전우기,한창열 인제대학교 1980 仁濟醫學 Vol.1 No.1

요추핵탄출증의 수술전후의 척추강높이 요천각, 국소적척추만곡등 단순 X선 사진상 변화 소견을 비교 검토하였다. In the great majority of cases with the lower back pain, the lumbar herniated disc is one of the common causes. The plain radiographs of preoperative and postoperative periods were studied in 76 cases which were surgically verified as lumbar herniated disc at Baik Hospital. The following results were obtained : In preoperative plain radiograph, 16.9% of 76 cases revealed no specific abnormlity. The most common positive finding was the straighteing of the lumbar curvature (56.6%). Other common positive finding was a relative narrowing of the intervertebral disc space (46.1% The greatest incidence of preoperative intervertebral disc space was between 0.8cm and 1cm (48.8% of cases) and next 1.1cm.-1.3cm(37.8%) The over-all mean of lumbosacral angle in preoperative plain radiographs was 29.7˚. The greatest incidence of lumbosaral angle was between 31˚ and 40˚ (31.6% of cases) and next 21˚-30˚(30.3%). Study of postoperative(after 1 month-1 year) radiograph i) Postoperative plain radiograph showed the future decrease of disc space in 39 cases(51.3%) than preoperative one. ii) Postoperative lumbosacral angle showed further increase in 35 cases (46%) than preoperative iii) 18.6%(8 cases) of 43 cases with preoperative straightening of lumbar curvature showed the normal lumbar lordosis in postoperative radiograph. iv) 93.9%(31 cases) of 33 cases with preoperative normal lumbar lordosis also showed normal lordosis in postoperative radiograph. v) 85.7%(12 cases) of 14 cases with preoperative local lumbar scoliosis showed no scoliosis of lumbar spines in postoperative radiograph.

전우기,이성우,한창렬 인제대학교 1981 仁濟醫學 Vol.2 No.4

유구치석회화 상태를 통해서 신생아의 임신년령을 측정했다. There have been suggested many different methods dertermining fetal age by the roentgenographic devises, but we have suggested a study of the deciduou molars. These teeth are frequently seen on lateral views of the neonatal chest. Therefore we have utilized this method about the One-hundred Korean neonates. We have found the 2nd deciduous molar usually showed no calcification of the enamel prior to 35 weeks of geatation, whereas the ratio of the calcification of the 40 weeks was 100%. Since the mandible is included on most chest films, it is easy to glance at the jaw and estimate the gestational age.

초음파 촬영 및 Tc-99m-HIDA를 이용한 담낭염의 진단적 평가

전우기,한창렬 인제대학교 1983 仁濟醫學 Vol.4 No.3

저자들은 1982년 6월부터 1983년 1월까지 만 8개월간 본 백병원에서 담낭염으로 의심됐던 총 62명의 환자들을 대상으로 하여 초음파 촬영 및 Tc-99m-HIDA 신티그래피를 실시하고 환자들의 최종 진단 결과를 토대로 분석한 결과 초음파 촬영은 담낭염이 의심되는 환자의 첫번 진단 방법으로 유용하고 Tc-99m∼HIDA 신티그래피는 돌이 없는 담낭염, 즉 초음파 촬영상 담낭벽의 4mm이상의 비후성과 담낭의 가장 넓은 직경이 5cm 이상이었던 경우에 유용함을 알 수 있었다. A prospective study of 62 cases was performed on patients with suspected cholecystits who were evaluated by cholesonography and 99mTc-HIDA cholescintigraphy at Department of Radiology, Paik Hospital during the period of 8 months from June, 1982 to January, 1983. * Criteria is determined for sonographic diagnosis of acute and chronic cholecystitis. 1) Visualization Vs. Nonvisualization of a fluid-filled gallbladder in the right upper quadrant. 2) Presence or absence of gallstones (echogenic foci with distal acoustic shadows) if the gallbladder was seen. 3) Gallbladder wall thickness measured at a point in the wall perpendicular to the transducer beam-4mm≤abnormal case. 4) Gallbladder shape (round Vs oval). 5) The greatest transverse diameter of the gallbladder-5cm≤abnormal case. *1) Normal HIDA scan was considered if the gallbladder was visualized within 2hr after injection. 2) Abnormal HIDA scan was considered if radioactivity was detected in the small bowel, but not in the gallbladder, 2hr after injection. Our datas were as fellows: In acute cholecystitis, 100% (19/19cases) had abnormal sonograms and the most common finding of cholesonography was thickened wall of gallbladder and 100% (19/19cases) had abnormal HIDA scan. In chronic cholecystitis, 100% (32/32cases) had abnormal sonograms and most common finding of cholesonogrophy was gallstones with thin walled and 66% (21/32cases) had abnormal HIDA scan. In differentiating normality from those with all types of gallbladder disease, HIDA sensitivity and specificity were 86% and 100%, respectively, while sonography had 100% sensitivity and 98% specificity. Data support the use of sonography as the initial imaging procedure for the patient with suspected cholecystitis. 99mTc-HIDA is useful in those cases without stones which exhibit criteria for Gall Bladder abnormality.

