WebA similar technique is single-photon emission computed tomography (SPECT). For SPECT imaging, different isotopes are used (eg, 99m Tc, 131 I, 123 I, 111 In). The sensitivity of SPECT is less than PET, but SPECT can visualize different radioisotopes at the same time, because different isotopes emit different γ-rays of different energies in SPECT.

Hybrid Imaging: SPECT/CT and PET/CT Radiology Key

WebFor example, if your doctor is looking at a tumor, he or she might use radiolabled glucose (FDG) and watch how it is metabolized by the tumor. The test differs from a PET scan in that the tracer stays in your blood stream rather than being absorbed by surrounding tissues, thereby limiting the images to areas where blood flows. Webseen, for example, in the case of cardiac PET vs. SPECT. Coronary perfusion and myocardial viability are most commonly performed with SPECT. While SPECT has many applications in neurology and oncology, the majority of SPECTscans are performed in the field of cardiology. SPECT is now a cornerstone with any patient with heart disease.
