Intra-individual comparison of liver stiffness measurements by magnetic resonance elastography and two-dimensional shear-wave elastography in 888 patients.

Purpose: Quantitative elastography methods, such as ultrasound two-dimensional shear-wave elastography (2D-SWE) and magnetic resonance elastography (MRE), are used to diagnose liver fibrosis. The present study compared liver stiffness determined by 2D-SWE and MRE within individuals and analyzed the degree of agreement between the two techniques.

Methods: In total, 888 patients who underwent 2D-SWE and MRE were analyzed.

Refugia in glacial ages led to the current discontinuous distribution patterns of the dark red-backed vole Myodes rex on Hokkaido, Japan.

The terrestrial mammalian fauna of the North Japanese island, Hokkaido, is more similar to that of Southern Siberia than to the main island of Japan, Honshu. Three species of the genus Myodes (Muridae, Rodentia) are found on Hokkaido, but not on Honshu. While Myodes rufocanus and M.

Osteological and genetic analysis of the extinct Ezo wolf (Canis lupus hattai) from Hokkaido Island, Japan.

The Ezo wolf (Canis lupus hattai Kishida, 1931 ) is an extinct subspecies that inhabited Hokkaido in Japan until the middle of the Meiji Period. Because there are very few preserved skeletons, no osteological and/or genetic analyses of the Ezo wolf have been conducted. In this study, 20 cranial and eight mandibular characters were measured on Ezo wolf skeletons, and mitochondrial DNA (mtDNA) was analyzed to assess genetic relationships between the Ezo wolf and other wolf lineages, including the Japanese wolf on Honshu.

Evaluation of pathological features of hepatocellular carcinoma by contrast-enhanced ultrasonography: comparison with pathology on resected specimen.

Features of hepatocellular carcinoma (HCC) observed by contrast-enhanced ultrasonography (CEUS) were compared to pathological features of corresponding resected HCC specimens, to evaluate the ability of CEUS to depict the pathological features of HCC. We investigated 50 HCC nodules that were treated by surgical resection. All nodules had been examined by CEUS with intravenous contrast agent (Levovist) before surgery.

Comparison of IV contrast-enhanced sonography and histopathology of pancreatic cancer.

Objective: We compared contrast-enhanced sonography findings with pathologic findings in pancreatic cancer to evaluate the ability of contrast-enhanced sonography to depict the pathologic changes associated with pancreatic cancer.

Subjects And Methods: Thirty-four patients with pancreatic cancer who underwent surgery were investigated. Sonography was performed with contrast material (Levovist) for all patients before surgery.

Clinical utility of doppler ultrasonography in evaluation of early therapeutic efficacy after transcatheter arterial embolization in patients with hepatocellular carcinoma.

This study was undertaken to determine the value of Doppler ultrasonography in the early evaluation of therapeutic efficacy of hepatocellular carcinoma after transcatheter arterial embolization (TAE). Fifty-two nodules in which tumor vascularity had been detected by Doppler ultrasonography before TAE were examined in 41 patients. Doppler signals were evaluated 1 week after TAE, and the results were compared with tumor vascularity as determined by dynamic magnetic resonance imaging (dynamic MRI), which was used as the gold standard.
