Hounsfield units mensuration is used to assess the tissue attenuation, which is a feature in each one of them, offering a measure of distinction between gray and white matter, showing that the level of basal ganglia seems to be the most sensitive location for CT to study this difference, since they have higher metabolic demand, will be the first structures showing perfusion abnormalities. Between October and December 2008 Hounsfield values were obtained from the basal ganglia of 150 patients. Classified by radiological diagnosis in normal and pathological, using T-student with a T standart value of 1.96; a cut-point of 0.692 was found corresponding to the average between the basal ganglia values from the right and left hemispheres. For equality of means between normal and pathological status; cut of points -1.620 in the right hemisphere and -0.129 in the left hemisphere were obtained. We conclude that there is no statistically significant difference between the basal ganglia of the right and left hemispheres, nor between normal and pathological states in both hemispheres.
