目的 评价3.0T MR在肩袖损伤中的诊断价值,对肌腱断裂的定性、定量诊断价值.方法 回顾性分析35例经手术及关节镜证实的肩袖损伤患者,3.0T MR对肌腱断裂的定性、定量诊断与手术及关节镜进行对比.结果 35例均有不同程度的肩袖损伤,部分患者为复合伤:冈上肌肌腱损伤29例,包括19例肌腱部分断裂,10例完全断裂;冈下肌肌腱损伤7例,5例肌腱部分断裂,2例为完全断裂;肩胛下肌肌腱损伤3例,2例肌腱部分断裂,1例为完全断裂.结论 3.0TMR对肩袖损伤有非常重要的应用价值,肌腱撕裂的定性与定量诊断对术前有明确的指导意义.

目的：探讨3.0T磁共振M RA诊断颅内动脉成窗畸形的临床价值，了解颅内动脉成窗畸形的M RA表现、好发部位。方法回顾性分析2012-04-2013-02我院22例颅内动脉成窗畸形患者的影像学特点、畸形好发部位、类型及合并其他颅内血管性病变。22例均行颅脑磁共振血管成像（magnetic resonance angiography ，MRA）扫描，再将原始图像经 AW4.5工作站采用M IP及V R两种方法进行血管重组，并对血管图像进行后处理。结果22例颅内动脉成窗畸形患者中，单发19例，多发3例，共25处。其中19例单发病例中位于基底动脉6例，位于前交通动脉区3例，位于大脑前动脉10例；3例多发病例中，位于基底动脉及左大脑前动脉1例，位于左椎动脉颅内段及左大脑前动脉1例，位于基底动脉及前交通动脉1例。22例中合并其他颅内血管性病变者20例（90.9％），双侧动脉对比一侧优势者16例，伴AVM1例，永存三叉动脉1例，大脑前动脉A1段缺失8例，血管狭窄2例。结论3.0T磁共振M RA能清楚显示颅内动脉成窗畸形的位置、形态及合并颅内其他血管病变，是诊断颅内动脉成窗畸形首选、有效、无创的影像检查方法。

Objective: Explore 3.0 T MRA diagnosis of intracranial artery into the window deformity clinical value, understanding of intracranial artery into window deformity the MRA performance, the predilection sites, as wel as the value of clinical application. Methods:A retrospective analysis of the April 2012 to February 2013, a total of 22 cases of intracranial arteries into window deformity in patients with the imaging features, deformity predilection sites, type its combined with other intracranial vascular lesions. 22 cases underwent brain MRA scan, then the original image AW4.5 workstation using two methods of MIP and VR vascular reorganization, and vascular image processing. Results:22 cases of intracranial arteries window deformity patients, single 19 cases, multiple three cases, a total of 25. 19 patients with single cases in the basilar artery in six cases, three cases located in the anterior communicating artery, located in the anterior cerebral artery 10 cases. Three cases frequently occurring example, in the basilar artery and left anterior cerebral artery in 1 case, in the left vertebral artery intracranial segment of the left anterior cerebral artery in 1 case, in the basilar artery and the anterior communicating artery in 1 case. 20 patients with other vascular lesions in 22 cases, 90.9%, contrast side of the advantages of bilateral artery in 16 patients, with AVM 1 case, trigeminal artery in 1 case, A1 segment of anterior cerebral artery deletion in 8 cases,vascular stenosis in 2 patients. Concluson:3.0 T MRA can clearly show the intracranial arteries window demformity position, morphology and other intracranial vascular lesions, the diagnosis of intracranial into windows deformity preferred, effective, non-invasive imaging method.

Objective To compare the application value between MT technology and 3D-TOF in MRA. Methods Eighty-two patients accepted MRA scanning by both MT technique and conventional 3D-TOF method ,the original images of the both kinds were done with three-dimensional reconstruction and analyzed.Results MT MRA vascular background was completely inhibited ,branches of small vessels were clearly displayed ,and the vascular background suppression of conventional 3D-TOF MRA was not complete ,peripheral branches of small vessels were not clear or not shown.Conclusion The MT method is su-perior to the conventional 3D-TOF method MRA to obtain high clear vascular images.

Objective:To evaluate the value of multi-slice computed tomography in diagnosis of tendon or ligament injury.Methods:Analysis retrospectively the CT diagnosis of tendon or ligament,some compare with diagnosis of MRI or operation results.Results:In the 24 injures of knee ligaement,11 cases of anterior cruciate ligament injures,8 cases of posterior cruciate ligament injures,6 cases of outside assistant ligament injures;4 Achilles tendon injures were found,in addition,3 cases un-whole laceration,1 cases fracture.Conclusion:The limition of displaying by MSCT in the slice ligament,but very good in the tendon or rough ligament,the diagnosis was accurate,provide an effective consultation to diagnosis or medicat treatment.
