  • Conclusions below are drawn after survey date from 1,969 samplers of mammography and 1,531 breast ultrasound for 10 months, from 1 July 2006 to 30 April 2007. 1. Ages between 40 and 50 of samplers take the largest part of age distribution, and 68.57% of mammography and 71.32% of samplers are fallen under the category. 2. Samplers judged by diseased patients are 31.95% samplers of mammography and 45.79% samplers of breast ultrasound. 3. Age distributions of diseased patients were from 30 to 60 in mammography, 30 to 50 in breast ultrasound. 4. Breast ultrasound shows little difference between left side and right side of diseased part, but mammography shows significant diseased part in both sides. 5. As a result of reading examination, there is higher probability of detection in order of Calcification, Nodular, Mass in mammography. And Cyst, Nodular, Mass in breast ultrasound. 6. As a reading examinations, probability of judging a certain disease in high in mammography, but breast ultrasound shows 1 or 2 kinds of disease.

  • More than 4 million women undergo breast cancer (BC) screening with mammography each year in Korea. Digital mammography (DM) was introduced in 2000, and it has been reported to have a higher diagnostic accuracy than screen-film mammography (SFM) or computed radiography (CR) in women with dense breasts. According to a study using data from the National Cancer Screening Program for BC, the diagnostic accuracy of DM was higher than those of SFM and CR, regardless of age, breast density, and screening round. Currently, despite high supply rate among OECD countries, the distribution of DM equipment is approximately 35% in Korea. For quick replacement with DM, it will be necessary to improve its fee for the National Health Insurance and support an educational program for radiologists. In addition, efforts should be made to increase the accessibility of DM.

  • Purpose: To compare the treatment outcomes and to analyze prognostic factors between the use of a breast-conserving treatment(BCT) and a mastectomy for early stage breast cancer. Materials and Methods: We retrospectively reviewed 1,200 patients with pathological stage T1-2N0 breast cancer who received surgery between September 1994 and December 2002 at Samsung Medical Center. We compared the patient characteristics and treatment outcomes between the two treatment groups. Results: Among the 1,174 eligible patients, 601(51.2%) patients received a BCT and the remaining 573(48.8%) patients received a mastectomy. The mastectomy group of patients had significantly more cases with a larger tumor size, multicentricity, extensive intraductal component, and estrogen- and progester-one-receptor negativity. The ten-year overall survival rates(OS) of the BCT and mastectomy groups were 91.96% and 91.01%, respectively(p=0.1274). The ten-year disease-free survival rates(DFS) were 80.48% for the BCT group of patients and 84.95% for the mastectomy group of patients, respectively(p=0.8795). Conclusion: Our study shows some differences in patient characteristics between the two treatment groups. However, these differences did not result in significant survival differences.

  • The purpose of this study is to evaluate the diagnostic accuracy of breast cancer from mammography images and to investigate the characteristics of patients who was diagnosed as a breast cancer. The subjects for this study were 85 patients who underwent breast imaging test with screen-film method and investigated from March 2010 to October 2010. The average age of the subjects is 51.9 years old. The 43.5% of onsets were located at the upper outer quadrant (UOQ). In terms of the age group, group for 40-49 ages were highest 37.6 (32/85)%. As for breast composition, fatty and dense breast were 30.6% (26/85) and 69.4% (59/85) respectively. The average age of the patients with fatty breast is 62.4 years old, whereas those with dense breast was 46.5 years old. The false negative rate of mammography images was 27.1% (23/85) and the sensitivity of mammography was 72.9% (62/85). The false negative rate of the patients with dense breast was 32.2% (19/59). the sensitivity of them was 67.8% (40/59).

  • 핵의학적 유방영상법은 오랜동안 시범되어 왔지만 임상에서 큰 역할을 못했고, 근래에 핵의약품과 핵의학기기 사용방법의 발전으로 scintimammogram(SM)이 다시 각광을 받게 되었다. 유방암 진단에 대한 핵의학영상법의 특이도와 예민도가 방사선 유방촬영법보다 높다고 보고되었으나 1cm보다 작은 유방암은 SM에 용이하게 발견되지 않는다. 본 보고에서는 1cm보다 작은 유방암이 발견된 두 증례를 발표한다. 한증례는 $^{99m}Tc$ MDP를 수술전 골영상을 위해서 사용하였고, 두 번째 증례는 비촉지 유방종괴를 $^{99m}Tc$ MIBI로 유방촬영 하였다.

