The aims of the study is to investigate the role of Magnetic Resonance Imaging in classification and grading of mycetoma disease, the study was conducted at the center of Mycetoma Research -Khartoum University during the period 2018-2022.
The study deals with the patients of mycetoma disease transferred to Magnetic Resonance Imaging department in FADIAL hospital, ANTALIA diagnostic center and DAR AL-ELAJ hospital.
The study covered 150 patients including both genders 88.7 % male and 11.3 % female the sample is ranged between 10 years up to 62 years.
The MRI evaluated and the data were collected through a questionnaire contains the manifestation of the disease on Resonance Imaging by radiologists.
The data were analyzed by using SPSS program (Statistical Package for the Social Sciences) version 26 and excel program.
Categorical data were presented as frequencies, percentages and the result were displayed as tables and figures.
The result shows that males are more affected with disease than female with percentage of 88.7% the age is ranged between 21-31 years was more affected with percentage of 42%.
The spots were appeared in all images with prominent appearance 69.7% percentage.
Inlets sinuses appear is shown in 45% from the sample, otherwise bone destruction appearance is highly frequented in the data with percentage 75.7 %.
The ability to grading the disease with MSMB (Mycetoma Skin, Muscle and Bone System) had percentage of 100% that’s mean the new grading system was done with all the samples.
The study conduct that Magnetic Resonance Imaging had great value in grading mycetoma disease but on the other hand it’s not main role in classification between types that causing mycetoma disease.

Assessment of digital x-ray machine image quality using quantitative analysis

Introduction: The physicians and radiography specialist are concern to image quality that reveals the pathology and hence the proper management of the patient condition and be satisfied; this situation mostly lead to high dose given to the patient where if the image quality was not suitable so repetition of the imaging process is mandatory. This study includes the significant increase of image quality and the new potential for dose reduction. It intends to assess digital x-ray machine image quality using quantitative analysis for five organs; Feet exam, breast exam, Pelvic exam, Spinal exam and chest exam in police Hospital in Sudan in Khartoum State. Statement of the problem: The evaluation of x-ray using quality mostly done subjectively, using visual perception which gives unreliable result these true of quantitative methods were applied more accurate results can be obtained and hence correlation of problem will be most accurate. Purpose: this study aimed to assessment of digital x-ray machine image quality using quantitative analysis. Material and method: A total of 100 patients from both male and female were randomly selected from whom exposed their Feet, breast, pelvic, spinal or chest to digital X-ray machine, from Neusoft in Police Hospital in Khartoum State. Region of interest (ROI) were selected from the image using 3×3 pixels in the high intensity and low intensity region on the same image then data were extracted from these region as signal, noise, signal to noise ratio, contrast before and after image enhancement using histogram equalization function; where distribution of image intensity histogram were redistributed for better image quality in respect to visual perception. In X- ray imaging the exposure parameters used are selected according to patient weight and organ size. The Standard (FFD) of 100 cm was used for all routine examination and the chest X- rays FFD of 180 cm are used for geometrical reason. The Interactive Data Language (IDL), Statistical Package for the Social Sciences(SPSS) and Microsoft Excel programs was used. Results: signal in high intensity region before and after enhancement, was 1409.66±532.08 and 1859.09±614.52; at p = 0.05 using t-test where p was <0.0001 and t = 19.2. While noise before and after enhancement did not show an increase in the high intensity area but barley it deceases it was 43.94±104.53 and 42.08±9.42 at p =0.05 where p = 0.8 and t = 0.254 also Signal to noise ratio showed and improvement before enhancement since noises were not increases and the signal arbitrary were increased after enhancement as follows: 36.99±10.30 and 42.08±9.42. linear increased by 0.95 units per each units before the enhancement starting at 7.2 This increased were significance using t-test with t = 9.717 and p <0.0001. The values of the signal and noise in low intensity areas before enhancement were 677.83±517.26 and, 41.01±142.41while after enhancement the signal and noise were 1104.65±71345 and 24.51±8.84; it increased by 0.99 unit per each unit before the enhancement starting at 6.7 units at p <0.0001 and t = 13.057 Noise also follows the same pattern where it shown direct linear relationship it increased by 0.97 units per each units before enhancement starting at 6.9 at t = 1.652 and p =0.1.
Conclusion: It concluded that the quantitative analysis is a valuable tool for digital X- Ray image estimation.

This was descriptive cross sectional study the problem of the study was that there is no specific characterization of the dimensions of the FM as standard in Sudanese population, study aimed to measure the foramen magnum in Adult Sudanese using computed tomography conducted in Northern State at Aldaman Hospital during the period from March to October 2022, The Data were collected from 100 patients using data collection sheet containing the following variables; age, gender, as well as the measurements relating to foramen magnum include FML and FMW and analyzed statistically by SPSS, their age (20-30) years (50%) males and (50%) females.
The results found that the mean of foremen magnum length was (35.05±3.11) mm, the mean of foremen magnum width was (29.15±2.52) mm, males average length was (35.4±2.32) mm and width was (29.51±2.72) mm, females average length was (34.71±3.73) mm and width was (28.79±2.27) mm, there was statistically insignificant correlation between gender and foremen magnum measurements (p-value = 0.268 and 0.153) and there was statistically insignificant correlation between age and foremen magnum measurements (p-value = 0.973 and 0.105), there was statistically insignificant difference in foremen magnum measurements between males and females (sigs. > 0.05); males measurements greater than females measurements. there was statistically insignificant difference in foremen magnum measurements between age groups (sigs. = 0.888 and 0.27), there was very weak linear relationship between age and foremen magnum length (R² = 0.0006), between age and foremen magnum diameter (R² = 0.0006) and weak positive linear relationship between age and foremen magnum width (R² = 0.025).
The study concluded that there was very weak linear relationship between age and foremen magnum length, between age and foremen magnum diameter and weak positive linear relationship between age and foremen magnum width.

Background: The third fatal coronavirus is the novel coronavirus (SARS-CoV-2) that causes novel coronavirus pneumonia (COVID-19) which first broke out in December 2019. Patients will develop rapidly if there is no any intervention, so the risk identification of severe patients is critical.
Objective: aimed to evaluate of COVID 19 by using computed tomography. Material and methods: A total of 50 patients who had Chest (HRCT) and confirmed positively with COVID-19 using real time polymerase chain reaction RT-PCR were included in this study. Results:
(44 %) were males and (56 %) were females. The age was categorized into three groups, the majority of patients infected with COVID-19 were aged 50 – 60 years old (47 %) and (43 %) have age more than 70 years old aged between 40 to 59 years. The incident of hypertension and diabetes in our patient was high (51%). Where (43 %) of total patients had moderate where (57 %) of them have severe symptoms. Study also found that COVID-19 distributed as GGOs, consolidation with a surrounding halo sign, Bilateral or local patchy shadowing and Interstitial abnormalities in 56 % of patients with COVID-19. there was no significant difference (p value = 0.691 and 0.884 < 0.05, respectively) between gender and age with both medical history and clinical symptoms of patients who infected with COVID-19 where there is a statistical difference in comparing with age groups (p value = 0.000 > 0.05). and there is a statistical difference in correlation between CT findings and age groups (p value = 0.000 > 0.05). Conclusion: Chest CT played an important role in the diagnosis and follow up of COVID-19.
