유방의 비정형 관상증식증: 탄성초음파검사를 이용하여 악성으로의 등급상향을 예측할 수 있는가?

안영이,김성헌,강봉주,이아원,송병주 대한영상의학회 2011 대한영상의학회지 Vol.64 No.4

Purpose: To evaluate whether the sonoelastographic features of atypical ductal hyperplasia (ADH) can be used to predict an upgrade to malignancy. Materials and Methods: Conventional US and sonoelastographic images were available in 17 women with 18 ADH lesions diagnosed by sonographically guided core needle biopsy. Conventional US findings were analyzed according to the Breast Imaging Reporting and Data System classification. Elastographic images were classified into 5 elasticity scores according to the ITOH classification. In addition, the strain ratio between the mass and surrounding fat tissue as well as the mammographic features were reviewed. All lesions underwent subsequent surgical excision and a correlation was found for sonoelastographic and conventional US findings with pathologic results. Results: Of the 18 ADH lesions that underwent surgical excision, four were found to be malignant (underestimation rate of 22.2%). Moreover, there was no significant difference in elasticity score (p=0.054) and strain ratio (p=0.375) between atypical ductal hyperplasia and lesions upgraded to malignancy on elastography. A mass with microcalcifications on mammography had a significantly higher association with malignancy and microcalcifications, as opposed to the absence of a mass, which was in all cases, benign (p=0.036). Conclusion: Sonoelastography may not be a helpful indicator for the differentiation of atypical ductal hyperplasia from malignant lesions. However, a correlation with mammographic features provides insight for predicting malignancy. 목적: 탄성초음파 영상을 사용하여 비정형 관상증식증의 악성종양으로의 등급상향의 위험도를 예측할 수 있는지 알아보고자 하였다. 대상과 방법: 고식적 초음파와 탄성초음파를 모두 시행하였으며 추후 수술적 제거를 한 총 17명의 환자, 18예를 대상으로 고식적 초음파와 탄성초음파 소견을 후향적으로 분석하였다. 고식적 초음파 소견은 BI-RADS 범주에 따라 분석하였으며, 탄성초음파에서는 Itoh의 분류에 따른 탄성점수와 변형률을 분석하였다. 이중 유방촬영술을 시행하였던 16예의 유방촬영술 소견을 후향적으로 분석하였다. 결과: 수술적 절제를 통해 총 4예에서 악성으로 등급상향 되었으며, 저평가율은 22.2%였다. 악성으로 등급상향 된 군과 그렇지 않은 군 간의 초음파 BI-RADS 범주와 탄성초음파에서의 탄성점수(p=0.054)와 변형률(p=0.375)은 통계학적으로 유의한 차이는 없었다. 유방촬영술에서 종괴와 미세석회화가 함께 있는 경우 악성으로 등급상향 되었으며, 미세석회화만 있는 경우는 양성이었고 모두 통계적으로 의의가 있었다(p=0.036). 결론: 탄성초음파 자체로는 비정형 관상증식증의 악성으로의 등급상향 위험도를 예측할 수 없지만, 유방촬영술 결과를 함께 해석한다면 도움이 될 수 있다.

Response Evaluation to Neoadjuvant Chemotherapy in Advanced Breast Cancer: Comparison of MRI and Positron Emission Tomography/CT (RECIST 1.1 versus PERCIST 1.0)

안영이,김성헌,박영하 대한영상의학회 2014 대한영상의학회지 Vol.71 No.2

Purpose: The aim of this study was to compare the diagnostic performances between the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) criteria on dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) and positron emission tomography Response Evaluation Criteria in Solid Tumors version 1.0 (PERCIST 1.0) criteria on positron emission tomography/CT (PET/CT) in evaluating the treatment response of neoadjuvant chemotherapy (NAC) in breast cancer patients. Materials and Methods: We compared MRI and PET/CT in the assessment of tumor response after NAC with the pathological response as the standard reference in 54 breast cancer patients. The tumor response was assessed by using the RECIST 1.1 criteria on DCE-MRI and PERCIST 1.0 criteria on PET/CT. The diagnostic performance of RECIST 1.1 and PERCIST 1.0 criteria was statistically analyzed and compared by receiver operating characteristic (ROC) analysis. Results: There were 21 responders and 33 non-responders according to the pathology. The discordant rate with pathological response was 37.0% for RECIST 1.1 and 55.6% for PERCIST 1.0. Twenty six patients (48.1%) were classified as responders in both MRI and PET/CT, but the final pathology showed non-response. In the ROC curve, the area under the curves (AUC) was 0.89 for RECIST 1.1 and 0.79 for PERCIST 1.0 (p < 0.001). Conclusion: The RECIST 1.1 criteria on MRI showed the better diagnostic performance than PERCIST 1.0 criteria on PET/CT for the response assessment of breast cancer after NAC, although there was no statistically significant difference between both (p = 0.15).

