Scoliosis is defined as a lateral curvature of the spine, and the full spine radiography remains 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 in the literature several theories have been proposed to explain reducing exposure by only using postero-anterior projection during follow up.

It is recommended that frontal radiographic studies are made postero-anteriorly, using low-dose radiographs, including visualization of the femoral heads and protection of the gonads. [2-5]

Much research has documented that breast is one of the most radiation-sensitive organs to stochastic effects, moreover a higher incidence of breast cancer in female scoliosis patients following childhood radiation exposure has been observed.

In other words, female have higher cancer induction probability than male if both genders have undergone the same full spine radiography monitoring protocol. This may be due to the incidence of breast cancer in female when compared to negligible incidence of breast cancer in male.

Based on the results of this studies, the use of projection postero - anterior that incur a breast lower radiation dose in full spine x-ray imaging is advocated. Nonetheless, in clinical practice often is used antero – posterior view because this position is likely to provide a more comfortable patient position in which to undertake a radiographic image.

Despite the growing high-quality evidence, the heterogeneity of the study protocols limits generalizability of the recommendations, in this specific area is no evidence of strength level I, very few of level II.

There is a general agreement to avoid inappropriate use of X-rays in children to reduce the exposure. Although the effective doses (ED) is the major factor to consider, we calculated the breast equivalent dose during full spine radiography. The paper aims to optimize our standard full spine radiography compared to diagnostic quality [6] and reduction equivalent dose (H_T) to the breast.
