Toward Inter‐Sonication Monitoring of Skull and Brain Temperatures in Transcranial MRgFUS Using a 3D Stack‐of‐Spirals Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an MRI approach for simultaneous skull and brain temperature monitoring between sonications in transcranial MR‐guided focused ultrasound (MRgFUS) surgeries. Methods A 3D stack‐of‐spirals dual‐echo ultra‐short TE (UTE) sequence incorporating fat suppression, spiral deblurring, trajectory measurement, and B1 correction was ...

Comparison of screening strategies for prevalent vertebral fractures in South Korea: vertebral fracture assessment vs. spine radiography

BMC Musculoskeletal Disorders, 2018
Background Vertebral Fracture Assessment (VFA) is a useful tool to detect the vertebral fracture (VF) with low cost and radiation exposure. We aimed to compare screening strategies including VFA and spine radiography (X-ray) for detecting VF in terms of ...

Deep Learning Improves Robustness of Voxelwise Kinetic Modeling for Hyperpolarized Carbon‐13 MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate whether deep learning improves the robustness of voxelwise kinetic parameter estimation from hyperpolarized (HP) 13C MRI compared with nonlinear least‐squares (NLLS) fitting. Methods A hybrid neural network (NN) was trained on synthetic pyruvate/lactate time courses generated from an open‐system two‐compartment HP 13C ...

Prognostic impact of visceral and subcutaneous fat area in stage I-III colon cancer patients with cachexia: a population-based multicenter study

Frontiers in Nutrition
BackgroundAdipose tissue reduction is one of the features in patients with cancer cachexia. However, it remains unclear whether visceral fat area (VFA) and subcutaneous fat area (SFA) contribute differently to the progression of cancer cachexia in colon ...

Intergenotype differences in VFA for UCP1 -3826A/G.

, 2013
For each 3-month window, the means and standard errors of the VFA in the 3 genotype groups are shown. Average outdoor temperatures in the second month of each 3-month window are shown with a gray broken line.

p‐Brain: A Modular Open‐Source Framework for Automated Quantitative DCE‐MRI of Cerebral Perfusion, Microvasculature, and Blood–Brain Barrier Permeability

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT We present p‐Brain, a modular, open‐source framework for reproducible, automated quantitative DCE‐MRI at scale. Rather than a fixed pipeline, p‐Brain is built from interchangeable stages (ingestion, T1/M0$$ {T}_1/{M}_0 $$ fitting, vascular and tissue ROI extraction, signal‐to‐concentration conversion, kinetic modeling, and quality control ...

Association of visceral adiposity and clinical outcome among patients with aldosterone producing adenoma

BMJ Open Diabetes Research & Care, 2020
Introduction Primary aldosteronism (PA) is a common form of secondary hypertension that has significant cardiovascular events and increased prevalence of metabolic syndrome and diabetics. Although plasma aldosterone concentration is positively correlated

Incomplete Spoiling Correction for 3D T1$$ {T}_1 $$ Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Assess the impact of incomplete spoiling and spatial saturation on T1$$ {T}_1 $$ mapping using the variable flip angle (VFA) spoiled gradient recalled echo sequence (SPGR). Develop a correction for incomplete spoiling that results in an accurate estimate of T1$$ {T}_1 $$, essential for quantitative MRI applications.
