目的：探讨腰椎慢性布氏杆菌病的影像学诊断特点，提高对腰椎慢性布氏杆菌病的影像学认识，掌握腰椎慢性布氏杆菌病的影像诊断及鉴别诊断。方法收集2013年6月至2015年10月共26例病例经手术证实或临床实验室证实的腰椎慢性布氏杆菌性病变的影像资料，包括腰椎 X 线片，CT 扫描并行 MIP、VR、MPR、MRI 检查，并结合患者实验室检查结果，进行回顾分析。结果腰椎慢性布氏杆菌病好发于下腰椎，本组病例共19例累及腰4椎体，15例累及腰5椎体，均可见病变椎体骨质破坏和修复共存，骨质破坏同时伴有骨质增生硬化，且到后期增生硬化改变多于骨质破坏，同时伴有椎间盘破坏，椎间隙变窄，周围韧带钙化，亦可伴椎旁脓肿形成等改变，多排螺旋 CT 扫描多方位可清晰显示骨质破坏及增生硬化改变，磁共振平扫检查更加明确病变累及椎体及椎间盘信号改变，椎体周围脓肿范围等。结论腰椎慢性布氏杆菌病在影像学表现上有其特征性改变，但该病常常需要与脊柱结核鉴别，根据影像学表现，结合实验室检查及临床病史，即可做出正确诊断。

　　目的研究MRI诊断前交叉韧带(ACL)损伤的临床意义。方法对经关节镜确诊且均行MRI检查的207例临床怀疑ACL损伤患者进行回顾性分析。结果207例急性膝关节外伤患者中，以膝关节镜为依据，MRI诊断结果：ACL损伤173例,其中部分性撕裂115例，符合率为93.9％；完全性撕裂58例，符合率为100％；ACL完好的34例，符合率为100％。结论 MRI是诊断ACL损伤的重要手段。MRI作为一种无创性检查方法，在前交叉韧带损伤的准确诊断上具有很高的价值，为临床制订治疗方案提供可靠依据。

Objective To evaluate the multiple-detector spiral CT imaging of adrenal pheochromocytoma and improve CT diagnostic accuracy.Methods Pathologically confirmed by surgery and a complete medical history data of 20 cases of adrenal pheochromocytoma in CT performance characteristics were retrospectively analyzed.Results Of the 20 cases of adrenal pheochromocytoma,1 case was bilateral,the rest were single,there were a total of 21 lesions.Single lesion were in 19 cases,10 in right,9 in left.The diameter of was 2.0~11.8 cm,the average was 7.1 cm,diameter ≤3.5 cm in 6 cases,3.5~5.0 cm in diameter in 7 cases,diameter ≥5.0 cm in 8 cases.Adrenal pheochromocytoma scan showed homogeneous low density,mixed density or mass in the center of three cases of lesions with calcification,granular or the edge of the limitations of the ring calcification.Solid part of all cases in the arterial and venous phase was significantly enhanced,CT scan increase 40~80 HU than plain scan.Conclusion The adrenal gland is significantly larger mass with heterogeneous enhancement,combined with clinical data,can suggest the diagnosis of pheochromocytoma.

<正>1975年Hijkata首次采用经皮穿刺置入套管针后,用垂体钳摘除髓核治疗腰椎间盘脱出症获得满意疗效后,这一介入治疗方法逐渐被广泛推广。经皮腰椎间盘摘除术(PLD),由于创伤小,可重复性强,并发症少,康复快,费用低等特点,为治疗腰椎间盘突出症开辟了新的途径。我院近来在CT引
