Comparison of MRI Sequences to Detect Ventriculitis

OBJECTIVE. The ability of different MRI sequences to depict characteristic findings suggestive of ventriculitis was compared.

CONCLUSION. The study comprised 20 brain MRI studies in 13 patients who had a final diagnosis of ventriculitis. Both diffusion-weighted imaging and FLAIR imaging were equally and highly sensitive for detecting intraventricular debris and pus—the most common MRI finding suggestive of ventriculitis. FLAIR imaging was superior to contrast-enhanced T1-weighted imaging for depicting ventricular wall abnormalities—a less common finding that also is suggestive of ventriculitis.