한창열,이성우,유필문,전우기,전정동 인제대학교 1985 仁濟醫學 Vol.6 No.1

저자는 당뇨병 환자 중 71명의 폐결핵 환자에 대한 흉부 사진상 폐결핵 변화를 관찰하고 문헌적 고찰하였다. We selected seventy one pulmonary tuberculous patients (6.271) among 1150 diabetic patients which were diagnosed at Paik Hospital, Inje Medical College from Jan. 1981 to Jun. 1984. It was found the results as follows. 1.Radiological extend of pulmonary tuberculosis was as follows: minimal 45.1%, moderately advanced 46.5%, far advanced 8.4%. 2.Pulmonary tuberculosis in diabetic patient was most prevalent in 50 decade and 60 decade. It tended that the more taking of age, the more having increase pulmonary tuberculosis. 3.We observed no correlation between FBS and extend of pulmonary tuberculosis on a chest roentegenogram. 4.The longer the duration of diabetes mellitus, the higher incidence of pulmonary tuberculosis. However, there was no correlation between duration of diabetes mellitus and extend of pulmonary tuberculosis on chest roentgenogram. 5.The pulmonary tuberculosis was predominantly in upper lobes in 69.1% and the lower lobe was affected in 11.2%.

전우기,한창렬 인제대학교 1986 仁濟醫學 Vol.7 No.3

생후 1일 내지 12주 되는 신생아와 영아에서 복부 영역이 포함되어진 흉부 정면 사진 159매를 통하여 糞 (분) 음영을 관찰한 결과 소아에서 정상적으로 볼 수 있는 비누거품 양상의 분 음영이 대체로 생후 2주까지의 미숙아들에게서는 드물게 나타나고 나타난 경우에는 추적검사를 통하여 궤사성 장결장염의 예시로서 장막(漿膜)과 장근육 내의 가스 거품인 것을 알 수 있었다. A prospective study of abdominal and chest films of 128 babies without symptoms of intraabdominal disease, aged 1 day-12weeks, showed that the "bubbly fecal pattern" normally seen in adult and older children is rare in young premature babies in the first two weeks of life. Its presence should suggest the diagnosis of distal bowel disease, especially necrotizing enterocolitis, and demand close clinica1 and possibly sequential radiological follow-up.

저자들은 CT를 이용하여 정상 봉신의 크기 모양 및 위치를 분석하여 한국인의 부신의 정상 범위를 정하였으며 CT는 재래의 방법보다도 쉽게 부신을 발견할 수 있었고 부신질환의 진단에 중요한 역할을 할 것으로 사료된다. Computed tomography is an excellent screening test far adrenal glands. Abdominal CT scans of 94 randomized patients without evidence of adrenal disease were reviewed to determine the location, size, and shape of both side normal adrenal glands. Results are as follow: 1.Adrenal glands are shorten in 85 patients. (90.4%) 2.Most of the right adrenal glands were linear in shape. (71%) 3.and most of the left adrenal glands were inverted V or Y, or triangular in shape. (79%) 4.Right adrenal glands. Mean length of 2.2cm, Width of 2.35cm, and Thickness of 0.59cm Left adrenal glands, Mean length of 2.5cm, Width of 2.09cm, and Thickness of 0.69cm. 5.Thickness of limbs was always less than 5mm.

백대일,전정동,전우기,이성우,한창열,박수성 인제대학교 1984 仁濟醫學 Vol.5 No.4

Detecting a cholesteatoma within complicated temporal bone by simple mastoid views is desirable but any single conventional projection appears to have reached the limit of its capacity. Several simple mastoid views must be combined to delineate cholesteatoma. Author reviewed various projections of simple mastoid views in 37 cases of cholesteatomas surgically proven at Paik Hospital Inje Medical College from 1981 to 1983 in order that diagnostic value of each view could be determined. The results were as fellows: 1.Detection rate of cholesteatoma with single projection only was followings: 75% with Owen view, 60% with Towne view, 59% with Law view, 44% with Stenvers view and 33% with Transorbital magnification view. 2.Detection rate of cholesteatoma with combined projections was followings: 60% with Law, Stenvers and Towne view combination, 83% with Law, Owen and Transorbital magnification view combination. 3.Cholesteatoma involved attic in 87%, antrum in 59% and middle ear in 33%, and the combined involvement(57%) was rather frequent than single involvement (43%) 4.The mastoid air cells were poorly pneumatized in cholesteatoma, ie. sclerotic pneumatization in 81% and diploic pneumatization in 14%.
