The purpose of this study is to investigate the cause analysis according to the difference between the pre exposure tube voltage and actual exposure tube voltage in mammography in connection with breast pressure thickness, breast size and body mass index and to find the improvement. The study tracked 377 women age 40 and older among the mammography examiners conducted by the National Health Insurance Corporation. It was analyzed that breast pressure thickness, breast size and body mass index according to the difference between the pre exposure tube voltage and actual exposure tube voltage among the parameters of dose report been sent to the picture archiving communication system with reference to the image with cranio-caudal projection in mammography. As are result, it shows that the thicker the breast thickness, smaller the breast size and lower body mass index, the higher the difference of tube voltage. In conclusion, the minimum tube voltage of mammography machine should be reset in order to set the tube voltage according to breast pressure thickness and breast size that are suitable for our country in mammography, in addition, it was considered that radiologist should make an effort to reduce radiation exposure and make a good quality image with reducing the difference of mammography condition by making a correct exposure condition in case of examining the patients with thin breast pressure and small breast size.

The breast cancer occurrence have been increase yearly. Consequently the effort for early discovery or prevention is necessary. The study investigated the age distribution rate and a disease distribution occurrence rate in the breast medical examination of Ulsan city area. Breast medical examination distribution ratio it preferred the breast ultrasound with mamography 38.8% breast-ultrasonogrphy 61.2% to be investigated. The disease categories distribution was various from breast-ultrasound medical examination and it was investigated with becomes ramification. The reading find was many most infiltrating duct carcinoma from 40 age stage. The ductal carcinoma in situ was many from 50 age stage. The most many disease was investigated HP(Heterogenous dense nodule or mass parenchyma pattern) with 29.2%. Also the breast abscess or mastitis disease is confirmed only the breast-ultrasonography examination, even from the outside disease it was investigated with the fact that the breast-ultrasound raises the discrimination.

The purpose of this study was to measure breast discomfort, breast pumping time, and breast milk compositions, specially lipid, calorie, and creamatocrit, after Oketani breast massage program. This study is a single group pretest-posttest design. Seventeen mothers who have preterm babies were received Oketani breast massage program. To evaluate the effects of Oketani massage program, data were measured the breast discomfort by the visual analogue scale, breast pumping time, and breast milk lipid, calorie, creamatocrit by a Creamatocrit plus machine, the standard centrifuge with digital calipers. The breast discomfort was significantly reduced after two Oketani breast massage programs(p<.05). In terms of composition of breast milk, lipid, calorie, and crematocrit were significantly increased after second Oketani massage program(p<.05). The Oketani breast massage program applied to mothers who have preterm babies could reduce breast discomfort and increase lipid, calorie, and creamatocrit of breast milk.

Mammography has the advantage of being economical, simple and effective in detecting microcalcification, but breast is a highly sensitive organ and is accompanied by the risk of an over-exposure. While accurate dose assessments are important to prevent this, current breast dose assessments are limited to breast implant patients. This purpose of this study was to identify dose variations due to tube voltages by forming a mock-up with breast implants for an accurate dosimetric assessment on breast implant patients. As a result, doses from the presence of breast implants were smaller than those from the absence of the mammal. As the result of the change of the voltage to 26, 28, 30, and 32 kV, the imcreased tube voltage included larger dose regardless of the presence of Breast implant. Therefore, it is believed that diagnosis recommendations for breast implants will be possible if further studies on internal and external bioretical imaging and quality assessment are carried out as the basis for this study.

Breast MRI is the most accurate adjunctive to the mammography for the screening of breast cancer. Despite lack of randomized controlled trials on the effectiveness of MRI screening, it is now recommended for the women at high risk for breast cancer by the American Cancer Society and the National Comprehensive Cancer Network based on several prospective observational studies. In Korea, a retrospective study reported that preoperative MRI screening of the contralateral breast in women with unilateral breast cancer was associated with reduced metachronous cancer incidence. To introduce breast MRI as a supplemental modality to screening mammography in Korea, standardization and education of interpretation, establishment of MR-guided biopsy and adequate indication, and evaluation of cost-effectiveness and should be preceded.

