| Abstract: | Objective： To investigate the value of three dimensional reconstruction technique of 1.5 T MR in evaluation of anterior cruciate ligament （ACL）. Materials and Methods： Thirty normal volunteers and 11 patients who had ACL injury, underwent MR of knee joint including sagittal scanning of T1WI, fat suppressed-fast spin echo-T2 weight （FS-FSE-T2W）, coronal fat suppressed PDWI and M3D/cube T2WI. All images were reconstructed using ADW 4.4 workstation. The routine MR image and M3D/cube T2W images were compared. Results： Routine MRI： Sixteen cases were showed completely in one image, 14 cases were showed completely in two continues images; All the 30 cases were showed completely in M3D/cube T2WI in normal group. Two cases showed no injury, 3 cases showed ACL partial tears, 6 showed completely collapse in 11 ACL injuries in routine MRI; 5 cases showed ACL partial tears, 6 cases showed completely collapse in M3D/cube T2WI. Conclusion： M3D/eube T2WI could improve the diagnosis rate of ACL, it will be one of the best imaging technique to show ACL. |
