performed, with more than 400 patterns of testing. Magnetic resonance imaging of the brain or spine was ordered in 23.2 % of patients, whereas a glucose tolerance test was rarely obtained (1.0 %). Mean Medicare expenditures were significantly higher in the diagnostic period than in the baseline ...
LV diastolic function (R(2) = 0.21), right ventricular ejection fraction (R(2) = 0.13), N-terminal fragment of the pro-brain natriuretic peptides (R(2) = 0.23) and cardiac troponin (R(2) = 0.33). The
Brain structure in later life reflects both influences of intrinsic aging and those of lifestyle, environment and disease. We developed a deep neural network model trained on brain MRI scans of healthy people to predict “healthy” brain age. Brain regio
Brain MRI protocol and image processing We collected the following brain MRI sequences: T1-weighted, T2-weighted, and Fluid Attenuated Inversion Recovery (T2-FLAIR) MRI (see Supplemental Material for details). We used brain 2D or 3D T1-weighted scans to segment grey and white matter tissues, ...
The specialties of the physician requesting a first-trimester MRI were family medicine (44%), brain sciences (14%), and other specialties (27%), including general surgery (5%), orthopedic surgery (6.5%), and internal medicine (5%) (Table 1). For gadolinium-enhanced MRI, the requesting spec...
Brain activation patterns of children with DD (N = 18) and control children (N = 20) during each condition are depicted on the SPM standard brain template. The activated brain regions shown had been subjected to a FWE or FDR correction with a minimum number of 10 voxels, with one ...
(ICD9, ICD10, or OPCS-4) consistent with BAV and followed by manual annotation. The validation and test sets were sampled at random with uniform probability from all 14,328 MRI sequences to capture the BAV class distribution expected at test time. Development and validation set MRIs were ...
