Q: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
Abstract: Magnetic resonance imaging (MRI) is a powerful new tool for the study of human anatomy and pathology. By various MRI techniques, the structure of the middle and inner ears of aborted 20-week fetuses is defined and compared to gross anatomic sections. MRI's potential for evaluating temporal bone development and diseases of the ear is discussed.
Question: Does the abstract contain any numerical data?
