The article "Assessment of superior mesenteric vascular flow quantitation in children using four-dimensional flow magnetic resonance imaging" suggests to use of four-dimensional (4D) flow magnetic resonance imaging (MRI) which is also to measure the blood flow in the superior mesenteric vein (SMV) in pediatric patients over the traditional method. The study focuses on assessing the potential of SMV and superior mesenteric artery (SMA) flow quantification in children utilizing 4D flow MRI. It included 9 pediatric patients aged 18 years and below where 5 were male and 4 were female patients, on whom magnetic resonance enterorrhaphy (MRE) with 4D flow MRI protocol was used. Statistical analysis was performed using MedCalc. Measurements of SMV and SMA between two readers were calculated using Bland-Altman analysis. The results stated that six patients showed no MRE evidence of active inflammatory bowel disease, two patients showed unmarkable bowel appearance on MRI and one patient showed normal MRE without endoscopy performed at the same timeframe. The study utilized available 4D flow MRI sequences in this study aiming to show the feasibility of 4D flow quantitation of SMA and SMV flow in pediatric patients. The study also discovered good agreement for both peak velocity and peak speed measurements of SMA and SMV.
