The displaying value of thin scan of oblique coronal MR images on anterior cruciate ligament

Objective To investigate the value of oblique coronal MR images in visualization of the anterior cruciate ligament(ACL).Methods Conventional scan was performed in 60 normal knees,including axial section,coronal section and median sagittal section.Then thin scan of oblique coronal which was paralled to ACL,based on FSE conventional oblique sagittal images,was acqired.The visualization of ACL on thin scan of oblique coronal,axial,coronal and obligue sagittal were analysed.Results The clear visualization of the whole ACL was 100%(60/60)shown on one image of the thin scan of oblique coronal,86.7%(52/60)on one of the Conventional oblique sagittal images while it was sectionally shown on the images of axial section and coronal section,that is,it can't be completely shown on one image.Conclusion The thin scan of oblique coronal agrees with the dissect trend of anterior cruciate ligament and significantly improves the complete display rate of anterior cruciate ligament,benefiting its assessment after it is damaged.
