Propuesta metodológica para el uso del programa PCXMC 2.0 en modalidad rotacional

RESUMEN Durante los procedimientos intervencionistas que utilizan fluoroscopia, se entrega a los pacientes diferentes niveles de dosis de radiación, que pueden tener un impacto a corto, mediano o largo plazo, así como en su severidad. Esto en función del tipo de radiación utilizada y de la sensibilid...

Lesiones oculares y radiación ionizante

Rev. colomb. cardiol; 27 (S1), 2020
El número y la complejidad de los procedimientos de diagnóstico e intervencionismo cardiovascular han incrementado de manera significativa, hecho que genera mayor exposición a dosis bajas de radiación ionizante debido a la radiación dispersa por el paciente. El cristalino es una de las estructuras m...

Intensity modulated radiotherapy (IMRT) or conformational radiotherapy (3D-CRT) with conventional fractionation for prostate cancer: Is there any clinical difference?

Int. braz. j. urol; 45 (6), 2019
ABSTRACT Purpose: To compare the treatment outcomes of a cohort of prostate cancer patients treated with conventional schedule using IMRT or 3DRT technique. Materials and Methods: Between 2010-2017, 485 men with localized prostate cancer were treated with conventional radiotherapy schedule with a total...

Gamma knife radiosurgery for trigeminal neuralgia: first case series from Latin America

Arq. neuropsiquiatr; 77 (4), 2019
ABSTRACT Gamma Knife® radiosurgery (GKRS) for trigeminal neuralgia is an effective treatment with at least a 50% reduction of pain in 75-95% of patients. Objective: To present the first series of patients treated for trigeminal neuralgia using GKRS in Latin America. Methods: Retrospective analysis. An...

Radiotherapy and immune response: the systemic effects of a local treatment

Clinics; 73 (supl.1), 2018
Technological developments have allowed improvements in radiotherapy delivery, with higher precision and better sparing of normal tissue. For many years, it has been well known that ionizing radiation has not only local action but also systemic effects by triggering many molecular signaling pathways. The...
