PET scans provide quantitative information at a cellular level and as such are beneficial in a range of oncologic instances â including the assessment of cancer, how it metabolises, whether it has spread in the body and how a tumour might be responding to treatment. Prior to a PET scan, the patient receives an injection of a substance that contains a type of sugar attached to a radioactive isotope. “The Ga-68 PET/CT scan is a tool for the care of low or intermediate grade neuroendocrine tumors, primarily for making treatment decisions with early detection of small lesions that impact treatment plans,” said Renuka Iyer, MD, Co-Director of the Liver and Pancreas Tumor Center at Roswell Park Comprehensive Cancer Center, Buffalo, NY. How does a PET scan work? Often, you start with an X-ray because itâs a quick way to get basic information. PET scans. Before the scan, you will be injected with a liquid that contains small radioactive particles. Cancer cells) will shine brighter because theyâre more metabolically active. Nuclear medicine imaging uses small amounts of radioactive material to diagnose, evaluate or treat a variety of diseases. Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.Different tracers are used for various imaging purposes, depending on the target process within the body. These scans are often used to detect cancerous growths and to evaluate how effective a patient’s cancer treatment is. In this recent trial, 62 patients who had previously undergone abdominal surgery as part of their treatment were referred for PET/CT scanning for evaluation of pelvic recurrences. While CT scans, MRIs and X-rays can detect changes in shape or mass, PET scans can detect actual physiological changes in the tissues and organs. Thus, CT scans reveal the gross features of the brain but do not resolve its structure well. Access your health information from any device with MyHealth.
