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 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 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...
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...
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...
Sex estimation models are specific to populations and cannot be generalized due to genetic and environmental variabilities. This retrospective cross-sectional study, conducted between January and September 2023 at the Tamale Teaching Hospital, included 119 (50.9 %) females and 115 (49.1 %) males aged 23–82 years. Measurements, including manubrium length (M), manubrium width (MW), sternal body length (B), combined manubrium and sternal body lengths (CL), corpus sterni width at first sternebr...
The study determined bony labyrinthine anomalies in a group of children with severe and profound hearing loss.
ABSTRACT Radiation absorbed dose for patients undergoing myocardial perfusion has been calculated for technetium-99m Hexakis-2-methoxy-2-methylpropyl-isonitrile (99mTcSestamibi) at the Nuclear Medicine Department of Abdou Moumouni University. Thirty patients were scanned and image quantification was achieved using MedisoInterViewXP® software. An activity of370 MBq (10 mCi) of 99mTc-Sestamibi was administered for stress and 1110 MBq (30 mCi) for rest. A 256 x 1024 matrix size and a speed of ...
Abstract This study was aimed to study the temporal bone diseases using HRCT. Data was obtained retrospectively from 52 patients of different ages and gender who are selected from ENT hospital and clinically suspected of having symptoms related to the temporal bone such as ear discharge, conductive hearing loss, vertigo and facial palsy. traumatic patients were excluded. The study was done at Alzaytouna specialist hospital&Antalya medical center during 2016 year. HRCT images were obtained by...
ABSTRACT Recently measuring of stroke volume by scintigraphy has been used as indicator of heart muscle ability to contract. This study aimed to identify and evaluate the stroke volume. Accordingly the data was collected from 50 patients at Elnilein medical center, department of nuclear medicine, during the period from 4/4/2011 to 24/8/2011. The patients were injected with a 99mTc-sestamibi (hexakis [2- methoxyisobutylisonitril]) and 99mTc-tetrofosmin (1, 2-bis [bis (2-ethoxyethyl)- phosphino...
Abstract The study was done to characterize foramen magnum using CTs and effect of diameter of base of the skull and height of patient on the diameter of foramen magnum. 50 patients (60% males and 40% females) were selected all the diagnosis as normal cranial CTs. This study was done in Abdoon SidAhmed Diagnostic Center and Alfaisal Specialized Hospital during the period from January to Marsh 2016. This study found the mean anterior posterior diameter FM in male subjects as 37.41mm (±3....
ABSTRACT To determine the liver CT number among Sudanese people using spiral CT. A designed data sheet was used to collect data from 50 patients refer to CT abdomen , which was done using images of slice thickness (5mm) and slice gap (7-10mm) , three readings were taken from three points in axial cuts. The mean CT number of liver among the males was found to be 57.24±7.98 HU , and that among females was 56.19±10.77 the mean different was found to be 1.05 which was statically insignificant ...
ABSTRASCT:- This descriptive study, conducted in the state of Khartoum in the period from April 2016 till October 2016 Hospital Zitouna International Specialist, by checking researcher random sample of Sudanese patients and of 50 patients aged between 32 and greater than 65-year-old goal of a researcher in this study to measure the dimensions of liver Sudanese taking four dimensions the following the measurement of the human liver, , the anterior posterior dimension of the left hepatic lobe ...
