Imaging Venous Transit Time and Blood–Brain Barrier Permeability of the Deep Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Imaging of venous vessels with advanced pulse sequences allows the assessment of important hemodynamic parameters. Previous work has measured venous transit time (VTT) and blood–brain barrier (BBB) water permeability in cortical tissue.

DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Prenatal Diagnosis and Management of Kaposiform Hemangioendothelioma With Kasabach–Merritt Phenomenon: Imaging Features and First Experience With Maternal Sirolimus Therapy

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To describe the prenatal diagnosis, evolution, and perinatal management of kaposiform hemangioendothelioma (KHE) complicated by the Kasabach–Merritt phenomenon (KMP), and to report the first documented use of maternal sirolimus therapy (MST) in this setting. Methods We retrospectively reviewed four fetuses with a prenatal soft‐tissue

Kaposiform hemangioendothelioma: Diagnosis and treatment

Pediatric Investigation, EarlyView.
Vascular endothelial growth factor‐C (VEGF‐C)/vascular endothelial growth factor receptor‐3 (VEGFR‐3) and angiopoietin‐2 (Ang‐2)/tyrosine kinase with immunoglobulin‐like and EGF‐like domain 2 (TIE2) signaling pathways play an important role in lymphangiogenesis.
