Scanogram is that combine several practical images into one image to observation. So it is an important consideration in many clinical situation such as iliac measurement, leg alignment measurement and Scoliosis. Currently, scanogram examinations are mainly conducted for children and elderly patients. In this study, in order to apply the longbone detector to children or elderly patients who are difficult to cooperate with, we compared the longbone detector from D equipment with the G equipment discovery 656 Puls equipment in reproducibility of images, distribution of irradiation dose, scattering dose, irradiation time and image acquisition time. D equipment took more than twice as much time as G equipment. The scattered dose generated about 50% more G equipment than D equipment. In the whole spine scanogram and the measurement length of the lower leg, D equipment was also measured longer than G equipment. However, both methods did not show much difference from the CT scanogram, so there was no problem in measurement. The height of the thyroid radiation dose of G equipment was produced more radiation than D equipment. However, the longbone detector deviated from the x-ray center line relative to the tube rotation method, and was measured lower by the directionality of the measuring instrument, so that the error could not be corrected. In the conclusion of study, using the longbone detector is excellent for applying to children or elderly patients to reduce scattering dose. However, using CR may be useful to normal patients. Because, the image quality may deteriorate due to an imbalance of dose difference in thickness depending on the body part. So, it is useful to using a compensation filter or tube rotation method when we take a whole spine scanogram.

The accurate measurement for a long bone have taken an important part in orthopedics surgical diseases when the length of extremities is different each other. However, it is true that various kinds of methods to search for the accurate measurement on used in medical centers. In this study, we measured the real length of long bone for CT Scanogram and F.F.D by 100cm and 200cm in the angle of inclination $0^{\circ},\;3^{\circ}$ and $7^{\circ}$. This method will be useful to diagnose and treat patients more accurately.

골성 골단에서 발생하는 혈관종은 극히 드물어서 그 보고를 찾아보기가 쉽지 않다. 우측 슬관절부 동통과 굴곡 구축을 주소로 내원한 5세 환아로 단순 방사선 및 자기공명영상 소견상, 대퇴골 원위부 골단 및 근위부 경골에서 병변을 보였으며, 생검한 결과 혈관종으로 진단되었다. 8년간 추시 관찰하였으며, 대퇴골 원위부 골단에 발생한 혈관종은 치유되었으며, 경골 근위부 골단에 발생한 병변도 치료없이 자연적으로 소실되었다. 또한, 하지 길이의 단축이나 슬관절 기능 장애는 발생하지 않았다.

The purpose of this study was to compare the diagnostic performance of Waters' and panoramic view; maxillary sinus posteroanterior and lateral scanography of Scanora/sup (R)/ for mucosal thickening of maxillary sinus as well as to identify the utility of Scanora/sup (R)/ for the detection of maxillary sinus disease. The assessment was done at 66 maxillary sinuses in 45 patients and the results were as follows ; 1. Estimation of presence or absence of mucosal thickening. The sensitivity, specificity, and positive and negative predictive value of maxillary sinus posteroanterior and lateral scanography were 0.865, 0.860, 0.921, and 0.805 respectively and slightly higher than those of Waters' and panoramic views, which were 0.832, 0.835, 0.903, and 0.728 respectively. However, paired t-test showed no significant differences in the diagnostic performance of the two pairs of imaging modalities. 2. Estimation of the types of mucosal thickening. The diagnostic accuracy for type I, II, III was 75.3％ on Waters' and panoramic view; 77.9％ on maxillary sinus posteroanterior and lateral scanography. It was higher on the latter ,but showed no significant differences from that on the former. 3. Reliability of interpretation. In itraobserver and interobserver agreement, both overall rates of agreement and kappa-value were slightly higher on maxillary sinus posteroanterior and lateral scanography than on Waters' and panoramic views. There was no significant differences between the two pairs of imaging modalities. These results suggested that scanogram is a useful diagnostic radiography as well as Waters' and panoramic views for detection of maxillary sinusitis.

목적: 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서 수정된 Pull-Out 봉합술을 시행한 후 임상결과를 알아보고자 하였다. 대상 및 방법: 2006년 3월부터 2011년 2월까지 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서 수정된 Pull-Out 봉합술을 시행 받은 환자 74예 중 최소 12개월 이상 추시가 가능하였고 동반 질환이 있는 환자를 제외한 40예를 대상으로 하였다. 평균 연령은 49.5세 였다. 체중 부하 단순 방사선 사진에서 Kellgren과 Lawrence분류상 정상이나 초기 퇴행성 관절염(1-2군)이며, 체중 부하 방사선 하지 scanogram검사에서 역학적 축을 측정하였을 때 내반 변형이 없거나 5도 이내의 경도의 내반 변형 환자를 대상으로 하였으며, 연골 손상의 정도는 수술 중에 Outerbridge 분류를 사용하였으며, 임상적 결과는 Lysholm knee score를 사용하였다. 결과: 최종 추시상 Lysholm Knee Score는 술전 63.9점(범위; 53~78점)에서 술후 86.3점(범위; 72~94점)으로 향상 되었다 (p>0.05). 봉합술이 완전 실패한 경우는 40예 중 3예였다. 이는 현재 경과 관찰중에 있다. 관절연골 병변은 20예에서 내측 대퇴골 체중 부하 부위에 있었고, Outerbridge 분류상 1기 12예, 2기 5예, 3기 3예였다. 결론: 내측 반월상 연골 후각부 뿌리 파열의 치료에 있어서는 먼저 환자의 관절염이나 내반 변형 같은 동반 질환 여부를 가려내는 것이 중요하며, 경도의 관절염이나 내반 변형이 있는 40~60대 중년의 환자에서 수정된 Pull-Out 봉합술을 시행할 경우 비교적 양호한 임상적 결과를 얻을 수 있을 것으로 사료된다.
