To explore the growth trend of fetal lateral ventricular volume, for understanding the relationship between atrial diameter (AD) and volume in normal fetus and fetus with ventriculomegaly. Overall, 97 sequential fetal head magnetic resonance imaging scans were performed; these pertained to 50 fetuses with normal lateral ventricles [normal group; gestational age (GA): 24–38 weeks] and 47 fetuses with ventriculomegaly (VM) (VM group; GA: 24–37 weeks). The left, right, and total lateral ventricular volume were measured using 3-dimensional magnetic resonance hydrography (MRH). Correlation coefficient (r) was calculated to assess the relationships of measurements. Lineal regression analysis was used to assess correlation of AD and GA with volume. Between-group differences in terms of AD and volume were assessed using t test. Significant linear growth was observed in the total lateral ventricular volume compared with GA in the normal group with a relative growth rate of 2.87% per week ( P <.001). Significant linear relationship between AD and volume was observed, and a significant equation was acquired in the normal group and VM groups, respectively, using the simple linear regression model: left volume = 0.438 ∗ normal left diameter (NLD) + 1.359; right volume = 0.493 ∗ normal right diameter (NRD) + 1.012; left volume = 0.959 ∗ left diameter in VM (VLD) − 2.074; right volume = 0.799 ∗ right diameter in VM (VRD) − 0.443. A significant equation was obtained in the normal group and the VM group, using the multiple linear regression model: Total volume (mL) = 0.396 ∗ NLD + 0.410 ∗ NRD + 3.101; and total volume = 0.989 ∗ VLD + 0.834 ∗ VRD − 3.141, respectively. In terms of AD and volume, the left lateral ventricle was significantly larger than the right side in both groups. The volume of lateral ventricle in AD ≥10 mm group was larger than that in the AD <10 mm group. The total volume in the VM group was significantly larger than that in the normal group. The total lateral ventricular volume increased with GA. AD can be used to evaluate the fetal ventricular volume.

“…Based on the pixel and spacing information, volume models enable the observation of structures in a body not only on classical horizontal, coronal, and sagittal planes for the diagnosis of common diseases,1 but also on various oblique planes for specific clinical fields, such as a probe's eye and trajectory view on the magnetic resonance images (MRIs) in deep brain stimulation surgery,23 neuro-ocular plane on computed tomographs (CTs) of ophthalmology,45 and ultrasonographic view for heart and liver diagnoses 67. Furthermore, volume models of MRIs can be used for volumetric analysis of a structure for the diagnosis of various diseases89 and for human simulation purposes, such as phantoms for electromagnetic dosimetry 1011…”

“…Nevertheless, real-color volume models from real-color sectioned images (> 24 bits color) are naturally superior to grayscale volume models (< 16 bits gray),1213 since the sectioned images are superior to MRIs 141516. One reason why only gray color volume models can be produced is because the software can read only digital imaging and communications in medicine (DICOM) format, which includes information of a patient, scanning methods, etc 8917…”

BackgroundVolume models made from magnetic resonance images on computed tomographs can produce horizontal, coronal, sagittal, and oblique planes that are used widely in clinics, although detailed structures cannot be identified. Existing real color volume models are mostly commercial and their production methods have not been released. The aim of this study was to distribute free of charge, real-color volume models produced from sectioned images with the production method.MethodsThe original voxel size of sectioned images was increased appropriately so that the volume model could be handled by typical personal computers. By using Dicom Browser and MRIcroGL, the sectioned images were processed to become the volume models.ResultsOn the MRIcroGL, the resultant volume model with the voxel size of 0.5 × 0.5 × 0.5 mm3 could be displayed and freely rotated. By adjusting variables of the software, desired oblique planes could be produced instantly. With overlay function, a model of segmented structure can be overlapped to the entire volume models. The sectioned images with high quality and the segmentation data of Visible Korean enabled the identification of detailed anatomical structures on the planes.ConclusionThe volume models can be used by medical students and doctors for learning sectional anatomy. Other researchers can utilize the method of this study to produce volume models from their own sectioned images.
