Study Of Computed Tomography Findings Of Lumber Spine Injuries

Abstract Lumbar spine injuries continue to be an enormous public health problem even with modern medicine in the 21 century. Most patient mild stage, the remaining injuries are divided equally between moderate and severe categories. This study is statistical study, but through it the researcher reflected the social and economic impact of lumbar spine injuries. The main purpose of this study is to estimate variety and severity of lumbar spine injuries. This received in some CT diagnostic cent...

Study of Cerebral Strokes using Computed Tomography in Sudanese People

Abstract The stroke is a medical emergency in which the blood supply to any portion of the brain is interrupted or reduced, alternative names: Cerebrovascular accident/ disease (CVA), cerebral infarction, cerebral haemorrhage. This study is a descriptive study and had been conducted at police hospital in a period from October 2016 to January 2017 with sample which was consisted from 50 patient CT brain images for patient having cerebral stroke. The aim of this Research to study of cerebral s...

Detection Of Liver Diseases In Computed Tomography Scan Images Using Artificial Neural Networks

ABSTRACT Liver is one of the most important organ in the human body, it performs a variety of vital functions. Liver cancer is a pathological disorder of the human that affects around 50 million people worldwide. The early detection and diagnosis of liver cancer is very important to facilitate the treatment process. The objective of this study is to design and develop an automated system for liver CT images diagnosis as normal or abnormal to help physicians in their diagnosis and treatment p...

Optimization Of Radiation Dose And Image Quality In Computed Tomography Imaging

Abstract Improvements in the benefit of CT have been so dramatic that a tendency exists to the overuse. CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures. While the benefits of CT exceed the harmful effects of radiation exposure in patients, increasing radiation doses to the population have raised. The main objective of this work was to find an optimization approach to minimize the radiation dose to adult patients undergoing CT ex...

Evaluation of Liver Tumors using Computed Tomography

Triphasic liver CT enables characterization of a wide range of focal liver lesions.  The general objective of the study is to evaluate the role of CT in diagnosis of liver lesions. And furthermore to determine which lesion in the liver with high incidence, and to find out the geographic distribution of the liver lesions in Sudan. Sixty patients found to have focal tumoral liver lesions were recruited for 4 months period and their triphasic CT scans findings were evaluated and later correlate...

Determination of Normal Splenic Dimensions on Computed tomography Images in Sudanese Population

Spleen is enlarged in a variety of clinical conditions including infectious, infiltrative, immunologic and malignant states. Evaluation of splenic size is important in every physical examination of the abdomen by a physician.Determination of its size by palpation can be extremely inaccurate because spleen is never palpable till it is enlarged 2 to 3 times its own size. The accurate diagnosis of splenic enlargement is a matter of considerable importance as it is a useful guide for arrivin...

Study of anatomical variations of the sphenoid sinus among Sudanese using Computed Tomography

With the expanding use of the functional endoscopic sinus surgery (FESS), proper understanding of the sphenoid sinus anatomy has become increasingly important. Knowledge of the size and extent of pneumatization of sphenoid sinus is an important to avoid any complications during surgery. This descriptive study was conducted in Sudan - Khartoum to study the anatomical variations of sphenoid sinus among Sudanese using ct scan. 70 images of ct for para nasal sinus (35males and 35females) we...

EVALUATION AND VALIDATION OF COMPUTED TOMOGRAPHY DOSE ACCURACY (CTDIw AND CTDIvol)

ABSTRACT Weighted and average dose within a scan volume of a phantom have been evaluated and validated using two different devices and techniques. The Barracuda electrometer and Ion Chamber techniques were applied on a 16 slice Siemens CT scanner and the results compared to the console displayed CTDIw and CTDIvol valuesfor accuracy and compared to each other for validation purposes. With fixed exposure parameter of 130kVp and varying tube current-time products from 140mAs to 300mAs for the ...

Assessment Of Renal Values In Healthy Sudanese Adult Population Using Computer Tomography

ABSTRACT This is descriptive study was conducted in three six during the period from JUNE 2018 to OCTOBER 2018 in Alribat Diagnostic Hospital. The aims of this study were to evaluate normal renal measurements in Sudanese adults using Computed Tomography and correlated to age and gender and BMI This study carried out in a sample of 50 patients (25 males and 25 females) who underwent to Computed Tomography examination for different reason. The main results of this study were that mean and stan...

Optimization of Radiation Dose for Brain Computerized Tomography

Abstract: This study was conducted to evaluate the effective dose in adults during the examination of the brain computed tomography. The motivations for this study that frequency of the brain CT test is high and the radiation field of brain CT contain sensitive organ like eyes. By mathematical equation after it has been collecting the factors that affect the amount of radiation from producer ray tube in addition to the two factors CT radiation dose index (CTDI) and the dose length product (D...

Computed Tomography(CT) Radiation Dose in Children: A Survey to Propose Regional Diagnostic Reference Levels in Accra, Ghana

ABSTRACT The aim of this work was to assess the doses delivered to paediatric patients during computed tomography (CT) examinations of the head, chest and abdomen, and establishing regional diagnostic reference levels (RDRLs) for four age groups. The patient data, technique parameters and dose descriptors collected include: age, sex, tube voltage, tube current, rotation time, slice thickness, scan length, volume CT dose index (CTDIvol) and dose length product (DLP). Currently, paediatric CT ...

NECROTIZING FASCIITIS OF THE ANTERIOR ABDOMINAL WALL: A RARE COMPLICATION OF NEGLECTED STRANGULATED RICHTER'S EPIGASTRIC HERNIA

Necrotizing soft tissue infection (NSTI) is an aggressive and rapidly spreading soft tissue infection that could be associated with high mortality. Early diagnosis can be challenging and so a high index of suspicion is needed. Bedside ultrasonography (USG) and computed tomography (CT) scan could be employed to aid in diagnosis. The objective of this report is to describe the diagnostic process in a resource challenged setting and review the literature. We present an elderly patient with necro...

DESIGN AND IMPLEMENTATION OF A MEDICAL DIAGNOSTIC SYSTEM

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...

Determination Of CT Number Of Normal Spleen In Sudanese Population Using CT Scan

Abstract The objective of this study was to determine the normal spleen in Sudanese population using computed tomography (CT) scan by measuring the normal spleen, liver and vertebrae CT number as well as to correlate the spleen readings with patients age, gender and race as well as to correlate the spleen readings with liver and vertebrae CT numbers in order to find out the normal standard value as local refrence for Sudanese and to compare the findings with other population and literature. ...

The study of Hydrocephalus by using CT Scan in Sudanese population

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...
