Diagnostic imaging is a medical technique that helps doctors see inside the body to diagnose health issues. It uses various technologies, such as X-rays, MRI (Magnetic Resonance Imaging), and CT scans (Computed Tomography), to create detailed images of organs and tissues. These images allow healthcare professionals to identify problems like fractures, tumors, or infections without needing invasive procedures. The process of diagnostic imaging is usually quick and painless. Patients may need to lie still while the machine takes pictures, and some imaging methods might require a contrast dye to enhance the images. Overall, diagnostic imaging plays a crucial role in modern medicine, aiding in accurate diagnosis and treatment planning.
