This was a deceptive cross sectional study aimed to differentiate between benign and malignant tumor using ultrasonography, done in Khartoum area hospital during the period from January 2022 to January 2023. 200 patients with thyroid nodules (20%) 40 males and 160 (80%) females. The study found that most patients had well define margin nodules were 145 (73%) and ill define margin nodules were 54 (27%), most patients had taller-than-wider capsule were 192 (96%) and wider-than-taller capsule were 8(4%), most patients had internal vascularity were 150 (75%) and peripheral were 50 (25%), most patients had No calcification170 (85%) and had calcification 30(15%), most patients had hyper echogenicity were 156 (78%), hypo echogenicity were 30(15%) and iso echogenicity were 14 (7%), most patients had multi lesion were 118(59%) and solitary lesion had 82 (41%), most patients had benign lesion were 150 (75%) and malignant lesion were 50(25%), study confirmed that there was statistically significant correlation between age and margins (p-value = 0.00), vascularity (p-value = 0.003) and there was statistically insignificant correlation between age and capsule, number of lesions, between gender and margins, capsule, vascularity, number of lesions and between weight and margins, capsule, vascularity, number of lesions (p-value > 0.05). there was statistically insignificant correlation between age, gender and echogenicity (p-value > 0.05), there was statistically significant correlation between calcification and type of lesion (p-value =0.001), there was statistically significant difference in margins (sig=0.001), in vascularity (sig=0.00) .The study concluded that the most patients had benign lesion, there was statistically significant correlation between age and margins, vascularity, between calcification and type of lesion, there was statistically significant difference in margins, in vascularity, and in calcification between benign and malignant lesion and there was statistically insignificant difference in capsule and echogenicity between benign and malignant lesion.

Road accidents have been considered to be one of the primary causes of mortality and lifelong disability in the early decades of life in different countries, and road traffic injuries (RTI) have been identified as the ninth most common cause of disability adjusted life years (DALYs) lost for all age and gender categories. Multi-Detector Computerized Tomography( MDCT) scanners are widely used because they rapidly produce high-resolution scans of large areas, offering short examination times for multiple body regions under emergency conditions. A retrospective descriptive quantitative hospital based study conducted in 2522 patients their ages ranged (1-80) , aimed to assess RTA trauma in Saudi Population in Najran province (KSA) in King Khalid Hospital, using CT scan . Statistical analysis of the data was performed using the Microsoft Excel. The study found that there were 2295 males (91%) 227 females (9%), were effected by RTA , age group (21-30 years) which signified 1011(40.1%.), were frequently affected, spine and head were more affected and reported (980) (38.9%) , (692) (27.4%) respectively .The conclusion of the study achieved that CT imaging plays a major role in diagnostic workflow in the evaluation of patients with trauma those usually have simultaneous injuries to several anatomic regions or organs, it can decrease the serious time and increase survival.

The accurate gestational age is critically important for pregnancy management from the first trimester to delivery, and is particularly necessary for determining viability in premature labour and in post-dates deliveries. Prior to the widespread use of ultrasound, caregivers relied on a combination of history and physical examination to clinically determine gestational age. Ultrasound gave clinicians a method to measure the fetus and therefore to estimate gestational age. This was across section study to evaluate the gestational age measuring the Occipito Frontal Diameter in the second and third trimester of pregnancy, and correlate with the gestational age estimated by Last Menstrual Period, Biparietal Diameter and Femur Length. 483 Sudanese Pregnant women underwent routine sonographic examination at different antenatal care units at Khartoum state using 3.5MHz curve liner transducer; The Occipito Frontal Diameter is measured perpendicular to the Biparietal Diameter. The statistically significant strong relationship between OFD and GA. Gestational age can be depicted by the following equations: GA=3.663+ (.286*OFD) with SR=2.882. Measuring of OFD was useful for the assessment of gestational age. Accurate prediction of gestational age was obtained by combination of different parameters.

The values of normal transverse (interpedicular) and sagittal (midsagittal) diameters are different at various levels of lumbar spinal canal in individuals of the same race and differ at identical levels in individuals of various races. The aim of the study was to determine normal reference range of the lumbar spinal canal dimensions and to evaluate lumbar pedicle dimensions with respect to spinal level, age, gender in Saudi population by using Computed Tomography. This study was conducted in Najran province (K.S.A), archival abdominal CT scan images from PACS in hospitals were used. The data of this study was collected from 210 (102 male and 108 female) normal Saudi adults individuals with different ages, gender over a period of 20 months (2019 - 2021). The mean spinal canal transverse distance (SCTR) showed steady decrease from L1 to L4, as there was an increasing in (SCTR) at L5 relative to L4, The mean spinal canal anteroposterior diameter (SCAP) showed a decrease from L1 to L3, and then a gradual increase from L4 to L5 (Fig.4-10). This pattern was observed in males only as there was an increase of female (SCAP) at L2 and L5, and no significant gender difference was noted at any lumbar level for (SCAP) The mean pedicle width (PW) showed steady increase from L1 to L5. While the mean pedicle height (PH) showed a gradual decrease from L1 to L5. The study conclude that Computed tomography is a reliable method for determining the morphological measurements of the spinal canal and pedicles diameter.
