The doctor is very concerned about Janine's body composition and needs to know the exact percentage of body fat she has and where the body fat is stored. Which of the following would be the BEST test for the doctor to order?

An MRI can show body tissues in detail, including where fat is stored, and can be used to assess body composition. A waist-to-hip ratio and BMI are indirect measures, while calipers estimate fat under the skin at selected sites rather than showing its overall distribution. Therefore, MRI is the best choice.
