2019年12月13日 · Nature Communications - Magnetic resonance imaging (MRI) is widely used to study the rat brain. Here, the authors provide standardized MRI brain templates and descriptive atlases for the...

2020年1月13日 · Barrière et al. combine both in vivo and ex vivo MRI images from 47 eight-week old male Wistar rats to create anatomical templates that distinguish between gray matter, white matter, and ...

In this international collaborative project, we seek to gather the rodent imaging community toward performing a rat fMRI multi-center comparison, within the same template as Grandjean et al. NIMG 2020.

Open access volumetric atlas of the Sprague Dawley rat brain. The delineations are defined in isotropic magnetic resonance (39 μm) and diffusion tensor (78 μm) images acquired ex vivo from an 80 day old male rat at the Duke Center for In Vivo Microscopy.

2020年4月24日 · This paper reports the development of a high-resolution 3-D MRI atlas of the Fischer 344 adult rat brain. The atlas is a 60 μm isotropic image volume composed of 256 coronal slices with 71 ...

2023年3月27日 · An accurate and automatic skull stripping tool for rat brain image volumes with magnetic resonance imaging (MRI) are crucial in experimental stroke analysis. Due to the deficiency of reliable rat brain segmentation methods and motivated by the demand for preclinical studies, this paper develops a new skull stripping algorithm to extract the rat ...

During MRI scan, all rats were anesthetized using inhaled isoflurane/O 2 (3% for induction and 1.5–2% for maintenance) and prostrated on a custom‐made holder to minimize head motion while respiration was monitored at a rate of 50 breaths per min.

2014年1月15日 · We present a novel method for automatically skull-stripping rodent brain MRI datasets. Our approach combines mathematical morphology techniques and graph-based segmentation. We evaluate performance using a T1-weighted rat dataset and a …

2019年12月13日 · Here, we present two rat brain MRI templates and their associated gray matter, white matter and cerebrospinal fluid probability maps, generated from ex vivo [Formula: see text]-weighted images (90 µm isotropic resolution) and in vivo T 2 …

2020年11月15日 · The aim of our study was to provide an MRI-based rat brain atlas that is free to use and easily available on-line or in paper version that can help scientists quickly identify at least the main cerebral structures in original MR images, without removing the skull layer, without brain image homogenization, and without overlying the corresponding ...
