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 ...
Compared to the transverse one, this copious fat did not allow the pericardium to be visualized in the axial plane (Fig. 1). Fig. 1 (A) A representative MRI image of the heart showing heart length (HL) and heart base width (BW) measurements in millimeters. (B) A representative axial ...
Combining longitudinal MR imaging and finite strain theory, this study aimed to provide new insights into normal brain development through a biomechanical framework. Thirty-three normal infants were longitudinally imaged using MRI from 2 weeks to 1 year of age. Voxel-wise Jacobian determinant was ...

An increase in extra-axial cerebrospinal fluid volume in autistic individuals between the ages of 6 months and...
The same problem occurs in axial scans of the face (compare with Fig. 36.2b and Fig. 36.2c ). If a case of chronic sinusitis is suspected, it is very important to check whether the semilunar hiatus is open. It represents the main channel for discharging secretions of the paranasal ...
The CBIR framework was constructed on a per-image basis; that is, each MR volume was separated into slices along the axial axis and underwent image resizing and Z-score normalization in the same manner with the training of the feature decomposing network. By applying the trained feature decompos...
In 86 MRI studies in 68 children who showed enhancing intracranial lesions, lesion conspicuity on postcontrast FLAIR imaging was compared with that on postcontrast T1-W imaging for all lesions ( n=107), intra-axial lesions ( n=40), or extra-axial lesions ( n=67). Results:The normally ...

(The images below are examples of hydrocephalus ex vacuo and NPH from MRI.) Axial T2-weighted magnetic resonance image of the brain in a patient with hydrocephalus ex vacuo. Note the enlarged ventricular system and noticeable sulcal atrophy. View Media Gallery Axial T2-weighted magnetic resonance...
T1- weighted and proton density-weighted images [transmission time (TR), 2500; echo time (TE) 15/90] were acquired in the axial plane. In addition coronal T2-weighted images (TR 600, TE 1.5) were obtained. Brain Phe concentrations were deter- mined by localized 1H spectroscopy applying ...
