Strategy of computed tomography image optimization in cervical vertebra and neck soft tissue in emergency patients
Introduction: Due to the use of ionizing radiation in the CT scan, optimal parameters should be used to reduce the risk of cancer in patients who are constantly exposed to X-rays. The aim of this study was to optimize the parameters used in CT scan of cervical vertebrae and neck soft tissue with minimal loss of image quality Materials and Methods: In this s...
متن کاملAutomated outcome classification of emergency department computed tomography imaging reports.
BACKGROUND Reliably abstracting outcomes from free-text electronic health records remains a challenge. While automated classification of free text has been a popular medical informatics topic, performance validation using real-world clinical data has been limited. The two main approaches are linguistic (natural language processing [NLP]) and statistical (machine learning). The authors have deve...
متن کاملRadiation doses to emergency department patients undergoing computed tomography.
OBJECTIVES Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. METHODS We conducted a hea...
متن کاملTrends in computed tomography utilization in the pediatric emergency department.
OBJECTIVE The purpose of this study was to determine the overall trend of computed tomography (CT) utilization in the pediatric emergency department (PED) from 2003 to 2010 and to determine trends categorized by common chief complaints. METHODS Electronic chart records at 2 tertiary care PEDs within a large pediatric health care system were reviewed from January 2003 through December 2010. Th...
متن کاملDose Reduction Methods in Chest Computed Tomography
Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...
