Positron Emission Tomography (PET) and Computerized Tomography (CT) are each customary imaging instruments that permit physicians to pinpoint the placement of most cancers within the physique before making remedy suggestions. This allows docs to treat these diseases earlier and more precisely. These areas of disease will present up as brilliant spots on the PET scan. PET can show abnormalities that other imaging techniques might not detect, leading to early and more accurate analysis, applicable treatment, and closer monitoring.
Nevertheless, nuclear medication scans are extra delicate than different methods for a wide range of indications, and the useful information gained from nuclear medicine exams is usually unobtainable by different imaging methods. A PET scan (positron emission tomography scan) screens the biochemical functioning of cells by detecting how they course of certain compounds, corresponding to glucose (sugar).
PET scans reveal areas of decreased blood move in the coronary heart. When both of these scans is carried out along with a PET scan, they result in what’s called picture fusion. In addition they may be used if your physician suspects recurrence of a earlier breast cancer.
If any special instructions are crucial, you may be informed by a technologist, nurse or physician before you leave the nuclear medication division. A PET scan can typically detect these very early modifications, whereas a CT or MRI detect adjustments slightly later, because the disease begins to trigger modifications in the structure of organs or tissues.
