Morphometric evaluation of neuroimaging as a prognostic factor of survival in patients with cerebral hemorrhage

The data constitute a hierarchically ordered system, where computed tomography (CT) images are nested within individuals: the units of study in level-1 are the images and units of study in level-2 are of individuals. There are 39 patients (13 women and 26 men) with a diagnosis of spontaneous intracerebral hemorrhage (ICH) and who were carried out a CT scan within the first 6 hours of initiating symptoms. Ages were in an interval between 48 and 87 years. Of the total patients, 11 died after the hemorrhage. The morphometrical measurements of each of the hemorrhage images obtained by CT are: area, perimeter, elliptical shape factor, maximum diameter and minimum diameter. The morphometrical variables were measured using the MADIP system (Rodríguez et al. 2001) and a transformation was applied to avoid the undue importance of disproportionate ranges caused by the different units of measure of some variables.
