就是想问下 1、标题的翻译 Semi-automatic analysis of standard uptake values in serial PET/CT studies in patients with lung cancer and lymphoma 我翻成了:肺癌和淋巴癌患者在PET/CT系列检测中的标准化摄取值的半自动化分析 2、第一个笑脸处:The semi-automatic method first aligns the serial PET/CT studies based on the CT images. 3、第二个笑脸处:Three readers中的readers指什么 4、第三个笑脸处: the line of identity for all readers Abstract Background: Changes in maximum standardised uptake values (SUVmax) between serial PET/CT studies are used to determine disease progression or regression in oncologic patients. To measure these changes manually can be time consuming in a clinical routine. A semi-automatic method for calculation of SUVmax in serial PET/CT studies was developed and compared to a conventional manual method. The semi-automatic method first aligns the serial PET/CT studies based on the CT images. Thereafter, the reader selects an abnormal lesion in one of the PET studies. After this manual step, the program automatically detects the corresponding lesion in the other PET study, segments the two lesions and calculates the SUVmax in both studies as well as the difference between the SUVmax values. The results of the semi-automatic analysis were compared to that of a manual SUVmax analysis using a Philips PET/CT workstation. Three readers did the SUVmax readings in both methods. Sixteen patients with lung cancer or lymphoma who had undergone two PET/CT studies were included. There were a total of 26 lesions.Results: Linear regression analysis of changes in SUVmax show that intercepts and slopes are close to the line of identity for all readers (reader 1: intercept = 1.02, R2 = 0.96; reader 2: intercept = 0.97, R2 = 0.98; reader 3: intercept = 0.99, R2 = 0.98). Manual and semi-automatic method agreed in all cases whether SUVmax had increased or decreased between the serial studies. The average time to measure SUVmax changes in two serial PET/CT examinations was four to five times longer for the manual method compared to the semi-automatic method for all readers (reader 1: 53.7 vs. 10.5 s; reader 2: 27.3 vs. 6.9 s; reader 3: 47.5 vs. 9.5 s; p < 0.001 for all).Conclusions: Good agreement was shown in assessment of SUVmax changes between manual and semi-automatic method. The semi-automatic analysis was four to five times faster to perform than the manual analysis. These findings show the feasibility of using semi-automatic methods for calculation of SUVmax in clinical routine and encourage further development of programs using this type of methods.

摘要 背景:串行PET / CT研究之间变化最大标准摄取值( SUVmax值)来确定肿瘤的患者疾病进展或消退。手动测量这些变化可能会非常耗时在临床常规。半自动方法SUVmax值在串行PET / CT检查计算的开发和相比,传统的手工方法。半自动方法首先对齐根据CT图像序列PET / CT研究。此后,将读取器选择在PET研究中的一个异常病变。在此之后手动步骤,程序会自动检测相应的病变在其他的PET研究中,段两个病灶,并计算SUVmax的研究,以及对SUVmax值值之间的差异。半自动分析的结果进行了比较,其使用飞利浦PET / CT工作站手动SUVmax值分析。三读者做了SUVmax值读数这两种方法。 16例肺癌或淋巴瘤谁曾经历了两次PET / CT的研究都包括在内。共有26病变者。 结果:在变化SUVmax值的线性回归分析显示,截距和斜率接近身份的行为所有读者(读者1 :截距= 1.02 , R2 = 0.96 ;读者2 :截距= 0.97 , R2 = 0.98 ;读卡器3 :截距= 0.99 , R2 = 0.98 ) 。在所有情况下手动和半自动方式同意SUVmax值是否增加或串行研究之间下降。的平均时间来衡量两个串行的PET / CT检查SUVmax值变化为四到五倍再为手动方法相比,半自动方法为所有读者(读者1 : 53.7与10.5秒;读者2 : 27.3对比6.9秒;读卡器3 : 47.5与9.5秒,P < 0.001) 。 结论:良好的协议显示在手动和半自动方法SUVmax值之间变化的评估。半自动分析更快的四到五倍比手动分析来执行。这些结果显示了使用半自动方法SUVmax值的计算在临床常规和鼓励的项目进一步发展使用这种类型的方法的可行性。 关键词:图像分析,放射性核素显像,定量 |
