SPECT (Single Photon Emission Computed Tomography) uses radioactive tracers that are generally easier to obtain and have longer half-lives compared to the positron-emitting tracers used in PET (Positron Emission Tomography). This makes SPECT more accessible and practical in some clinical settings. Both SPECT and PET are noninvasive and can monitor brain activity, but the tracers' availability is a key difference.
