1) signal intensity rate
信号强度比值
2) signal intensity ratio
信号强度比
1.
The signal intensity ratios(SIR,signal intensity at opposed-phase over signal intensity at in-phase) were calculated and compared among these conditions.
方法:回顾分析本院126例脊柱病变患者,包括31例恶性椎体肿瘤、38例急性椎体良性压缩性骨折、8例血管瘤、26例终板退变、18例局灶性骨髓脂肪变性及5例脊柱感染,计算各种病变正反回波的信号强度比(反相位/正相位,SIR),并对各组病例作对比和分析。
2.
ObjectiveTo explore the accuracy and clinical value of the MRI quantitative diagnostic,which are liver / muscle signal intensity ratio and T2 values in vitro iron concentration and liver iron deposition.
目的利用MRI肝脏/肌肉信号强度比值及肝脏T2值测定技术,探讨体外铁浓度及肝脏铁沉积的MRI定量诊断的准确性及临床应用价值。
3) contrast of the light signal intensity
光强信号对比度
4) correlated signal intensity ratio
相关信号强度比
5) satio of mixing signal
信号比值
补充资料:等信号强度
等信号强度
磁共振成像术语。磁共振成像中,与参照结构信号强度值相当的结构的信号强度,即与参照结构信号亮度近似的信号。MRI中的信号强度值为一无量纲值,在不同设备、不同场强、不同次扫描中的信号强度值是随机的。因此,通常只作信号强度的定性判断,不作定量比较。
