Brain Pulsation Imaging Using Non‐Balanced Steady‐State Free Precession With 3D‐EPI Readout

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To present a new, fast MR imaging method for visualization and quantification of pulsatile displacement in brain tissue and fluid. Methods The natural phase‐contrast of non‐balanced steady‐state free precession combined with careful tuning of the intrinsic spoiler gradients is harnessed to measure displacement along specific physical ...

ASL 4D MRA Intracranial Vessel Segmentation With Deep Learning U‐Nets

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose a spatio‐temporal U‐Net based network (4DST) that exploits both spatial and dynamic information while avoiding memory‐intensive 4D convolutional layers for ASL‐based non‐contrast enhanced 4‐dimensional MR angiography (4D MRA) vessel segmentation.

Acute hemichorea‐hemiballism as the initial sign of cortical cerebral infarction: A case report

open access: yesNeuroprotection, EarlyView.
Abstract Hemichorea‐hemiballism is classically associated with the contralateral basal ganglia, particularly involving the putamen and subthalamic nucleus, whereas cortical involvement remains a rare etiology. In this case, we present a patient with acute hemichorea‐hemiballism secondary to multiple cortical infarcts demonstrated by neuroimaging.

Prenatal Exome Sequencing Identifies Dual Maternal‐Fetal Diagnosis of HbF Mission Bay, a Novel HBG2 Variant Associated With Methemoglobinemia, Hypoxia and Hemolytic Anemia

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Prenatal exome sequencing (ES) can establish rare genetic diagnoses in a fetus but may also lead to occult genetic diagnosis in a biological parent. We present a case of dual fetal and maternal diagnosis by prenatal ES, in a fetus with unexplained anemia and in a pregnant patient with sickle cell disease (SCD) and recurrent unexplained hypoxia.

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

The Expanding Role of Gene Sequencing in Shaping Fetal Therapies: Clinical and Ethical Considerations

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and
