Frequently Asked Questions
A PET-CT scan is a sophisticated medical imaging method that merges positron emission tomography (PET) and computed tomography (CT) scans to produce detailed images of the body's internal structures and metabolic functions.
During a PET-CT scan, a small dose of radioactive tracer is injected into the bloodstream. This tracer gathers in areas with high metabolic activity, such as tumors. The PET scanner captures the emitted radiation, while the CT scanner generates precise anatomical images.
PET-CT scans are invaluable for diagnosing and monitoring a wide array of medical conditions, including cancer, neurological disorders, and heart diseases. They offer detailed insights into the location, size, and metabolic activity of abnormalities.
PET-CT scans are employed for diagnosing and tracking various conditions like cancer, Alzheimer's disease, epilepsy, brain tumors, and heart-related issues.
Yes, PET-CT scans are considered safe with minimal radiation exposure, posing no significant risk to patients.
Typically, a PET-CT scan lasts between 30 to 60 minutes, depending on the complexity of the procedure.
Patients may need to fast for several hours before the scan and disclose any medical conditions or medications to their healthcare provider.
While PET-CT scans are generally safe, there's a minimal risk of allergic reactions to the tracer or radiation exposure effects, though these occurrences are rare.
PET-CT scans are highly accurate, providing precise details about abnormalities' location, size, and metabolic activity.
Yes, PET-CT scans are widely used for cancer detection and staging due to their ability to identify cancerous cells based on increased metabolic activity.
