ABSTRACT The study was carried out in three government hospitals in Enugu metropolis. It was carried out to assess the level of awareness and attitude of emergency physicians towards the use of CT in patients with head injury. Questionnaire was the major instrument for data collection. The study sought to assess the reasons for the non regular request of CT scan for patients with head injury in view of the low diagnostic yield of skull x-ray traditionally requested for such cases. The re...
ABSTRACT Slug flow along slightly inclined horizontal pipes is a major problem in gas-liquid transportation, it is very pronounced in chemical, oil and gas processing industries. In reality, there is no absolute horizontal pipe due to the undulating nature/ Topography of the laid pipe terrains. Very little research has been done in this area because of lack of experimental data. This work is proposed to use raw experimental data from 10 degrees inclined horizontal pipe to analyze the flow pr...
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...
Despite its clinical application, computed tomography scan is not readily available in developing countries, like Nigeria. Some patients who require CT examination are either managed blindly, or do not present for it at the appropriate time. This study assesses the referral pattern, indications and results of CT referrals, as they are obtained in University of Nigeria Teaching hospital Ituku/Ozalla, Enugu. Retrospectively recorded data of all patients who presented for CT scan between May 2...
ABSTRACT Background: Computed tomography has become an important tool in medical imaging to supplement conventional x-rays examination and ultrasonography. Aim: To describe the pattern of abdomino-pelvic computed tomography findings in the adult Nigerian population. (A case study EKO Hospital, Ikeja). Patients and Method: A retrospective study of 195 patients who underwent CT scan at EKO hospital, Ikeja between January, 2011 to March, 2012 was conducted. Statistical Package for Social Science...
Abstract The aim of this study was to study the cardiac diseases using Multi slice computed tomography (MSCT) and to determine the diagnostic value of (MSCT). Patient underwent MS CT study for coronary artery angiography and calcium scoring test by using axial and 3D image.135 Sudanese patients (73 males and 62females) their ages ranged (16-80) years were enrolled in the study in National Rebat Hospital Omer Sawi complex and Royal diagnosis center in the period from (2016-2018). Exclusion cr...
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...
ABSTRACT The aims of this study were to evaluate liver measurements (linear, volume) and texture on computed tomography scan, to test their reflection in interpretation of the pattern of liver enzymes abnormality and to assess the ability of laboratory tests and liver imaging tests to detect hepatic diagnosis. Prospective study of 100 patients (41 males & 59 females) with ages ranged between 25-85 years was conducted at Royal diagnostic center during the period extended from June 2014 to Jul...
ABSTRACT The aim of this study is to estimate computed tomography (CT) dose levels for common CT examinations in North-Central Nigeria. Dose parameters and scan parameters for the most commonly performed CT examinations (head, chest and abdominal CT scans) were surveyed during a four month period in 4 CT centres with Multislice scanning capabilities (4- 64 slices). Data on CT volume index (CTDIvol) and dose length product (DLP) displayed on scanner console was recorded for a minimum of 10 ave...
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...
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...
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 radiologist...
The caudate lobe is an independent anatomical region in the liver. It also shows different patterns of variability in different populations and Caudate lobe/Right lobe ratio is important for diagnosing. Knowledge and awareness of these variations are useful for Clinicians for the diagnosis and management of hepatic disorders. The aim of this study was to characterize the normal caudate lobe shape, location, texture and size in Sudanese population by using computed tomography. The study ...
Abstract Anatomical variations in paranasal sinus may differ among the different ethnic groups. And it is important to recognize the clinical and surgical significance of these variations. This descriptive study was conducted at Khartoum - Sudan to evaluate anatomical variants of paranasal sinus region.100 images of Computed Tomography for paranasal sinus (61females and 39males) were evaluated in both axial and coronal plane, nasal septal deviation, haller cells, onodi cells, and aggar cells...
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...
