Mapping Amygdalar structural differences in Alzheimer's patients with 3T MRI

Background: Histological and in vivo MRI studies show that the amygdala is affected by Alzheimer’s Disease (AD) pathology; its shape is altered [1,2] especially in its medial aspect [3]. Aim: To assess in vivo local amygdalar changes in AD patients using high resolution MRI at 3 Tesla, and identify the involved nuclei. Methods: 19 AD patients (age 76±6 years, Mini Mental State Examination (MMSE...

MRI endoscopy at 3T

Introduction: Until now MRI could not perform traditional endoscopy from the viewpoint of an internal probe because localization depended entirely on the fixed external gradient system and was hence intrinsically locked to the laboratory frame-of-reference (FoR). A method for high-resolution MRI using active internal probes that utilizes the spatial properties of the probe itself, for MRI has b...

3t Body Mri

The inherent doubling in signal-to-noise ratio when compared to 1.5T provides unique opportunities for body MR imaging at 3T. The augmented SNR can be used to improve anatomic and/or temporal resolution and reduce breath hold time periods while preserving image quality. However, susceptibility, and chemical shift dispersion are also increased at 3.0T (scaling with field strength) and T1 and T2 ...

An MRI study of spatial probability brain map differences between first-episode schizophrenia and normal controls.

We created a spatial probability atlas of schizophrenia to provide information about the neuroanatomic variability of brain regions of patients with the disorder. Probability maps of 16 regions of interest (ROIs) were constructed by taking manually parcellated ROIs from subjects' magnetic resonance images (MRIs) and linearly transforming them into Talairach space using the Montreal Neurological...

Are there differences in brain morphometry between twins and unrelated singletons? A pediatric MRI study.

Twins provide a unique capacity to explore relative genetic and environmental contributions to brain development, but results are applicable to non-twin populations only to the extent that twin and singleton brains are alike. A reason to suspect differences is that as a group twins are more likely than singletons to experience adverse prenatal and perinatal events that may affect brain developm...
