Unleashing the Potential of Generalist Segmentation Foundation Models for Biomedical Image and Video Analysis

iRADIOLOGY, EarlyView.
Generalist segmentation models such as SAM and SAM2 show promise in biomedical imaging but face challenges such as domain shift and ambiguous boundaries. Future efforts should focus on specialized adaptation for clinical translation. Imaging data are derived from the public datasets AbdomenAtlas and BraTS19.

Comparative Analysis of Four Matrix Dilution Methods for Eliminating IgM Paraprotein Interference in Prealbumin and Uric Acid Assays: Based on Two Case Reports

Journal of Clinical Laboratory Analysis, EarlyView.
IgM paraproteins can cause significant interference in prealbumin (PA) and uric acid (UA) measurements, leading to falsely abnormal results. We systematically compared four dilution methods to eliminate this interference. Dilution with the PA reagent (containing PEG) effectively restored accurate PA results.

An Evaluation of Vital Signs in Intubated Neonates Undergoing Lung Point‐of‐Care Ultrasound in the Neonatal Intensive Care Unit

Journal of Clinical Ultrasound, EarlyView.
Lung POCUS exams do not appear to affect the cardiorespiratory stability of intubated neonates, suggesting that lung POCUS can be performed without affecting cardiorespiratory stability within the NICU setting on critically ill neonates for diagnostic purposes.

Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

Pulsatility Assessment of Cerebral Perforating Arteries Using Submillimeter‐Resolution Dual‐VENC Phase‐Contrast MRI at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dysfunction of cerebral perforating arteries is a major contributor to cerebral small vessel disease. Developing a reliable MRI technique for assessing cerebral perforating arteries on widely accessible 3T systems would be advantageous.

Clinical Validation of a Fast MRI Method to Evaluate Brain Vascular and Parenchymal Abnormalities in Sturge‐Weber Syndrome

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sturge‐Weber syndrome (SWS) is a rare neurocutaneous disorder associated with venous capillary malformations, atrophy, and calcifications. Longitudinal imaging is limited by risks of sedation and gadolinium exposure in children.

Analysis of Upper Airway Morphology Using Four‐Dimensional Dynamic MRI With Active Deep Learning‐Based Automatic Segmentation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Upper‐airway morphology changes during breathing can be captured with cine 4D MRI. Active‐learning nnU‐Net reduces manual labeling while maintaining accuracy. Purpose For automatic upper airway segmentation on free‐breathing cine 4D MRI using active learning and quantifying dynamic changes under two mouth positions.

Quantitative Real‐Time MRI for the Assessment of Gastric Motility

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

Longitudinal 4D Flow MRI‐Derived Wall Shear Stress in Patients With an Abdominal Aortic Aneurysm

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 4D flow MRI‐derived parameters such as wall shear stress (WSS) may improve abdominal aortic aneurysm (AAA) progression prediction. Validation of this biomarker is needed, but longitudinal data are lacking. Purpose Investigate longitudinal WSS changes and associations with AAA morphology. Study Type Prospective.
