This study sought to equip clinician’s on the imaging modality of choice between CT and MRI in the diagnosis of brain tumor. The comparison of the two imaging modalities was accessed using biopsy as goal standard. This research study involved 40 patients who underwent CT, MRI and biopsy one at a time in National hospital, Abuja. Data were collected via secondary source using patient’s folder; hospital records. The result revealed that MRI which has an accuracy, sensitivity and specificity...
CHAPTER ONEINTRODUCTION1.0 BACKGROUND OF STUDYMedical diagnosis, (often simply termed diagnosis) refers both to the process of attempting to determine or identifying a possible disease or disorder to the opinion reached by this process. A diagnosis in the sense of diagnostic procedure can be regarded as an attempt at classifying an individual’s health condition into separate and distinct categories that allow medical decisions about treatment and prognosis to be made. Subsequently, a diagno...
ABSTRACT 206 patients clinically diagnosed as stroke/cerebrovascular accidents (CVA) were investigated using computerised tomography (CT) scan.
Abstract The computerized tomography have a role in diagnosing head injuries .Objective of this study was to studyhead injuries by using Computerized tomography .This study is done in Khartoum state in C.T department in Ibrahim Malik teaching hospital study was carried out in 54 Pts males and females aged (1-80 years) during January - March 2016, The study is concerning patients with head injuries the incidence of the head injuries is higher in males rather than females, and the occurrence h...
ABSTRACT Advance in medical diagnostic technology induced accurate diagnostic for most of disease especially abdominal ones, the main objective of the study was to assess renal change in diabetic patient using CT, in fact diabetes is the most common cause of kidney failure, diabetic nephropathy begins silencet before patient having symptoms and early discovery of it may slow down kidney damage. This study was done for 40 diabetic patient (34 male and 16female) all of them have diabetes melli...
ABSTRACT This research study was aimed at performing dosimetry intercomparison on different CT scanners in the diagnostic radiology departments of Korle-Bu Teaching Hospital (KBTH), Sweden Ghana Medical Center (SGMC) and Global Medical and Imaging Center (GMIC).Using the standard body phantom and integrated ion chamber technique volume computed tomography dose index (CTDIvol) and Dose-Length Product (DLPs) within the phantom were evaluated. The ion chamber technique was applied to two 16 slic...
ABSTRACT Background: Even with newer and repurposed anti-TB drugs almost a third of patients with XDR-TB have unfavourable outcomes. In patients with localised disease and adequate pulmonary reserve, surgery is an important adjunctive treatment. However, there are no outcome data from TB endemic countries, and the prognostic significance of pre-operative PET-CT findings remains unknown. Objectives: To report outcomes for resectional surgery in our setting, and to study whether PET acti...
ABSTRACTTransvaginal sonography is a later addition to the diagnostic techniques available for the evaluation of the female pelvis and can overcome many of the limitations of traditional transabdominal scanning. Transvaginal sonography involves the placement of the probe within the vagina. This is uncomfortable for most women especially in this part of the world where ethical issues are now a challenge. This may reduce the practicability of transvaginal sonography. There is also reluctance in...

ABSTRACT Fusion of medical images between different cross-sectional modalities is widely used, mostly where functional images are fused with anatomical data. Ultrasound has for some time now been the standard imaging technique used for treatment planning of prostate cancer cases. While this approach is laudable and has yielded some positive results, latest developments have been the integration of images from ultrasound and other modalities such as PET-CT to compliment missing properties of u...
Abstract The geoid is an equipotential surface which coincides on the average with the mean sea level has significant relevance in geodesy, surveying and other earth related disciplines.This thesis focuses on the digital terrain modeling (DTM) technique based on geometrical interpolation approach by fitting a surface that depends on the reference points that are chosen in the critical and characteristic locations of the field to represent the trend of the surface. Using the orthometric heigh...
Abstract Computed tomography CT, is a diagnostic medical test that produces multiple images of the inside of the body. CT images provide greater details of soft tissues and blood vessels. A cardiac CT scan for coronary calcium is a noninvasive screening study for obtaining information about the presence, location and extent of calcified plaque in the coronary arteries. This study was performed in the Radiology department of the Royal Scan center and the Royal Care International Hospital in K...
Abstract In this work we apply a finite volume discretization technique based on a relaxation scheme to simulate the morphological evolution of the topography as a result of a dam break, that causes flooding downstream of the breach location. The considered mathematical model comprise of shallow water equations coupled with the bed updating equation which is modified to account for sediment entrainment process. Thus the model comprises a set of highly nonlinear hyperbolic partial differentia...
Abstract Hydrocephalus is the common disease which effects pediatric and elderly people. many studies are usually used to detect this disease. This research aimed to study the hydrocephalus using the computed tomography (CT) modality. The study was carried out at Yastabshiroon Hospital and Police Central Hospital in Khartoum, during the period from October 2016 to January 2017.A random sample of 50 patients (21 males and 29 females) with different ages was included in the study. The patients...
Abstract Supernumerary kidney is a rare congenital anomaly of the urinary system with less than 100 cases documented in literatures worldwide'>'. Very rarely documented is the fused supernumerary kidney and horseshoe component with unknown incidence, due to the rarity of this complex anomaly. We hereby present a rare case of complex renal anomalies of fused supernumerary kidneys with horseshoe component misdiagnosed as an abdominal tumour on ultrasound, incidentally discovered at Computed To...
