Gadopentetic acid 是一种顺磁性造影剂，通常通过静脉内注射 (i.v.) 的方式用于 DCE-MRI 研究。

Gadopentetic acid (Gd-DTPA) is an paramagnetic contrast agent commonly implemented by a bolus intravenous injection (i.v.) in Dynamic contrast-enhanced MRI (DCE-MRI) studies.

The initial concentration of Gadopentetic acid (Gd-DTPA) in the plasma ([Gd-DTPA0]) is an important parameter for DCE-MRI.?[Gd-DTPA0] is related to the administered bolus dose and varies with subjects.?A bolus of 0.025 mmol/kg Gd-DTPA offers shorter acquisition time and less exposure of subjects, with a half-life of 37.3 mins, a mean residence time of 53.8 mins, and an AUC of 3.37 ± 0.47 mmol/min/L.
