이민희,이영래,국신호,박해원,김승권,정은철,Lee, Min-Hui,Lee, Yeong-Rae,Guk, Sin-Ho,Park, Hae-Won,Kim, Seung-Gwon,Jeong, Eun-Cheol 대한영상의학회 2003 대한영상의학회지 Vol.49 No.4
목적: 골절 평가에 있어서 삼차원 디지털 회전 영상 (three dimensional digital rotational imaging, 3D DRI)의 적용 가능성과 유용성을 알아보고자 하였다. 대상과 방법: 임상적으로 골절로 진단되거나 의심된 총 16명에서 골절 병변 혹은 의심 부위(7예의 척추, 3예의 골반, 슬관절 등 기타 골절6예)에 대해서 단순 촬영술, single detector helical CT(HiSpeed advantage, GE Medical Systems, Milwaukee, WIS)를 이용한 2D CT(절편두께는 3 또는 5 mm, 피치는 1:1, bone algorithm)와 volume rendering 3D CT를 시행하고 3D DRI(Integris V-5000, Philips Medical Systems, The Nether-lands)를 실시하여 얻어진 삼차원 영상에서 다면적 분할과 회색조 조작의 후처리를 적용하였다. 3D DRI를 단순 촬영, 2D CT, 3D CT와 비교 평가하였다. 결과: 3D DRI에서 정확하고 추가적인 정보를 얻을 수 있었던 것은 모두 14 예(88%)었다. 두예는 3D DRI에서만 병변을 발견 하였고 한 예는 2D CT와 3D DRI 모두에서 병변을 발견하였다. 삼차원 영상에 대한 평가에 있어 16예 모두에서 3D DRI가 3D CT 보다 정확하고 많은 정보를 얻을 수 있었다. 단순 찰영 혹은 전산화 단층 촬영에서 골절이 발견된 13예 중 한 예를 제외한 12예(92%)에서 3D DRI는 골절의 분류에 영향을 주지 않았다. 결론: 3D DRI는 디지털 회전 영상에서 후처리가 가능한 삼차원 영상을 획득함으로써 정확한 해부학적 공간 해석력으로 빠르고 쉽게 골절을 진단하고 Purpose: To evaluate the usefulness and the application of three dimensional digital rotational imaging (3D DRI) by the evaluation of fractures. Materials and Methods: Sixteen patients with clinically diagnosed or suspicious fracture were involved in this study. The lesion or suspicious sites of all 16 cases were spines (n=7), pelvis (n=3) and so on (n=6; knee, elbow, ankle, wrist and foot). In all cases, conventional radiography, multiplanar 2D (slice thickness/pitch=3 or 5 mm/1:1)and volume rendering 3D reconstructed single detector helical CT (HiSpeed Advantage, GE Medical Systems, Milwaukee, WIS) scans and 3D DRI (Integris V-5000,Philips Medical Systems, The Netherlands) with multiplanar intersection and gray scaling as postprocessing technique were performed. 3D DRI was evaluated and compared with conventional radiography, multiplanar 2D CT and volume rendering 3D CT. Results: 3D DRI provided more detail and additional information in 14 cases (88%), comparing with 2D and 3D CT scans. Two fractures were revealed only on 3D DRI other than conventional radiography and CT scans and one case was revealed on 2D CT and 3D DRI. In all cases, we could acquired more detail and additional information from 3D DRI than from 3D CT in the acquisition of 3D imaging. 3D DRI didn’t change the classification of fracture in 12 of 13 cases (92%),which revealed the fracture on the conventional radiography or CT. Conclusion: 3D DRI can diagnose and evaluate the fracture rapidly and easily with anatomical and spatial resolution by acquisition of 3D imaging with postprocessing using DRI.

Paraquat has been a widely used herbicide in kore; since 1970, human ingestion results in acute renal fail- ure, hepatic dysfunction and progressive respiratory failure with high mortality rate. We have analyzed twenty three cases of acute para- quat poisoning who were admitted to Masan Koryo General Hospital from March 1986 to March 1987 and twenty cases of those were treated by hemodialysis. The following results were obtained. 1) Among 23 cases of acute paraquat poisoning, 16 cases were male and peak incidence was the fourth decade. 2) The major clinical sysmptoms and physical signs were sore throat and swallowing difficulty (100%), oral cavity ulcer (87%), fever (78.3%), jaundice (34.8%) and epigastric tenderness (30.4%). 3) Except 6 cases treated by early hemodialysis and 3 cases in early death, abnormal renal function and liver function were observed in 14 cases. 4) All of the 7 cases who ingested more than 50 ml of 24.5% paraquat died and 10 cases of the 16 cases who ingested less than 50 ml are alive. 5) The mortality rate was 56.5% and the cause of death was acute respiratory failure, acute renal failure and perforation of esophagus, in decreasing order of frequency.
