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 ...

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 ...
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.
In some centers, the nuclear medicine scans can be superimposed, using software or hybrid cameras, on images from modalities such as CT or MRI to highlight the part of the body in which the radiopharmaceutical is concentrated. This practice is often referred to as image fusion or co-registration, for example SPECT/CT and PET/CT.
PET scanning is also used for diagnosis of brain disease, most notably because brain tumors, strokes, and neurondegenerative diseases (such as Alzheimer's disease and Parkinson's disease) all cause great changes in brain metabolism, which in turn causes detectable changes in PET scans. PET is probably most useful in early cases of certain ...
PET is often conducted by having the person consume a drink that includes radioactive isotopes or by having the isotopes injected into a person's bloodstream. These isotopes are absorbed by different tissues in the body, including malignant tumour cells, and PET imaging can visualize the function or detect tumour cells by visualizing how the ...
After the scan is complete, the patient is encouraged to eat and drink normally, with special attention to plenty of fluids. The barium sulfate is excreted through defecation , so extra fluid intake helps prevent constipation , which is a possible side effect (see Johns Hopkins Medicine Health Library for an example of a possible patient ...
