Three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) image inMRI has recently been developed to detect high concentrations of protein orhemorrhage. Other articles have previously reported that half of patients with idiopathic sudden sensorineur...
high signal with water suppression 因为水的信号比你希望看到的组织结构的信号强得多,所以需要抑制水的信号。 链接中的 medcyclopaedia.com 看起来是 GE 的一个网站,里面的好东西不少。 Reference: http://www.medcyclopaedia.com/library/topics/volume_i/w/water_suppression.aspx 16...

Imaging of human brain activity at 0.15 T using fluid attenuated inversion recovery (FLAIR) pulse sequences A 34% change in signal intensity correlated with visual stimulation was observed in the occipital lobes of three normal volunteers examined with MRI at 0.1... Joseph,V.,Hajnal,... - 《...
Subsequent brain magnetic resonance imaging (MRI) on June 1 revealed pronounced abnormal T1 and T2 signal in the corpus callosum and the bilateral white matter (Fig. 3). On June 9, the re-examination of the brain MRI revealed a notable reduction in the size of the lesions. A chest CT ...
lack of histological validation on the plaque is a common limitation in HRMRI studies, although preliminary studies have demonstrated a high level of agreement between MRI-defined plaque signal features and histology8,21. Fourth, given the young age, relatively low percentages of risk factors, the ...
signal intensity of vessel wall is less than that of the pituitary infundibulum (Fig. 2); and grade 2, strong enhance- ment, the signal intensity of contrast enhanced vessel wall is similar to or greater than that of the infundibulum (Fig. 3). The enhancement was regarded as ...
The objective of this study was to compare the images obtained with a new post-processing technique with conventional Inversion Recovery (IR) sequences both on healthy volunteers and on patients with neuronal migration disorders. The post-processing images were obtained by means of Proton Density and...
