<span>MR‐assisted PET</span> respiratory motion correction using <span>deep‐learning</span> based <span>short‐scan</span> motion fields Open
Purpose We evaluated the impact of PET respiratory motion correction (MoCo) in a phantom and patients. Moreover, we proposed and examined a PET MoCo approach using motion vector fields (MVFs) from a deep‐learning reconstructed short MRI sc…

Magnetic resonance safety assessment of a new trend: magnetic eyelashes Open
One type of cosmetic that has gained recent popularity is the magnetic false eyelash. Some of these magnetic eyelashes are placed onto magnetic eyeliner applied to eye lids, while others come in pairs and clamp around the natural eyelashes…

Dual-Imaging Modality Approach to Evaluate Cerebral Hemodynamics in Growth-Restricted Fetuses: Oxygenation and Perfusion Open
Objective: To evaluate a dual-imaging modality approach to obtain a combined estimation of venous blood oxygenation (SνO2) using susceptibility-weighted magnetic resonance imaging (SWI-MRI), and blood perfusion using power Doppler ultraso…

Quantitative Flow Imaging in Human Umbilical Vessels In Utero Using Nongated 2D Phase Contrast MRI Open
Background Volumetric assessment of afferent blood flow rate provides a measure of global organ perfusion. Phase‐contrast magnetic resonance imaging (PCMRI) is a reliable tool for volumetric flow quantification, but given the challenges wi…

Mri Methods For Imaging The Feto-Placental Vasculature And Blood Open
Fetal magnetic resonance imaging (MRI) in recent times has become a well-established adjunct to ultrasound (US) in routine clinical prenatal care and diagnostics. The majority of fetal MRI is restricted to T2-weighted scans, where the diag…

OC21.02: Estimation of oxygen saturation, blood flow and blood perfusion in the fetal brain of normally grown fetuses using ultrasound and <span>MRI</span> techniques Open
To estimate blood oxygen saturation and blood flow in the fetal brain using ultrasound (US) and magnetic resonance imaging (MRI) techniques. Fetal brain venous blood oxygen saturation was calculated in 39 normally grown fetuses using MR su…
