The Role of PET-CT Scans in Effective Cancer Detection
Positron Emission Tomography and Computed Tomography (PET-CT) is a high standard of cancer imaging that combines two powerful technologies to provide advanced details about the presence of cancer in a patient and the cancer’s location in the body. The doctor orders a PET-CT scan when you display unusual symptoms after a physical exam or when they notice something unusual during an X-ray or MRI scan to look for the presence of a tumor. Here’s how PET-CT helps in identifying cancer fast : • A combined PET-CT scan provides detailed information about a tumor compared to using a PET or CT scan alone. The PET-CT scan provides both the anatomy and metabolism of lesions in the body and improves the accuracy of diagnosis, therefore, reducing the number of scans the patient needs. • The CT part uses multiple X-ray images to provide clear, detailed images. It shows anatomic images of tumors while the PET helps in detecting the presence of positrons which are microscopic particles with p
