A total of 226 volunteers i.e. 128 male and 98 female were screened at Radiology Department King Abdul-Aziz University Hospital. They were categorized as smokers and non- smokers;the number of smokers was 99 cases i.e. 48 Cigarette smokers and 51 Shisha smokers, and the non-smokers were 127 cases. The information was gathered via a questionnaire distributed at the radiology department. Ultrasonography of thyroid and thyroid function test were performed for 166 participants;and data were analyzed Using SPSS version 22 and Microsoft excel. The study was carried out based on random selection and findings revealed that most of the cases were in the age group between 20 to 30 years old, high body mass index (BMI) was 33.1 kg/m2 in persons above 60 years old and the highest percentage smokers in the age group from 20 to 30 years (40.02%). Ultrasonography of thyroid showed 96 (58%) normal cases, 46 (28%) abnormal “solid” cases and 24 (14%) abnormal “cyst” cases. A lower proportion of cigarette and shisha smokers (15.4% and 5.6% respectively) had an enlarged thyroid gland compared to no cigarettes or shisha smokers (47.9% and 47.3% respectively). The difference between these frequencies was statistically significant (Chi-square = 9.446 and 11.424, p = 0.002 and p = 0.001 for cigarette and shisha smoking respectively). Consequently, it can be concluded from this research that there are no direct significant values correlating smoking habit to thyroid volume or function. However, it is always recommended not smoke due to other well-known threats.展开更多

We investigated an economic imaging composition that characterizes bone density in imaging for quality assurance and educational purposes. Four different compositions were tested to reveal the best composition in simulating bone density in X-ray imaging. Hydrated lime was discovered to be the most suitable because it is durable (stiff and does not crumble), easy to source and process, and attenuates imaging X-rays enough to resemble real bone. Hydrated lime provides a significantly better phantom than the other combinations used.展开更多
