Imaging Diagnosis in Orthopedics: A Basic Introduction to the Interpretation of MRI
Although interpretation of simple X-ray films is an excellent first step in imaging diagnosis in orthopedics, the recent advance of magnetic resonance imaging (MRI) has had a great impact on this field. MRI is often compared with X-ray computerized tomography (CT) due to the similarity of their images. The principles of X-ray absorption governing the reading of conventional X-ray film can be directly applied to the interpretation of X-ray CT. However, MRI is produced by the principle of magnetic resonance, a technique fundamentally different from that of roentgenography. Thus, it is essential for clinicians to understand the basic principle of MR in order to correctly interpret the information provided by MRI.
