Diagnostic imaging encompasses various non-invasive medical tests that create visual representations of internal body parts, tissues, and organs to help physicians diagnose and monitor diseases, injuries, and medical conditions.
Common types include X-rays, Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI), ultrasound, and nuclear medicine scans (e.g., PET scans). Each method provides unique information about the body's internal structures.
Most diagnostic imaging procedures are very safe. Techniques involving ionizing radiation (like X-rays and CT scans) are used carefully, with benefits typically outweighing potential risks. MRI and ultrasound do not use ionizing radiation.
Preparation varies depending on the specific test. Some require fasting, avoiding certain medications, or drinking contrast agents. Always follow the specific instructions provided by your doctor or the imaging center.
