Disclosed are approaches to non-invasively characterize a tumor or other lesion in a region of interest (ROI) based on various analyses of magnetic resonance imaging (MRI) data. The MRI data may correspond to ultrafast dynamic contrast enhanced MRI (DCE-MRI) and high spatial resolution DCE-MRI scans, and diffusion-weighted MRI (DW-MRI) scans of the ROI. Vasculature metrics may be determined, and tumor-associated blood flow velocity and/or tumor interstitial pressure may be obtained using the vasculature metrics as inputs to a computational fluid dynamics model. A combination of morphological vascular metrics and functional vascular metrics may be used to characterize the tumor. Malignancy, aggressiveness, treatment response, and other features of tumors or other lesions, in the breast or other regions of a patient, may be characterized through disclosed analyses of MRI data.

Characterization of lesions via determination of vascular metrics using MRI data

A photograph holder comprising a base sheet of material from the surface of which four tabs protrude, two bottom tab means facing upwardly and having tabettes formed by notches therein and suitable for representing fingers of two upturned hands and two side tab means facing inwardly toward each other in combination with a second piece of material which can be a photograph disposed between said base piece and all, or at least one, of said tabs.
