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

Intra-fractional motion errors were quantified for 29 patients who underwent lung Stereotactic Ablative Radiotherapy (SABR) treatment at the cancer centre of QE Hospital. One hundred thirty post-Cone Beam Computed Tomography (CBCT) scans were collected to calculate these errors. In terms of the adequacy of a PTV margin, the intra-fractional motion errors that were calculated are combined with other geometric errors which were taken from historical audit studies. Then, the combined outcome was compared with the common PTV margin that is delineated by most United Kingdom (UK) oncology centres. The findings of this study showed that the systematic component of intra-fractional motion error is equal to 0.08, 0.08 and 0.08 cm in right/left, superior/anterior and anterior/posterior directions, respectively, While the random component of this error is equal to 0.11, 0.13 and 0.14 cm. In addition to that, a PTV margin of 0.5 cm is the appropriate margin for QE Hospital’s patients and this volume is compatible with the common PTV margin that is delineated by the most UK oncology centres. This work concluded that A PTV margin of 0.5 cm is the suitable volume for lung SABR patients at QE Hospital.展开更多

Material and methods: the Descriptive quantitative cross-sectional study conducted in the ultrasound department at Alshaekh Mohammed Ali Fadol hospital in Omdurman locality. The study included 400 healthy Sudanese pregnant women whom in the 1st (late), 2nd and 3rd trimesters (i.e., after 10 weeks gestational age) of different parity and ages (15 years old and above);they have regular menstrual cycle and well certain of their last menstrual period and calculated date of delivery. Ultrasonographic measurement of Full Foot Length1 (FFL1), Foot Full Length2 (FFL2), and Foot Full Width (FFW) of all pregnant women were done. Sonographically we measured fetal foot from 14 to 40 weeks of gestation. Results: the study revealed that the mean FFL1 was 58.7 ± 12.9 mm. The minimum measurement was 18.8 mm, and the maximum was 89.1 mm, while the mean value of FFL2 was 53.4 ± 11.4 mm, with minimum value 17.5 mm and maximum 81.7 mm, and the mean FFW was 23.7 ± 5.1 mm, with minimum value 7.0 mm and maximum 38.0 mm. Conclusion: a strongly significant relationships were observed between (FFL1, FFL2, FFW) and gestational age (p = 0.00). However there is no significant difference between the FFL1, FFL2, and correlations with sex of embryo, residence, occupation, parity, maternal height, socioeconomic status, bleeding during this pregnancy, chronic illness, and caesarian section, moreover there are significant correlations between the FFL1, FFL2 and the (maternal age, maternal weight, and body mass index), but in the measurement of the fetal FFW there were no significant correlations with (sex of embryo, maternal age, body mass index, residence, occupation, parity, socioeconomic status, bleeding during this pregnancy, chronic illness, and caesarian section). Also there are significant correlations between the FFW and the maternal weight and height.展开更多

Thyroid scan was done in 70 students prospectively with no indicative of thyroid disease (age of 19 - 23 yrs). Thyroid scan for students who participated the study took place in the department of Faculty of Applied Medical Sciences, King Abdulaziz University by using an IU 22 Philips ultrasound machine with a 5 - 12 MHz linear transducer. Among the total number of the subjects, 26% was found with abnormal ultrasound findings, 17% of them with cystic nodule, while solid and mixed nodule represented 4% for each. The high rate of abnormal findings of thyroid gland in the study suggested that screening using ultrasound scan was useful in detecting early thyroid disorders.展开更多
