Estimating Risk Parameters

Estimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography

Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...

A System for Continuous Estimating and Monitoring Cardiac Output via Arterial Waveform Analysis

Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...

Estimating genetic parameters of agronomic and uality traits in a diallel cross of sugarbeet

Evaluation of diagnostic accuracy of RMI and ROMA indices in comparison to HE4 and CA125 parameters for estimating the risk of malignancy of adnexal masses.

Background: Ovarian cancer is the fifth leading cancer-related cause of death in women worldwide and is often diagnosed at advanced stages. Regarding the low sensitivity and specificity of the currently available diagnostic techniques, in the present study, we aimed to evaluate the accuracy of RMI and ROMA indexes and comparing these two indexes with CA-125 and HE4 parameters for the diagnosis ...

Estimating the cancer risk and mortalities induced by routine digital radiography examinations on patient of different ages in Mazandaran province

Background: The aim of this study was to estimate the cancer risks and mortalities of different types induced by routine examinations of digital radiography for one year in Mazandaran province, Iran. Materials and methods: Radiation parameters and calculated entrance skin dose (ESD) values of 13 digital radiographic examinations were collected from 2340 patients at 18 high-patient-load radiogra...
