목적: 호흡정지 간 자기공영상에서 국소 간 병변을 발견함에 있어 동위상(inphase) 방식과 역위상(opposed-phase) 방식의 fast multiplanar spoiled gradient recalled(FMPSPGR) 영상간의 효율성을 비교하고자 하였다. 대상 및 방법: 다른 검사를 통해 국소 간 병변이 발견되었거나 의심되었던 45명의 환자의 78개의 병변에 대한 고속경사에코대열의 동위상과 역위상 영상을 비교하였다. 병변 발견률을 평가하기 위해 세 명의 사전 정보 없는 판독의가 독립적으로 영상을 검토하였다. 간의 신호대잡음비, 병변과 간의 대조대잡음비 및 간과 비장 간 대조대잡음비를 비교하였다. 세 명의 동의에 의해 어느 대열에서 영상의 질이 더 나은지 결정하였다. 결과: 역위상 영상에서 판독의 1, 2, 3이 각각 61(78%), 61(78%), 및 63(89%)개의 병변을 정확히 발견하였다. 동위상 영상에서 각 판독의가 66(85%), 65(83%) 및 65(93%)개의 병변을 발견하였다. 두 영상을 조합하였을 때, 71(91%), 69(88%) 및 76(97%)개의 병변이 각각 발견되었다. 간세포암이 증례에서 간-병변간 대조대잡음비는 역위상 영상에서 더 컸으나(p<0.05), 다른 병변에서의 의미 있는 차이는 보이지 않았다. 간-비장간 대조잡음비는 역위상 영상에서 높았으나(p<0.1), 간의 신호대잡음비는 동위상 영상에서 더 높았다. 결론: 국소적 간 병변을 놓치지 않고 발견 하기 위새서는 동위상 영상과 역위상 영상을 모두 이용하는 것이 바람직하다.

This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in. Thirty-two of 33 (97%) lesions showed early positive enhancement in the arterial phase. Twenty-three of these exhibited isoechoic or hyperechoic features in the portal phase. HAML demonstrate characteristic manifestations with SonoVue-enhanced real-time gray-scale ultrasonography.

Objective: To investigate the efficacy of gadobenate dimeglumine (GdBOPTA) enhanced MR imaging for the detection of liver lesions in patients with primary malignant hepatic neoplasms. Materials and Methods: Thirty-one patients with histologically proven primary malignancy of the liver were evaluated before and after administration of GdBOPTA at dose 0.05 or 0.10 mmol/kg. T1-weighted spin echo (T1W-SE) and gradient echo (T1W-GRE) images were evaluated for lesion number, location, size and confidence by three off-site independent reviewers and the findings were compared to reference standard imaging (intraoperative ultrasound, computed tomography during arterial portography or lipiodol computed tomography). Results were analyzed for significance using a two-sided McNemar's test. Results: More lesions were identified on Gd-BOPTA enhanced images than on unenhanced images and there was no significant difference in lesion detection between either concentration. The largest benefit was in detection of lesions under 1 cm in size (7 to 21, 9 to 15, 16 to 18 for reviewers A, B, C respectively). In 68% of the patients with more than one lesion, Gd-BOPTA increased the number of lesions detected. Conclusion: Liver MR imaging after Gd-BOPTA increases the detection of liver lesions in patients with primary malignant hepatic neoplasm.

Hepatic coccidiosis was occurred in a rabbit farm in Chonbuk province. Clinically, rabbits showed anorexia, diarrhea, dehydration, and depression, subsequently died 3 - 5 days after onset of clinical signs. Grossly, multifocal white spots or lines on the liver suface were observed. Histopathologic lesions included hyperplasia of bile duct epithelium with infiltration of inflammatory cells such as plasma cells and granulocytes, which represents chronic pericholangitis. Different developmental stages of Eimeria stiedae were observed inside the epithelium of biliary system. This is the case of hepatic coccidiosis in rabbits.

Image findings of hepatic lymphoma have been reported as variable, ranging from single or multiple small nodules to diffuse infiltrative patterns. On MRI, most hepatic lymphomas show T1 low signal intensity, T2 high signal intensity. Dynamic imaging reveals a hypointense appearance in the arterial phase, followed by delayed enhancement in the portal venous and transitional phase. In the hepatobiliary phase using a hepatocyte-specific contrast agent (which have recently aided in increasing the access to the focal liver lesions), hepatic lymphoma is known to exhibit low signal intensity. We report a case of hepatic lymphoma, which shows iso-signal intensity on hepatobiliary phase, using gadoxetic acid (Gd-EOB-DTPA).

This study was performed to investigate the pathogenesis of hepatic granuloma and hepatic fibrosis induced in mice infected with Capillaria(C) hepatica and treated cyclophosphamide. The results were as grossly well-defined yellowish white spots and small nodules at the surface of the liver were scattered. Histopathologically, there were numerous granulomas composed of eggs and fragments of C hepatica surrounded by heavy infiltration of inflammatory cells. Severe fibrosis was observed around granulomas. Pathological lesions of group infected with C. hepatica and then injected with cyclophosphamide were most severe than those of other groups. Therefore this study suggested that hepatic fibrosis induced by C hepatica in mice would be useful for animal model of hepatic fibrosis in human.
