초록

본 연구는 자기공명 견관절조영검사 시 단위 부피당 가돌리늄 함유량이 2배 많은 1mmol/mL 조영제를 이용하여 T1 단축효과를 높임으로서 진단적 가치가 높은 영상을 얻을 수 있는 방법을 증명하고자 하였다. 2012년 1월부터 2013년 8월까지 0.5mmol/mL 함유량을 가진 기존의 조영제를 사용한 20명과 1mmol/mL 함유량을 가진 새로운 조영제를 사용한 21명 등 총 41명의 환자를 연구대상으로 하였다. 연구방법은 가돌리늄 함유량에 따른 대조도 차이를 알아보기 위하여, 견관절의 관절공간과 인접한 근육조직인 극상근, 그리고 상완골두의 신호강도를 각각 측정한 후 신호대잡음비와 대조도대잡음비를 비교하였다. 연구 결과, 가돌리늄 함유량이 높은 1mmol/mL 조영제가 0.5mmol/mL 조영제에 비해 SNR이 모두 높았으며(관절공간 38.01%, 극상근 8.40%, 상완골두12.78%), CNR도 가돌리늄 함유량이 높은 1mmol/mL 조영제가 높았다(관절공간과 극상근 48.96%, 관절공간과 상완골두 42.00%). 결론적으로 T1 단축효과를 높이는 다양한 방법 중 현실적으로 구현하기 용이한 가돌리늄 함유량이 높은 1mmol/mL 조영제를 이용하면 효율적으로 T1 단축효과를 높여 진단적 가치가 높은 영상을 얻을 수 있을 것으로 판단된다.

This research, used an contrast agent, which weighs about 1mmol/mL, of twice as much amount of gadolinum, per unit, for the test of magnetic-resonance shoulder arthrography. the reasearch which was carried out from January, of the year 2012 to August of the year 2013. consisted, of target of 41, patients including 20 ones, of whom an original, contrast agent of amount of 0.5mmol/mL, 21, ones of whom, a new, of amount of 1mmol/mL was used on, were the test target, in order to figure out the differences, according to the amount of gadolinum, according to the test results, the SNR of the contrast agent, of amount of 1mmol/mL, which is of high amount of gadolinum, was noticeably higher than the one of amount of 0.5mmol/mL(the percentage of joint space 38.01%, the supraspinous muscle 8.40%, head of humerus 12.78%). and CNR of the contrast agent, of amount of 1mmol/mL, which is of high amount of gadolinum, was higher than the one of amount of 0.5mmol/mL(the percentage of joint space and supraspinous muscle 48.96%, the one of joint space and head of humerus 42.00%). In conclusion, one of the methods of increasing the reducing effect of T1, is to use contrast agent of amount of 1mmol/mL, in order to increase the reducing effect of T1, acquire the visual of high testing quality.
