Some uses for MRI with contrast are: 1. Assessing MS Contrast MRIs are a great way to track the progression of multiple sclerosis. MRI scans have transformed how radiologists diagnose MS, and are now the primary method doctors use to diagnose the condition, to the exclusion of other techniques...
其基本原理是实时定位最方便观察目的血管段的层面,系统将以1~2帧/秒的速度重复扫描,当肉眼观察到造影剂到达该处时,手动启动扫描(Go 3D)。 TRICKS--时间分辨的增强动力学成像(Time-Resolved Imaging of Contrast KineticS),能通过造影剂血液动力学进行全身的动态增强扫描。具有...
For all parameters of vision, recovery was similar regardless of location or length of abnormal enhancement. Abnormal contrast enhancement of the optic nerve is a sensitive (94%) finding in acute optic neuritis and is absent in unaffected or previously affected optic nerves. Although lesions ...

This contrast agent is therefore no longer used but manganese-enhanced MRI (MEMRI) using MnCl2 is still utilized for preclinical studies in mice with brain [19] or lung [20] model tumors. For safe use in the clinic, manganese complexes have been developed and the second manganese-based CA ...
Most MRIs are performed without a contrast dye because it isn't needed to get accurate results for the suspected problem. Also, certain patients (those who are pregnant as well as those with kidney disease) shouldn't get the contrast dye because of possible complications. What Is an MRI Scan...
摘要: PURPOSEThe purpose of this study was to synthesize, characterize and tailor the surface properties of magnetic nanoparticles with biocompatible copolymer coatings and to evaluate the efficiency of the resulting nanoconjugates as magnetic resonance imaging (MRI) contrast agents for liver imaging....
Hepatic MRI with SPIO: detection and characterization of focal liver lesions. A variety of parenterally administered iron oxides have been developed for contrast-enhanced MRI of the liver. Two different classes of iron oxides are cur... P Reimer,B Tombach - 《European Radiology》 被引量: 532...
For T2 MRI inactive PPy nanoparticles, paramagnetic polarons are block from water protons by strong “spin–spin” interactions between polarons. For PPy nanoparticles with weak T2 MRI contrast, above interactions are moderately reduced by catechol derivatives used in “partially complexed” method. Fo...
