Radiological studies are medical tests that use imaging techniques to visualize the inside of the body. Common methods include X-rays, CT scans, MRI, and ultrasound. These studies help doctors diagnose conditions, monitor diseases, and plan treatments by providing detailed images of organs, tissues, and bones. These imaging techniques work by using different forms of energy, such as radiation or sound waves, to create pictures of the body's structures. Radiological studies are non-invasive and typically quick, making them essential tools in modern medicine for assessing health and guiding patient care.
