Frequency of cavum veli interpositi in non-psychotic population: a magnetic resonance imaging study.

Abstract

This prospective MRI investigation was performed to determine the incidences of the cavum veli interpositi (CVI) in 505 (242 Male, 263 Female) non-psychotic persons. The mean age of the population was 39,179 +/- 0,904 (40,461 +/- 1,395 Male, 38 +/- 1,166 Female). There was no significant difference between the means of age in male and female groups (t-test, DF=479, p>0,05). The incidences of the CVI were 5.77%, 1.89%, 5.66%, 8.24%, 5%, 4.55%, 7.94%, 3.03% for age group of 0-9, 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79 respectively. There was no significant difference between the incidences of the CVI in age-groups (chi(2)=3.804, DF=7, p>0.05). The incidences of the CVI were 5.54%, 6.61%, 4.56% for whole, male, and female populations respectively. There was no significant difference between the incidences of the CVI in both sexes (chi(2)=1.01, DF=1, p>0.05).
