  2. 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.

  3. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.

  4. Theranostics - Wikipedia

    en.wikipedia.org/wiki/Theranostics

    Imaging techniques, such as PET and MRI, can provide valuable information about the tumor microenvironment, immune cell dynamics, and response to immunotherapies. Furthermore, theranostic strategies involving the use of radiolabeled immunotherapeutic agents allow for simultaneous imaging and therapy, aiding in patient selection, treatment ...

  6. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    PET images can be viewed in comparison to computed tomography scans to determine an anatomic correlate. Modern scanners may integrate PET, allowing PET-CT, or PET-MRI to optimize the image reconstruction involved with positron imaging. This is performed on the same equipment without physically moving the patient off of the gantry.

    Prior to a single piflufolastat (18 F) PET/CT scan, all of these participants had baseline conventional imaging performed that did not show definite spread of prostate cancer. [4] Piflufolastat (18 F) PET detected at least one positive lesion in at least one body region (bone, prostate bed, pelvic lymph node, other lymph nodes, or soft tissue ...
