BACKGROUND Lumbar spine radiography has limited diagnostic value but low radiation dose compared with computed tomography (CT). The average effective radiation dose from lumbar spine radiography is about 1.1 mSv. Low-dose lumbar spine CT may be an alternative to increase the diagnostic value at low radiation dose, around 1 mSv. PURPOSE To determine the optimal settings for low-dose lumbar spi...

Muhammed Alshamari (2016): Low-dose computed tomography of the abdomen and lumbar spine. Örebro Studies in Medicine 137. Radiography is a common radiologic investigation despite abundant evidence of its limited diagnostic value. On the other hand, computed tomography (CT) has a high diagnostic value and is widely considered to be among the most important advances in medicine. However, CT expose...

BACKGROUND Primary care requests for radiographs of the lumbar spine have come under increasing scrutiny. Guidelines aiming to reduce unnecessary radiographs by limiting referrals to patients at high risk of serious disease have been widely distributed. Trial evidence suggests that guidelines can reduce radiography referrals. It is not clear whether this reduction has been achieved in routine p...

Background and purpose: Estimation of the risks of radiation would be possible by identifying the dose received. Introducing the dose level from diagnostic procedures can be effective in reducing the patient dose, improving the quality of treatment, and increasing the safety of patients and staff. This study evaluated patient entrance surface dose (ESD), effective dose, and cumulative dose from...

Objective To test the hypothesis that radiography of the lumbar spine in patients with low back pain is not associated with improved clinical outcomes or satisfaction with care. Design Randomised unblinded controlled trial. Setting 73 general practices in Nottingham, north Nottinghamshire, southern Derbyshire, north Lincolnshire, and north Leicestershire. 52 practices recruited participants to ...

Introduction: Collimating the primary beam to the area of diagnostic interest (ADI) has been strongly recommended as an effective method to reduce patient’s radiation dose and to improve image quality during radiology practice. Lack or inadequate collimation results in excessive radiation dose to patients and deterioration image quality.Objective: To assess the quality of beam collimation dur...

purpose many factors such as lumbar instability and spinopelvic alignment are associated with low back pain. our purpose was to analyze the pelvic incidence - one of spinopelvic alignment parameters- and spine instability correlations in patients with chronic low back pain. methods fifty-two patients suffering from chronic low back pain entered this case control study. lateral spine radiography...

Introduction: Nowadays, we are witnessing a progressive application of radiology techniques in various communities as well as in Iran. Medical radiological examinations are one of the important sources of public radiological dose. Entrance skin doses and effective doses for patients in diagnostic radiology examinations should be assessed for the imaging techniques optimization and patient&rsquo...

BACKGROUND Lumbar spine radiography has limited use in diagnosing the cause of acute low back pain. Consensus-based guidelines recommend that lumbar spine x-rays are not used routinely. However there have been no studies of the effect of referral for radiography at first presentation with low back pain in primary care. AIM To compare short and long-term physical, social, and psychiatric outco...

Background: The basic challenge with computed radiography (CR) systems is the large dynamic range which provides an opportunity for radiographers to gradually increase exposure factors and still produce good image quality, a practice that can lead to dose creep. Materials and Methods: The aim of this study was to establish  the entrance skin dose (ESD) values for nine selected examinations in t...
