The scan typically takes 20-30 minutes. With preparation and post-scan observation, the entire process may take around an hour.

The scan itself is painless. However, patients may feel a warm sensation or metallic taste in the mouth when the contrast dye is injected, which is temporary.

There is a low radiation exposure, which is generally safe for most patients. The contrast dye, while safe, may pose minor risks like allergic reactions or kidney effects in susceptible patients. It’s important to inform your doctor if you have allergies or kidney problems.

Fasting for a few hours before the scan is usually recommended if contrast dye is used. Remove metal objects near the thigh area, and follow any additional instructions from your healthcare provider.
