  "description" : "Purpose. - To assess the benefits of using cardiac gated images for treatment planning of breast and internal mammary nodes. Patients and methods. - Inspiration breath hold computed tomography (CT) series acquired at prospectively gated diastolic phase were used for planning. Three different techniques were compared. Technique A used tangents and an internal mammary nodes field covering the three first inter-rib spaces; technique B used an extended internal mammary nodes including part of the medial breast in junction with tangential fields; the 3. technique used helical tomo-therapy. For each technique, two treatment plans were performed: one plan (plan-01) where mean dose and V25 to the heart were considered for plan evaluation and a second plan (plan-02) where the irradiation of the left anterior descending artery was minimized. Results. - V{sub 25} to the heart was found to be less than 5% for all six plans. Mean doses to the heart were within 4.8 to 7.2 Gy. By attempting to lower the dose to the left anterior descending artery, heart D{sub mean} was decreased by 20-30% for the two techniques A and B while being unchanged for tomo-therapy. Regarding target coverage, there was no marked difference between plans where only heart dose was considered (plans-01) and plans where the left anterior descending artery dose was minimized (plans-02). When the left anterior descending artery dose was part of plan evaluation, D{sub mean} to the left anterior descending artery could be decreased by 24, 19 and 9% for techniques A, B and tomo-therapy respectively. The three techniques exposed segments of the left coronary to different levels of dose. Conclusion. - This study showed that evaluation of the dose to the left anterior descending artery coronary may change the treatment strategy. Cardiac gated images without IV contrast permitted a good visualization of the coronaries in order to optimize the dose on these structures. In addition to heart V{sub 25}, the dose to the coronaries should be included in prospective studies on radiotherapy related heart toxicity in association with all additional risk factors.
