Comparative Study in the Femoral Anteversion measured by CT and MR Imaging as a PACS Image Viewer / 대한의료정보학회지

ABSTRACT

CT and MR have been used successfully to estimate the femoral anteversion angle. It is measured by means of the axis of head and neck of the femur and the knee axis. At the present time, widely used computed tomography method of measuring anteversion on femoral necks of patients. In this study, femoral anteversion angles in 36 years old human adult femur was determined by CT and MR imaging and the measurements compared. Measurement by the manual method and image viewer of computed tomography to determine the anteversion of femoral head were carried out on both femurs. On CT, the mean angle for adults was 20.1degrees. On MR imaging, the mean angle for adults was 20.4degrees. The correlation coefficient between angles determined by CT and MRI scan(r=.80). The femoral anteversion angles by MR imaging exceeded those obtained by CT. No significant difference was observed between the CT and MR imaging. MR imaging is recommended for prospective planning very usefulness in the measured the angle of the femoral anteversion.
