The module on the anatomy of the brain based on MRI with axial slices was redesigned, having received multiple requests from users for coronal and sagittal slices. The elaboration of this new module, its labeling of more than 524 structures on 379 MRI images in three different views and on ...
labelled structures were meticulously manually contoured on the MRI images according to contrasts and advanced knowledge of DB architecture (Amira 6.4.0, Thermo Fisher Scientific Inc, Waltham, MA, USA). This allowed to show the DB nuclear architecture through 18 axial, 19 coronal and 15 sagittal ...
Perfusion simulations require a volumetric brain mesh with each tetrahedron labelled either as GM or WM. Quasi-patient-specific geometries are obtained by first creating a general mesh template in standard space and then an affine registration of this template to the tissue mask of each specific sub...
The brain MRI protocol included routine sequences as follows: 3D T1-weighted (T1w) images acquired in the sagittal plane (TR/TE = 2090/4.9 ms; resolution = 1 × 1 × 1 mm3); axial, sagittal and coronal T2-weighted (T2w) turbo spin-echo images; axial gradient-...
Transverse and sagittal sections through MRI and attenuation maps generated from the tissue atlas (a) and measured templates (b) (This research was originally published inI. B. Malone, R. E. Ansorge, G. B. Williams, P. J. Nestor, T. A. Carpenter, and T. D. Fryer, “Attenuation corr...
The following sequences were used for whole spine imaging: sagittal whole-spine T1-weighed and sagittal whole-spine T2-weighted sequences. CT was undertaken of the chest, abdomen and pelvis with intravenous contrast according to standard local departmental protocol either within the same institution ...
and sagittal views of the spatiotemporal atlas across multiple GAs. Note that with Algorithm 1 an unbiased average atlas of the fetal brain anatomy is achieved at any given continuous age point, so these are only representative age points. The atlas (CRL fetal brain atlas), along with its la...
(CE)-MRI and sagittal delayedT1weighted acquisitions. The bilateral DW-MRI was acquired in the axial plane with a single-shot spin echo planar imaging sequence, withb-values of 0, 600, 800, 1000 and 1500 s/mm2, TR/TE = 6675 ms/97.3 ms, and 5 signal averages. The acquisition ...
Labeling slice prescription (in blue) in sagittal and coronal views for PASL. Feeding arteries are shown in purple Full size image Background suppression The signal from static tissue fluctuates due to physiological and thermal noise effects. This interacts with the signal derived from ASL, thereby...
Magnified view of PVS in an axial, coronal and sagittal slice in T1-weighted and T2-weighted MR images. The position of these zooms in corresponding T1-weighted brain scans is highlighted with yellow squares (bottom row). Full size image ...
