Ferumoxytol-Enhanced Cardiac Magnetic Resonance for Delineation of Hyperacute Intramyocardial Hemorrhage With Ex Vivo Validation

Arutyun Pogosyan, Caroline M. Colbert, Mostafa Mahmoudi, Mary Keushkerian et autres

OBJECTIVES: Intramyocardial hemorrhage (IMH) is the most severe form of injury associated with reperfusion therapy during acute myocardial infarction (AMI). Although T2*-weighted cardiac MRI is regarded as the reference standard for IMH detection, its application is limited in the hyperacute phase. Ferumoxytol, …

Quantitative patient‐specific quality assurance prediction using MLC mean leaf gap and PTV volume

Caroline M. Colbert, Eric C. Ford, Minsun Kim

Abstract Rigorous patient‐specific quality assurance (PSQA) is essential to radiation therapy safety. As logfile‐based PSQA gains adoption, quantitative methods to select certain high‐complexity treatment plans for additional measurement‐based PSQA can help to ensure a comprehensive QA program. We propose a simple metric …

Ferumoxytol-enhanced Cardiac MRI for Delineation of Intramyocardial Hemorrhage

Arutyun Pogosyan, Caroline M. Colbert, Mary Keushkerian, Gregory A. Fishbein et autres

Motivation: Intramyocardial hemorrhage (IMH) frequently occurs in acute myocardial infarction (AMI) and is associated with adverse outcomes. While T2* cardiac magnetic resonance (CMR) imaging has emerged as the reference standard for noninvasive IMH detection, it relies on the paramagnetic properties of hemoglobin …

Hitting Moving Targets in Cancer Treatment

Jessica M. Fagerstrom, Victoria Bry, Caroline M. Colbert, Cheyann Windsor

In this article, we will explore the way radiation can be used to treat cancer. Radiation for cancer therapy consists of high-energy particles or light that can damage living cells, including cancer cells. Radiation beams can be generated using a special machine, …

ECG‐free cine MRI with data‐driven clustering of cardiac motion for quantification of ventricular function

Zhengyang Ming, Arutyun Pogosyan, Chang Gao, Caroline M. Colbert et autres

BACKGROUND: Despite the widespread use of cine MRI for evaluation of cardiac function, existing real-time methods do not easily enable quantification of ventricular function. Moreover, segmented cine MRI assumes periodicity of cardiac motion. We aim to develop a self-gated, cine MRI acquisition …

ECG-free 2D cardiac cine MRI with data-driven clustering

Zhengyang Ming, Caroline M. Colbert, Ruan Dan, Holden H. Wu et autres

Conventional 2D cardiac cine imaging relies on ECG-gating whereas self-gated approaches mitigate ECG-dependency by assuming that cardiac motion is periodic with well-defined frequencies. This assumption breaks down when patients have irregular cardiac rhythm. We propose a segmented Cartesian golden step balanced steady-state …

Fractional myocardial blood volume by ferumoxytol‐enhanced MRI : Estimation of ischemic burden

Caroline M. Colbert, John Hollowed, Dylan N. Nguyen, Sandra Duarte‐Vogel et autres

Purpose To investigate model‐fitted fractional myocardial blood volume (fMBV) derived from ferumoxytol‐enhanced MRI as a measure of myocardial tissue hypoperfusion at rest. Methods We artificially induced moderate to severe focal coronary stenosis in the left anterior descending artery of 19 swine by …
