This study evaluated the efficacy of the combination of imprint cytology and histology in tissue-core percutaneous biopsy under real-time computed tomography (CT) fluoroscopic guidance. Between October 2009 and June 2013, 156 percutaneous needle biopsies were performed in our institution. Those obtained by tissue-core biopsy underwent both imprint(More)
As a routine diagnostic approach to patients who present hematuria or abnormal findings in X-ray films such as intravenous pyelograms, the cases are submitted to serial scintiphotography every two minutes after the intravenous administration of 250 μCi of131I-Hippuran and to renography with PHO/GAMMA Scintillation Camera (Nuclear-Chicago).

AIM The hepatic microenvironment, which may include chronic inflammation and fibrosis, is considered to contribute to the pathogenesis of liver metastases of colorectal cancer. A similar mechanism is anticipated for pulmonary metastases, although no reports are available. Smoking causes pulmonary inflammation and fibrosis. Thus, we hypothesized that smokers(More)
