PET CT scan | Helios Clinic Berlin-Buch, Germany

Positron Emission Tomography-Computed Tomography, commonly known as PET-CT, is a sophisticated medical imaging technique that combines two powerful technologies to provide detailed insights into the structure and function of organs and tissues within the body. This imaging modality plays a crucial role in diagnosing, staging, and monitoring various medical conditions, particularly cancer. We offer to perform the scan in our nuclear medical unit with the proper interpretation and further recommendations. A PET-CT scan involves using a small amount of radioactive material called a radiotracer injected into the patient's body. This radiotracer emits positrons, which are particles that interact with nearby electrons, leading to the production of gamma rays. These gamma rays are then detected by a PET scanner, creating detailed images of the metabolic activity within the body. Adding a CT scan further enhances the precision of the images by providing anatomical details. The procedure begins with injecting the radiotracer into a vein, usually in the arm. Patients may experience a slight sensation at the injection site, but this discomfort is brief. Following the injection, there is a waiting period during which the radiotracer circulates through the body and is absorbed by the targeted organs or tissues. The scanning process occurs afterward and typically lasts 30 to 60 minutes. Prior to the PET-CT scan, patients are often required to fast for several hours to ensure accurate results, especially for scans focusing on the abdomen. Additionally, individuals are advised to abstain from strenuous physical activity for a day or two before the procedure. It is essential to inform the healthcare provider about any medications, allergies, or existing medical conditions, as they may influence the preparation and execution of the scan. PET-CT scans are commonly recommended for individuals with suspected or diagnosed cancers, as they provide valuable information about the location, size, and metabolic activity of tumors. They are also employed in evaluating the effectiveness of ongoing cancer treatments. Additionally, PET-CT is used in cardiology to assess blood flow to the heart and in neurology for brain imaging studies. After the scan, a specialized radiologist interprets the images and generates a comprehensive report for the referring physician. The results aid in making accurate diagnoses, determining the stage of diseases, and formulating effective treatment plans. The collaboration of PET and CT technologies in a single imaging session makes PET-CT a pivotal tool in modern medicine for precisely evaluating structure and function within the human body.
