Resumen

DEL VALLE, RAMIRO et al. MEDICIÓN VOLUMÉTRICA ESTEREOTÁXICA NO INVASIVA VS VOLUMETRÍA GEOMÉTRICA PARA LA INDICACIÓN Y EVALUACIÓN DE LOS TRATAMIENTOS CON RADIOCIRUGÍA. Arch. Neurocien. (Mex., D.F.) [online]. 2004, vol.9, n.1, pp.14-17. ISSN 0187-4705.

Although radiosurgical volume estimation is one of the most important criteria in the evaluation and follow up of radiosurgical treatments and outcomes, several limitations are involved in the calculation or volume estimation. Material and methods: a retrospective and prospective study was conducted in order to evaluate the efficacy of a new non-invasive stereotactic method when it is compared with geometric volume estimation of tumoral intracranial lesions, for planning stereotactic radiosurgery treatments as well as for follow up and outcome estimation. Results: two equations were found when two methods were compared: one lineal and one quadratic. Volume estimation using stereotactic approximation was more adequate to predict tumoral volume as compared with traditional volumetric estimation, and it is not dependent on shape and size of the lesion. Conclusion: use of stereotactic volume estimation is very recommended in the planning follow up and outcome of patients participating in radiosurgical treatments.
