Numerical Calculation on Electromagnetic Energy Absorption in Pregnant Woman by RF Coil for MRI System
The numerical calculations including voxel human model with an anatomical structure for electromagnetic field and temperature rise induced by electromagnetic energy absorption have been widely investigated over the past dozen years or so. This paper presents the computational electromagnetic dosimetry inside an anatomically based pregnant woman models exposed to electromagnetic wave during magn...
متن کاملPerioperative radiation exposure in a pregnant woman
The perioperative imaging of a pregnant woman presents a unique challenge to orthopaedics surgeon as concern about the radiation risk to the embryo or fetus. This article highlights effect of radiation exposure on foetus.I would like to discuss about the amount of radiation exposure in a pregnant woman during fluoroscopic guided closed femoral Interlock nailing as radiation has significant...
متن کاملChanges of Cortisol and Glucose Concentrations in Rats Exposed to MR Imaging Field
Background: MR imaging is one of the best diagnostic modalities in medicine. During an MR imaging examination, three types of field are employed to produce images. Various experimental studies have been performed about the effects of each single type of field but only few studies are available on their combination to generate MR imaging. The main objective of this research work is to study the ...
متن کاملGiant Juvenile Fibroadenoma Presenting in a 15-year-old Pregnant Woman: a Case Report
Fibroadenoma is the most common benign mass of breast in females 20-50 years of age. Juvenile fibroadenoma accounts for only 4% of total fibroadenomas. Moreover, the incidence of giant juvenile fibroadenoma is found to be only 0.5% of all fibroadenomas. A 15-year-old woman at the 12th week of gestation was referred to the Shahid Sadoughi Hospital, Yazd, Iran because of a mass in the right breas...
متن کاملNumerical evaluation of SAR within whole-body pregnant woman models in MRI birdcage coil
Introduction To ensure that the RF energy absorbed by human subjects during an MRI procedure does not cause hazardous body temperature increase, regulatory committees have developed limits on local and whole body average SAR[1]. These limits have been proven to be reasonable for adults. However, their applicability for a pregnant woman, fetus or child needs to be further investigated. Some prev...
