We investigated vascular remodeling after stroke using MRI mean segment length (MSL) and vessel size index (VSI) measurement and correlate the results with measurements using Laser Scanning Confocal Microscopy (LSCM). We demonstrate that MRI MSL and VSI can detect the microvascular status of brain tissue with different ischemic damage. The MSL and VSI measured by MRI were highly correlated with LSCM histological measurements. Our data demonstrate that these MRI measurements can quantitatively evaluate microvascular remodeling after stroke.
