What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• Fast or irregular heart rhythms.
• Long-acting nitrate medicines and digoxin.
• Recent nuclear scans, such as thyroid or bone scans.
• Barium, such as from a barium enema, and bismuth, such as Pepto-Bismol.
• Inability to remain still during the test. You may not be able to have the test if you have severe back problems or other physical disabilities that prevent you from lying flat.
• Obesity.
• Pregnancy. Cardiac blood pool imaging is not usually done during pregnancy because the radiation could damage a developing fetus.
