초록

유방암 중에서 가장 발생율이 높은 침윤성 관상피암을 대상으로 생체 국소 수소핵 자기공명분광법(localized in vivo $^1H$ MRS)을 시행하여 조직학적 형태에 따른 자기공명 분광상(MR spectroscopy)의 특성을 분석하고자 본 연구를 실시하였다. 조직학적으로 침윤성 관상피암으로 진단 받은 환자 40명을 대상으로 하여 종양이 있는 부위를 실험군으로 정하였고 종양이 없는 반대쪽 부위를 대조군으로 정하여 3.0T MR scanner를 이용한 수소핵 자기공명분광영상으로 검사를 시행하여 영상 및 분광 정보를 얻었다. 유방암 환자 40명 중 34명(85%)에서 3.2 ppm 분광정점을 확인할 수 있었고 MRS상 3.2 ppm에서의 분광정점 발현여부를 유방암의 진단 기준으로 선택하는 경우 민감도는 85% (34/40), 특이도는 92.5% (37/40), 양성예측율은 100% (34/34), 음성 예측율은 86% (37/43)이었다. 정상 조직의 1.3 ppm에서의 분광정점을 진단 기준으로 정할때 민감도는 92.5% (37/40), 특이도는 85% (34/40), 양성 예측율은 100% (37/37), 음성 예측율은 91.8% (34/37)이었다. $^1H$ MRS방법이 유방암의 진단에 이용될 수 있는 가능성을 제시하였고 추후 지속적인 연구를 통해 임상적으로 진단 및 치료 판정에 널리 이용될 수 있을 것으로 사료된다.

To evaluate the potential value of $^1H$ Magnetic resonance spectroscopy (MRS) for detecting and characterizing invasive ductal carcinoma of breast. We conducted $^1H$ Magnetic resonance spectroscopy (MRS), using a 3.0T MR scanner, on 40 patients who were histologically diagnosed to have invasive ductal carcinoma (IDC); tumor areas of the patients were designated as experimental samples, and non-tumor areas as control samples. The peak at 3.2 ppm is characteristically intense and observed in 34 cases of the total 40 invasive ductal carcinoma (sensitivity 86.2%; specificity 100%; positive predictive value 100%; negative predictive value 60%). In constrast peak at 1.3 ppm is characteristically intense and observed in normal breast (sensitivity 86.2%; specificity 100%; positive predictive value 100%; negative predictive value 60%). The study shows that $^1H$ MRS can effectively discriminate invasive ductal carcinoma from normal breast in most cases. It also demonstrates the feasibility of localized in vivo $^1H$ MRS technique as a new diagnostic modality in the detection of breast tumor.
