Temperature Changes in the Brain of Patients Undergoing MRI Examination

Abstract

Magnetic Resonance Imaging scanners have become important tools in modern day health care. During the imaging process, total radiofrequency power is transferred from the RF coil to the brain tissues resulting in increase in temperature in the subject being imaged. Currently, reliable and validated means to predict RF heating are not unavailable.This research was conducted to determine temperature changes in the human brain during MRI examination.This study was carried out at two MRI Units in Ghana. One hundred and twenty-six patients were investigated. Data collected include pre- and post-scan tympanic temperatures and specific absorption rates values. The average pre- and post-scan tympanic temperatures measured for Centre A were 36.5
