Achieving sufficient spatial and temporal resolution for dynamic applications in cardiovascular magnetic resonance (CMR) imaging is a challenging task due to the inherently slow nature of CMR. In order to accelerate scans and allow improved resolution, much research over the past three decades has been aimed at developing innovative reconstruction methods that can yield high-quality images from reduced amounts of k-space data. In this review, we describe the evolution of these reconstruction techniques, with a particular focus on those advances that have shifted the dynamic reconstruction paradigm as it relates to CMR. This review discusses and explains the fundamental ideas behind the success of modern reconstruction algorithms, including parallel imaging, spatio-temporal redundancies, compressed sensing, low-rank methods and machine learning.

Background: Fetal MRI is increasingly used to investigate fetal lung pathologies, and super-resolution (SR) algorithms could be a powerful clinical tool for this assessment. Our goal was to investigate whether SR reconstructions result in an improved agreement in lung volume measurements determined by different raters, also known as inter-rater reliability.
Materials And Methods: In this single-center retrospective study, fetal lung volumes calculated from both SR reconstructions and the original images were analyzed.

Nasal alar reconstruction is complex due to the region's anatomy and aesthetic importance. This report describes repairing a small, full-thickness alar rim defect in a 36-year-old man using a rotational columellar skin flap with septal cartilage grafting. This single-stage technique achieved good color match, symmetry, and minimal donor-site morbidity.

Minimally invasive pancreaticoduodenectomy is gaining success among surgeons also for the increasing use of robotic approach. Ideal candidates are patients with small, confined tumor and dilatated Wirsung duct which is a quite rare clinical conditions: in fact, most of minimally invasive pancreaticoduodenectomies are performed for periampullary cancer, easy to remove but with soft pancreatic remnant and tiny Wirsung duct. The result is the technical challenge of the pancreatico-enteric reconstructions.
