Abstract

LOPEZ DIAZ, Adlín et al. Combined parameters estimation for Descripción: http://img/revistas/nuc/n61/e01046117.jpgdosimetry treatment planning in Hyperthyroidism using 2D and 3D. Nucleus [online]. 2017, n.61, pp.16-20. ISSN 0864-084X.

Optimization and verification of Specific Patient Treatment Planning with unsealed Descripción: http://img/revistas/nuc/n61/e01036117.jpgsources in hyperthyroidism diseases is a desirable goal from medical and radiation protection viewpoints. In order to verify the estimation of patient’s specific treatment dose and his/her related parameters, a combination of 3 different  apparatus or pieces of equipment used in nuclear medicine were studied - the Iodine Probe, a Philips Forte Camera with pin-hole collimators and a Mediso Nucline with HEGP for planar and SPECT techniques- by using the typical neck phantom and Descripción: http://img/revistas/nuc/n61/e01046117.jpgsources simulating diagnosis and treatment procedure. The linear behavior on diagnostic and therapeutic activity range was verified, showing a linear correlation fitting factor Descripción: http://img/revistas/nuc/n61/e02046117.jpg> 0,99. The differences between thyroid uptake determinations in all equipment were less than 6 % for therapeutic activities and less than 1,1 % in the diagnostic range. The combined protocol to calculate all the necessary parameters for the patient treatment dose planning using 2D or 3D approach was established and verified, avoiding wasting time with gamma cameras and with only one administration of Descripción: http://img/revistas/nuc/n61/e01046117.jpg