Purpose: Tc-99m MIBI scintimammography has been validated as an useful non-invasive diagnostic tool for the primary breast cancer. But most studies have included small population of patients. We have experienced a large study population and investigated the diagnostic usefulness of Tc-99m MIBI scintimammography in detection of primary breast cancer and axillary lymph node metastasis. Materials and Methods: This study included 305 patients who underwent scintimammogtaphy for palpable breast masses or abnormal radiologic findings. Tc-99m MIBI scintimammography was performed 10 minutes after intravenous injection of 925 MBq of Tc-99m MIBI. If the early image revealed abnormal finding, 3 hour delayed image was also acquired. We calculated early and delayed lesion to non-lesion ratios (L/N). The pathologic diagnosis was obtained from surgical operation or FNAB and compared with the results of Tc-99m MIBI scintimammography. Results: Malignant breast diseases were 155 and benign ones were 150. Tc-99m MIBI scintimammography revealed 132 true positive, 23 false negative, 10 false positive, and 140 true negative cases. The sensitivity, specificity, positive predictive value and negative predictive value for the primary breast cancer detection were 85.2%, 93.4%, 92.9%, and 85.9%, respectively. The sensitivity, specificity, positive predictive and negative predictive values of Tc-99m MIBI scintimammography in detecting metastatic axillary lymph node involvement were 22%, 90.4%, 61.9% and 62.3%, respectively. Early L/N of malignant breast disease was significantly higher than that of benign one ($2.44{\pm}0.97\;vs\;1.94{\pm}0.78$, p=0.01). Delayed L/N had no significant difference between malignant and benign breast diseases ($1.94{\pm}0.52\;vs\;1.91{\pm}0.73$, p=0.43). Conclusion: Our study revealed that Tc-99m MIBI scintimammography was an useful diagnostic tool for the diagnosis of breast cancer. And early L/N ratio might provide complementary role in the detection of breast cancer. But the Tc-99m MIBI scintimammography had limited value in the detection of small breast cancer (less than 1 cm) and axillary lymph node metastasis.

감시는 유방건강자료의 알맞은 경영에 대한 기본적인 판단이다. 감시는 꼭 필요한 노력과 근원에 초점을 맞추는 것과 똑같이 엄청난(확실한) 문제점 지역에서 할 수 있다. 감시는 농장에서 장기간 유방건강관리가 필요 하다는 것에 긴장을 가져야 한다. 다른 곳으로 주의가 갈 수 있다는 것에서 많은 영향이 있을 수 있다. 감시는 정확한 행동동기가 있어야 한다. 감시는 유방염관리 권장이 적용되는 것과 같이 유질에서 향상의 직접적이고 시간 코스가 문서로 외기 위한 돌봄이 있어야 한다. 유방건강자료의 알맞은 관리 없이는 유방건강과 유질에 대한 지속적인 최고의 기록은 성취되기 힘들다.

본고에서는 유방건강에 대한 목장 현장에서의 접근방식이 제시되었다. 유방건강에 대한 모니터링은 정기적인 데이터 수집과 분석 및 관리방법의 정기적인 평가로 이루어진다. 최종 목표는 위생, 신체충실도, 유두끝 상태, 치료 등과 같은 유방건강 관리에 있어서의 중점관리점을 항상 최적의 결과가 나올 수 있도록 관리하는 것이다. 유방염은 많은 요인에 의해 발생하는 질병이어서 현실에서는 모든 유방염 문제를 완전히 예방하기가 불가능하다. 그러므로, 유방건강에 대한 데이터는 문제가 임상형으로 되기 이전에 이상을 감지할 목적으로도 모니터링 된다. 유방건강에 대한 데이터와 관리방식을 정량측정함으로써 하나의 목장이 효율성에 대해 높은 관심을 갖고 각 과정에 대해 생각하고 명백한 목표를 가지고 있으며 각 과정과 결과에 대해 평가를 하는 하나의 사업으로서 접근된다. 전체적인 접근은 구체적이고, 측정가능하며, 용인할만하고, 현실적이며, 기한이 정해진 SMART한 목표를 갖는 것으로부터 시작되며, 이러한 목표들을 실현하기 위한 행동계획이 뒤따른다.

스크린-필름 X선 유방조영술(Screen-film X-ray mammography)은 유방암 진단을 위한 기준이 되는 방법으로 독보적인 위치를 차지하고 있다. 그러나 현재 사용되는 스크린-필름 방식 유방조영술은 여러 가지 한계점들이 인식되어 왔으며, 만약 유방 X선 사진(mammogram)이 디지탈 형식으로 곧 바로 얻어진다면 영상의 질(image quality)과 방사선량의 감소 가능성 관점에서 향상될 수 있다는 증거가 있다. 본 논문에서는, 디지탈 유방조영술에 대한 논리적 근거가 제시되고, 스크린 대용으로 개발되고 있는 X-선 검출기들과 이들을 사용한 여러가지 디지탈 유방조영술 시스템들을 분석 전망한다. 디지털 유방조영술을 실용화하기 위해 해결되어야 할 문제점들이 논의된다.
