PET detected viability in 130 segments that had been defined as non-viable by SPECT. No differences in the analysis by vascular territories were found. Thirty percent of the segments that were defined as non viable by SPECT were viable by PET, meanwhile only 1% of the segments detected viable by SPECT were considered non viable with PET.

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.

Positron emission tomography (PET): is very expensive; uses positron emitting radioisotope (tracer) fluorine-18; gives better contrast and spatial resolution (cf.

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. The discussion will include only a brief introduction into the world of nuclear medicine and the use of single photon emission computed tomography (SPECT) and positron emission tomography (PET). Diagnostic nuclear imaging studies that use radioactive tracers, called Cardiolite® (for SPECT) and rubidium (for PET), to produce images of the heart muscle. When combined with stress, either through exercise or the use of a pharmacological agent, the nuclear scan helps determine if the heart muscle is getting the blood supply it needs. PET/CT In Oncology POSITRON EMISSION TOMOGRAPHY • Nuclear decay produces a positron • Positron travels short distance and annihilates with electron • Annihilation process produces two photons and conserves: - Energy so each photon is 511KeV - Momentum so photons are “ back - to - back ” • Simultaneous detection of the two 511KeV Indeed, the order was fixed (PET after SPECT), with inevitably a difference using a rank test.

Importance: At present, the choice of noninvasive testing for a diagnosis of significant coronary artery disease (CAD) is ambiguous, but nuclear myocardial perfusion imaging with single-photon emission tomography (SPECT) or positron emission tomography (PET) and coronary computed tomography angiography (CCTA) is predominantly used for this purpose.

We explain the primary difference between the two diagnostic tools. Learn what that difference Positron emission tomography (PET) is a functional imaging technique that uses radioactive SPECT is an imaging technique similar to PET that uses radioligands to detect molecules in the body.
