CAMRT Radiography Practice Exam

Which imaging technique is used to visualize soft tissue structures?

1. X-Ray

2. CT Scan

3. Ultrasound

4. MRI

The correct answer is: MRI

The technique used to visualize soft tissue structures effectively is MRI (Magnetic Resonance Imaging). MRI utilizes strong magnetic fields and radio waves to produce detailed images of the internal structures of the body, particularly soft tissues such as muscles, ligaments, organs, and the brain. Unlike X-rays and CT scans, which primarily provide good visualization of bony structures and may use ionizing radiation, MRI excels in differentiating between various types of soft tissue due to its high contrast resolution. This characteristic makes MRI especially useful in diagnosing conditions related to the nervous system, musculoskeletal system, and in imaging various organs such as the heart and liver. Therefore, for the purpose of evaluating soft tissue, MRI is the preferred imaging modality.
