,Typically, at least two b-values should be used during DWI in order to enable meaningful ADC interpretation,although accuracy increases when more b-values are used. 虽然使用更多的b值提高精确度,通常情况下至少两个b值。 In our study, we had used b-values of 0 s/mm2 and 600 s/mm2 in ...
ADCfast and f value 1.5 统计学处理 采用SPSS 22.0软件进行统计学分析.首先, 分别对CGPCa,SH,GH三组患者的ADC ,total ADCfast,ADCslow,f值数据进行正态性检验,采用x±s 进行统计学描述.其次,对各组数据进行 方差齐性检验,采用方差分析,LSD-t检验比较 各参数差异性.将SH与GH患者共同作为BPH 组,比较各...
Image analysis and data interpretation The PET/MRI examinations were transferred to the main workstation and the patients were assessed by the physicians of the Oncoradiology team at the Baka Jozsef Oncoradiology center. The ADC map generated from the DWI was used for the measurement of the ADC...
Diffusion-weighted MRI is a key part of both the first and second PI-RADS standards for interpretation of prostate MRI10,18. Numerous studies have shown that restricted diffusion is the single most reliable predictor of cancer on multi-parametric MRI. Some recent studies have proposed that imaging...
The mean ADC values for malignant lesions were (0.84×103±0.1SDmm2/s), while that for benign lesions were (1.8×103±0.5SDmm2/s), with cut off 1.2×103 and p value=0.005. Mature teratomas showed restricted diffusion with ADC values 0.8×103mm2/s (false positive), due to mixed ...
