전태주 대한영상의학회 1995 대한영상의학회지 Vol.32 No.5

Authors reviewed mammographic ultrasonographic and MRI findings a patient with breast cysticercosis, which wasoperated and pathologically proved. mammography showed a 1cm sized round radioopaque lesion with curvilinearcalification, which was located near the pectoralis major muscle. Ultrasonografic findings showed heterogenoushypoechoic cystic lesion with internal hyperechoic nodule and posterior acoustic shadowing. T2WI and protondensity image MR image showed low signal intensity with cresentic high signal intensity portion. 2D-FLASH dynamicMRI showed intermediate signal intensity and peripheral signal void area, which was not enhanced with Gd-DPTA. Thepossibility of cysticercosis can be considered be considered when a cytic lesion is discovered near the pectoralismuscle in a patient living in an endemic area.

폐선암의 전산화단층촬영 소견

전태주 대한영상의학회 1996 대한영상의학회지 Vol.34 No.3

Purpose : To evaluate CT findings of primary adenocarcinoma of the lung and to assess distant metastasis atthe time of diagnosis. Materials & Methods : CT findings of 150 patients with adenocarcinoma, confirmed byhistopathologic methods, were classified as central or peripheral lesions and pattern analysis of typical findingsnoted in this cancer was carried out. Intra and extrathoracic metastases of adenocarcinoma were also investigated.Results : Of 150cases of adenocarcinoma of the lung, 121 were found to be of the peripheral type and 29 were ofthe central type. These peripheral lesions comprised 105 nodules, 11 consolidations, four cavities and one linearlesion, while the central lesions consisted of 19 cases of atelectasis and tens of bronchial wall thickening. Lungto lung(nine cases), lymphangitic(five cases), and pleural metastasis(16 cases) were presented as intrathoracicmetastasis, while bone(17), brain(six), liver(two) and adrenal metastasis(one case) were presented asextrathoracic metastasis. Conclusion : The most common radiologic finding of adenocarcinoma is a peripheral singlemass or nodule but consolidation, cavity or tubular lesions, as well as atelectasis or bronchial wall thickeningalone can be presented as unusual findings of adenocarcinoma. As a consequence, it is in many cases difficult todifferentially diagnose. Distant metastasis was also noted in many cases of early T-stage lesion, so tosuccessfully manage the patient, careful evaluation of the metastasis is essential.

복부 외상 후에 발생한 주췌관 가로절단과 동반된 가성낭종의 췌관 스텐트 삽입 치료 1예

복부 외상으로 인한 췌장 손상은 드물지만 이환율과 사망률이 높다. 주췌관의 손상이 있는 경우 초기 합병증으로 췌장 누공, 가성낭종, 농양, 출혈, 췌장염 등이 발생할 수 있다. 췌장 손상으로 발생한 가성낭종의 치료로 경과 관찰, 피부경유배출, 내시경 배액술 및 외과 치료가 포함된다. 피부경유배출의 경우 국소 마취 후에 전산화단층촬영술이나 초음파 유도로 시행하므로 비교적 안전하고 효과적이나 주췌관의 손상 정도와 부위가 크면 췌장 절제가 필요할 수 있다. 췌관 스텐트 삽입술은 급성, 만성 췌장염, 가성낭종, 췌관 협착, 췌장 누공 등에서 시행되어 적용 범위가 넓어지고 있다. 췌장 외상 후에 발생한 가성낭종 치료에서 주췌관의 부분 파열과 동반된 경우에는 췌관 스텐트 치료가 효과적이나 주췌관의 완전 가로절단과 함께 발생하는 경우는 외과 치료가 주치료이며 췌관 스텐트 치료의 효과는 아직 명확하지 않다. 이에 저자들은 복부외상 후에 발생한 주췌관 가로절단과 동반된 가성낭종을 외과 치료 없이 췌관 스텐트 삽입으로 치료한 1예를 경험하였기에 보고하는 바이다.

