For irradiation of the parasternal lymph nodes by high-energy electrons the target volume depth, i.e. the depth of the parasternal nodes below the skin surface, was determined by CT in 25 consecutive female patients with a sternal irradiation field. On measurement at the cranial end of the sternum, at a middle level, and at the caudal part of the sternal field, intraindividual differences were low, whereas interindividual findings differed markedly--depending on thickness of subcutaneous fatty tissue. For individual treatment planning, we recommend measuring target volume depth by CT.
对于采用高能电子束照射胸骨旁淋巴结，在25例连续的有胸骨照射野的女性患者中，通过CT确定靶区深度，即胸骨旁淋巴结在皮肤表面以下的深度。在胸骨上端、中间水平及胸骨野下端测量时，个体差异较小，而个体间的测量结果差异显著，这取决于皮下脂肪组织的厚度。对于个体化治疗计划，我们建议通过CT测量靶区深度。
