[General adverse reactions to contrast agents. Classification and general concepts].

Area of Science:

• Radiology
• Pharmacology

Background:

• Intravenous contrast agents, including iodinated and gadolinium-based types, are increasingly used in diagnostic imaging.
• While generally safe, these agents can cause adverse reactions.
• Radiologists must be prepared to manage potential complications.

Purpose of the Study:

• To review the incidence and significance of adverse reactions to intravenous contrast agents.
• To highlight the importance of prevention and treatment strategies for radiologists.

Main Methods:

• Literature review of adverse events associated with iodinated and gadolinium-based contrast agents.
• Analysis of reaction severity and patient outcomes.
• Discussion of current management guidelines.

Main Results:

• Adverse reactions to intravenous contrast agents are uncommon.
• Most reactions are mild, but severe events can occur.
• Effective management protocols are essential for patient safety.

Conclusions:

• Radiologists require knowledge of contrast agent adverse reactions for optimal patient care.
• Proactive management and preparedness are key to mitigating risks associated with contrast-enhanced imaging.
