Radiocontrast Media Allergy

Radiocontrast media allergy refers to an adverse reaction some individuals experience after receiving a special dye used in imaging tests, like CT scans or MRIs. This dye helps doctors see internal structures more clearly. In cases of allergy, the immune system mistakenly identifies the dye as harmful, leading to symptoms such as hives, itching, or breathing difficulties. While true allergies are relatively rare, it’s important for patients to inform their doctors about any previous reactions to contrast dyes to ensure safe imaging practices and to consider alternatives if necessary.
