比较Eklund摄影方法与传统X线摄影对假体隆胸术后影像评估的价值

摘要

Objebtive To compare the application value between Eklund and conventional mammography techniques in patients with augmented breasts. Methods A total of 16 female patients (age 38-55, median 44 years) with breast augmentation underwent mammography using conventional and Eklund technques (CC and MLO position). Thirty two images were obtained in each position as well as compression strength (daN) and breast thickness (mm). The distance(mm) between nipple and implant were measured at the workstation (Advantage Windows 4.4). The grade of anatomical structure and details were evaluated by two experienced radiologists blinded to any patients’ information. Graphpad prism 5.01 was used to calculate the differences in these parameters between the conventional and Eklund techniques. A t-test was used for the comparisons of compression strength, breast thickness, and distance between nipple and implant. Wilcoxon test was used for the comparisons of grade of anatomical structure and details. Results The compression strength, breast thickness, and distance between nipple and implant of conventional CC position were 6.813±1.857 daN, 52.188±14.104 mm, and 30.115± 16.814 mm, respectively, grade 3 of anatomical structure and details account for 25.00%;6.969±2.132 daN, 58.031±10.237 mm, and 23.342 ±10.190 mm, respectively, grade 3 of anatomical structure and details account for 90.63%in conventionalMLO position;6.688 ±1.891 daN, 24.094 ±9.484 mm, and 38.189 ±11.925 mm, grade 3 of anatomical structure and details account for 6.25% in Eklund CC position; 7.094 ±2.205 daN, 24.906 ±11.223 mm, and 39.686 ±11.664 mm, respectively, grade 3 of anatomical structure and details account for 87.50% in Eklund MLO position. The statistical differences were found between conventional and Eklund techniques except for compression strength. Conclusion Eklund technique is of great value for the evaluation of augmented breast.%目的：比较Eklund摄影方法与传统X线摄影方法对假体隆胸术后病人的影像评估的价值。方法对16例假体隆胸术后的女性病人（38~55岁，中位年龄44岁）行乳腺X线摄影，采用常规摄影方法及Eklund摄影方法，获得常规摄影方法头尾位、内外斜位、Eklund摄影方法头尾位、内外斜位各32幅影像，并获得相应的压迫力度（daN）及压迫后乳腺厚度（mm）。通过Advantage Windows 4．4工作站测量乳头到假体的最短距离（mm）。由2名放射科医生采用盲法读片对乳腺显示的解剖结构和细节进行评分。采用Graphpad prism 5．01统计分析软件对传统摄影方法、Eklund摄影方法的压迫力度、压迫后乳腺厚度、乳头到假体距离进行t检验，对传统摄影方法、Eklund摄影方法的解剖结构和细节进行Wilcoxon检验。结果常规摄影方法头尾位压迫力度、压迫后乳腺厚度、乳头到假体的最短距离分别为（6．813±1．857） daN、（52．188±14．104） mm、（30．115±16．814） mm，解剖结构和细节评分3分病人约占总数25．00％；常规摄影方法内外斜位为（6．969±2．132） daN、（58．031±10．237） mm、（23．342±10．190） mm，解剖结构和细节评分3分病人约占总数90．63％；Eklund摄影方法头尾位为（6．688±1．891） daN、（24．094±9．484） mm、（38．189±11．925） mm，解剖结构和细节评分3分病人约占总数6．25％；Eklund摄影方法内外斜位为（7．094±2．205） daN、（24．906±11．223） mm、（39．686±11．664） mm，解剖结构和细节评分3分病人约占总数87．50％。两组之间除了压迫力度其余参数差异均有统计学意义。结论 Eklund摄影方法对于假体隆胸术后病人的影像评估具有重要价值。