뇌조직의 자화전이율:정상치 및 TR/TE의 영향

전태주 대한영상의학회 1995 대한영상의학회지 Vol.32 No.4

Purpose : Magnetization transfer imaging(MTI) is a new imaging contrast technique. Our MT pulse sequence isdesigned as fixed time interval between echo and MT pulse. This study was performed to evaluate the influence ofvariations in TR/TE on MTR in T1 weighted image of normal brain tissue on this kind of MT pulse sequence.Materials and Methods : Seven healthy volunteers in twenties of age as the objectives, MRI was taken under variousTR/TE( TR/TE ; 700/14, 650/14, 750/14, 700/20 and 1500/20msec). MTR was calculated from signal intensities,measured at the same point in both pre and post MT images and statisticslly analized. The MR imager used in thisstudy was 1.0T Magnetom 42SP(Siemens, Erlangen, Germany) and the parameters of additional MT pulse sequence wereoffset 1,000Hz and bandwidth 250Hz, and posteriorly located to echo with 7.7 msec fixed interval. Offset of thisMT pulse was variable. Result : In white matter of brain tissue from a normal person, MTR was 34-39%(average 37%)for TR and TE of 700/14 in T1WI and 33-36%(average 35%) for TR/TE of 650/14 , and 34-38% (average 35%) for TR/TEof 750/14 which showed no statistical difference. However, in case of 1500/20 of TR/TE, MTR was 26-28%(average26%) which is statistically significant. With TR/TE of 700/14 as the standrd value, the MTR of gray and whitematter were 37% and 29% irespectively, showing a definiate difference of statistical means. Signal from CSF inventricles is rarely influenced by MT pulse. Conclusion : Conclusively, a subtle variation in TR/TE in T1WI haslittle influence on MTR but wide range of variation in TR/TE as in proton density image induces significantdifference in MTR on this kind of MT pulse sequence. Therefore, the exchangeable usage of MTR data would bepossible in narrow range of TR/TE change but difficult in wide range of variation.

만성 췌장염에서 통증, 외분비 및 내분비 기능장애의 치료

전태주 ( Tae Joo Jeon ) 대한췌장담도학회 2020 대한췌담도학회지 Vol.25 No.1

만성 췌장염은 점진적인 염증성 질환으로 췌장의 비가역적인 손상 및 섬유화를 유발한다. 이러한 과정은 통증과 외분비장애, 내분비장애와 같은 췌장기능 이상을 일으킨다. 통증은 가장 흔한 증상으로 췌장의 구조적 변화와 신경병적 이상으로 생긴다. 통증 평가는 강도, 지속 시간, 빈도, 삶의 질 등과 연관하여 다각도로 평가해야 한다. 통증의 치료를 위하여 금주, 금연이 필수이다. 진통제 사용은 세계보건기구 지침을 따르며 그 외에 췌장효소, 항산화제, 항우울제, 항경련제 등을 사용할 수 있으나 표준화된 지침은 없고, 상황에 따라 사용할 수 있다. 외분비장애에 췌장효소를 투여할 수 있으며 크기가 2 mm보다 작은 장피복형 최소 미세구이면서 리파아제 함량이 최소 40,000-50,000 USP인 것이 좋다. 식사와 함께 복용하고 치료반응이 없으면 용량을 늘리거나 프로톤펌프억제제나 항생제를 추가해 볼 수 있다. 만성 췌장염과 관련된 당뇨병은 3c형 당뇨병으로 조기 진단 및 매년 추적 검사가 중요하며 1형과 2형 당뇨와의 감별도 중요하다. 적절한 약물 치료에 대한 지침은 현재 없는 상태로 당조절이 잘되고 저혈당이 오지 않도록 생활 개선을 해주는것이 중요하다. 영양실조가 심할 때는 1차적으로 인슐린 사용이 권장된다. Chronic pancreatitis is the progressive and inflammatory disease which will result in the irreversible destruction and fibrosis of the pancreas. These processes cause chronic pain and pancreatic dysfunctions such as exocrine and endocrine insufficiency. Medical treatment for chronic pancreatitis would be reviewed in this article. Abdominal pain should be accessed by using multidimensional approach including pain intensity, pattern, impact on daily function and quality of life. Abstinence from alcohol and smoking should be strong recommendation. The guideline for analgesic therapy follows the principles of the “pain relief ladder” by World Health Organization. The pancreatic enzyme replacement should be considered when exocrine insufficiency is suspected. Enteric-coated microspheres or mini-microspheres of <2 mm in size with a minimum lipase dose of 40,000-50,000 United States Pharmacopeia are the recommended preparations. These preparations should be taken with main meals. Increasing the oral enzyme dose and the addition of a proton pump inhibitor could be considered in cases of unsatisfactory clinical response. Diabetes mellitus secondary to chronic pancreatitis is classified as Type IIIc diabetes mellitus. Optimal pharmacological treatment has not been established yet but should promote life-style changes, which may improve glucose control and avoid hypoglycemia. In patients with severe malnutrition, insulin therapy is recommended as a first choice. Treatment for chronic pancreatitis can include medication, therapeutic endoscopy, interventional radiology, and surgery. Among them, medical treatment is the most important and should be well understood.

Adrenal cysts are rare lesions usually discovered incidentally during surgery, or at the time of autopsy. Most adrenal cysts are generally asymptomatic and small, less than 10 cm in diameter. When adrenal cysts enlarge sufficiently, they cause pain and gastrointestinal disturbances or become palpable. When cystic lesions in upper abdomen are found, many cystic lesions such as hepatic, splenic, renal and pancreatic cysts should be considered. It's difficult to differentiate between benign and malignant lesions. Usually these cystic lesions have been excised to rule out malignancy. Herein we report a case of adrenal endothelial cyst which was detected in a 63-year-old female patient during a routine health examination by ultrasonography.(Korean J Med 62:680-684, 2002)
