PET/CT

Where Compassion Meets Expertise in Cardiology Care

PET/CT scanning, short for Positron Emission Tomography/Computed Tomography, is a medical imaging technique that combines two powerful imaging modalities: PET and CT.

​

PET Imaging: Positron Emission Tomography (PET) involves the use of small amounts of radioactive materials, known as radiotracers, to visualize and measure metabolic processes in the body. These radiotracers are typically molecules labeled with a radioactive isotope, such as F-18 fluorodeoxyglucose (FDG), which is similar to glucose. Cancer cells and other diseased tissues often have higher metabolic activity and absorb more of these radiotracers, making them visible on PET scans.

​

CT Imaging: Computed Tomography (CT) utilizes X-rays to create detailed cross-sectional images of the body.  It provides excellent anatomical information, showing the structure and density of tissues, organs, and bones.

Combined PET/CT: In PET/CT scanning, the PET and CT scans are performed sequentially during the same imaging session using a single machine.  

 

This allows for the fusion of metabolic information from the PET scan with anatomical details from the CT scan, resulting in more comprehensive and accurate diagnostic information.  By overlaying the two sets of images, doctors can precisely locate areas of abnormal metabolic activity within the context of the body's anatomy.

Benefits:

  1. Improved Diagnosis:  The combination of metabolic and anatomical information enhances the accuracy of diagnosis, particularly in detecting cancer, evaluating heart disease, neurological disorders, and assessing treatment response.

  2. Single Procedure:  Patients undergo both PET and CT scans in a single session, reducing the need for separate appointments and streamlining the diagnostic process.

  3. Precise Localization:  PET/CT enables the precise localization of abnormal metabolic activity, aiding in treatment planning and guiding interventions such as biopsies or surgery.

  4. Efficient Workflow:  By acquiring both sets of images simultaneously, PET/CT scanning offers efficient workflow for healthcare providers and minimizes the time required for imaging.

​

Overall, PET/CT scanning plays a crucial role in the diagnosis, staging, and monitoring of various diseases, providing valuable information to guide patient management and treatment decisions.
