3-D Technology Saves Lives
3D技術(shù)拯救生命
From VOA Learning English, this is the Health Report.
這里是美國之音慢速英語健康報道。
Three-dimensional technology -- known as three-D -- gives depth to objects that would otherwise appear two-dimensional, or flat. Three-D makes movies and video games look more realistic. And now it could help save lives.
3維技術(shù)又稱3D技術(shù)，這種技術(shù)給物體提供深度，要不然就只有2維，淺平而缺乏深度。3D技術(shù)使得電影和視頻游戲顯得更加真實，而且現(xiàn)在它還有助于拯救生命。
For years, mammograms have played an important role in finding breast cancer. But these X-ray pictures of the human breast often miss dangerous lumps or tumors.
多年來，乳房X線照片對于發(fā)現(xiàn)乳腺癌起到重要作用。但是這些X射線照片經(jīng)常會遺漏掉危險的腫塊或腫瘤。
And they also produce false positives. A false positive wrongly appears to show suspicious tissue. And that causes painful, unnecessary biopsies to examine that tissue.
而且X射線照片也會產(chǎn)生假陽性現(xiàn)象，假陽性會錯誤的顯示可疑的組織，而且會引起疼痛，使病人進(jìn)行不必要的活組織檢查。
A new study shows that three-D technology could change the way doctors look for breast cancer.
最新研究表明3D技術(shù)可以改變醫(yī)生檢查發(fā)現(xiàn)乳腺癌的方法。
When Zulima Palacio discovered she had breast cancer, it already had reached stage three. That means that the cancer was very dangerous.
當(dāng)Zulima Palacio發(fā)現(xiàn)自己得了乳腺癌時，病情已經(jīng)發(fā)展到第三階段。這就意味著這個癌癥很危險了。
"Even a month before it was detected, I went for a sonogram and they told me, 'You're fine, go home.'"
“甚至在一個月以前都沒有檢查出來，我去做聲波圖檢查，檢查完后他們告訴我，‘你很好，回家吧’”。
Ms. Palacio is now cancer free. But the two-dimensional mammogram missed all three of her tumors.
帕拉西奧女士現(xiàn)在是無癌的，但是這標(biāo)準(zhǔn)的2維乳房X線照片卻未檢測出她的三個腫瘤。
Many doctors - including cancer surgeon Negar Golesorkhi - say standard mammography does not find enough cancerous tumors. She says looking for cancer in dense, thick breast tissue is like looking for a polar bear in a snowstorm. In other words, it is very difficult.
包括癌癥外科大夫Negar Golesorkhi在內(nèi)的很多醫(yī)生稱，標(biāo)準(zhǔn)的乳房X線照片不能找出足夠的惡性腫瘤。Negar Golesorkhi說，在厚的乳腺組織中尋找癌癥，就像在暴風(fēng)雪中尋找北極熊。換句話說就是，非常困難。
"When we look for cancer on a mammogram in dense breast tissue, we’re looking for a polar bear in a snow storm, so it would be very difficult to find."
“當(dāng)我們利用乳房X線照片在稠密的乳腺組織中尋找癌癥，就像在暴風(fēng)雪中尋找北極熊，那是非常難找的。”
A few years ago, the U.S. Food and Drug Administration approved the use of three-D mammography. And three-D technology found Jennifer Hoeft's tumor.
幾年前，美國食品和藥物管理局批準(zhǔn)了3D乳房X線照片的使用，3D技術(shù)發(fā)現(xiàn)了Jennifer Hoeft的腫瘤。
“It was a very small tumor. It was only an 8 millimeter tumor that couldn’t be felt.”
“這是一個非常小的腫瘤，一個感覺不到的只有8毫米的腫瘤。”
Sarah Friedewald is a doctor at Lutheran General Hospital in the U.S. state of Illinois. She led a study to compare the results of three-D and two-D mammography from nearly a half million patients.
Sarah Friedewald是美國伊利諾斯州路德綜合醫(yī)院的一名醫(yī)生。她帶頭作了一項研究，在50萬病人中比較3D乳房X線照片和2D乳房X線照片的功效。
Dr. Friedewald says they found more cancers using three-D mammograms versus, or compared to, two-D mammograms. And they found more cancers that kill.
Friedewald稱，他們發(fā)現(xiàn)用3D乳房X線照片相比2D乳房X線照片，可以發(fā)現(xiàn)更多癌癥，而且還發(fā)現(xiàn)很多癌癥是致命的。
“We found invasive cancers or the cancers that we worry about, the ones that could potentially kill people more frequently in women who had the 3-Dmammogram versus the women who just had the 2-D mammogram. At the same time, fewer people had to come back for unnecessary testing which creates unnecessary anxiety.”
“做3D乳房X線照片的婦女查出來的侵入式癌癥或者我們所擔(dān)心的癌癥，相對于那些只做2D乳房X線照片的婦女，更可能會頻繁的使人致命。與此同時，做2D乳房X線照片少數(shù)人還得再去做不必要的檢查，產(chǎn)生不必要的憂慮。”
Dr. Friedewald says tumors that are difficult to see on a standard mammogram are easy to find in 3dimensions.
Dr. Friedewald稱腫瘤很難在乳房X線照片上被發(fā)現(xiàn)，但是在3D乳房X線照片上卻很容易被發(fā)現(xiàn)。
Jennifer Hoeft is grateful that she had three-D mammography.
Jennifer Hoeft很慶幸自己做了3D乳房X線照片。
“I truly, truly believe that the 3-D mammography is what caught my cancer early and is allowing me to pretty much live my life the way I want to.”
“我真的堅信3D乳房X線照片很早就發(fā)現(xiàn)了我的癌癥，這項技術(shù)幾乎可以讓我按自己喜歡的方式生活。”
Dr. Friedewald told VOA that she expects three-D to replace the usual two-D mammograms in time. Her study was published in the Journal of the American Medical Association.
Friedewald告訴美國之音記者，她期待3D乳房X線照片可以很快取代通常的2D乳房X線照片。她的這項研究被發(fā)表在《美國醫(yī)學(xué)會》雜志上。

A woman undergoes a mammography exam, a special type of X-ray of the breasts used to detect tumors. |
