多排螺旋CT在骨关节创伤中的诊断价值【摘要】目的：探讨16层螺旋ct三维重建技术在骨关节创伤性疾病中的诊断价值。

方法：骨关节创伤92例，伤患处均行16层螺旋ct横断面扫描，在工作站行三维重建技术后处理，即表面遮盖显示(ssd)、多平面重建(mpr)及容积重建(vr)技术，与x线平片比较，评价3种重建方法对骨折或脱位的显示效果。

结果 16层螺旋横断面检出91例，mpr重建对所有骨折的部位及形态全部明确诊断，获ssd重建技术明确诊断89例，获vr重建技术明确诊断90例。

经16层螺旋ct横断面扫描可发现细小骨折，但立体信息不足；三维重建技术可多角度、全方位观察骨折部位的骨结构空间关系，ssd能立体、逼真地显示骨折及脱位情况，mpr能兼顾软组织的改变，在骨折线走行和移位程度具有优势，在显示细小的骨折线上更具优势。

结论：各种三维重建技术各有优势，与16层螺旋ct联合使用可提高对骨关节损伤诊断的准确性，为临床诊治提供更多准确、直观的信息。

.6中国医疗器械信息 | China Medical Device Information论著Article隐匿型肋骨骨折是指用常规X 射线检查难以发现或难以及时发现的骨折，经过一段时间治疗或者用其他影像学检查方法才能发现的骨折。

在影像学中，肋骨骨折的X 射线片和CT 片的成像特点不同，由于X 射线检查的灵敏度和肋骨解剖学的结构特殊性，对于有错位的骨折可诊断明确，比较轻微和重叠区的骨折难以及时发现，而且由于患者体位、投照位置和角度、以及条件限制，传统X 射线片难以充分地展示骨折的部位和数目，易发生漏诊；CT 检查优于X 射线检查之处在于其密度分辨率高，图像清晰，解剖关系明确，能提供没有组织重叠的横断面图像，且三维重建可进行冠状面、矢状面以及三维立体图像的重建，可以更逼真地显示病变的部位图像，弥补了X 射线片和常规CT 检查的不足，提高了骨折诊断的准确性[1]。

为了研究探讨隐匿型肋骨骨折在64排螺旋CT 三维重建的检查与应用价值，为临床诊疗及法医鉴定提供准确的诊断依据。

Methods: A total of twenty-eight patients with thoracic and abdominal aortic disease were selected to undergo 3DCE-MRA examination with conventional T 1-weighted image (T 1WI) and T 2-weighted image(T 2WI) of plain scanning axis position. Low-dose contrast agent was adopted to undergo single layer dynamic scanning of axial position so as to obtain the delay time of scan. And then, the plain scan collected coronary images of target blood vessels as the mask of post subtraction. The obtained delay time in the last step was used to undergo 3DCE-MRA. After contrast agent was injected, the coronary images of target blood vessels and the subtraction of mask pre enhancement were respectively collected at arterial and venous phases. At the last, the axial fast spin echo (FSE) T 1WI post enhancement was collected, and the signal performances of vascular lesions of thoracic and abdominal aorta were observed. Results: In the 28 patients, 5 cases were aorto-arteritis (17.90%), and 1 case was lilac artery aneurysm (3.6%), and 3 cases were atherosclerosis (10.7%), and 6 cases were renal artery stenosis (21.4%) and 13 cases were aortic aneurysm (46.4%). The display effect of 3DCE-MRA technique was favorable for the aortic vessels and branches of chest and abdomen of 28 patients.

