Cardiovascular Magnetic Resonance (CMR) native T1 and T2 mapping serve as robust, contrast-agent-free diagnostic tools, but hardware- software-specific sources of variability limit the generalizability data across CMR platforms, consequently limiting interpretability patient-specific parametric data. Z-scores are used to describe relationship observed values mean results obtained in a sufficiently large normal sample. They have been successfully severity quantifiable abnormalities medicine,...
Access to MRI in low- and middle-income countries (LMICs) remains among the poorest world. The lack of skilled personnel exacerbates access gaps, reinforcing long-standing health disparities. Scan With Me (SWiM) program aims sustainably create a network highly technologists LMICs who will facilitate transfer knowledge skills their peers contribute implementation valuable imaging protocols for effective clinical research use.
Cardiovascular magnetic resonance (CMR) cine imaging is still limited by long acquisition times. This study evaluated the clinical utility of an accelerated two-dimensional (2D) sequence with deep learning reconstruction (Sonic DL) to decrease time without compromising quantitative volumetry or image quality.
Cardiac magnetic resonance is the gold standard for evaluating left-ventricular ejection fraction (LVEF). Standard protocols, however, can be inefficient, facing challenges due to significant operator and patient involvement. Although free-running framework (FRF) addresses these challenges, potential of extensive data it collects remains underutilized. Therefore, we propose leverage large amount collected by incorporating interbin cardiac motion compensation into FRF (FRF-MC) improve both...
Robotic hands able to conduct precision in-hand manipulation have become imperative for modern robotic systems. Compliant finger joints provide compliant grasping but the post-grasp orientation of an object varies. Under-actuated, that are capable and reorienting objects one step closer human-like end-effectors. This paper presents a hand prototype with two under-actuated fingers embedded tactile feedback fuzzy system obtain stable grasp, integrated gripper. One fully actuated thumb 3...
Tissue engineering utilizes an interdisciplinary approach to generate constructs for the treatment and repair of diseased organs. Generation small vessels as vascular grafts or envisioned central vessel vascularized is still a challenge. Here, decellularization porcine by non-detergent based protocol was developed investigated. Perfusion-decellularization with sodium hydroxide solution resulted in removal cellular material throughout whole length while preserving structural mechanical...
Motivation: There is a wide discrepancy in MRI accessibility globally, which has created an insurmountable challenge to fulfill the diagnostic healthcare needs of low- and middle- income countries. Goal(s): To train radiographers who can their peers growing network. Approach: The RAD-AID Teach-Try-Use approach was used within 6 weeks deploy basic advanced cardiac (CMR) knowledge, followed by expert image acquisition demonstrations, use cases simulate, analyze optimize scanner-specific...
Quantitative imaging biomarkers such as T1 are promising for assessing focal and diffuse myocardial pathologies across different sites scanners. However, the lack of reliable mapping methods scanner platforms reduces patient access to robust quantitative imaging. CMR Multitasking has shown promise non-ECG free-breathing in heart, primarily at 3T. This work is an initial feasibility study implementing on GE 1.5T MR Radial trajectories, self-gating/training data, framework together provided...
Motivation: CMR Multitasking has shown promise for non-ECG and free-breathing myocardial T1/T2 mapping in the heart, primarily on a single vendor 3T, but 2D T1-T2 not yet been different vendors (e.g., GE) field strengths 1.5T). Goal(s): To extend to 1.5T 3.0T GE MR systems. Approach: We implemented sequence systems evaluated its performance healthy volunteers patients at two sites. Results: generated T1 T2 maps with image quality comparable reference measurements. Impact: provides an...
Cardiac magnetic resonance imaging is often limited by long scan times and the need for multiple breath holds. A Free-Running sequence may overcome this limitation providing 3-D cine data in a free-breathing non-ECG-triggered acquisition of 7 minutes. The clinical applicability method was tested cohort 9 patients with varying pathologies. Myocardial blood-pool volumes ejection fractions were compared between standard 2-D protocols 5-D Free-Running-LIBRE. Free-Running-LIBRE successfully...
