Deep Learning Enables Reduced Gadolinium Dose for Contrast-Enhanced Brain MRI (Journal of Magnetic Resonance Imaging 2018) 这是一篇医学图像增强的论文,介绍了研究人员正在使用人工智能来减少MRI检查后留在体内的造影剂的剂量。 提出背景 钆(gá,gadolinium)是一种用于对比材料的重金属,可增强MRI上的图像,作为一...
During an MRI exam, the leads used with these devices, implanted in the body of the patient, act as an electric antenna potentially causing a large amount of energy to be absorbed in the tissue, which can lead to serious heat-related injury. This study presents a novel lead design that ...
Fig. 1: Prototype of a low-cost low-power and shielding-free brain ultra-low-field (ULF) magnetic resonance imaging (MRI) scanner with homogenous 0.055 Tesla magnetic field and small 5 Gauss fringe field. aWith ~2 m2footprint and no radiofrequency/magnetic shielding cages, the scanner can ...

Chapter 20 How MRI Makes the Brain Visible Denis Le Bihan 20.1 Progress of Imaging to Investigate the Anatomy of the Brain It is fair to say that medical imaging started with Roentgen (1896), who got the first Nobel Prize in Physics in 1901 for the discovery of ...
it remains unknown which anatomical site of stimulation [170] should be used for individual patients. Even if an optimal target for an individual patient were identified, ensuring accurate electrode placement, especially in areas with poor intrinsic MRI contrast, such as the thalamus, remains challeng...
with contrast-enhanced T1 MRI. Indeed, MRgFUS has been widely used to enhance anti-cancer drug delivery to pediatric brain tumors in mice [87] or polymeric nanoparticles in healthy rats [35,88]. One concern with FUS BBB opening is the need to titrate the energy of FUS and the dose of...
Background: Incidental findings are a well-known complication of imaging studies done for both diagnostic and research purposes. Little is known about the rates and types of incidental findings found on brain MRI in patients with HIV infection, who may b
(MRI) contrast characteristics as Cerebrospinal Fluid (CSF), that is they appear hypointense (dark) on T1-weighted (T1) and hyperintense (bright) on T2-weighted images (T2)1,2. They appear as small 3D tubular structures that, depending on the viewing plane, are linear or round, with a ...
