The Gd-DTPA strong paramagnetic for DJASONICS/MT NME imaging showed increased T1 signal potential value significantly both in vitro at lower concentration (0.01 mmol/L) and when the Gd-DTPA (0.1mm/kg) injected intravenously for rabbit kidney imaging.

• Gd-DTPA双葡甲胺盐溶液经DIASONICS/MT磁共振影象仪体外增强试验和兔iv(0.；1mmol/kg Gd-DTPA)肾扫描显象；均能测到Gd-DTPA有明显增强T_1信号值效果。
