Classification of HARM by location and severity. Definitions used for HARM classification.

A 74-year-old man who underwent off-pump CABG. A, Baseline FLAIR obtained before surgery. B, Postgadolinium scan. Gadolinium was administered 20 hours after surgery, and 3T MR imaging was performed 20 hours later. Postgadolinium FLAIR shows enhancement throughout the subarachnoid space (severe sulcal and background HARM). The CSF in the ventricles appears gray (mild/moderate ventricular HARM). Gadolinium enhancement is also seen in the eye. C, DWI obtained after surgery. Patient had 4 DWI lesions.

An 86-year-old man who underwent CABG. A, Baseline FLAIR performed before surgery. B, Postgadolinium FLAIR. Gadolinium was administered 23 hours after surgery, and the 1.5T MR imaging was obtained 27 hours later. Postgadolinium FLAIR shows bright enhancement in the right frontal and left parietal subarachnoid space (arrows, severe sulcal HARM). C, Postoperative DWI. The patient had 6 DWI lesions.