  • Breast MRI is a cutting-edge technology in the diagnosis and intervention of breast abnormalities. Over the last decade, breast MRI has evolved from a research field to a clinical field. Radiologists should understand the indications, how to obtain adequate images, and how to interpret and report their findings. Breast MRI is now used in the differentiation of benign from malignant mass, preoperative staging of breast cancer patients, assessment of tumor response to neoadjuvant chemotherapy, and evaluation of women with breast implants. It can also be used as a supplemental screening modality for high-risk women. Qualified radiologists and adequate MRI technique are crucial for the success of these purposes. This review is focused on the indication, standardized use of lexicon and categorization of breast MRI.

  • Mammography equipment is an essential detector for making an early diagnosis of female's breast lesion. Recently, in most hospitals, a digital mammography detector is used due to the wide and consistent supply of digital mammography equipment. However, the average effective radiation is increasing due to the indiscreet use of CR or DR mammography. The purpose of this study is to recognize the possible indirect radiation damage, which can be occurred due to an excessive effective exposure of radiation, by evaluating spacial radiation rate of the digital mammography detector used for female patient. Consequently, the high mount of spacial radiation showed digital mammography equipment on the horizontal direction. Considering the result, digital mammography equipment should be installed by avoiding along the horizontal direction.

  • 최근 몇년간 국립수의과학검역원에서 조사한 바에 따르면, 국내 젖소에서 유방염을 일으키는 주된 원인균은 황색포도상구균을 제외하고는 거의 대부분 젖소의 환경으로부터 유래하는 환경성 세균에 의한 것으로 확인된 바 있다. 국내 젖소의 유방염 원인균으로 작용하고 있는 이러한 환경성 세균 중 coagulase-음성 포도상구균 (Coagulase-negative Staphylococci, CNS)과 E. coli 등의 그람 음성균이 가장 많은 비율을 차지하였지만 그 외에 Streptococcus uberis를 비롯한 환경성 연쇄상 구균과 장구균도 상당한 비율을 차지하는 것으로 조사되었으며 이에 대해서는 지난 9월호에서도 상세히 기술한 바 있다. 환경성 연쇄상구균과 장구균은 젖소에서 유선감염 및 임상형 유방염의 중요한 원인이며 환경성 연쇄상구균 중 가장 흔히 발견되는 유방염 원인체는 Streptococcus uberis 로서, 이는 국내에서뿐만 아니라 미국, 유럽, 뉴질랜드, 호주 등에서 수행된 많은 연구결과에서도 마찬가지로 나타났다. 장구균 중 가장 흔히 분리되는 균종은 E. faecium과 E. faecalis로서 검역원에서 지난 몇 년간 조사된 결과에서도 이 두 가지 균 종이 유방염우유에서 분리된 장구균의 90% 이상을 차지하였다. 이러한 환경성 연쇄상구균과 장구균은 사람과 동물의 장관, 분변, 감염된 유방 및 전체적인 목장 환경에서 분리되고 있다. 장구균은 일반적으로 환경성 연쇄상구균/장구균 유방염 감염증 중의 일부일뿐이고 장구균에 의한 유방염이 목장의 주된 문제가 되는 일은 비교적 드물다. 현재, 장구균에 의해 발생하는 유방염은 S. uberis를 통제하기 위해 사용되는 방법과 동일한 방법으로 통제할 수 있다고 여겨진다. 원인체에 상관없이 유방염을 통제하기 위한 기본적인 원칙은 유방염을 일으킬 수 있는 병원체에 유두끝이 노출되는 기회를 줄이거나 감염에 대한 젖소의 저항성을 증가시키는 두 가지 방법이다. 역으로 얘기하면, 병원체에 대한 유두끝 노출을 증가시키거나 감염에 대한 젖소의 저항성을 감소시키는 요인들은 우군 내에서 더 많은 유방염을 발생시킬 가능성이 높기 때문에 위험요인으로 간주된다. 본 고에서는 환경성 연쇄상구균에 의한 유방염과 관련이 있는 것으로 알려진 이러한 여러 가지 위험요인들에 대해 알아보고 그러한 위험요인을 줄일 수 있는 방법에 대해서도 고찰하고자 한다.

  • This study is a retrospective analysis of the results of tests at three general hospitals in Busan that perform mammography using digital mammography devices. There were 5,320 people in the study, and the results of their breast cancer screening were analyzed to verify the efficacy of breast cancer screening for digital mammography. The average age of patients who performed breast cancer screening was 57.7 years (range 30 to 87 years), and the cancer detection rate was 26, with 4.6 cases per 1,000 people. According to the cancer detection rate by risk factor in patients who conducted breast cancer screening, breast cancer was found in patients without underlying diseases more than in patients with underlying diseases. Additional ultrasound examinations show that the gastronomic rate identified is 3.6%, which is relatively very low compared to that of the Film-Screen system.
