Training Deep Learning Based Dynamic MR Image Reconstruction Using Synthetic Fractals

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate whether synthetically generated fractal data can be used to train deep learning (DL) models for dynamic MRI reconstruction, thereby avoiding the privacy, licensing, and availability limitations associated with cardiac MR training datasets.

Comparative Performance Analysis of an Open Source Motion‐Compensated Cardiac Diffusion Sequence Across Different MRI Systems and Gradient Strengths—A Pilot Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To validate the performance of an open‐source cardiac diffusion sequence framework and to investigate hardware‐based performance differences. Methods Three second order motion compensated sequence files were compiled using Pulseq and applied across different MRI systems to image five volunteers.

A Review of the Australian MRI Linac Program: From Pie in the Sky to Research Milestone

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT The Australian Magnetic Resonance Imaging (MRI) Linear Accelerator program (MRI linac) was a major research project that aimed to build and test a unique MRI linac prototype for cancer treatment. It aimed to improve radiotherapy anatomical targeting and explore physiological targeting. The purpose of this report is to summarise the development

Multiresolution comparison of fetal CINE MRI at 0.55 T

ISMRM Annual Meeting
In this study, we demonstrate the feasibility of CINE fetal CMR at 0.55 T at multiple spatial resolutions. First, real-time images are reconstructed for motion-correction and cardiac gating. Fetal cardiac CINEs are then reconstructed using the corrected data. Retrospective CINEs have higher SNR relative to their corresponding real-time reconstructions.

Structured micro‐ultrasonography training improves prostate cancer detection and management decisions

BJU International, EarlyView.
Objective To evaluate whether a structured 2‐day micro‐ultrasonography (microUS) training curriculum improves diagnostic performance and management decisions for clinically significant prostate cancer (csPCa) detection in novice readers. Subjects and Methods A total of 20 participants with limited microUS experience completed the Mannheim Micro ...

Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
