钆(gá,gadolinium)是一种用于对比材料的重金属,可增强MRI上的图像,作为一种纵向弛豫造影剂(T1制剂),其作用主要使T1缩短,在T1加权图像上呈高信号。研究发现,经过某些类型钆检查的人体内残留了大量的金属。这种沉积的影响尚不清楚,但放射科医师正在积极主动地优化患者安全性,同时保留钆增强MRI扫描提供的重要信息。因此...
在医疗应用方面,钆-二乙烯二胺五醋酸(DTPA)的络合物,正好可以像X射线造影剂钡那样,作为MRI(磁共振成像诊断)的画面浓淡的调节剂来使用。也就是利用钆周围的水受到钆原子核磁场力矩的影响,显示出和没有受到影响的水性质不同这一点,使用对照画面,有利于病情的诊断。
The MRI procedure was conducted under sedation using propofol. After completion of the procedure, the patient showed decline in respiratory rate, scleral edema and diffuse wheezing. A diagnosis of GBCA-induced anaphylaxis was made. The patient was treated with epinephrine, antihistaminic (...

Gadolinium’s compounds are used for making phosphors for color TV tubes and solutions of its compounds are used as intravenous contrasts to enhance magnetic resonance imaging (MRI) for medical patients. While it has no known biological role, it is said to stimulate metabolism...
