QQ‐Based Oxygen Extraction Fraction (OEF) Mapping in Mouse Brain: Initial Experience

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Oxygen extraction fraction (OEF) is a vital biomarker of cerebral oxygen metabolism and tissue viability. A novel OEF mapping method, QQ, which combines quantitative susceptibility mapping (QSM) and quantitative blood oxygen level‐dependent (qBOLD) (QSM + qBOLD = QQ), has demonstrated promise in detecting disease‐related OEF ...

Whole‐Brain Cerebral Microvascular Pulsatility Imaging Using Dynamic pCASL MRI With Segmented Stack‐of‐Stars Golden‐Angle Radial Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an efficient dynamic pseudo‐continuous arterial spin labeling (pCASL) MRI technique for whole‐brain microvascular flow pulsatility imaging. Methods The proposed technique combines pCASL with a segmented stack‐of‐stars golden‐angle radial acquisition.

Prandial Effects on Intravoxel Incoherent Motion Quantification in the Liver

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of detecting prandial (i.e., meal) induced changes in microvascular flow in the liver, including changes in the spatial distribution of flow velocities, using intravoxel incoherent motion (IVIM) MRI. Methods Thirteen (n = 13) healthy volunteers underwent two liver MR exams: one preprandial after fasting and ...

Rotating Frame Spin‐Lock Cardiac MRI Method at 9.4 T Can Characterize Diffuse Fibrosis in Progressing Hypertensive Heart Disease in Mice

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to investigate the applicability of rotating frame spin‐lock continuous wave (CW) T1ρ and relaxation along a fictitious field with Rank 2 (RAFF2) methods complementary to native T1 and late gadolinium enhancement (LGE) for cardiac magnetic resonance imaging (CMRI) of diffuse fibrosis in mice with advancing hypertensive

Hemolytic Disease of the Fetus and Newborn: Fetal RHD Genotyping, Targeted Prophylaxis, and Prenatal Therapies

Prenatal Diagnosis, EarlyView.
ABSTRACT Hemolytic disease of the fetus and newborn (HDFN) remains a significant concern in prenatal care primarily caused by maternal alloimmunization against fetal red blood cell antigens, most commonly the D antigen. Noninvasive fetal RHD genotyping, used as a screening tool, enables targeted antenatal prophylaxis and has been implemented in several

Fetal Intracranial Hemorrhage: What to Tell Expecting Parents?

Prenatal Diagnosis, EarlyView.
ABSTRACT Fetal intracranial hemorrhage (ICH) is a rare but serious prenatal diagnosis, and counseling affected families remains challenging. In this narrative review, we summarize current evidence on the classification, epidemiology, etiology, diagnosis and neurodevelopmental outcomes of fetal ICH, with a primary focus on intraventricular hemorrhage ...
