Images obtained with the radial VIBE sequence were reported to have less motion artifacts [MB1] than Cartesian sampled 3D VIBE T1W images in various pediatric regions. In this study, all cases with GI anomalies were diagnosed with acceptable image quality, including dilatation, narrowing, and herniation of the intestine. All parts of the colon were visualized and measurable after 24 weeks’ gestation. The results also indicate that an increasing trend of colon calibers with advancing gestational age, and a GA-specific caliber pattern that may improve the diagnosis of GI tract abnormalities. [MB1]There is no quantification & no image comparison proving this,
