목적 : 급성심근경색을 진단하는데 있어 심장자기공명영상의 유용성을 알아보고, 생존심근을 평가하는데 있어 Tl-201 심근관류 SPECT와 비교하고자 하였다. 대상 및 방법 : 흉통 및 호흡곤란이 있는 환자 중 심장자기공명영상과 Tl-201 SPECT를 시행한 17명을 후향적으로 조사하였다. 심장자기공명영상에서는 T2강조영상에서 심벽의 고신호 강도 유무, 영화영상에서 심벽 운동, Gd-DTPA 조영 증강 후 좌심실 벽의 관류 결손 및 주입 15분 후의 지연조영증강 유무를 평가하였다. T1-201 SPECT에서는 아데노신 부하 영상과 휴식기 영상을 얻어 관류 결손 유무와 관류 결손시 가역성 여부를 평가하였다. 결과 심장자기공명영상과 T1-201 SPECT 모두 급성심근경색을 진단하는데 통계적으로 의미가 있었고, T2강조영상, T1-201 SPECT, 지연조영증강 및 심벽운동 순으로 연관성이 있는 것으로 나타났고, 관류 결손은 통계적 유의성이 없었다. 생존심근 평가에 있어서는 두 검사간 유의한 차이가 없었으며, T2강조영상과 관류영상에서 T1-201 SPECT와 높은 일치율, 지연조영증강 및 심벽운동은 낮은 일치율을 보였다. 결론 : 심장자기공명영상은 급성심근경색을 진단하는데 매우 유의한 진단율을 보였고, 생존 심근여부의 판단에 있어 SPECT와 높은 일치율을 보였다. 그러나 각 검사별 판독 기준과 방법에서 많은 연구가 필요할 것으로 생각된다. Purpose : To assess the usefulness of cardiac MR imaging (MRI) in the diagnosis of acute myocardial infarction and in the assessment of myocardial viability in comparision with T1-201 SPECT. Materials and Methods : We retrospectively studied 17 patients who complained of chest pain and dyspnea with cardiac MRI . The patients were evaluated for the presence or absence of high signal intensity on T2-weighted image (T2wI), abnormal wall motion on 2D-FIESTA, perfusion defect on Gd-DTPA enhanced T1WI, and delayed myocardial enhancement on 15-minutes delay Gd-DTPA enhanced T1WI. The results were correlated with the images on T1-201 SPECT, taken at rest and stress, through which reversibility of perfusion defect was assessed. Results : Both cardiac MRI and T1-201 SPECT proved to be useful methods for diagnosing acute myocardial infarction. In order of decreasing correspondence, T2WI, T1-201 SPECT, delayed enhancement study, and wall motion images all showed significant statistical correlation with the clinical diagnosis of myocardial infarction. Perfusion MRI, on the other hand, showed no significant statistical difference was found between T1-201 SPECT and cardiac MRI. The results on T2WI showed high accordance with those on Tl-201 SPECT, while delayed myocardial enhancement and wall motion studies showed no agreement with Tl-201 SPECT. Conclusion : Cardiac MRI is useful method for diagnosis of acute myocardiac infarction. With respect to the assessment of myocardial viability, the results obtained on cardiac MRI showed high agreement with those on Tl-201 SPECT. However, further study is necessary at this point for standardization and establishment of the methods for assessing myocardial viability on cardiac MRI.

낭성섬유증(cystic fibrosis)은 상염색체 열성유전질환으로 침샘,땀샘,췌장,대장,기관기관지 등의 외분비선의 이상에 의해 나타나는 질환이다.백인에게는 비교적 흔한 유전질환이나 한국 등의 아시아 국가에서는 드문 질환이다.1988년에 한국에서 한 예가 발표되었으나 진단에초점이 맞춰져 있었고 방사선학적 소견에 대한 발표는 없어 당시 낭성섬유증으로 진단되었던 소아의 추적검사를 중심으로 방사선학적 소견을 보여주고자 한다. Cystic fibrosis is a hereditary disease involving recessive transmission. The fundamental abnormality consists of the production of abnormal secretion from a variety of exocrine glands such as salivary and sweat glands and those of the pancreas, colon, and tracheobronchial trees. Cystic fibrosis is the most common lethal genetically transmitted disease among whites, but is uncommon in Asians, including Koreans. Although a case involving a Korean was reported in 1988, the focus was diagnosis rather than the radiological findings. In the case of cystic fibrosis we now describe, the focus is inverted: we enphasise the reported in 1988, focusing on radiologic findings

Replacement lipomatosis in grafted kidney is a rare complication, and it consists of abnormal fatty proliferation. We report a patient with replacement kidney lipomatosis in grafted kidney. Abdominal CT was performed for evaluation of vague abdominal pain, and 3.9 cm sized mass was incidentally detected in the grafted kidney. Presumptive diagnosis of mass was lymphoma or other tumorous conditions. Graft was removed surgically, and it was confirmed as lipomatosis. Renal lipomatosis is rare but it should be included as a differential diagnosis of mass in transplanted kidney.

Normal lumbar vertebrae function only when soft tissues are in position, constituting vertebral body, discs and facet joints. Considering the mechanism of supporting bodily weight, the widest movement of vertebral column reaches a lumbar sacral joint to cause structural changes. The fact is proved that lumbago is the damage of lumbar vertebrae accompanied with the change of soft tissues surrounding lumbar vertebrae, rather than simple pain in a certain region. It is based pan the mechanism of vertebral body and intervertebral discs in the anatomical structure of the lumbar region. In my opinion, it is necessary to prove mare accurately the cause of lumbago, escaping from the conventional cause of the abnormality of disc.
