胎儿侧脑室增宽是产前影像学检查中常见的中枢神经系统疾病,预后有正常到严重功能障碍不等。目前仍缺少与产后个体神经发育功能相关的胎儿预测标志物,增加产前诊断和临床管理的难度。磁共振成像(magnetic resonance imaging, MRI)技术的不断进步使得其在侧脑室增宽诊断、预后评估及病因探索等方面更加准确和可靠,对预后管理和产前咨询具有重要作用。但受MRI的潜在安全隐患及经济、技术等限制,MRI不作为产前影像学诊断的首选,超声和MRI对胎儿侧脑室增宽的测量结果和分级仍存在争议 ...

Blood pressure targets for prevention of cognitive decline in patients with diabetes and hypertension: Design of the Blood Pressure Control Target in Diabetes (BPROAD) Cognitive Study 高血压目标对于预防糖尿病和高血压患者的认知下降:BPROAD认知研究的设计

open access: yesJournal of Diabetes, Volume 15, Issue 12, Page 1041-1047, December 2023., 2023
Highlights The optimal blood pressure (BP) target in patients with type 2 diabetes mellitus (T2DM) for the management of cognitive decline remains unknown. The Blood Pressure Control Target in Diabetes (BPROAD) Cognitive Study was designed to determine whether intensive BP treatment (systolic BP <120 mm Hg) reduces risk of dementia and mild cognitive ...

Neonatal and long‐term outcomes of infants with congenital cytomegalovirus infection and negative amniocentesis: systematic review and meta‐analysis

open access: yesUltrasound in Obstetrics &Gynecology, Volume 61, Issue 2, Page 158-167, February 2023., 2023
ABSTRACT Objective Cytomegalovirus (CMV) DNA is detectable in the amniotic fluid collected by amniocentesis in cases in which the fetus has been infected. However, cases of congenital neonatal CMV infection with a negative amniocentesis result have also been reported in the literature.

Cortical Thickness in Dutch Police Officers: An Examination of Factors Associated with Resilience

open access: yesJournal of Traumatic Stress, Volume 33, Issue 2, Page 181-189, April 2020., 2020
Abstract Previous neuroimaging studies on resilience have generally compared resilience and psychopathology after stress exposure, which does not allow for conclusions regarding correlates specific to resilience. The aim of the present study was to investigate resilience‐specific correlates in cortical thickness and/or cortical surface area and their ...

1.5 T关节磁共振成像超导磁体的设计、制作与测试

open access: yes, 2017
磁共振成像(magnetic resonance imaging,MRI)是当今世界上最先进的医学影像技术之一,现阶段MRI技术正朝着成像质量更清晰、功能更强大、效率更高、个体化更强的趋势发展.与全身MRI设备相比,专科型MRI设备具有体积小、重量轻、成本低、病人舒适度高、成像质量高、功能更强等优点.但是关节专用超导MRI系统需要长度方向上被严格限制的超导磁体在160 mm直径球域(diameter sphere volume,DSV)内产生高均匀度的磁场.本文综合考虑了超导线用量 ...
