Abstract The study was conducted in Sudan heart centre and Modern Medical Centre in Khartoum state-sudan from may 2015 to may 2016 the data collected in Radiology Department from patients files and analysis by SPSS. A descriptive study designed to detection of lung abnormalities using High Resolution Computed Tomography in diagnosis lung disease which cause chest pain, shortness of breathing and other signs and symptoms related to respiratory system and to correlated the findings to age, ge...
Abstract Computed tomography (CT) is an imaging technique which produces a digital topographic image from diagnostic x-ray. It always considered a “high dose” technique, there is growing realization that image quality in CT often exceeds the level needed for confident diagnosis and that patient doses are higher than necessary. The aim of this study was to evaluate the level of radiation dose received by the patients during brain and abdomen CT examination. In this study, a total of 128 a...
ABSTRACT The aim of this study was to characterize stroke lesions and normal brain tissue in computed tomography (CT) images of Nigerian patients using statistical texture descriptors, and to identify the class of texture descriptor that is most suitable for computer-aided diagnosis of stroke. Non-contrast CT images of 164 stroke patients were obtained in contiguous slices from the base of the skull to the vertex from two private radiodiagnostic centres. Initially, two experienced radiologis...
The purpose of this descriptive cross sectional study was to evaluate the computed tomography findings of the brain in patients with headache. The study used (85) patients with headache who underwent a computed tomography scan of the brain in Amal National Hospital, the sample contained both gender (38 males and 47 females). Patients were examined in this study, ranging in age (18-65 years old) with the predominant age group (26-35 years), which accounted for 40% of the sample. All pati...
The extra axial brain hemorrhage causes mortality when not early diagnosed and treated. The study aimed to evaluate the extra axial brain hemorrhage using computed tomography. Collcted all the patients from Ibrahim Malik Hospital from march to may 2016 .Non contrast computed tomography was done in all patients . The result from 60 patients with different age and gender diagnosed as extra axial brain hemorrhage.In this study peak incidence was among the age between (41-50 year),(63.3...
Abstract Esophageal cancer is the third most common gastrointestinal malignancy and is among the 10 most prevalent cancers worldwide (Beasley P. 1997) . the main objective of this study to Assessment of Sub- mucosal Layer Spread of Esophageal Carcinoma using computed tomography . which done to the 35 patients with histologically confirmed esophageal carcinoma ,referred to Alamal Hospital and Alneleen Medical Center, for determine the accurate site and size of tumor for possible treatment from...
Computed Tomography and Childhood Seizure Disorder in Ibadan Background: Computed Tomography (CT) is an important tool for neuroimaging, it offers an opportunity to investigate structural lesions as a cause of seizures with little morbidity. This study is designed to evaluate it’s applicability in children with epileptic seizures. Method: It is descriptive study of the CT scans of the 103 consecutive children who were referred to the CT suite of the University College Hospital on account o...
ABSTRACT Computed Tomography (CT) is a valuable tool among diagnostic imaging modalities. However, the increase in its utilization has resulted to a considerable increase in its contribution to the collective dose from medical exposure. The main aim of this study was to propose a patient dose optimization method from exposure parameters that would estimate the peak skin doses (PSDs) to patients undergoing chest CT and abdomen CT examinations. PSDs were estimated on the surface of a Perspex C...
ABSTRACT The aim of this study is to estimate the effective dose and assess the lifetime attributable risk of cancer incidence of patients undergoing computed tomography scan at the KorleBu Teaching Hospital. Data on Volume CT Dose Index ( ) and Dose Length Product ( ) displayed on the scanner control console was recorded after confirmation of the results by performing independent checks on a phantom. The effective doses were estimated using the displayed and the anatomic region specific co...
Computed Tomography (CT) is a Iife saving tool for diagnosing Illness and injury in children (0 - 12 years). The use of computed tomography scan of the head, abdomenlpehris, chest or spine in children has increased were the last three decades [I]. Approximately 5 to 9 million CT examinations are performed annually on children in the United States 121. The increased use of CT in pediatrics, combined with variability in radiation doses, has resulted in many children receiving a high dose of rad...
ABSTRACT The main objective of this work is to assess the integrity of structural shielding to validate the protection of the staff and the public for two selected general radiography and CT facilities. The assessment for general radiography was based on 729 examinations for facility A and 706 examinations for facility B. For computed tomography (CT) rooms, a total of 293 body and 190 head procedures were used for facility A, and 195 body and 160 head procedures for facility B. For general ra...
ABSTRACT This study was to examine procedures used to estimate radiation dose delivered to adult and paediatric patients undergoing computed tomography (CT) examination and propose alternative and more efficient ways to establish body CT protocols for optimum protection of patient for clinical use. Automatic exposure control (AEC) and fixed tube current (FTC) techniques were used for Polymethylmethacrylate (PMMA) dosimetry phantoms in a Siemens emotion 16-slice multidetector computed tomograp...
