How much radiation is in a myocardial perfusion scan?
Studies from academic institutions performing cardiac MPI with PET imaging have reported radiation exposure ranging from 2.5 to 5 mSv for rest/stress studies.
How much mSv is in a nuclear stress test?
The common radiation-based procedures that heart attack patients undergo — including nuclear stress tests, heart catheterization and, increasingly, CT scans of the heart — typically deliver a radiation dose of between 5 and 15 mSv.
How much radiation is in a nuclear scan?

| Imaging procedures and their approximate effective radiation doses* | ||
|---|---|---|
| Procedure | Average effective dose (mSv) | Range reported in the literature (mSv) |
| CT, cardiac for calcium scoring | 3 | 1.0–12 |
| Nuclear imaging, bone scan | 6.3 | |
| CT, spine | 6 | 1.5–10 |
How much radiation are you exposed to during a nuclear stress test?
Nuclear stress tests involve significant radiation exposure equivalent to 400 chest x-rays.
Is myocardial perfusion imaging safe?
Myocardial perfusion imaging is a noninvasive method for evaluating this blood flow. We also use the scans to look for damage after a heart attack and to determine if previous treatment has helped. While perfusion assessment may reqire you to exercise, the testing process is safe and painless.
How much radiation is in a MIBI heart test?
We have previously shown that the average dose per radionuclide study (excluding myocardial perfusion studies) is 1.5 microSv. Although 5.5 microSv is higher, a technologist is highly unlikely to exceed current dose limits.
How much radiation is a nuclear medicine technologist exposed to?
Estimated radiation exposure for NMTs ranges from 0.2 to 2 μSv/h, depending on whether NMTs are scanning patients (lower dose) or performing injections on patients (higher dose).
How long does lexiscan stay in your body?
The nuclear imaging agent is out of your system within 60 hours, but it is always decaying so it becomes minimal in a relatively short period of time.
How long does the radiation stay in your body after a nuclear stress test?
Self-care: The radioactive liquid will be in your body for 24 to 36 hours after your test.
How long are you radioactive after a nuclear stress test?
The radioactive liquid will be in your body for 24 to 36 hours after your test. You will need to do the following: Drink plenty of liquids as directed.
