OBJECTIVES The objective of this study was to evaluate the diagnostic benefit of an intravoxel incoherent motion (IVIM) model-based characterization of pancreatic masses from diffusion-weighted imaging (DWI) with 3 b values. MATERIALS AND METHODS This retrospective study had an approval from the institutional review board, and informed patient consent was(More)
PURPOSE The aim of this study was to evaluate an intravoxel incoherent motion (IVIM) model-based analysis of diffusion-weighted imaging (DWI) for assessing the response of hepatocellular carcinoma (HCC) to locoregional therapy. PATIENTS AND METHODS Respiratory-gated DWI (b=0, 50, and 800 s/mm2) was retrospectively analyzed in 25 patients who underwent(More)
BACKGROUND AND STUDY AIMS Colorectal cancer (CRC) is one of the most common cancers worldwide, and several efforts have been made to reduce its occurrence or severity. Although colonoscopy is considered the gold standard in CRC prevention, it has its disadvantages: missed lesions, bleeding, and perforation. Furthermore, a high number of patients undergo(More)
Keratins 8 and 18 (K8 and K18) are the cytoskeletal intermediate filament proteins of adult hepatocytes. Murine models indicate that mutations in the K8- and K18-encoding genes predispose to liver injury. Moreover, studies showed an association of K8/K18 variants with human acute and chronic liver diseases. However, only little is known about a putative(More)
OBJECTIVE To investigate whether the occurrence or clearance of microhemorrhages in cerebral amyloid angiopathy (CAA)-related vascular inflammation can be modified by immunosuppressive treatment. METHODS Clinical and radiologic follow-up for more than 5 years of a patient with histopathologically confirmed CAA-related vascular inflammation treated with a(More)
