Introduction:

the use of magnetic resonance contrast media is a necessity. In order to obtain a more effective image, the most ideal contrast should be used to minimize adverse reactions and deposition in tissues and target organs. Due to the repeated use of these contrasts in patients with oncologic follow-up of brain tumors, contrast deposits have been observed in the brain.

Objective:

to study the characteristics of gadolinium-based contrast media and their use in magnetic resonance imaging.

Methods:

a documentary review was carried out, theoretical methods were used for the theoretical references of the subject, the interpretation of the documentary review and the progression of the information in the articles.

Results:

the toxicity of gadolinium-based contrast media depends on several factors and the occurrence of mild and severe adverse reactions with their use can be avoided.

Conclusions:

for the use of gadolinium-based contrast media, the benefit/risk ratio should be assessed, this premise should coincide with the real need for an effective diagnosis and prognosis (or both). The objective is to administer the lowest possible dose, which is related to the maximum effective enhancement time.
