Comparing Digital Reduction Guides and Free‐Hand Techniques for Predoctoral Crown Preparation Accuracy

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives Insufficient tooth reduction compromises crown longevity and aesthetics. This study aimed to determine whether digitally designed, 3D‐printed reduction guides improved crown preparation accuracy and efficiency for dental students compared to freehand preparation.

Cross‐Vendor Validation of Proton Density Fat Fraction and T1 Mapping Using a Combined Proton Density Fat Fraction—T1 Phantom

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background In chronic liver disease, fat and fibroinflammatory changes often coexist. However, their biomarkers, proton density fat fraction (PDFF) and T1, are typically assessed separately. Their reproducibility under mutual confounding remains unclear.

Optimization and Implementation of DRAM-Based Interleavers for Free-Space Optical Communication Beyond 100 Gbit/s

IEEE Access
Optical transmission links from low earth orbit (LEO) satellites to earth require interleaving to ensure reliable data transmission. With data rate requirements beyond 100 Gbit/s and channel coherence times in the millisecond range, the capacity of on ...

Characterization of Pulmonary Functional Abnormalities in Systemic Sclerosis Using Xenon MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Xenon MRI is increasingly used to evaluate patients with interstitial lung disease (ILD) and pulmonary hypertension (PH), both of which are common manifestations of systemic sclerosis (SSc). As such, Xe‐MRI may be suited to interrogate lung function impairment in SSc.

Cerebral Blood Transit in Sickle Cell Anemia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

Performance of Free‐Running Cardiac and Respiratory Motion‐Resolved Whole‐Heart 5D MRI in Congenital Heart Disease Patients Using a Gadolinium Enhanced Fast‐Interrupted Steady‐State Sequence

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The performance of 5D imaging in CHD has been previously demonstrated using ferumoxytol rather than gadolinium. Purpose To evaluate the performance of gadolinium enhanced 5D MRI relative to 2D and 3D MRI in CHD patients. Study Type Retrospective.
