Abstract:
Objective To investigate the techniques of lower limbs MRI. Methods 50 patients underwent lower limbs MRI examinations on 1.5T scanner using 4-channel torso coil, in which 28 were femur and 22 were tibia and fibula. Pulse sequences included FSE T2WI and SE T1WI. All FSET2WI were added with fat saturation. FOV is 42cm?42cm. Imaging planes included axial, coronal and saggital views. Slice thickness ranged from 8mm to10mm on axial and 4mm to 5mm on sagital or coronal view. Results Axial view could delineated the anatomical relationship of the lesions. Coronal or sagital view could show the global view and relation to the adjacent structure. Conclusion The proper scan skill, optimized parameters and proper pulse sequences are essential for better delineation of the anatomy of the lower extremities and helpful for the location and the diagnosis.
