Simple Summary Brain metastases affect up to thirty percent of the adult cancer population. One of the treatment options is stereotactic radiosurgery (SRS). To better understand SRS …
Chronic active multiple sclerosis lesions, also referred to as rim+ lesions, are characterized by a hyperintense rim observed at the lesion's edge on quantitative susceptibility maps …
Abstract Background and Purpose We investigated the effects of aging, white matter hyperintensities (WMH), and cognitive impairment on brain iron levels and cerebral oxygen …
Purpose To develop a method for rapid sub‐millimeter T1, T2, T 2* T _2^ ∗, and QSM mapping in a single scan using multi‐contrast learned acquisition and reconstruction …
