An ISO scan, in the context of the provided information, refers to a highly sensitive PET/CT scan that images the biology of disorders at the molecular level while simultaneously providing a detailed picture of the body's internal anatomy. The combination of PET and CT scans in a single scan offers the strengths of both imaging modalities.
Here's a breakdown:
-
PET Scan (Positron Emission Tomography): This imaging technique focuses on the biology of tissues and organs. It uses radioactive tracers to detect changes at the molecular level, often identifying diseases before they are visible on other imaging tests. This allows doctors to see how well organs and tissues are working.
-
CT Scan (Computed Tomography): This imaging technique provides a detailed anatomical picture of the body's internal structures. CT scans use X-rays to create cross-sectional images, showing bones, organs, and soft tissues with great clarity.
-
PET/CT Scan Combination: The ISO scan, as a PET/CT scan, combines the functional information from the PET scan with the detailed anatomical information from the CT scan. This allows physicians to precisely locate areas of abnormal biological activity and understand their relationship to surrounding anatomical structures.
In simpler terms, imagine a GPS system. The PET scan tells you where there is activity (like a potential problem area), and the CT scan provides a detailed map of the surrounding area, showing exactly what that activity is near (like which organ or tissue). Combining these two provides a more complete and accurate picture for diagnosis and treatment planning.
