PURPOSE To evaluate the non-Gaussian water diffusion properties of prostate cancer (PCa) and determine the diagnostic performance of diffusion kurtosis (DK) imaging for distinguishing PCa from benign tissues within the peripheral zone (PZ), and assessing tumor lesions with different Gleason scores. MATERIALS AND METHODS Nineteen patients who underwent(More)
OBJECTIVE The objective of this study was to investigate the non-Gaussian water diffusion properties in bladder cancer and assess the efficacy of diffusion kurtosis imaging for estimating the histological grade of bladder cancer. METHODS Twenty-one patients with bladder cancer (high-grade, 12; low-grade, 9) and 17 negative controls who underwent(More)
Meningiomas are the most common primary nonneuroglial extra-axial neoplasms, which commonly present as spherical or oval masses with a dural attachment. Meningiomas without dural attachment are rare and, according to their locations, are classified into 5 varieties, including intraventricular, deep Sylvain fissure, pineal region, intraparenchymal, or(More)
Ginsenoside Rb1 (GRb1), which is one of the main ingredients derived from Panax ginseng, has been widely used to treat various gastrointestinal disorders. The present study aimed to determine whether GRb1 was able to prevent intestinal mucosal barrier damage in rats following peritoneal air exposure for 3 h. GRb1 (5, 10, and 20 mg/kg) was orally(More)
Motion and deformation are common in prostate diffusion-weighted magnetic resonance imaging (DWI) during acquisition. These misalignments lead to errors in estimating an apparent diffusion coefficient (ADC) map fitted with DWI. To address this problem, we propose an image registration algorithm to align the prostate DWI and improve ADC map. First, we apply(More)
BACKGROUND Members of the SIRT family are a highly conserved family of NAD+-dependent enzymes, many of which (SIRT1-7) play an important role in tumor formation. Recently, several studies have suggested that SIRT4 not only regulates glutamine metabolism, but also serves as a tumor suppressor. There are no studies have assessed its clinical significance in(More)
OBJECTIVE This study aims to analyze the impact of delayed treatment of foreign body aspiration (FBA) in children. MATERIALS AND METHODS In this study, we retrospectively reviewed 220 children who were diagnosed with FBA through rigid bronchoscopy from January 2010 to May 2016 in our hospital. The time elapsed between aspiration event and arrival at our(More)
