The radiotracer decays speedily and is particularly productive For less than a brief time. Hence, it is important for you to be in time for the appointment and also to acquire the radioactive material within the scheduled time. Late arrival for an appointment could call for you to reschedule the procedure.
Thus, purposeful imaging attained by PET, which depicts the spatial distribution of metabolic or biochemical activity in the body might be a lot more specifically aligned or correlated with anatomic imaging obtained by CT scanning. Two- and 3-dimensional picture reconstruction can be rendered as being a perform of a common program and Command process.[one]
PET scans have to be interpreted carefully for the reason that noncancerous ailments can appear to be cancer. Also, some cancers do not appear on PET scans. Quite a few sorts of good tumors is often detected by PET-CT and PET-MRI scans, including:
Parts of bigger depth are known as “hot spots.” These may clearly show large concentrations of the radiotracer and where by there is a high level of chemical or metabolic action. Much less rigorous locations, or “cold places,” suggest a more compact concentration of radiotracer and less exercise.

Compared with other imaging methods, PET scans deal with processes and molecular action inside your body. This offers them the likely to locate ailment in its earliest phases.
