The radioactive tracer used during nuclear heart scanning exposes the body to a very small amount of radiation. No long-term effects have been reported from these doses.
Radiation dose might be a concern for people who need multiple scans. However, advances in hardware and software may greatly reduce the radiation dose people receive.
Some people are allergic to the radioactive tracer, but this is rare.
If you're pregnant, tell your doctor or technician before the scan. It might be postponed until after the pregnancy.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Nuclear Heart Scan, visit www.clinicaltrials.gov.
