Purpose : To describe how a robust implementation of a radial 3D gradient-echo sequence with stack-of-stars sampling can be achieved, to review the imaging properties of radial acquisitions, and to share the experience from more than 5000 clinical patient scans. Materials and Methods: A radial stack-of-stars sequence was implemented and installed on 9 clinical MR systems operating at 1.5 and 3 Tesla. Protocols were designed for various applications in which motion artifacts frequently pose a problem with conventional Cartesian techniques. Radial scans were added to routine examinations without selection of specific patient cohorts. Results: Radial acquisitions show significantly lower sensitivity to motion and allow examinations during free breathing. Elimination of breath-holding reduces failure rates for non-compliant patients and enables imaging at higher resolution. Residual artifacts appear as streaks, which are easy to identify and rarely obscure diagnostic information. The improved robustness comes at the expense of longer scan durations, the requirement for fat suppression, and the nonexistence of a time-to-center value. Care needs to be taken during the configuration of receive coils. Conclusion: Routine clinical use of radial stack-of-stars sequences is feasible with current MR systems and may serve as substitute for conventional fat-suppressed T1-weighted protocols in applications where motion is likely to degrade the image quality.

Clinical observation was done on 290 cases of patients who were diagnosed as CVA with brain CT, TCD, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyung-Won University from 1st January to 31st December in 1996. 1. The cases were classified into the following kinds : cerebral infarction, cerebral hemorrhage, and transient ischemic attack. The most case of them was the cerebr진 infarction. 2. There is no significant difference in the frequency of strokes in male and female. And the frequency of strokes was highest in the aged over 50. 3. In cerebral infarction the most frequent lesion was the territory of middle cerebral artery, and in cerebral hemorrhage the most frequent lesion was the basal ganglia. 4. The most ordinary preceding disease was hypertension, and the next was diabetes. 5. The rate of recurrence was high in cerebral infarction. 6. The frequency of strokes seems to have no relation to the season. 7. The cerebral infarction occurred usually in resting and sleeping, and the cerebral hemorrhage in acting. 8. The course of entering hospital, most patients visited this hospital as soon as CVA occurred. And the half of patient visited this hospital within 2 days after CVA attack. 9. In the cases of patients who were unconscious at the admission, the prognosis was worse than that of the alert patients. 10. The common symptoms were motor disability and verbal disturbance. 11. The average duration of hospitalization was 27.4 days, and in case of cerebral hemorrhage the duration was prolonged. 12. The average time to start physical therapy was 13.3rd day after stroke in cerebral infarction and it was 19.9th day after stroke in cerebral hemorrhage. 13. The common complications were urinary tract infection, pneumonia, myocardial infarction and so on. 15. At the time of entering hospital, in most cases the blood pressure was high, but blood pressure was well controlled at the time of discharge. 16. Generally reported, hypercholesterolemia and hypertriglyceridemia are usually found in cerebral infarction. But in this study, they were found more frequently in cerebral hemorrhage than in infarction. 17, In the most cases, western and oriental medical treatments were given simultaneously. 18. In acute or subacute stage, the methods of smoothening the flow of KI(順氣), dispelling phlegm(祛痰), clearing away heat(淸熱) or purgation(瀉下) were frequently used. And in recovering stage, the methods of replenishing KI(補氣), tonifying the blood(補血) or tranquilization(安神) were frequently used.

골다공증은 골밀도와 골의 질로 구성되는 골의 강도가 손상됨으로 골절의 위험이 높아지는 골격질환이며, 최근 유병율이 점차 증가하고 있는 추세이다. 임상적으로 무증상인 경우가 많으며 방사선학적 검사인 단순 방사선 검사, 골 스캔, CT, MRI 등이 골밀도 및 골절의 진단에 유용하다. 골밀도의 정량적 검사로는 이중에너지 방사선 흡수법, 정량적 전산화 단층촬영이 사용되고 있다. 골다공증의 진단은 WHO 기준에 따라 T-score가 -2.5 이하일 경우 진단할 수 있다. 그 외에 생화학적 골표지자들도 진단에 도움이 된다. 골다공증 치료제는 골흡수억제제와 골형성자극제(formation stimulator)로 나눌 수 있는데 골흡수억제제로는 칼슘, 에스트로겐, 칼시토닌, 비스포스포네이트(bisphosphonate), 비타민 D 등이 있으며 골량을 증가시키는 골형성자극제로는 현재 부갑상선 호르몬이 유일하며 최근 strontium ranelate가 추가되었다. 일일 1200 mg의 칼슘과 800 IU 의 비타민 D 섭취가 권장되고 있으며, 폐경기 여성에서 에스트로겐이 효과가 입증되었고 골다공증으로 인한 통증에는 칼시토닌이 효과가 있다. 비스포스포네이트는 폐경 후 골다공증의 치료, 예방 및 스테로이드에 의한 골다공증 치료에 대해 FDA의 승인을 받았다. 폐경 후 골다공증의 치료, 예방에 사용되는 SERM은 골의 질을 향상시킴으로써 골절을 예방한다고 알려져 있다. 골형성자극제인 부갑상선 호르몬이 골절의 위험을 감소시킨다고 보고된 바 있으며, strontium은 최근에 개발된 약제로 3상 연구에서 골절 위험율 감소효과를 보였으나 더 많은 연구가 필요할 것으로 생각된다.

