Evaluation of Cerebral Hemorrhage Volume Using Transcranial Color-Coded Duplex Sonography

Abstract

Transcranial color-coded duplex sonography (TCCS) is a useful tool for evaluating cerebral structures. The aim of this study was to examine whether TCCS is useful for evaluation of hematoma volume. Patients with supratentorial intracranial hemorrhage within 24 hours of onset were enrolled. We measured major longitudinal, sagittal in axial plane, and coronal diameter of hematoma on computed tomography (CT) and on TCCS. We estimated hematoma volume using the formula, V = longitudinal × sagittal × coronal/2. The correlation between the hematoma volume on TCCS and CT was studied. Of 48 patients with acute supratentorial cerebral hemorrhage admitted to our hospital, 20 patients with temporal windows (age, 67.5 ± 14.8 years; male, 15) were enrolled. A good correlation was found between TCCS and CT for longitudinal, sagittal, coronal diameter, and hematoma volume (r= .907, P < .0001; r= .811, P < .0001; r= .595, P= .0056; and r= .856, P < .0001). Bland-Altman test showed a good agreement between CT and TCCS, the mean difference between both methods was .31. TCCS appears to be a useful method for evaluating hematoma volume.
