The topic of age estimation in living persons is important for sports competitions as well as unaccompanied minors without valid documents and has recently gained interest. Recommended imaging protocols are based on modalities using ionizing radiation and therefore MRI is currently investigated for its eligibility to replace these measurements. This study investigates the accuracy of MRI-based age estimation for retrospectively undersampled data to determine the degree of inaccuracies introduced by an acceleration of the acquisition technique using commercially available undersampling strategies. For this purpose the data is analyzed by a radiologist and using an automatic method.
