The use of stereotactic volume calculation is highly recommended in planning, follow up, and determination of the outcome in patients participating in radiosurgical treatment and should lead to more uniform reports of the response to treatment.

Object. Volume estimation is one of the most important criteria in the evaluation and follow up of radiosurgical treatments and outcomes; however, several limitations are involved in the calculation estimation of target volumes. Methods. Retrospective and prospective studies were conducted to evaluate the efficacy of a new noninvasive stereotactic method when it is compared with geometric volume calculation of intracranial tumors for planning stereotactic radiosurgery treatment as well as for follow up and outcome evaluation. Two equations were created that permit comparison of the calculated and measured volumes. These equations took linear and quadratic forms, respectively. Volume estimation using the stereotactic approach compared with traditional volume calculation gave more accurate results regardless of the shape and size of the lesion. Conclusions. The use of stereotactic volume calculation is highly recommended in planning, follow up, and determination of the outcome in patients participating in radiosurgical treatment and should lead to more uniform reports of the response to treatment.

La Administración de Bogotá, D.C. se interesa en la determinación de la viabilidad de proyectos urbanos en un ámbito en el que se trata con bienes no mercadeables. La viabilidad de un proyecto urbano se revelará en al menos tres ámbitos: el económico, el social y el financiero. Un proyecto se dirá fuertemente viable si su impacto supone que el beneficio neto de su aplicación es estrictamente positivo dado que es económica, ambiental y financieramente factible; se dirá que el proyecto es débilmente viable, si es viable en al menos una de las tres dimensiones. Una aproximación metodológica que combina microsimulaciones con técnicas de evaluación de tratamientos en la evaluación ex ante de las propuestas de intervención arroja resultados experimentales que sugieren posibles contribuciones de este metodología en la priorización de iniciativas para el desarrollo urbano a la luz de las exigencias normativas de desarrollo territorial.
