Objective: This is a retrospective and cross-sectional-analytical design study aimed to estimate the radiation exposure dose for adult patients undergoing chest and abdomen CT examinations at Khartoum state hospitals. Material and Methods: Using Size-Specific Dose Estimates (SSDEs) to investigate the effect of body dimensions (Deff) on SSDE calculated from transverse or scout CT images. Scan parameters were collected for 330 adult patients with 165 chests and 165 abdomens for 161 f...

Purpose and Objectives: As any health study generally aims to contribute to the improvement of the state of the health of the population, this one tries to respond from a particular angle to the improvement of the health of the personnel of the health sector. Radiology by combating the risks is associated with X-rays (RX). So this study aims to help promote greater safety in the use of X-rays in hospitals in the city of Mbujimayi while highlighting the shortcomings in terms of radiation protecti...

Objective: This article aims to assess whether or not medical students from Louisiana State University School of Medicine-Shreveport supported the idea of adding ultrasound training into the current medical school curriculum, while also highlighting the current knowledge and confidence these medical students had when performing ultrasound-guided procedures. Materials and Method: After completing a trial of the SonoSim system, 28 fourth-year medical student volunteers were assessed for current co...

The objective of this study was to describe the variations in human pulmonary fissuration in a cadaveric Kenyan population. Data were collected from 48 formalin-fixed cadavers in the department of Human Anatomy, University of Nairobi, Kenya; with 38 right and 32 left lungs meeting the study’s inclusion criteria. The fissures were studied irrespective of the cadaver’s sex and were classified anatomically as proposed by Craig and Walker (1997). Out of the 38 right lungs examined, the horizontal fi...

The main goal of the article is to compare the effective radiation doses received by the leading interventional cardiologist during the angiographic procedures. A comparison is done between the dose load during three procedures—LAD-stenting, LCx-stenting and RCA-stenting. An angiographic X-ray system Philips Allura Xper FD10 (with G-arm) was used for this study. The dose obtained was measured with an X-ray-Gamma Dosimeter 27091. The dose measurements were made for the respective projections of e...

This article is a continuation of the study of the dose load received by an interventional cardiologist during angiographic procedures and particularly during RCA stenting. To calculate the dose load, dosimetric measurements of the effective dose were carried out while working with a Philips Allura Xper FD10 angiographic system in the invasive department of the Special Hospital for Active Treatment in Cardiology, Varna, Bulgaria. The measurements were carried out for the two operating modes of t...

The study of the dose load received by the personnel working with x-ray equipment is a very important task in the modern world. The purpose of this article is to assess the dose load based on published dosimetric measurements obtained by an interventional cardiologist from scattered X-ray during the angiographic procedure LCx stenting. The procedure is carried out under X-ray guidance using a Philips Allura Xper FD10 system. The dose calculations and assessments are made for three positions of t...

Based on published dosimetric measurements, the dose load received by the interventional cardiologist from scattered X-ray radiation was assessed for an angiographic LAD stenting procedure under X-ray guidance. An angiographic X-ray system “Philips Allura Xper FD10” was used for the study. The dose assessment calculations were made for three positions of the patient table—basic, lowest and highest—and for three measurement points—“head”, “gonads” and “feet”, in which the received dose was measur...

Ascaris lumbricoides is the most common helminth affecting humans. It is endemic in tropical and underdeveloped countries. It particularly infects children but most often is asymptomatic. Sometimes, it can mimic a surgical abdominal emergency. When it is suspected, its diagnosis is made on the parasitological examination of stool. We here report the case of a diagnosis of intestinal ascariasis made on ultrasound in an 8-year-old child who consulted for an acute abdominal syndrome which initially...

CT technology has been widely used in various fields such as medical treatment, industry, and materials. Recently years, cone-beam CT (CBCT) used in the medical field is replacing the traditional spiral CT slowly due to its unique advantages. Improving the performance of CBCT and the image reconstruction algorithms could obtain higher quality of images, meanwhile, these also reduce the exposure time of X-ray irradiation. And image reconstruction techniques based on sparse angles have benefits fo...
