Cumulative Radiation Exposure With EOS Imaging Compared With Standard Spine Radiographs

Abstract

The standard EOS imaging system moderately reduced the total radiation exposure to skeletally immature scoliosis patients. Over the entire treatment course, this represented 2.72 mSv mean reduction or 0.91 years of background radiation. Posteroanterior films significantly reduced breast and thyroid dose.

EOS Micro-dose Protocol: First Full-spine Radiation Dose Measurements in Anthropomorphic Phantoms and Comparisons with EOS Standard-dose and Conventional Digital Radiology

“…For the adolescent phantom we observed an effective dose reduction with EOS standard dose compared with CR, which is consistent with previous reports 10,11 . Our EOS standard-dose results for both phantoms are consistent with most reports [10][11][12] . Table 3 Organ doses to most organs were lower in PAL than in APL.…”

“…with regards to skin entrance dose 7,9,11 ; however, only a few studies have evaluated organ dose and full-body absorbed dose (effective dose) [10][11][12] .…”

How Does Patient Radiation Exposure Compare With Low-dose O-arm Versus Fluoroscopy for Pedicle Screw Placement in Idiopathic Scoliosis?

“…The radiation exposure associated with these hardcopy radiographs approaches the radiation dose of a low-dose O-arm scan. 33 Because of wide practice variability, these radiographs were not considered for our effective dose analysis. Minimizing the use of intraoperative radiographs, particularly the LAT view, may be another effective strategy to lower overall patient radiation exposure.…”

Radiation dose of digital radiography (DR) versus micro-dose x-ray (EOS) on patients with adolescent idiopathic scoliosis: 2016 SOSORT- IRSSD “John Sevastic Award” Winner in Imaging Research

“…Moreover, the digital technique reduces the number of x-ray retake from 5.5% for conventional to 1.0%, which significantly avoids repeated exposure [9]. Literatures also suggest that the change of image orientation from anterior-posterior (AP) view to posterior-anterior (PA) view could greatly reduce the organ dose by approximately three- to eight-fold to the breasts and thyroid because of the lower sensitive organ dose to the anterior structures; thereby, it is suggested for routine spine examinations [10, 11]. Other technical improvement has been made to reduce the exposure including the use of 3-phase x-ray machines and high-speed x-ray films [12].…”
