Table 1.
Twenty five fetal MRI cases: gestational age (GA) in weeks, the GA group (Gr), atrial diameter (AD) measured for left lateral ventricles (LLV) and right lateral ventricles (RLV) in millimeters, volumetric measures including intracranial volume (ICV) in milliliters, ventricular volume (VV) in milliliters, and finally the consensus assessment of VM for each case (M for mild VM and S for severe VM). Values highlighted in BOLD indicate VM diagnosis based on those measures. The AD values shown in parentheses could not be measured by ultrasound due to obscured view by the nearfield artifact or difficult positioning, and were measured on fetal MRI by the radiologists (this was part of clinical evaluation).