Treatment Response Evaluation of Breast Cancer after Neoadjuvant Chemotherapy and Usefulness of the Imaging Parameters of MRI and PET/CT

안영이,김성헌,강봉주,이아원 대한의학회 2015 Journal of Korean medical science Vol.30 No.6

This study was aimed to evaluate the ability of imaging parameters measured on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), diffusion-weighted MRI (DWI) and positron emission tomography/computed tomography (PET/CT) to serve as response markers in breast cancer after neoadjuvant chemotherapy (NAC). In 20 patients with breast cancer, DCE-MRI and DWI using a 3 T scanner and PET/CT were performed before and after NAC. DCE-MRI was analyzed using an automatic computer-aided detection program (MRCAD). The response imaging parameters were compared with the pathologic response. The areas under the curve (AUCs) for DCE-MRI using MR-CAD analysis, DWI and PET/CT were 0.77, 0.59 and 0.76, respectively. The combination of all parameters measured by MRCAD showed the highest diagnostic performance and accuracy (AUC = 0.77, accuracy = 90%). The combined use of the parameters of PET/CT with DCE-MRI or DWI showed a trend toward improved specificity and negative predictive value (100%, 100%, accuracy = 87.5%). The use of DCE-MRI using MR-CAD parameters indicated better diagnostic performance in predicting the final pathological response compared with DWI and PET/CT, although no statistically significant difference was observed. The combined use of PET/CT with DCE-MRI or DWI may improve the specificity for predicting a pathological response.

Synovial Chondrosarcoma in the Hand and Wrist: A Case Report

안영이,김지영,강석진,강용구,백준현 대한영상의학회 2010 대한영상의학회지 Vol.62 No.1

Synovial chondrosarcoma is extremely rare and arises de novo or from malignant transformation of synovial chondromatosis. It commonly involves large joints, such as the knee or hip. Here, we present an unusual case of synovial chondrosarcoma from synovial chondromatosis in the hand and wrist, clearly demonstrating the characteristic findings on plain radiograph and MR imaging.

안영이,김성헌,차은숙,김현숙,강봉주,박창숙,정나영,황인용,윤수경 대한영상의학회 2011 Korean Journal of Radiology Vol.12 No.1

The purpose of this paper is to show the clinical and radiologic features of a variety of diffuse, infi ltrative breast lesions, as well to review the relevant literature. Radiologists must be familiar with the various conditions that can diffusely involve the breast, including normal physiologic changes, benign disease and malignant neoplasm.

펑샤오강(馮小剛) 영화 <나는 반금련(潘金蓮)이 아니다>에 관한 소고

안영은 한국중어중문학회 2022 中語中文學 Vol.- No.89

<나는 반금련이 아니다>는 펑샤오강의 일련의 민간서사 가운데 매우 독특한 풍격을 보여준다. 기존의 민간서사가 개인의 삶과 운명에 초점을 맞추고 있다면, 이 영화는 주인공 리쉐롄이 맞닥드린 상황과 처지를 현대중국의 다양한 문제들(주택분배, 산아제한정책, 관료사회 운영체계 문제, 중국민간과 권력계층 간의 갈등)속에 풍자적이고 해학적인 방식으로 드러냄으로써 현대중국 사회의 이면을 들여다 볼 수 있는 계기를 제공한다는 점에서 서사방식의 변화와 발전된 양상을 보여준다. 물론 상업적 부분에 대한 고려도 자연스럽게 수반하고 있다. 예컨대 중국의 사회문화적 맥락에서 반금련(潘金蓮)이란 이름은 선정(煽情), 흉살(凶殺), 난륜(亂倫), 결혼, 애정 비극 등 지나치게 많은 의미와 상상적 요소를 담고 있기에 제목 자체가 불러오는 소환력 또한 간과할 수는 없다. 펑샤오강은 2016년이란 시대적 조류 속에서 과거 농후했던 상업적 색채를 과감하게 줄이고 사회적 문제들을 새로운 예술적 탐색 과정에 녹여냄으로써 예술가로서의 시대적 책무와 시장화 간에 균형을 유지하면서 또 다른 색채의 펑샤오강 영화를 선보인다. 본 논문에서는 첫째, 펑샤오강 영화의 서사적 특징과 펑샤오강이 <나는 반금련이 아니다>의 언설방식으로써 선택한 다양한 영상 프레임의 운용을 살펴볼 것이다. 둘째, 리쉐롄 고소사건이 20여 년 전 장이머우(張藝謀)가 제작한 영화 <치우쥐 소송(秋菊惰官司)> 속 서사 및 캐릭터의 발전된 양상이라는 점에 착안하여, 20년 후 리쉐롄 고소사건은 어떻게 시대를 반영하고 있는지를 살펴볼 것이다. 셋째, 리쉐롄 자신이 반금련이 아님을 인정받기 위해 펼쳤던 고소 대장정 과정에서 어떻게 결국엔 반금련이 되었는지를 논의하게 될 것이다.
