[Reliability of a simplified method of localization of CT images. Correlation with stereotaxic results in 30 cases]. / Fiabilité d'une méthode simplifiée de transposition des images TDM. Corrélations au repérage stéréotaxique dans 30 cas.

ABSTRACT

A simplified method of localization of cerebral lesions by reference to CT Scan images was compared systematically in 30 cases, with localization obtained under stereotaxic conditions. The comparison was made in reference to the pineal gland and certain ventricular landmarks. The uncertainty of the method in an angular plane is less than or equal to 2,5 degrees; it is less than or equal to 3 mm in a linear plane in more than 90% of the cases.
