查询词典 non attenuation wave

In 2007, we performed 804 SPET/CT services in many aspects. Integrating CT was used for CT attenuation correction or morphological image fusion.

Results: In 2007, we provided 602 SPET/CT services in myocardial perfusion scan for attenuation correction and 202 SPET/CT services in other scans for image fusion. Among 64 regional bone SPET/CT services, we noted 2 (3.13%) significant motion artifacts and 2 (3.13%) streak artifacts induced by beam hardening effect while among 25 Ga-67 local SPET/CT services. According to the features including low tube currents and slow rotating speed of this SPET/CT, some problems such as the patient safety, longer scan time, alignment mismatch and radiation protection would be analyzed and discussed.

结果：2007年804例SPET/CT造影中，602例心肌血流灌注断层摄影进行衰减校正，共202例病例进行影像融合，其中鎝－99m-MDP局部SPET/CT发生「影像上明显可见的移动假影」的比例为3.13%(2/64)，镓－67局部SPET/CT发生移动假影的比钊则为24%(6/25)，因射束硬化效应所造成的条状假影有产生干扰融合影像判读的情形，其他问题包括SPET/CT之CT低管球电压及低转速之机器特性、受检者的安全、较长的造影时间、对位错误及辐射防护筝。

Results Thirty-one(7.64%) of 406 patients showed abnormal ventilatory function, while 165 of 404 patients showed diffusing abnormality. Of the 434 patients who had received HRCT scans,151(34.79%) showed abnormalities including subpleural and basal ground-glass and reticular attenuation,nodular septal thickening and bronchiectasis. Of the 395 patients who had received both lung function test and HRCT scanning,55(13.92%) had abnormalities both in the lung function and HRCT.

结果 在4 0 6例进行肺通气功能检测的患者中，31例(7 6 4 %)异常；4 0 4例进行肺弥散功能检测，其中16 5例(40 84 %)异常；4 34例进行胸部HRCT检查，15 1例(34 79%)异常，表现为磨玻璃密度阴影、网格状阴影和胸膜下弧线影等；395例同时接受肺弥散功能检测和胸部HRCT检查，5 5例(13 92 %)两项均异常，且HRCT显示双肺病变典型者的肺弥散功能较HRCT正常者有显著的下降，两组差异有统计学意义。

Linear opacities appeared in pulmonary fibrosis of gradeⅡor gradeⅢand had statistical significance(P＜0.05);Bullae and pneumothorax were mainly in pulmonary fibrosis of gradeⅢ,difference of appearance of the sign had statistical significance(P＜0.05).The difference of appearance of ground-glass attenuation,consolidation,nodules and subpleural interstitial thickening had no statistical significance in different stages of pulmonary fibrosis. Honeycomb lung and traction bronchiectasis appeared in pulmonary fibrosis of gradeⅢ.

线状影出现于Ⅱ级和Ⅲ级PF，且具有统计学意义(P＜0.05)；肺大泡及气胸主要出现于Ⅲ级PF，与其余各级PF之间存在差异(P＜0.05)；磨玻璃影、实变、结节影及胸膜下间质增厚在各级PF出现的差异无统计学意义；蜂窝肺及牵引性支气管扩张都出现于Ⅲ级PF。

Linear opacities appeared in 14d group and 28d group,bullae and pneumothorax were mainly in 28d group,the difference of appearance of two signs above had statistical significance(P＜0.05).The difference of appearance of ground-glass attenuation and consolidation had no statistical significance in sub-groups.Nodules and subpleural interstitial thickening did not appear in 3d group.

线状影出现于14d组及28d组，肺大泡和气胸主要见于28d组，上述两个征象出现的差异具有统计学意义(P＜0.05)；磨玻璃影和实变在各组中出现的差异无统计学意义；结节影和胸膜下间质增厚在3d组均未出现；蜂窝肺1只及牵引性支气管扩张2只都出现于28d组。3。
