The spectrum of MRI-PDFF, MRS, and two different histopathologic methods (AI vs. pathologist) in quantifying hepatic ste
trials.MRI-PDFF and MR elastography are the most common primary and secondary endpoints in NASH trials, respectively.To identify Fibro-NASH, the MRI-AST (MAST) score was created based on these MRI techniques.The MAST score was proven to outperform the FIB-4, NAFLD fibrosis, and FAST scores...
MRE-LSM followed by PDFF + cT1 mpMRI: Multiparametric MRI MRE: Magnetic resonance elastography NAS: NAFLD activity score NPV: Negative predictive value PcT: PDFF + cT1 PDFF: Proton density fat fraction PPV: Positive predictive value VCTE: Vibration-controlled transient elast...

registration-error (TRE) between each MRI and the planning-CT image was calculated. Fiducial marker visibility was rated by two medical physicists with over three years of experience examining MRI-only prostate simulation images. The rater's classification accuracy was quantified using the F 1 score...
surgery for MRI-based VBQ score. And it can be used as an opportunistic screening index while lacking bone density T score.Keywords: Bone density; Vertebral bone quality score; Magnetic resonance imaging; Dual-energy X-ray absorptiometry; Osteoporosis * 通信作者，E-mail ：272279562@qq.com ...
The scale contains the four subscales of "Well-being", "Self- control", "Emotionality", and "Sociability", which can be averaged to one "Global Trait Emotional Intelligence" score. Answers are rated in a 7-point Likert format, ranging from 1 (do not agree at all) to 7 (agree ...
The subject was then asked to finish the remaining test independently, and his/her final score was recorded. For novices, their knowledge/skills about Chinese chess were collected. All above- mentioned information was summarized in the phenotypic data table in Supplementary File 1 and 2. MRI ...
1.5 功能性肝脏成像评分(functional liver imaging score,FLIS) Bastati等[53]回顾性研究128例慢性肝病患者,提出FLIS基于3项指标:(1)肝实质增强(EnQS,0～2分);(2)胆道造影剂排泄(ExQS,0～2分);(3)门静脉相对于肝实质的信号强度,即门静脉征(PVsQS,0～2分)。FLIS为这3项指标评分的总和,通过单变量分析...
