is radioactive tracer to track bile flow.

HIDA Scan

HIDA scan is to see bile flow. So, if u think pt may have cholescystitis but there's no stone shown by Ultrasound, then if you do HIDA scan, you'll see if gallbladder is blocked. It doesn't tell you why it's blocked, but it tells you if it's blocked (obstruction)  ~from my bf

A hepatobiliary (HIDA) scan is an imaging procedure used to diagnose problems of the liver, gallbladder and bile ducts.

For a HIDA scan, also known as cholescintigraphy and hepatobiliary scintigraphy, a radioactive tracer is injected into a vein in your arm. The tracer travels through your bloodstream to your liver, where the bile-producing cells take it up. The tracer then travels with the bile into your gallbladder and through your bile ducts to your small intestine.

A nuclear medicine scanner (gamma camera) tracks the flow of the tracer from your liver into your gallbladder and small intestine and creates computer images.
