There is a significant difference between calculated dose and measured dose. The use of organ activity estimation based on drawn ROI and the latest version of ICRP 106 dose coefficient should be explored deeper to obtain accurate radiation dose to patients.
A positive attitude is an essential element towards delivering a high-quality patient care for older people. A consequence of aging population in Malaysia is that Medical imaging students are increasingly exposed to older people during their clinical attachments and importantly as a graduated technologist. This study attempted to determine the Medical Imaging students' attitudes towards elderly in Malaysia based on 5 selective characteristics. This study employed a self-administered questionnaire involving 283 students. The finding revealed that well exposed and good result students' have a better attitude towards elderly. This study suggested relevant educational intervention and community engagement program.
Introduction: Proton magnetic resonance spectroscopy (1H-MRS) is an advanced magnetic resonance imaging (MRI) technique that permits the molecular characterization by detecting signals of the water, lipids, and metabolites such as lactate, N-acetyl aspartate (NAA), glutamine, creatinine (Cr), and choline (Cho) in the region of interest. 1H-MRS technique has widely explored the area in the brain, breast, prostate, and optical radiation. However, there are limited literature on MR spectroscopy techniques in musculoskeletal (MSK). The primary purpose of this pilot study is to evaluate lower limb muscles strength pre-and post-resistance straining in lightly active subjects using single-voxel 1H-MRS with different voxel sizes. Methods: The study examined the vastus lateralis muscle of nine male adults 18-26 years of age, body mass index (BMI) = 21.9-38.0 kg/m2. Each subject underwent 1.5 T single voxel, short echo time, point resolved proton MRS at pre- and post- resistance training. Results: The Wilcoxon signed-rank test was performed and was found no significant difference between 20 mm2 and 30mm2 voxel size for NAA, Cr, and Cho for pre- and post-resistance training. Conclusion: The finding of this study shows no improvement of the metabolite’s quantification from two different sizes of a voxel. However, it may be helpful to explore a different aspect of technique in 1H-MRS imaging to investigate the muscle size, volume, and musculoskeletal properties with significant conditions such as musculoskeletal diseases, muscle injuries as well as in sports sciences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
