There are several imaging techniques for determining total and regional body composition. Magnetic resonance imaging (MRI) provides cross-sectional images that can be used to determine total adiposity and are one of the most accurate tools available for quantifying body composition at a tissue level. Along with computed tomography (CT), MRI is often considered the criterion measure for assessing intra-abdominal fat and skeletal muscle in vivo. Other imaging techniques such as dual energy x-ray absorptiometry (DEXA) and ultrasound are also useful clinical techniques for assessing total and intra-abdominal (visceral) adiposity. The strengths and weaknesses of DEXA and ultrasonography are addressed in another section.
