根據(jù)一項(xiàng)最新研究發(fā)現(xiàn)：一種計(jì)算機(jī)輔助檢查（CAD）系統(tǒng)幫助放射科醫(yī)生能夠更加快速有效地確定核磁共振檢查發(fā)現(xiàn)的腫瘤位置和大小，這將能夠改善患者的治療。

這項(xiàng)研究是在西班牙Clinica Girona進(jìn)行的，對(duì)比了CAD系統(tǒng)與標(biāo)準(zhǔn)MRI乳房成像軟件。36例確診為乳腺癌的患者在該項(xiàng)研究中，接受了使用標(biāo)準(zhǔn)軟件與CAD系統(tǒng)的MRI掃描檢查。

MRI掃描中使用的CAD系統(tǒng)，允許放射科醫(yī)生能夠更加有效地確定腫瘤體積。根據(jù)Joan C. Vilanova醫(yī)生的說(shuō)法：體積大小與在顯微鏡下觀察到的更加接近，他是Clinica Girona核磁共振科主任，該項(xiàng)研究的首席作者。Vilanova醫(yī)生說(shuō)：“在83％的病例中，CAD系統(tǒng)最終[后處理的]的影像質(zhì)量比標(biāo)準(zhǔn)軟件的質(zhì)量要好。”除此之外，放射科醫(yī)生只需要12分鐘來(lái)研究與解釋CAD系統(tǒng)的掃描結(jié)果，而標(biāo)準(zhǔn)MRI軟件影像則需要19分鐘。Vilanova醫(yī)生說(shuō)，一次乳房MRI研究每次檢查獲得超過(guò)1000幀影像。

在10例患者中兩套系統(tǒng)都發(fā)現(xiàn)了額外的腫瘤，其中8例在進(jìn)行MRI檢查之前原計(jì)劃進(jìn)行乳房腫瘤切除術(shù)。然后他們的治療改為乳房切除術(shù)。Vilanova醫(yī)生解釋說(shuō)：“如果沒有進(jìn)行MRI檢查，癌癥組織將會(huì)被留在乳房之中。CAD系統(tǒng)幫助我們和臨床醫(yī)生在評(píng)判乳房MRI結(jié)果的時(shí)候更加自信。實(shí)際上，乳房MRI檢查在過(guò)去的9個(gè)月之中已經(jīng)增加了50％。”

Dr. Vilanova presented the results of the study at the annual meeting of the American Roentgen Ray Society in May 2005 in New Orleans (LA, USA).

CAD Makes Breast MRI More Effective
 
A computer-aided detection (CAD) system is helping radiologists to more rapidly and effectively determine the location and size of tumors discovered on breast magnetic resonance imaging (MRI) data, which could change a patient’s treatment, according to a new study.

The study was performed at Clinica Girona (Spain) and compared the CAD system to breast imaging software that comes standard with MRI units. Thirty-six patients with diagnosed breast cancer in the study underwent an MRI scan using the standard software and the CAD system.

The CAD system used with the MRI scanning allowed radiologists to more effectively determine the size of the tumors. The size correlated more closely to what was seen under the microscope, according to Joan C. Vilanova, M.D., director of the department of magnetic resonance at Clinica Girona and lead author of the study. “The quality of the final [postprocessed] CAD system images was better than the standard software images in 83% of the cases,” said Dr. Vilanova. In addition, it took radiologists an average of 12 minutes to study and interpret the CAD system images compared to 19 minutes for the standard MRI software images. A breast MRI study generates more than 1,000 images per examination, according to Dr. Vilanova.

Both systems found additional tumors in 10 patients, eight of whom were scheduled to under a lumpectomy before the MRI scan was performed. Their treatment was then changed to a mastectomy. “Cancerous lesions would have been left within the breast if breast MRI had not been performed,” Dr. Vilanova said. “The CAD system has allowed us and our clinicians to have more confidence in our ability to evaluate breast MRI. In fact, the number of breast MRI examinations has increased by 50% in the last nine months.”

Dr. Vilanova presented the results of the study at the annual meeting of the American Roentgen Ray Society in May 2005 in New Orleans (LA, USA).
