Abstract:
Transcranial duplex color‐flow sonography provides visualization
of intracranial structures, and measures angle‐corrected blood flow velocity in the basal cerebral artenes of adults. In 44 patients
with central nervous system disease, the oblique diameters of the third and the middle part of the lateral ventricle were measured
by transcranial duplex color‐flow sonography using a system with a 2.5‐MHz transducer, and compared to computed
tomography measurements. The correlation coefficients for the third and lateral ventncle measurements were r = 0.83
(p 〈 0.0001, N = 38) and 0.73 (p 〈 0.0001, N = 78), respectively.
A second investigation was performed by transcranial duplex to evaluate intraobserver and mterobserver reproducibility.
The correlation coefficient representing interobserver reproducibility in 27 patients was r = 0.87 (p 〈 0.0001, N = 47) for the
lateral ventricle and r = 0.9 (p 〈 0.0001, N = 49) for the third
ventricle. The intraobserver reproducibility correlation coefficient was r = 0.93 (p 〈 0.0001, N = 22) for the lateral ventricle in
12 patients. In 49 healthy volunteers the oblique diameters of the lateral and third ventricles were age dependent measuring
16.7 ± 2.3 mm and 4.8 ± 1.9 mm, respectively, in those younger than 59 years, compared to 19.0 ± 2.9 mm and
7.6 ± 2.1 mm in those 60 years or older. Therefore, transcranial duplex color‐flow sonography measures noninvasively the third
and the lateral ventncle in adults.
