PET’s diagnostic accuracy was higher than SPECT’s (89% versus 79%) and was higher in all populations, including the obese patients. Furthermore, the researchers demonstrated that image quality was excellent in 78% of PET scans compared to 62% of SPECT studies. 20 The benefits of PET, however, must be balanced by the financial pressures of modern healthcare systems and the need for fiscal Se hela listan på diffen.com Your doctor has requested a PET Myocardial Perfusion (MP) Stress Test, also called a Rubidium PET. This procedure evaluates the blood flow (perfusion) through the coronary arteries to the heart muscle using a radioactive tracer. Whereas PET and SPECT rely on similar principles to produce their images, important differences in instrumentation, radiochemistry, and experimental applications are dictated by inherent differences in their respective physics of photon emission. See schematic figures below for each principle.

There are several differences between SPECT and PET to be noted. In general, the severity of hypometabolism seen on PET is greater than the severity of hypoperfusion on SPECT. The nuclear societies data support increased accuracy of PET over SPECT, particularly for heavier patients, where breast, chest wall, and diaphragmatic attenuation interfere with conventional SPECT. Patients who need PET because SPECT is not sufficient for their clinical presentations are individuals who: have suspected multi-vessel balanced or diffuse CAD, are morbidly obese (BMI > 40 It is not the intent of this book to present an in-depth explanation of nuclear medicine technology.

SPECT scans measure gamma rays, and the radiotracers used with PET scans produce small particles called positrons. The detectors in the PET scanner measure these photos to create images of internal organs. PET Scan Images are Clearer. PET scan images are generally reported to offer a higher resolution of 5 to 7 mm, compared with a cardiac SPECT scan resolution of 12 to 15 mm. Pros and Cons. SPECT has a wider range of circulation than PET which also makes it more affordable with an average cost of $500,000.
