Question 1

what is a hida scan and an mrcp test?

Accepted Answer

Liver tests: A hida scan is a scan where a medicine that is taken up and excreted by you liver is tagged with a radioactive particle that can be captured on a monitor. It measures if you havea bile blockage or leak. An mrcp is an MRI that looks at your bile and pancreatic ducts. It is a noninvasive way to avoid a endoscopic  retrograde cholangiopancreatogram (ercp).

Question 2

in diagosing pancreatitis, which is more useful, mri or ct? and are regular abodominal mri and ct different from mrcp or hida scan?

Accepted Answer

Each has its place: CT is the standard study for demonstrating pancreatitis but usually it can be diagnosed by blood test and clinical exam. CT is usually reserved for looking for complications. It's faster &amp; cheaper than MRI or HIDA. MRI &amp; HIDA are used to look for causes of pancreatitis, like obstructed ducts. Most cases of pancreatitis require only simple ultrasound to rule out obstruction, and no other studies.

Question 3

5wks ago i passed out ruq pain under rib going into back. have duodenitis. ct mrcp norm amylase was 137 then 97 now 154 hida scan40% extraction? help

Accepted Answer

Duodenitis: Duodenitis is inflammation occurring in the duodenum, may result in abdominal pain, bleeding, and other gastrointestinal symptoms.The most common cause of duodenitis is a stomach infection associated with bacteria  helicobacter pylori (h pylori). This can be treated with antibiotics.Most accurate sign of pancreatitis would be elevated lipase level. 40% gall bladder ef is usually normal level.

Question 4

to colin kopes-kerr: i have had mrcp, ct abd/pel (3) abd us, endoscopy, colonoscopy, hida scan, chest x-rays, ekg! norm but still have upper abd pain:(?

Accepted Answer

Abdominal pain: Is the pain after eating?  Has it responded to any medications? Are any of your blood tests abnormal?  Liver function tests done?  During the hida scan, did they calculate your gallbladder ejection fraction?  Perhaps you ought to consider a second opinion.

Question 5

open surgery to remove gallstones 4mths ago. i still have my gb.since then ive had urq pain radiating to my back once i eat any fat. normal blood work.ultras 4 mm stone or sludge normal ct. what do next. mrcp or hida?

Accepted Answer

: Not knowing the details it is surprising that gall bladder was not removed . It is best you consult a competent surgeon or gasr/ent. for precise procedure.

Question 6

4mos of  upper rt quad acute spasms under rt breast, ribs , back, mrcp & sono w/ dilated  9cm  bile duct , lab work neg/no stones.  if hida scan  neg ?

Accepted Answer

Depends: I assume you mean 9 mm cbd not 9 cm. The hida seems a bit unnecessary at this point. If you have a dilated duct and normal liver tests, its prob not obstructed. If any further workup is performed, i'd go with an ercp.

Question 7

normal mrcp except for little sludge in gallbladder neck. no biliary ductal dilatation. hida showed no sign of cystic duct obstruction. why would hida show prompt tracer filling of my liver and gb but bowel not seen after 90 minutes? no cck given?

Accepted Answer

: Ask this question of the gastroenterologist who ordered the study. Good Luck

Question 8

ct/mrcp shows inflammation of gallbladder,liver and spleen. sev ruq pain. 18yo. ana positive,igg low, no stones. dr ordered hida scan. ideas?

Accepted Answer

See rheumatologist: You appear to have an autoimmune and/or immune deficiency problem. I note that you are already on Plaquenil (hydroxychloroquine) (SLE?). If you are already under the care of a rheumatologist, consider getting an immune evaluation as well because of the low IgG (how low?).  If the problem progresses, you need to go to an university center for further workup.

Question 9

gallbladder surgery 3/6 due to 15% hida/ruq pain. during gallbladder attacks alt and ast rising (normal prior).now sit at alt 245/ast 173 (25 days post op). normal alk phos and bilirubin. us/ct/mrcp all normal. autoimmune hepatitis or due to surgery?

Accepted Answer

: It would be helpful to know the trend your ALT and AST-are the numbers increasing, decreasing or staying the same? If the numbers are decreasing, it may be related to your gallbladder disease and the numbers should be followed until they normalize. But, if the numbers are continuing to rise, then you need to see a GI doctor for further evaluation. You may need more testing so see a GI doctor.

Question 10

can hida scans show false positives?

Accepted Answer

Absence of the : Isotope in the gallbladder can be seen in settings other than acute cholecystitis. Chronic cholecystitis, patients on intravenous hyperalimentation, and inadequate fasting before the procedure are a few causes.
