Total intra-cranial volume (TIV) of the Igbo population of Nigeria was carried out using stereology technique. A total of 329 adult subjects of Igbo ethnic group with no cranial and brain abnormalities aged between 18 and 87 years were enlisted into the study (males: 193 and females: 136). They were scanned with a helical dual detector (GE Hi-Speed NX/i Series 8.1). Images were obtained with a slice thickness of 3 mm from the base of the skull to the vertex. Employing the Cavalieri’s sections method with point counting, a grid with a separation distance of 2.4cm was superimposed on the sampled image sections to calculate the TIV of each subject. The mean TIV of males and females were 1298.44 ± 90.67 cm3 and 1186.73 ± 79.05 cm3<8sup> respectively. A comparison of the mean TIV from our study and other studies in other populations showed mild to moderate variation in values which probably due to differences geographical location and race. There was significant difference (p< 0.05) in the value of TIV in the Igbo population when compared with some other populations such as Turkey using the same methodology. Total intra-cranial volume estimate can be applied in forensic investigations to differentiate various ethnic nationalities, in addition to clinical assessment in quantitative imaging to assess disease progression.