Modern medicine has early experienced the absence of mimesis and has been trying to replace the absence with objective grounds and experimental data. However, as medicine became science, the crisis of medicine spread more widely. Microscopic powers and violences are invisible, but individuals are powerless and vainly unable to resist. The anguish or introspection about the situation is sometimes described in stories such as An Engagement by Lee Eung Jun. An Engagement is mentioned in this article due to the writer's attitude, which shows his introspection and desire for harmony through the wounds of each trivial character. The writer is unceasingly talking about suffering people in his story and his seriousness enables readers to find his stronger sympathy over life and death than in any other medical stories. In fact, it is impossible for readers to comprehend the confusing propositions which the writer pours out, and even uncomfortable to read the story. Nevertheless, the propositions are always in contact with reality. Perhaps it is not the writer's confusing propositions that make us uncomfortable. It might be ourselves who are always alienated and starved. We can say that the characters' pains and wounds are phantom pains caused by the absence of mimesis. Since there is no affected area, their pains cannot be measured by only scientific medicine. However, the current medical profession regards objective research evidences as absolute truth and allows them to be the sole criterion. Although scientific skills such as DNA analysis and MRI scan can be the substitutes for doctors' judgment, so much of medicine is still interpersonal relationships. An Engagement. As a person promises to marry another, as all beings together in the world promise to subordinate to one another, every subject is consistently a valuable part of each other for the writer's eyes. He is aware that it is originally impossible to get engaged to the world, but he does not give up the possibility of genuine communication. In today's post-modernism society, where a large number of pathological views define the members and the world itself, endless questioning of existence and digging into pathology will be the only way to reduce the gap between individuals and their world. This article does not say that a literary work will lead the change of medical paradigm. It sprang from a desire for medical humanities to gain more interest of the medical field, where the encounter between literature and medicine is still unfamiliar, and to make medical education recognize the importance of humanities. Starting with this work, I believe that the humanities will help us to find the solution to the age of absence of mimesis and to the crisis of medicine.

RO는 경계가 좋은 고형종괴로써, 석회화를 포함할 수 있다. 조영전 CT 영상에서 신실질과 유사한 밀도의 균일한 종괴로 보인다. 조영 후 영상에서는 불균일하게 조영증강되는데, 역동적 조영증강 검사의 동맥강조기에서 주변부는 강하게 조영증강되었다가 시간에 따라 점차 조영이 약해지고, 중앙부는 시간에 따라 점차 조영이 증강되어 시간에 따른 조영증강의 부분적 역전현상이 관찰되었다. 이러한 영상의학적 특징이 관찰되는 경우에는 RO의 가능성을 시사할 수 있으며 이를 통해 환자의 예후를 예측하고 수술 방법을 술전에 결정하는데 도움을 줄 수 있으리라 생각한다.

간혈관종은 우리 몸에서 흔하게 발생하는 간병변 중 하나이다. 대부분 간혈관종은 증상이 없고 크기도 작기에 병리학적 검사로는 발견하기 어렵다. 따라서 간혈관종의 초기 발견 및 진단을 하기 위해서는 방사선 진단은 필수이다. 본 연구는 간혈관종에 대한 방사선진단인 전산화단층촬영, 자기공명영상, 핵의학, 초음파 검사의 방법에 대하여 연구하였다. 전산화단층촬영에서는 조영제를 이용한 삼중시기 기법, 자기공명영상 검사에서는 T1, T2 강조영상, 조영제를 이용한 동적 자기공명영상, 초고속 자기공명 영상기법, 확산강조영상의 방법, 핵의학에선 ^99mTc 표지 적혈구를 사용한 혈액풀 스캔방법, 초음파에선 색조도플러의 방법에 대해 연구하였다. 대부분의 간혈관종은 양성종양이기에 간세포암 등과 같은 악성 종양과 혼동하지 않게 주의하여 불필요한 시술을 방지해야 한다. 그러므로 정확한 진단을 하기 위해서는 간혈관종의 영상소견을 정확히 숙지하여 검사를 시행하는 것이 중요하다.
