Background The impairment of cognitive function is one of the core symptoms in schizophrenia, and the degree of recovery is closely related to whether patients are able to rejoin society successfully. Objective This study was to clarify the correlation between cognitive function and cerebral grey matter volume in schizophrenia.

A terminology (or coding system) is a formal set of controlled vocabulary in a specific domain. With a well‐defined terminology, each concept in the target domain is assigned with a unique code, which can be identified and processed across different medical systems in an unambiguous way.

Abstract Objectives Neonates with critical congenital heart disease (CCHD) are at risk for adverse early brain development and long‐term neurodevelopmental sequelae. Insulin‐like growth factor‐1 (IGF‐1) and insulin‐like growth factor binding protein‐3 (IGFBP‐3) are essential contributors to brain growth and maturation.

ABSTRACT Objective To determine the diagnostic accuracy of virtual autopsy using whole‐body postmortem ultra‐high field magnetic resonance imaging (MRI) at 7 Tesla (T), using a short T2‐weighted imaging (T2‐WI) protocol, compared with classical autopsy, for detecting structural abnormalities in small second‐trimester fetuses. Methods Thirty consecutive

Fetal and neonatal neuroimaging in twin–twin transfusion syndrome
ABSTRACT Objectives To describe the types of brain injury and subsequent neurodevelopmental outcome in fetuses and neonates from pregnancies with twin–twin transfusion syndrome (TTTS). Additionally, to determine risk factors for brain injury and to review the use of neuroimaging modalities in these cases.

The Research and Design of Coil Tuning Module in MRI [PDF]
在成像过程中,射频线圈的工作状态对成像质量影响很大。射频线圈的共振频率和阻抗随着样品的放入会发生改变,造成信噪比和Q值的下降影响成像的质量,而产生的信号反射严重时会损坏功率模块,所以每次成像前后都需对射频线圈进行调谐。传统的调谐采用的是手动操作、上位机显示的方法,操作不便捷,速度较慢。设计一个便于观察的手动调谐检测装置是一个改进的方案,而使用自动调谐不仅不需要人的参与,而且对调谐速度和精度都有一个大的提升。 本文首先回顾了核磁共振的历史和发展,对核磁共振现象及磁共振成像机理进行了阐述 ...

目的探讨磁共振全身弥散成像对骨转移性病变的诊断价值。方法32例恶性肿瘤患者行全身磁共振弥散成像检查。使用反转恢复平面回波弥散序列分5段进行全身扫描。结果反转恢复平面回波弥散序列成功进行了全身磁共振弥散成像。重建出的最大密度投影像图像均一,清晰。32例恶性肿瘤患者中19例患者检出了多发骨转移灶;7例患者为单发转移灶;2例淋巴瘤表现为骨髓信号增高;1例为多发骨髓瘤;3例假阴性。结论全身磁共振弥散成像对骨转移性病变是一种有效的检出方法。

在2018年的全球肿瘤流行病统计数据(GLOBOCAN)报告中,乳腺癌的发病率位居女性恶性肿瘤的首位[1]。1991年开始,核磁共振成像(MRI)被认可作为乳腺癌的辅助诊断手段[2]。以往,MRI平扫及增强扫描对乳腺癌显示出了诊断的高敏感性[3-7]。近年来,动态增强核磁共振扫描(DCE-MRI)和弥散加权成像(DWI ...
