Imaging plays a crucial role in oncology, providing essential information about the size, location, and spread of cancerous tumors. Two major imaging techniques widely used in oncology are PET-CT and MRI.
PET-CT combines the capabilities of PET (positron emission tomography) and CT (computed tomography) to provide detailed information about metabolic activity within the body. PET scans involve the injection of a radioactive tracer into the body, which accumulates in tumors and other metabolically active tissues. The PET scan then captures images of the distribution of the tracer, providing insights into tumor location, size, and metabolic activity.
MRI is a non-invasive imaging technique that provides detailed anatomical images of the body. MRI uses powerful magnetic fields and radio waves to create detailed images of tissues, including tumors. MRI can be used for various purposes, including tumor staging, diagnosis, and monitoring disease progression.
Examples:
A PET-CT scan can help identify a tumor in the brain that is not visible on an MRI.
An MRI can be used to diagnose lung cancer, a disease that is not typically detectable on PET scans.
PET-CT is often used in combination with MRI for comprehensive imaging of tumors
