Cancer Dictionary

Ultrasound is a medical imaging technique that utilizes high-frequency sound waves to create images of internal body structures, such as organs, tissues, or blood flow. It's a non-invasive and safe diagnostic method used widely in medicine, particularly in obstetrics for pregnancy monitoring and diagnosis of related conditions.

A PET/CT scan is a combination of two imaging techniques. PET (Positron Emission Tomography) reveals the body's metabolic activity, while CT (Computed Tomography) provides detailed anatomic information. By merging these two techniques into a single scan, doctors can more accurately diagnose, monitor, and treat diseases, particularly cancer, by pinpointing their exact location and extent in the body.

A bone scan is a nuclear imaging test that helps diagnose and track several types of bone diseases and conditions. It involves injecting a small amount of radioactive material, which then travels through the bloodstream and is absorbed by the bones. A scanner detects and measures the radiation, creating images or "maps" of bone metabolism for analysis.
