Transforming pediatric imaging: The role of four-dimensional flow magnetic resonance imaging in quantifying mesenteric blood flow

Figure 1 Representative four-dimensional flow magnetic resonance imaging showing abdominal vasculature including the hepatic artery, portal vein, superior mesenteric artery, and inferior vena cava. Velocity-encoded streamlines are color-coded from 0 cm/second to 100 cm/second. This visualization exemplifies how four-dimensional flow magnetic resonance imaging can dynamically map blood flow direction and velocity in real time, aiding in the evaluation of pediatric gastrointestinal disorders. MRI: Magnetic resonance imaging; IVC: Inferior vena cava; SMV: Superior mesenteric vein; 4D: Four-dimensional.
