Frequently Asked Questions

QWhat exactly is nuclear medicine?

Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive materials, or radiopharmaceuticals, to diagnose and treat various conditions. These materials help doctors see how your body is functioning, pinpointing issues at a cellular level.

QHow safe is nuclear medicine?

Generally, nuclear medicine is quite safe. The amount of radiation you're exposed to is typically low, similar to that of a conventional X-ray or CT scan. Plus, radiopharmaceuticals are designed to target specific areas, minimizing exposure to the rest of your body.

QCan kids undergo nuclear medicine procedures?

Yes, kids can undergo these procedures. Pediatric doses are carefully calculated to ensure they're as low as possible while still providing accurate results. Safety and effectiveness are top priorities when it comes to children.

QHow long does a nuclear medicine test take?

Duration varies depending on the test. Some scans take only about 20 minutes, while others might require several hours or even multiple visits to complete. Your doctor will give you a heads-up about what to expect.

QWhat should I do to prepare for a nuclear medicine procedure?

Preparation depends on the specific test. You might need to fast for a few hours, avoid certain medications, or drink plenty of water. Always follow the instructions provided by your healthcare provider or the nuclear medicine department.

QWill I feel any side effects from the radiopharmaceuticals?

Most people don't experience side effects from the radiopharmaceuticals used in nuclear medicine. If side effects do occur, they're usually mild and short-lived. Your healthcare team is there to ensure your comfort throughout the process.

QHow long will the radioactive material stay in my body?

The radioactive material's half-life—the time it takes for half of the substance to leave your body—varies. Most of it is gone within a few hours or days, expelled naturally through your urine or stool. Your doctor can provide more specific information based on the radiopharmaceutical used.

QCan I go about my day normally after a nuclear medicine test?

Yes, in most cases, you can resume your usual activities right after your test. However, you might be advised to avoid close contact with pregnant women and young children for a short period, just as a precaution. Drinking lots of water to help flush the radioactive material from your body is often recommended too.
