摘　　要：探讨乳腺X线摄影常规体位下肿物投影位置与体表定位的关系,有利于影像诊断医师对病灶位置的准确描述。方法 随机抽取临床可触及乳腺肿物的患者405例,行乳腺X线摄影,肿物的体表位置与投影位置一致为符合,计算符合率,并采用χ2 检验进行统计学分析,比较下垂型乳房与非下垂型乳房2组符合率差异是否存在统计学意义。结果 405例患者中常规体位投影位置与体表定位的符合率为65.93%,其中103例非下垂型乳腺的符合率为68.93%,302例下垂型乳腺的符合率为64.9%,2组符合率差异无统计学意义（χ2=0.556,P=0.456）;位于内上象限,内下象限,外上象限,外下象限,乳腺外侧,乳腺内侧,乳头上方,乳头下方的肿物与投影位置的符合率分别为45.57%,95%,88.1%,63.64%,36.84%,13.33%,43.9%,53.85%,位于不同象限和方向的肿物与投影位置的符合率有显著差异。结论 乳腺病灶位置描述的准确性与乳腺是否下垂无关,与病灶所占象限或方向有关。内下及外上象限的乳腺疾病符合率较高,可利用常规体位描述肿物的位置,但对肿物进行精确定位还需要加照辅助位。Objective To investigate the relationship between tumor projection position and body surface positioning in conventional position mammography. Methods The mammography data of 405 patients with clinical palpable breast tumors were collected. The tumor＇s surface position and projection position with consistent, and then the coincidence rate was calculated and statistical anal- ysis was performed by chi-square test. The coincidence rate between the pendulous type breast and non-pendulous type breast were statistical analysed. Results In 405 patients, the coincidence rate between normal position projection position and surface positioning was 65.93%. Among 103 cases of non-pendulous breast the coincidence rate was 68.93%, and 302 cases of pendulous breast the coincidence rate was 64.9%. There was no significant difference between the two types （X2 =0. 556,P=0. 456）. The tumor located at upper inner quadrant, lower inner quadrant, upper outer quadrant, lower outer quadrant, breast lateral, breast medial, above the papilla, beneath the nipple location of the projection consistent rate was 45.57%, 95%, 88. 1%, 63.64%, 36.84%, 13. 33%, 43.9%, 53.85%, respectively. Located in different quadrant and direction of the neoplasm and projection position of coincidence rate have significant difference. Conclusion The accuracy of breast lesions position description and mammary gland is sag have noth- ing to do with pathological changes of the quadrant or direction. The lower inner quadrant and upper outer quadrant of breast tumors with high projection position, by using the conventional position can be described tumor position.
