    Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.

    Complete body PET-CT fusion image Brain PET-MRI fusion image. PET scans are increasingly read alongside CT or MRI scans, with the combination (co-registration) giving both anatomic and metabolic information (i.e., what the structure is, and what it is doing biochemically). Because PET imaging is most useful in combination with anatomical ...

    SPECT scans are significantly less expensive than PET scans, in part because they are able to use longer-lived and more easily obtained radioisotopes than PET. Because SPECT acquisition is very similar to planar gamma camera imaging, the same radiopharmaceuticals may be used. If a patient is examined in another type of nuclear medicine scan ...

  8. PET-MRI - Wikipedia

    en.wikipedia.org/wiki/PET-MRI

    PET-MRI systems don't offer a direct way to obtain attenuation maps, unlike stand-alone PET or PET-CT systems. [32] [33] Stand alone PET systems' attenuation correction (AC) is based on a transmission scan (mu - map) acquired using a 68 Ge (Germanium-68) rotating rod source, which directly measures photon attenuation at 511 keV.
