PET and the Heart

How do PET scans differ from other tests?

Clinical studies have shown that PET scans are more accurate than other widely used tests such as ECG (electrocardiogram), stress testing and SPECT (single photon emission computed tomography). These tests are associated with "false positive" and "false negative" results. False positives are results that show coronary heart disease where none really exists. False positives can lead to people undergoing unnecessary procedures. Because PET scans are so accurate, they are often used to confirm other tests if a false positive or false negative is suspected. "False negatives" are normal results when coronary heart disease really exists. False negatives can lead to undetected heart disease.
