DOI: 10.1002/acm2.13650
Abstract: Abstract Purpose Since 4D‐MRI is inadequate to capture dynamic respiratory variations, real‐time cinematographic (cine) MRI is actively used in MR‐guided radiotherapy (MRgRT) for tumor motion evaluation, delineation, and tracking. However, most radiotherapy imaging platforms do… read more here.

DOI: 10.1002/mrm.26923
Abstract: Segmentation of cardiac cine MRI data is routinely used for the volumetric analysis of cardiac function. Conventionally, 2D contours are drawn on short‐axis (SAX) image stacks with relatively thick slices (typically 8 mm). Here, an acquisition/reconstruction… read more here.

DOI: 10.1016/j.sleep.2017.10.006
Abstract: OBJECTIVES/BACKGROUND Tonsillectomy and adenoidectomy (T&A) lead to resolution of obstructive sleep apnea (OSA) in most children. However, OSA persists in about 25-40% of children. Cinematic magnetic resonance imaging (cine MRI) can aid the management of… read more here.

DOI: 10.1186/s41747-021-00205-5
Abstract: Background Colonic manometry is the current reference standard for assessing colonic neuromuscular function in children with intractable functional constipation (FC). Recently, cine magnetic resonance imaging (cine-MRI) has been proposed as a non-invasive alternative. We compared… read more here.

DOI: 10.3390/diagnostics10040241
Abstract: We propose fast phase-contrast cine magnetic resonance imaging (PC-cine MRI) to allow breath-hold acquisition, and we compared intracranial hemo- and hydrodynamic parameters obtained during breath holding between full inspiration and end expiration. On a 3.0… read more here.
