Although adverse reactions following contrast medium (CM) application occur regularly
in routine, radiologists are in most cases not familiar with the clinical reaction
patterns. Therefore, the documentation in the patients' records is often inadequate.
Moreover, papers dealing with contrast medium induced side effects also reflect the
poor knowledge in this field. For example, the unspecific term “adverse CM reaction”
sometimes remains unclassified in the literature [
[1]
]. Furthermore, in the literature risks are mentioned which do not increase the risk
for an adverse reaction, and vice versa [
[2]
,
[3]
]. Beside the description of clinical symptoms, the reactions are often classified.
Due to the pathological nature, we can differentiate between type A and type B drug
induced reactions [
[4]
]. Type A reactions are predictable, common, and related to the pharmacological properties
of the drug. Type B reactions are hypersensitivity reactions (allergy and non-allergy)
that are unpredictable, uncommon, and usually not related to the pharmacological properties
of the drug. Adverse CM reactions are in more than 80% type A, and in less than 20%
type B reactions [
