DOI: 10.1002/jmri.27921
Abstract: Hepatic iron content (HIC) is an important parameter for the management of iron overload. Non‐invasive HIC assessment is often performed using biopsy‐calibrated two‐dimensional breath‐hold Cartesian gradient echo (2D BH GRE) R2*‐MRI. However, breath‐holding is not… read more here.

DOI: 10.1002/jmri.28325
Abstract: Cardiac MRI is an important imaging tool in congenital cardiac disease, but its use has been limited in the neonatal population as general anesthesia has been needed for breath‐holding. Technological advances in four‐dimensional (4D) flow… read more here.

DOI: 10.1002/jmri.28337
Abstract: MRI acquisition for pediatric pancreatic fat quantification is limited by breath‐holds (BH). Full segmentation (FS) or small region of interest (ROI) analysis methods may not account for pancreatic fat spatial heterogeneity, which may limit accuracy. read more here.

DOI: 10.1002/mrm.26392
Abstract: Conventional fat/water separation techniques require that patients hold breath during abdominal acquisitions, which often fails and limits the achievable spatial resolution and anatomic coverage. This work presents a novel approach for free‐breathing volumetric fat/water separation. read more here.

DOI: 10.1002/mrm.27723
Abstract: For free‐breathing renal perfusion imaging using arterial spin labeling (ASL), retrospective image realignment has been found essential to reduce subtraction artifacts and, independently, background suppression has been demonstrated to reduce physiologic noise. However, negative results… read more here.
