Figure Lengend Snippet: Measurement of proton density fat fraction (PDFF) of the multimodal simulators/phantoms by magnetic resonance imaging Toshiba Titan 1.5 (Canon Medical Systems Corporation, Japan). A-B : axial sections of phantom series with different fat content in the filler: blue – filler without fat or no steatosis; yellow - mild steatosis (S1); orange - moderate steatosis (S2); red - severe steatosis (S3). (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)

Article Snippet: The Varta Medical Center of Vision Partner LLC had a Toshiba Titan 1.5 (Canon Medical Systems, Japan) magnetic resonance imaging scanner with proton density software module (MRI-PDFF) and a 128-slice Aquilion TSX-101 A multidetector computed tomography scanner (Canon Medical Systems, Japan).

Article Title: Modulation of the brain's functional network architecture in the transition from wake to sleep

doi: 10.1016/B978-0-444-53839-0.00018-1

Figure Lengend Snippet: Map of regions used in global network analysis of the transitional states from wake to sleep are illustrated as spheres centered on the coordinates for 151 regions of interest derived from a meta-analysis of task fMRI studies. Spheres are illustrated larger than 10 mm for ease of visualization. The legend indicates the meta-analysis task region nearest the combined region illustrated.

Article Snippet: Whole brain fMRI BOLD (Siemens Allegra 3T scanner; Erlangen, Germany; TE = 30 ms, 4 mm 3 voxels, 2.013 s per volume, 1 s pause between frames) was acquired using an EPI sequence locally modified to enhance the signal/noise ratio.

Techniques: Derivative Assay

Figure Lengend Snippet: Community structure in the wake state global network architecture. CARET maps show the communities to which each of 151 regions of interest were assigned. Notably, regions segregate into communities whose anatomical locations are consistent with a set of neural networks (legend) defined both on task and resting state fMRI. The central map illustrates community structure using the SoNIA visualization tool based on modularity analysis of global network structure. Subnetwork connectedness and the degree to which each community segregates from others in the network can be seen using this tool.
