What do we do with prior Gadolinium "allergic-like" event?
If a patient has had a prior reaction to a gadolinium agent but is approved to have a repeat scan with gadolinium (see pretreatment policy https://medicine.yale.edu/diagnosticradiology/patientcare/policies/ in contrast manual) effort should be made to determine which contrast agent the reaction occurred with.
If unknown, Dotarem can be used. If with Dotarem, then Multihance should be used.
