Dosis de efectividad de radiación utilizada en estudios de cráneo, cuello, tórax y abdomen con un tomógrafo multicorte de 64 canales en el Hospital José Carrasco Arteaga Cuenca, septiembre del 2014-febrero del 2015

Abstract

Computed tomography allowing TCM has great advances in noninvasive diagnosis of various diseases. At present most of the applied radiation arises from the use of CT, followed by nuclear medicine and fluoroscopy. The aim of our research was to determine the effective dose in studies of skull, neck, thorax and abdomen with a 64-channel Multislice Tomography in Arteaga's José Carrasco Hospital in Cuenca Cato, during the period from September to February 2014 -2015. 3129 cases with a mean age of 48.58 years with the largest age group in patients 16 years and older with 90.3% were studied; the most common female sex was 50.5%. 4 types of tomographic methods were studied, being the most frequent with 68.1% skull and neck less frequent with 1%. The maximum effective dose used was 21,98mSv in the group of 16 years or more and the minimum 0,38mSv in studies of the skull of the same group. The effective dose in all CT without contrast in the group aged 16 and over did not exceed baseline levels. The value of the effective dose in all CT with contrast in the group aged 16 years and over exceeded baseline levels. Because no reference levels effective dose for pediatric groups found, the DLP was studied found higher levels in the first age group. The results obtained in this research will be disseminated in the Journal of the Faculty of Medicine of the University of Cuenca and study serve as a basis for future comparisons.
