I took first part of hida scan and they would not continue it. what could reason be?

Depends: Usually, a hida scan as 2 parts. The first images the anatomy and sees if all of the tubes connecting the liver, gallbladder and small bowel are open. If they are and the gallbladder fills up, the second part of the scan is done, giving a medicine to cause the gallbladder to empty (measuring ejection fraction). If all of the anatomy is not seen, the second part usually cannot be done.

Positive test.: Most likely either the gallbladder or small bowel were not demonstrated. This indicates either an obstructed cystic duct or common bile duct.

Many possibilities : There could be many reasons to not continue. 1) there could be a technical problem with the camera or radiopharmaceutical. 2)the dr could call and say they dont need the study anymore. 3) they found the answer to your problem 4)sometimes the patient says they dont want to continue these are a few of the most common.R.

Depends.: If non visualization of gall bladder can not do ejection fraction. Non visualization may mean cystic duct obstruction or in some circumstances acute cholecystits.If evidence of significant biliary obstruction many clinicians will not administer CCK to produce gb contraction. You should consult physician ordering or performing test.
