Comparison of CT and MRI, with and without Contrast Enhancement, in the Detection of Brain TumorsMagnetic resonance imaging (MRI) as a clinical investigation became available in the early 1980s. Since then this method has proven to be a valuable additional diagnostic tool in the recognition and ...
By increasing the contrast of an image, it will be easy for analysing because of detailed information. This increase in contrast can be done by number of ways in image processing. This paper compares different methods of enhancement of brain MRI using histogram based techniques. 展开 ...
Our purpose was to compare prospectively the sensitivity of contrast-enhanced magnetisation transfer (MT) MRI and gradient-echo (GE) T1-weighted images in metastatic disease of the brain. We studied 52 patients with brain metastases, using conventional T1-weighted GE and MT spin-echo (SE) images...
慢性缺血性脑病变(Chronic Ischemic Brain Changes):长期缺血引起的脑组织损伤和萎缩。 骨髓炎(Osteomyelitis):骨和骨髓的炎症,MRI可以显示病灶和周围软组织的情况。 骨折线(Fracture Line):骨折处的裂缝或断口,在MRI上通常显示为异常信号的线条。 软骨损伤(Cartilage Damage):软骨的损伤或退变,MRI可以显示损伤的部位和...
Accelerating susceptibility-weighted imaging with deep learning by complex-valued convolutional neural network (ComplexNet): validation in clinical brain imaging. Caohui Duan, Yongqin Xiong, Kun Cheng, Sa Xiao, Jinhao Lyu, Cheng Wang, Xiangbing Bian, Jing Zhang, Dekang Zhang, Ling Chen, Xin Zhou...
A phenomenon known as magnetization transfer (MT) is thought to provide the primary source of contrast in NM-MRI, due to the increased contrast found with MT preparation of NM-MRI pulse sequences. MT contrast results from the interaction and exchange between water protons and the protons ...
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...
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
Superparamagnetic iron oxide nanoparticles (SPIONs) are widely investigated and utilized as magnetic resonance imaging (MRI) contrast and therapy agents due to their large magnetic moments. Local field inhomogeneities caused by these high magnetic moment