方法　选取河北北方学院附属第一医院２０１９年１月至２０２０年１月期间１２０例乳腺肿块性病变患者，经多层螺旋ＣＴ灌注扫描，其中，乳腺癌６３例，良性肿块５７例。

测量分析血流量（ＢＦ）、血容量（ＢＶ）、平均通过时间（ＭＴＴ）、血管表面通透性（ＰＳ）等动态图像数据，依据乳腺癌与良性肿块划分不同组别，实施统计学分析。

结果　乳腺癌组患者的ＢＦ、ＢＶ、ＰＳ均高于良性肿块组，两组差异有统计学意义（Ｐ ０．０５）；两组患者的ＭＴＴ差异无统计学意义（Ｐ ０．０５）；乳腺癌患者的毛细血管数量增多，管径较正常宽，使微血管容量增加，血流加快。

良性肿块患者的微血管密度与乳腺癌实质相似或轻度增多，微血管管径与正常乳腺微血管管径相同，灌注的微血管与非灌注的微血管比例增加不明显。

结论　在乳腺肿块诊断中实施多层螺旋ＣＴ灌注成像扫描，准确率高，利于鉴别、诊断乳腺癌。

磁共振3D-SPC序列及T1-VIBE序列对原发性三叉神经痛的诊断价值发表时间：2016-11-28T17:10:14.180Z 来源：《医师在线》2016年9月第17期作者：肖轶智罗菁吴先衡曾向廷[导读] 原发性三叉神经痛（primary trigeminal neuralgia,PTN）是一种慢性疼痛综合征，好发于中老年女性，发病率约为182/10万人。

The study of diagnostic value of MR 3D-SPC and T1-VIBE sequence of magnetic resonance in primary trigeminal neuralgia 汕头市中心医院医学影像中心，广东汕头 515031 Xiao yi-zhi, Luo jing, Wu xian-heng, Zeng xiang-ting (Medical imaging center of Shantou center hospital, 515031, China) [摘要] 目的：探讨磁共振三叉神经成像对原发性三叉神经痛的诊断价值。

材料与方法：回顾性分析89例诊断为原发性三叉神经痛（单侧疼痛）患者，均接受Siemens 3.0T磁共振三叉神经成像的检查（包括T1-VIBE序列和T2-SPC序列），由两位副高级以上影像医师共同分析病例中三叉神经微血管压迫的影像学征象，并从中归纳三叉神经与邻近血管的关系，评价其显示三叉神经脑池段（REZ）与周围血管关系的能力和优势。

结果：89例患者中，症状侧血管神经Ⅰ型32例，Ⅱ型47例，Ⅲ型10例；而无症状侧Ⅰ型74例，Ⅱ型14例，Ⅲ型1例；双侧压迫程度差异显著，存在统计学意义（P<0.001）。

而在有血管神经接触、压迫情况下，症状侧57个病例中，小脑上动脉为主要的责任血管(63%)。

结论：T2-SPC序列能清晰显示三叉神经与周围结构的关系，T1-VIBE序列是三叉神经MR成像常用的补充序列，T2-SPC与T1-VIBE序列相结合能提供准确的诊断信息，对原发性三叉神经痛的诊断具有重要价值。

Methods One hundred and twenty patients tested by the chest and abdomen enhanced CT examination were selected in Liuzhou Worker' s Hospital from January 2010 to July 2011. They were divided into A,B and C groups, A:liver arterial phase,lung,liver venous phase, scanning direction: head to foot; B: liver arterial phase, lung and liver venous phase, scanning direction:head to foot;C :liver arterial phase and lung,liver venous phase,scan direction:foot to head. The CT images were evaluated by double-blind trials. Results The image quality of C group was better than A and B group. The differencesamong the three groups were statistically significant ( P < 0. 05 ). The differences between A group and B group were not statistically significant (P > 0. 05 ). The differences between A group and C group, B group and C group were statistically significant ( P < 0. 05 ) .

螺旋CT肺灌注显像对肺气肿分析与评价摘要】目的：探讨螺旋CT肺灌注显像对肺气肿的诊断价值。

方法：选择我院治疗的慢性阻塞性肺气肿患者27例作为观察组，选择同期27例健康体检者作为对照组，均采用螺旋CT肺灌注显像，观察两组血流量、血容量、平均通过时间和肺表面通透性情况。

结果：观察组患者在血流量、血容量和表面通透性情况均低于健康体检者，组间对比差异有统计学意义（P＜0.05）。

结论：CT灌注显像属于无创诊断与评价的方法，能够为早期诊断慢阻肺提供相应的依据，但在技术层面需要进一步探讨。
