MRI is similar to CT scan in providing a cross-sectional display of body anatomy with excellent resolution of soft tissue details. It permits identification of soft tissue lesions inaccessible to other imaging techniques. The total avoidance of ionizing radiation, its lack of known hazards, and thepenetration of bone and air with minimal attenuation, makes it particularly attractive as a non invasive technique.
