including tumors, that exhibit increased signal intensity. However, a single CE-MRI image does not capture the dynamics of contrast flow through the tumor microenvironment. While the signal intensity on CE-MRI is directly proportional to both MVD and GBCA concentration...
磁共振动态增强(dynamic contrast-enhanced magnetic resonance imaging,DCE-MRI) DCE-MRI是一种功能成像,可以反映肝脏血流动力学改变,后处理后得到的多个半定量及定量参数,可以从不同角度反映肝脏血流灌注、血管通透性等微循环情况,从而有望...
Multiparametric MRI of the prostate is now recommended as the initial diagnostic test for men presenting with suspected prostate cancer, with a negative MRI enabling safe avoidance of biopsy and a positive result enabling MRI-directed sampling of lesions. The diagnostic pathway consists of several step...
without intravenous contrast and relies 10:33 on blood bringing with it signal these 10:37 can be shown just as a stack of very 10:40 thin images and because there is little 10:42 background for the vessels to be 10:45 localized against it can be difficult to 10:47 know exactly where...
FIG. 4. An illustrative example of the benefit of our deep attention fully convolution network (DAFCN) compared with DSFCN without attention gate, (a1) shows the original CT image in transverse plane. (a2) shows corresponding manual contour, (a3) shows the generated synthetic magnetic resonance...
Non contrast versus contrast enhanced MRI of the great thoracic vessels in pediatric congenital heart disease: A quantitative and qualitative analysisNC-MRA produced similar and comparable measurements of the thoracic arteries with superior image quality when compared to contrast- enhanced MRA in pediatric...
had a correlation of 0.52 ± 0.01 and 0.50 ± 0.01 (P < .001). There were notable correlation differences (P < .001) between the BPE determined with the four methods. Among the four quantitation methods, method D offered the highest accuracy for distinguishing women with versus without anti...
