Background: The infratentorial compartment is cardinal for multiple sclerosis (MS) diagnosis. T2-weighted (T2) and proton density–weighted (PD) magnetic resonance imaging (MRI) can visualize infratentorial lesions, but only suboptimally. Objective: To combine PD and T2 for better lesion assessment. Methods: T2 and PD from 35 cases were averaged to form “PT2” images. Two raters counted infratentorial lesions and qualitatively assessed their conspicuity. Results: PT2 showed 244 infratentorial lesions, of which 94% and 74% were seen in PD and T2. PT2 received higher grades for image quality and lesion conspicuity ( p < 0.001 for all comparisons). Conclusion: PT2 could improve our ability to diagnose and monitor MS.
