Abstract

Objectives: To determine the normal range of third ventricle demensions in Vietnamese people by using Magnetic resonance imaging (MRI) and examine the relation between those parameters with age and gender. Materials and Methods: A cross-sectional study was conducted on 120 healthy individuals by using magnetic resonance imaging at Department of Imaging Diagnosis,. Ninh Thuan province’s hospital. Using 3D Axial T1W sequence for third ventricle measurement.  and age by computing the Pearson correlation coeficient at a significance level of 0.05. Results: The average age of the study sample is 42.62 ± 10.63. Length, width of the third ventricle in males were generally larger than in females (length in male: 25.81 ± 2.51mm, length in female: 23.43 ± 1.32mm; width in male: 5.41 ± 1.66mm, width in female: 4.35 ± 1.24mm), excluding third ventricle height was larger in female than in male (Height in male: 17.05 ± 1.39mm, height in female: 17.34 ± 1.43mm).  Furthermore, the difference in anatomical parameters of the third ventricle between genders were statistically significant, except the third ventricle height. The third ventricle width (TVW) and third ventricular ratio (TVR) both showed a positive significant moderate correlation with age (TVW: r = 0.315, p < 0.05; TVR: r = 0.331, p<0.05). Conclusions: Magnetic resonance imaging is a non-invasive and reliable method that can provide accurate measurement regarding the structure and anatomical morphology of the third ventricle, as well as the relation of its parameters with anthropometric indices, offering initial guidance for clinicians in post-treatment monitoring.
