This developed a morphometric assessment for functional evaluation of coronary stenosis with intravascular ultrasound and ultrasonic flow ratio in vessels with single stenosis; the results demonstrated ultrasonic flow ratio (UFR) has a good correlation with the Murray law‐based quantitative flow ratio (uQFR).

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

View Order With Arbitrary Center Echoes
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Kaposiform hemangioendothelioma: Diagnosis and treatment
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.

ABSTRACT Wheezing is a common respiratory symptom in infants and toddlers, and recurrent wheezing is a significant respiratory disorder affecting this age group. Given the multifactorial etiology of recurrent wheezing, clinical practice lacks standardized diagnostic and therapeutic protocols. Recent years have witnessed substantial progress in clinical
