The drug therapy for rheumatoid arthritis must be maintained constantly or for the whole life but is apt to induce the adverse effects in gastrointestinal or renal system. Therefor, newer methods are paid attention to reduce adverse effects. The thirty-two rat female separated into seven groups depending on the therapy or Freund's adjuvant applied: Normal group(n=8) not received anything, Positive control group(n=8) only received adjuvant, USC group(n=8) received continuous US, USP group(n=8) received pulsed US. The physical and radiological findings by thermal and non-thermal effects of ultrasound were evaluated in groups with continuous mode at 1 MHz, $0.5\;W/cm^2$ for 6 minutes and with pulsed mode (duty cycle 1:9) at 1 MHz, $0.5\;W/cm^2$ for 6 minutes. The result summarized followings. 1. Swelling of forepaw and hindpaw was significantly reduced in USP. 2. Arthritis indices in USP group were significantly reduced than those in PCG. 3. In naked eye and radiologic findings, swelling was significantly prevented in USP group but not in PCG. The change of swelling, arthritis index, gross feature in naked eye, radiologic finding were significantly improved in all groups except for USC group, taking care for using its continuous mode.

관강내 십이지장 게실은 드문 선천성 이상으로, 십이지장 점막으로 구성된 낭성 병변이며, 위장 출혈, 십이지장 폐색 또는 췌장염과 함께 나타날 수 있다. 이 논문에서는 25세 성인 여성에서 십이지장-십이지장 장중첩증과 재발성 췌장염의 합병증을 일으킨 드문 관강내 십이지장 게실의 사례를 보고하는 바이다. CT, MRI, 상부위장관조영술등의 영상 검사에서 십이지장의 중복낭을 의심하였으나, 수술로 절제된 조직에서 병리학적으로 고유근육층이 없는 관강내 십이지장 게실로 확진되었다.

십이지장 격막은 십이지장 관강 내의 불완전한 막으로 부분폐쇄 또는 간헐적인 완전 폐쇄를 일으킨다. 격막의 개구부 크기에 따라 폐쇄의 정도, 증상이 나타나는 시기, 영상의학적 소견이 다르다. 저자들은 이물질 섭취를 주소로 내원한 14개월 남아에서 우연히 진단된 십이지장 격막 증례를 보고하고자 한다. 복부 방사선 촬영, 상부 위장관조영술, 내시경, 수술 소견들을 종합하여 기술하였다. 저자들은 영아기에 섭취한 이물질의 배출이 지연되고 영상의학적 검사에서 이물질의 위치가 다양하게 변화할 경우, 폐쇄 위치로 십이지장을 고려해야 한다는 사실을 강조한다.

담도선섬유종은 매우 드문 담도상피성 종양으로서 양성 종양으로 분류된다. 그럼에도 불구하고, 담도선섬유종으로부터 악성 종양이 발생했다는 몇 개의 증례가 보고되어 왔다. 하지만 담도선섬유종과 그로부터 발생한 악성 신생물에 대한 영상의학적 소견은 잘 알려져 있지 않다. 우리는 담도선섬유종에서 발생한 담관암의 증례를 초음파, 컴퓨터단층촬영, 자기공명영상 사진과 함께 설명하고, 이와 감별할 질환들의 영상의학적 소견을 고찰하고자 한다.

Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups. (p<0.05) 5.The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, forteen (36.9%) were located at the posterior attachment and one (2.6%) was at the meniscus itself.

Pelioid hepatocellular carcinoma(HCC), a type of atypical HCC, is a rare histologic type of HCC. The radiologic findings of the pelioid HCC is differ from the typical type of HCC. To our knowledge, this case report is the second literature to show the enhancing features of a pelioid HCC on dynamic computed tomography (CT).Here we describe the dynamic CT findings in a case of surgically confirmed pelioid HCC.

The purpose of this article is to review imaging findings and to discuss the optimal imaging methods for craniosynostosis. The discussion of imaging findings are focused on ultrasonography, plain radiography, magnetic resonance imaging and computed tomography with 3-dimensional reconstruction. We suggest a strategy for imaging work-up for the diagnosis, treatment planning and follow-up to minimize or avoid ionized radiation exposure to children by reviewing the current literature.

The authors report 2 cases of nerve root herniation after discectomy of a large lumbar disc herniation caused by an unrecognized dural tear. Patients complained of the abrupt onset of radiating pain after lumbar discectomy. Magnetic resonance imaging showed cerebrospinal fluid signal in the disc space and nerve root displacement into the disc space. Symptoms improved after the herniated nerve root was repositioned. Clinical symptoms and suggestive radiologic image findings are important for early diagnosis and treatment.

In closed calcaneus fractures, the occurrence of FHL interposition in subtalar joint is relatively rare and difficult to diagnosis preoperatively. But careful physical examination and significant radiologic findings could be useful tools to diagnosis preoperatively. This findings is shearing off a superior medial fragment made up of the sustentaculum talus connected to a significant portion of the medial wall and medial aticular surface of the posterior facet.

Hepatic toxocariasis is a type of visceral larva migrans caused by the migration of second-stage larvae of certain nematodes such as Toxocara canis to the liver. Histologically, the condition is characterized by granulomatous lesions containing eosinophils and inflammatory cells. We report a case of hepatic toxocariasis with atypical clinical and radiologic findings presenting as distinct, solitary hepatic nodule detected in a middle-aged woman.
