A Radiologist explains the role of PET-CT in molecular imaging.
Irving, TX – June 15, 2020 –PET-CT is a nuclear imaging technique that combines positron emission tomography with computed tomography (CT). The technique allows doctors to visualize the metabolic activities of body cells. It uses a radiotracer to find cancer. Molecular imaging provides detailed images of the molecular and cellular activity in the body to enable doctors to personalize patient care.
“PET-CT is an innovative imaging technique that helps to evaluate and manage care for cancer patients,” explained the radiologist. “The technique provides detailed information that doctors can use to assess disease progression, plan treatment for individual cancer patients, and monitor their progress.”
PET-CT detects all the cellular changes occurring early in the course of cancer. It uses an imaging agent (radiotracer) to monitor cellular activity. When the agent travels through the body, it accumulates in a target location and attaches itself to specific cells. A computer will create pictures that will be used by physicians to discern if the tissues and organs are functioning well.
Physicians use PET-CT to;
- Diagnose and stage cancer – Doctors use PET-CT to determine the location of a tumor and its stage and whether it has spread to other body parts.
- Plan patient treatment – Doctors can select the most effective treatment based on the molecular properties of the disease and the genetic makeup of the patient.
- Evaluate if treatment is effective – Doctors will use the results from a PET-CT scan to determine a patient’s response to particular drugs and ongoing treatment. They’ll also be able to alter treatment plans base on the changes in cellular activity seen on PET-CT images.
- Manage treatment– PET-CT can be used to monitor patients and detect any early recurrence.
“PET-CT imaging is effective in eliminating the need for other tests such as biopsies,” continued the radiologist. “The technique can detect whether lesions are malignant or benign, so there’ll be no other tests required to confirm the diagnosis.”
