Free-running 5D MRI framework for Pediatric Patients The study was performed in 18 pediatric cardiac patients (8.0 ± 5.6 years, range less than 1–16 years) at the Children’s Hospital of Philadelphia (Philadelphia, Pennsylvania, USA) on a whole-body 1.5T clinical MR scanner (MAGNETOM...
Conclusions Myocardial strain by FT-CMR may effectively detect early myocardial impairment with MINOCA, especially in patients with normal routine MRI.Peer Review reports Background Approximately 1–14% of patients suspected of acute coronary syndrome (ACS) do not show significant coronary artery obstruct...

The reasons for exclusion included contraindications to MRI (n = 58), previous AV access surgery (n = 41), and frailty (n = 32) (Supplementary Table S1). Of the 49 participants who underwent the first CMR scan, 7 had no AVF surgery, and 2 withdrew consent, declining the...
Key questions remain: What are normal hs-cTn levels in truly cardio-healthy subjects screened by CMR? What is the impact on hs-cTn URLs of adopting higher eGFR values (90 mL/min/1.73 m2) as opposed to 60 mL/min/1.73 m2 to screen out subclinical renal disease?
In particular, magnetic resonance imaging (MRI), otherwise known as CMR (cardiovascular magnetic resonance), has become a key image modality in clinical practice due to its unique capabilities for non-invasive imaging of the cardiac chambers and great vessels [4]. A wide range of CMR sequences...
16此外,MRI已被用作肺动脉瓣再干预(PVR)的早期指征。17,18 TOF管理中的这些历史变化可能会影响肺动脉瓣膜再干预的指征;修理决定是选择VS修复还是TAP修复的参数在很大程度上仍有待确定,因此这些患者未来PV干预的预测因素也有待确定。扩大...

Cardiac magnetic resonance imaging (CMRI) is a promising tool for evaluating the structure, function, and myocardial contents of the left ventricle. With T1 mapping, CMRI could measure the extracellular volume (ECV) of the myocardium, which is an indicator of diffuse myocardial fibrosis. Diffuse ...
The Dice coefficient is routinely used to quantify the overlap between manual segmented ground truth and automated segmentation in MRI37,38,39. Results Effect of grid size and Fourier terms We first demonstrate the effects of different N values and b-spline grid size on the Fetal ultrasound ...
