Quizplus · Accepted Answer

A noninvasive technique implies that it is not an experimental study using invasive procedures. Therefore, options A and C can be eliminated. The aim of the study is to compare brain structures, which suggests a descriptive type of study. Finally, the study aims to examine the details of the brain structures which makes MRI the best choice since it provides detailed images of soft tissues, including the brain. Therefore, the best choice is descriptive brain imaging study using MRI.
