Journal ArticleDOI
Radiation dose to newborns in neonatal intensive care units.
TL;DR: DRLs for neonates in the authors' province were slightly higher than values reported by other studies such as European national diagnostic reference levels and the NRPB reference dose, which was related to using a high mAs and a low kVp applied in most departments and also a low focus film distance (FFD).
Journal ArticleDOI

Malakeh Malekzadeh,Shahrokh Abbasi-Rad,Mohamad Shahgholi,Parisa Naghdi,Marzieh Sadat Hoseini,Niloofar Ayoobi Yazdi,Mohammad Bagher Shiran,Hamidreza Saligheh Rad +7 more
TL;DR: This study designed and evaluated the accuracy and precision of a homemade QCT calibration phantom using a whole-body spiral CT scanner and provides practical directions for applying a homemade calibration phantom for bone mineral density quantification in QCT technique.
Journal ArticleDOI
Quantifying cortical bone free water using short echo time (STE-MRI) at 1.5 T.
Shahrokh Abbasi-Rad,Atena Akbari,Malakeh Malekzadeh,Mohamad Shahgholi,Hossein Arabalibeik,Hamidreza Saligheh Rad +5 more
TL;DR: Ste-MR imaging with dual-TR strategy is a clinical solution for quantifying cortical bone ρfree and T1free and age is validated by comparing the obtained results (MR-derived results) with dehydration results.
Journal ArticleDOI
Cortical Bone Mechanical Assessment via Free Water Relaxometry at 3 T.

TL;DR: In this article, the effect of noise on T1 quantification was evaluated by measuring the signal-to-noise ratio by dividing the signal of each segmented sample to background noise, and then the samples were subjected to mechanical compression test to measure the toughness, yield stress, ultimate stress, and Young modulus.
Journal ArticleDOI
Local Diagnostic Reference Levels for Common Pediatric X-Ray Examinations in Khorasan Razavi Province, Iran
TL;DR: The findings revealed that local DRLs in this study are higher than the corresponding values, recommended by the Commission of European Communities (CEC) and National Radiological Protection Board (NRBP), which were related to the use of low kVp, relatively high mAs in all centers, and use of grid for most of the patients.
