數位與3D斷層乳房攝影疼痛度的比較

Comparison of Pain Levels Between Digital Mammography and 3D Tomographic Mammography

本研究的目的為3D乳房斷層掃描儀可減輕壓迫疼痛程度，而壓迫疼痛程度是大多數受檢者卻步的關鍵原因，因此本研究設計問卷，欲了解數位乳房攝影儀器與3D乳房斷層掃描儀壓迫疼痛感之比較。本次研究資料收集方式以自擬問卷為工具，以不記名方式收集有關本次3D乳房斷層掃描儀之疼痛分數，如過去有曾接受數位乳房攝影儀器的經驗，則同時填答過去數位乳房攝影之疼痛分數進行比較分析。本研究結果顯示，數位乳房攝影疼痛指數為6.2±2.5分，3D乳房斷層掃描儀疼痛感為2.7±1.4分，有統計上的顯著意義（t = 9.650, P < 0.001）。本研究也依照年齡將資料進行統計分析，有統計上之顯著意義，P值分別為<0.001，<0.001及0.039。結果發現在各年齡中，3D乳房斷層掃描疼痛感均顯著低於數位乳房攝影之疼痛感，3D乳房斷層掃描疼痛感顯著較低。

3D breast tomosynthesis decreases the degree of compression pain and the degree of compression pain makes most subjects reluctant to seek treatment. This study designs a questionnaire to compare the pain that is caused by digital mammography equipment and a 3D breast tomosynthesis. Data collection uses a questionnaire to anonymously collect the pain scores for a 3D breast tomosynthesis scanner. Pain scores are compared with the reported results and the breast density.
The results of this study show that the pain index for digital mammography is 6.2±2.5 points and the pain index for a 3D breast tomosynthesis scanner is 2.7±1.4 points. The results are statistically significant (t = 9.650, P < 0.001). A comparison of the results shows that 3D breast tomosynthesis involves less pain for patients with denser breasts.
A new compression plate for a 3D breast tomosynthesis scanner and more precise calculation using imaging software reduces the degree of breast compression, compared with the force for digital mammography equipment, and reduces compression for patients with dense breasts to encourage the use of mammography.
