“…We suggest using VFA as a screening tool for vertebral fractures and for routine surveillance of vertebral height (such as vertebral remodeling while on bisphosphonate therapy) [19]. Considering alternative forms of imaging, such as MRI, DXA or EOS imaging, in an attempt to avoid CT is also imperative [20]. Improvements in the medical management of patients with OI have resulted in a longer life expectancy, therefore the cumulative E from medical imaging we report becomes more relevant.…”

“…Studies have shown that EOS imaging utilizes the lowest radiation dose compared to any other full-spine modality. 16,17 Pediatric patients are at risk of receiving even higher effective doses from these imaging studies due to decreased body mass. 18 Additionally, with conventional radiographs, separate views of the abdomen and chest are necessary to obtain the same scope of visualization as with EOS, resulting in an effective dose of about 1.6 mSv (AP and lateral abdomen and chest views) with conventional radiography.…”

OBJECTIVEPatients with shunted hydrocephalus often accumulate high levels of radiation over their lifetimes during evaluation of hardware integrity. Current practice involves the use of a series of conventional radiographs for this purpose. Newer low-dose EOS radiography is currently used to evaluate scoliosis but has not been explored to evaluate shunt integrity on a large scale. The goal of this study was to compare the quality of imaging using EOS low-dose radiography to conventional radiography to evaluate shunt tubing.METHODSA retrospective chart review was performed on 57 patients who previously had both conventional radiographs and low-dose EOS images of their cerebral shunt tubing from 2000 to 2018. Patient demographics (age, sex, type of shunt tubing, primary diagnosis) were collected. Conventional radiographic images and low-dose EOS images were independently analyzed by a neurosurgeon and neuroradiologist in three categories: image quality, delineation of shunt, and distinction of shunt compared to adjacent anatomy.RESULTSAll patients had shunted hydrocephalus due to spina bifida and Chiari type II malformation. Ratings of EOS and conventional radiographic images by both raters did not differ significantly in terms of image quality (rater 1, p = 0.499; rater 2, p = 0.578) or delineation of shunt (p = 0.107 and p = 0.256). Conventional radiographic images received significantly higher ratings than EOS on the ability to distinguish the shunt versus adjacent anatomy by rater 1 (p = 0.039), but not by rater 2 (p = 0.149). The overall score of the three categories combined was not significantly different between EOS and conventional radiography (rater 1, p = 0.818; rater 2, p = 0.186). In terms of cost, an EOS image was less costly than a conventional radiography shunt series ($236–$366 and $1300–$1547, respectively). The radiation dose was also lower for EOS images, with an effective dose of 0.086–0.140 mSv compared to approximately 1.6 mSv for a similar field of view with conventional radiography.CONCLUSIONSThe image quality of low-dose EOS radiography does not significantly differ from conventional radiography for the evaluation of cerebral shunts. In addition, EOS affords a much lower radiation dose and a lower cost.

“…2,3 The unique technical characteristics and functionality of the system allow for significant dose reduction, which is an important consideration in particular for paediatric orthopaedic examinations which may require frequent follow-ups. 4,5,6 The purpose of the work presented in this article is to demonstrate the methodology adopted by our team to perform the technical evaluation and commissioning for clinical use of the EOS System, and to present baseline values that can be applied as performance acceptability criteria.…”

We describe the technical evaluation of the commercially available, clinical, biplanar, low dose, digital X-ray system (EOS System, EOS imaging, France). The unit is used for upright, weight-bearing musculoskeletal pathologies, in particular, in the spine and lower limbs. The evaluation incorporated tests on the X-ray generator performance, radiation/imaging field alignment, dose area product accuracy and image quality. The assessment methodology was based on objective parameters and required equipment readily available for technical evaluation of other radiological equipment. Results demonstrated that the system performs well within acceptable performance criteria with regard to X-ray generator performance, radiation/imaging field alignment and dose area product accuracy. In addition, results from the image-quality assessment were aligned with previously published work. The work presented in this article can be used for the technical evaluation of the EOS System at other clinical sites.
