T1加权成像（T1-weighted imaging）是MRI扫描的一种，它通过对组织中的质子进行特定的处理以提供对组织结构和解剖的详细信息。在T1加权成像中，脑脊液和脂肪组织呈现为黑色，而大脑灰质和白质呈现为浅灰色或白色。然而，T1增强成像（T1-weighted contrast-enhanced imaging）是T1加权成像的一个特殊版本。在T1...
T2-weighted scans are most typically utilized in MRI to distinguish fat from water, with water having a brighter contrast than fat. Negative contrast enhancement and darker images of the regions of interest are possible with T2 contrast agents. In the late 1970s, dextran-coated iron oxide nanopa...

T1-weightedoptimal doseNowadays magnetic resonance imaging (MRI) has been commonly used in many indications. Concurrent development of MRI contrast agents has aided the rapid expansion and increased clinical efficacy. The use of contrast agents can improve lesion detection and characterization. With the...
We present an ultrahigh resolution in vivo human brain magnetic resonance imaging (MRI) dataset. It consists of T1-weighted whole brain anatomical data acquired at 7 Tesla with a nominal isotropic resolution of 250 μm of a single young healthy Caucas

The 3D T1-weighted brain image inputs were first resampled into a grid of 256 × 256 × 256 voxels with an isotropic spatial resolution of 1 × 1 × 1 mm using the mri_convert routine in FreeSurfer33. From the resampled complete images, coronal slices around the MTL we...
