中文摘要 | 女性常因乳腺發育不良、產後乳腺萎縮及乳癌切除乳房等原因進行乳房整形手術。在執行乳房X光攝影的條件無法完全使用自動偵測劑量模式(Automatic exposure control, AEC),需使用手動劑量模式,且只能針對剩餘乳腺做影像判讀。本實驗第一階段藉由180 cc和250 cc容量的矽膠植入物分別用數片10 mm和20 mm厚度壓克力假體堆疊模擬不同的乳房厚度;皆用ACR RMI156假體模擬剩餘乳腺,依據儀器的操作手冊中手動劑量表及臨床放射師依臨床需求經驗修改後的手動劑量表調整kV、mAs等方式進行數位乳房X光攝影。第二階段影像由兩位放射科專科醫師進行主觀評分;客觀評分方式為圈選ROI方式計算CNR值。結果顯示:主觀評分方面,當50 mm厚度時,調整版與原廠1版(p =0.016)有顯著差異,其餘皆無顯著差異。客觀評分方面,當40 mm厚度時,調整版的影像品質最高,且腫塊與背景的對比最高。50-70 mm厚度,原廠版1的對比度最高,其次為調整版,原廠版2最小;80-100 mm厚度,調整版的對比度比原廠版2高。 |
英文摘要 | It caused the female to execute mammo plastic surgery by glandular vestigial, postnatal glandular atrophy, to cut out the breast and so on. To operate mammography which need manual totally to adjust the dosage, it can't use by automatic exposure control, AEC. The first period use by 180 c.c. and 250 cc silicon with 10 mm and 20 mm Polymethylmethacrylates (PMMAs), simulate different breast thickness they also simulate remainder glandular by ACR RMI-156 phantom. According to the manual mode, manual mode and radiographers use clinical experience to modify manual mode's kV, mAs ways to execute digital mammography. The second period is to subjective score by two radiologists. The objective score is which circle the ROI to count the CNR value. In subjective scoring, the results display that significant differences was found between adjustment version and original version 1 at 50 mm thickness (p=0.016), but the 40 mm and 60-100 mm show no significant difference. As for the objective score in the 40 mm thickness, the images is the highest quality, also the mass and background which the contrast are highest, too. In 50-70 mm thickness, the highest contrast is original version 1 higher than adjustment version, the lowest is original version 2. 80-100 mm thickness, the contrast in adjustment version is higher than original version 2. |
