The area under the ROC curve (AUC) of qT1 after enhancement was=0.786, and the diagnostic threshold was 927 ms; the sensitivity was 55.6%, and the specificity was 100%. The AUC of the rate of the percentage change of T1 value was 0.786, and the diagnostic threshold was 42.5%; the ...

原文定位:第8段最后两句 “Then when the punchline arrived, a new area sprang to life — the orbital prefrontal cortex. This patch of brain tucked behind the orbits of the eyes is associated with evaluating information.”(然后,当包揪抖开时,一个新的区域——前额眼眶脑皮层活跃起来。这个蜷缩在眼...

the brain will interpret this information in the quickest way possible. Thus it will draw on both past experience and any other source of information, such as what other people say, to make sense of what it is seeing.(例如,当面对来自眼睛的信息流时,大脑将以最快的方式解释这些信息。 因此,它...
To detect such symptom, for each subject, our algorithm only needs to analyze 3 slices around the center of a MRI DICOM volume, i.e., mid-brain area. In each slice, a window covering the SN becomes the region of interest (ROI) for further analysis. The ROIs are pre-processed by ...
(T2 SE–SE) = 0.46) and an RF field map estimation with little bias (a 4% average deviation from the map acquired with the vendor’s pulse sequence), see Fig.3b. Even low flip angles, in the ill-posed area of the “balloon”, were well determined using the implemented ...
[44], either RNaseL inactivation or loss of RNASET2 could lead to a failure to degrade either extracellular and/or intracellular ssRNAs, which triggers the innate immune response with downstream consequences on development. An important area of research here will be the study of mice lacking RNA...
In addition, the range of T2* relaxation times investigated in this study is specific to the brain at 3 T. If T2* quantification is performed with a short TE range in an area with a short T2* value, such as the liver, it is expected that the benefit of using a bipolar readout ...
