PET-CT stands for Positron Emission Tomography-Computed Tomography. It’s a medical imaging technique that combines PET and CT scans into a single examination.
PET uses a radioactive tracer to detect chemical activity in the body, such as glucose metabolism. It’s particularly useful in diagnosing cancers, heart disease, and brain disorders because these conditions often involve increased metabolic activity.
CT (Computed Tomography) uses X-rays to create detailed cross-sectional images of the body. It provides information about the body’s anatomy, such as the size, shape, and location of organs and tissues.
Combining PET and CT scans allows for a more comprehensive assessment of both metabolic activity and anatomical structures. It helps doctors better localize abnormalities and distinguish between benign and malignant lesions. PET-CT is commonly used in oncology for cancer staging, treatment planning, and monitoring response to therapy.
Who performs PET-CT scans?
A PET-CT scan will be performed by a technologist who specializes in these types of scans. After the completion of your scan, a doctor specializing in nuclear medicine or radiology will analyze the test results and interpret the findings. You can have the PET-CT scan performed at a hospital or an imaging test center.
