Abstract
Hemorrhage volume, level of consciousness and ventricular extension and expansion of the hematoma are prognostic factors for clinical outcome of intracerebral hemorrhage (ICH). Volumetric measurement of ICH has an important clinical and prognostic meaning. The aim of this study was to compare the methods which are being used to measure ICH volume: the ABC/2 method and semiautomated method with computer volumetric program. Our study represents a retrospective analisys of 54 patients (61.11% male and 38.89% female patients with mean age 67.20±10.30 years) who underwent computed tomography (CT) scan of endocranium. Volumetric measurements were performed by ABC/2 method and computer semiautomated method with volumetric program on Аdvantage Windows 3D Workstation 4.1. Mean value and standard deviation obtained by ABC/2 method were 41.98±35.47, while mean value and standard deviation obtained by computer semiautomated method with volumetric program were 52.12±45.61. There is a statistically significant difference between the values obtained by these two methods (p=0.03). The absolute difference was 10.14 cm. The values acquired by computer method were by 19.46% higher than those acquired by formula. There is a statstically strong positive correlation between these two methods (r=0.852, p<0.05). Both methods are very useful in determining ICH volume. Our results show that values obtained by computer semiauthomatic method were by 19.46% higher than those obtained by the elliptic equation. Elliptic equation-ABC/2 method is better for measuring regular ICH shapes and fast orientation, while semiautomated computer method is more accurate and more selective.

Highlights
Intracerebral hemorrhage (ICH) is an urgent neurolocigal and neurosurgical condition with potentially high mortality
In patients with ICH caused by the arterial hypertension and trauma, computed tomography (CT) angiography was normal, without the signs of intracranial aneurysms or arteriovenous malformations
In the study by Maeda et al [8], the values determined by ABC/2 method in relation to the planimetric method were by 14.9% lower (2.24 cm3), while Wang et al showed in their study [9] that values obtained by ABC/2 method significantly exceed the values obtained by computer analysis, which can pose a problem in clinical decision making, mortality forecasting and functional results
Summary
Intracerebral hemorrhage (ICH) is an urgent neurolocigal and neurosurgical condition with potentially high mortality. The most common causes of ICH are hypertension, arteriovenous malformation, head trauma, tumors and aneurysms [1]. The initial volume of the hematoma correlates with clinical outcome and is used as a 34 guide for acute treatment and prognosis [2]. Thirty-day mortality is 44%, with half of the deaths occuring in the acute phase, especially during the first 48 hours [3]. There is no proven effective treatment as well as the ability to promptly determine the prognosis of the patient. The volume of hemorrhage, level of consciousness and existence of intraventricular expansion represent the prognostic factors for clinical outcome of ICH [4]. Volumetric measurement of ICH has great clinical and prognostic significance [5]
