What quadrant of the abdomen are the liver and gallbladder found?
What is the right upper quadrant?
How long after radiopharmaceutical injection should you begin imaging for a routine hepatobillary scan?
What is immediately?
What hormone does Sincalide mimic?
What is CCK?
What is the fasting status required for patients?
Patients need to be fasted for 2-6 before the scan takes place.
What cells are responsible for bile production in the liver?
What are hepatocytes?
In a normal hepatobiliary scan, which of the following structures will not be visualized?
What is the spleen?
What is the adult dose of Tc99m-Mebrofenin?
What is 3-5 mCi?
What is the patient positioning for injection and acquisition?
What is Supine for both, with liver in the upper left corner in the FOV.
What is responsible for regulating bile and pancreatic juice flow with phasic contractions?
What is the sphincter of Oddi?
If the gallbladder, common bile duct, and duodenum are not visualized after an hour of injecting the radiopharmaceutical, delayed imaging CAN be performed at what time point?
What is 4 hours?
What is the method of localization for Choletec?
What is active transport by hepatocytes?
List the contraindications that need to be considered before proceeding with a HIDA scan.
- The 3 normal
- Morphine intolerance or allergy
- Respiratory depression in non-ventilated patients
Bile drains from the right and left hepatic ducts directly into the:
What is the common hepatic duct?
What position is the active detector in for a hepatobiliary scan?
What is anterior?
After imaging for 60 mins (or less), we are able to visualized the liver and small bowel. No gallbladder is seen, what medication can be given and why?
What is morphine? It will cause the sphincter of Oddi to contract, increasing pressure in the bile ducts and pushes bile into the gallbladder.
How long before the exam do pts need to withhold pain medications that contain opioids?
What is 4-6 hours?
What is the primary hormone needed for proper functioning of the gallbladder?
What is CCK?
How long does it take for the small bowel to be visualized in a normal result?
What is 10-60 minutes?
What is the normal biodistribution of Tc99m-Mebrofenin?
What is Heart, Liver, Gallbladder, and small bowel?
Describe a circumstance when pre-treatment with sincalide may be necessary.
If a patient has fasted longer than recommended or for more than 24 hours we will need to pre-treat them with sincalide to stimulate the gallbladder to empty before the exam.
