当一位疑似脑炎患者的脑脊液抗体检测阴性时,临床该如何避免漏诊?近年来随着抗体检测技术的革新与实验室诊断能力的提升,发病率已与感染性脑炎不相上下。然而,该疾病的诊断依旧困难重重。一方面,部分医务人员对其认知不足;另一方面,临床症状极易与精神疾病混淆,造 ...
This is an important study that combines replications of findings and novel detailed MRI investigations to assess the impact of environmental enrichment and maternal behavior on mice brain structure ...
Multiple sclerosis (MS) is a demyelinating disease that affects the central nervous system (CNS) and is characterized by the presence of CNS lesions. Volumetric measures of tissues, including lesions, ...
On T1- and T2-weighted MRI scans with complete suppression on FLAIR, as well as on diffusion-weighted images, a fluid-intensity lesion can be seen. A definite communication with the subarachnoid space ...
OUR resident specialist and NHS GP, Dr Zoe Williams, shares her expert advice. Today, Dr Zoe helps a reader who is worried an MRI might have affected their hip. Q) I HAVE got metal hip re… ...
The segmentation of brain tissue in MRI is valuable for extracting brain structure to aid diagnosis, treatment and tracking the progression of different neurologic diseases. Medical image data are ...

这篇研究通过多角度扫描和定量MRI(qMRI)技术,首次在人体离体软骨中验证了T2 弛豫时间可分解为方向无关的各向异性(R2a )和同性(R2i )组分。研究发现R2a 在退变软骨表层显著降低,且与胶原网络各向异性(PLM)和生物力学相移相关,为早期骨关节炎(OA)诊断提供了新视角。
来自多学科团队的研究人员通过定量MRI技术,探究了骨骼肌生物标志物 (T2值、CSA)与主观运动强度 (RPE)的关联。研究发现运动后T2值变化率 (T2* PC-post/pre)与RPE显著相关 (ρ=0.45,p<0.01),随机森林分析证实其预测价值,揭示了T2*值变化反映代谢应激的特异性,为无创评估运动负荷提供新思路。
Clinica can process any BIDS-compliant dataset with a set of complex processing pipelines involving different software packages for the analysis of neuroimaging data (T1-weighted MRI, diffusion MRI ...
Bone health. Weighted vest use has the potential to minimize bone mass loss while losing weight; that’s key to reducing the risk of fracture in older adults, says Kristen Beavers, Ph.D., MPH, RD, a ...
Accurate segmentation of the prostate in T2-weighted MRI is critical for effective prostate diagnosis and treatment planning. Existing methods often struggle with the complex textures and subtle ...
