Ferumoxytol-enhanced MR venography for mapping lower-extremity venous networks and evaluating varicose veins in patients with diabetes

Ultrahigh-Resolution Visualization of Vascular Heterogeneity in Brain Tumors via Magnetic Nanoparticles-Enhanced Susceptibility-Weighted Imaging

“…Multiple imaging sequences, including contrast-enhanced T 1 -weighted imaging (CE-T 1 WI), perfusion-weighted imaging (PWI), and time-of-flight magnetic resonance angiography (TOF-MRA), can directly or indirectly assess the characteristics of tumor vasculature. For instance, CE-T 1 WI not only delineates the detailed morphology and boundary of the tumor, but also aids in identifying tumor vascular density and BBTB permeability. − PWI is capable of evaluating the hemodynamic characteristics of the tumor, encompassing parameters such as blood flow and vascular permeability . However, these sequences merely provide an indirect assessment of the tumor’s microvascular density and functionality .…”
