Imaging techniques refer to the use of various technologies to create visual representations of objects or structures within the body, often for medical diagnostic purposes. These techniques can include X-rays, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and more. Each imaging technique has unique advantages and limitations, allowing for the visualization of different aspects of the body's tissues, organs, and systems. These techniques play a crucial role in diagnosing and monitoring a wide range of medical conditions, from broken bones to cancer.
