Scoliosis is defined as a lateral curvature of the spine, and the full spine radiographyremains the reference standard for diagnosis. In the last few years there has been a growing interest about to radiation doses and associated cancer risk for scoliotic patients undergoing repetitive full spine radiography during their diagnosis and follow up periods.[1] Current guidelines to orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth, has demonstrated that a lateral view at start is essential to have an overview of the sagittal profile, moreover...

The determination of breast dose and cancer risk at any age of exposure, are significant information about radiation safety in repetitive full spine radiography.A phantom study was performed to assess the impact of technical parameters and to evaluate the optimal of subjective image quality. Full-spine radiographs of a humanoid Alderson Rando® phantom were acquired with a Philips DigitalDiagnost 2.1 system. We started by investigating the standard protocol anterior-posterior view (AP) using the technique by automatic exposure control (AEC), the firstly experiment was performed with and...

The firstly experiment was performed, in AP full spine projections, without protection of the gonads, the DAP was 76.72 µGym2 with a (HT) to the breast 0.281 mSv.The results show that AP projection by AEC for full spine x-ray exposure with protection of the gonads, the DAP was 107.52 µGym2 with an (HT) to the breast of 0.286 mSv, both the DAP and (HT) values were significantly higher that low-dose PA. For low dose PA projection with cover gonads, the DAP was 46.9 µGym2 with...

This experiment demonstrates that there is evident relationship between PA projection and breast dose. Equivalent dose (HT) to the breast can be reduced by 93% by performing PA full spine protocol acquisition having the lowest dose without loss of image quality. In conclusion, it is evident that, this study has shown that the use of the PA projection with gonad covers and manual setting of exhibition parameters, allows to reduce radiation dose to the breast, while allowing a good diagnostic image. Use of lead cover,...
