Is a hida scan dangerous?

Not at all: Hida is a very safe study. There are no adverse effects from the radiotracer and you receive less than half the radiation dose you get from a typical ct scan. If they use Kinevac (cck) you may experience abdominal discomfort or nausea, although these effects are more pronounced following rapid infusion which most center don't use these days.

Benefits vs. Risk...: One does receive some radiation dose from a hida scan however usually the test is ordered for a specific reason and the benefits outweigh the risks. The use of cck which is used sometimes during hida could cause some abdominal cramping if used during scan.

Not generally: HIDA scan carries few risks. Risks may include: Allergic reaction to medications containing radioactive tracers used for the scan,bruising at the injection site or rash.
