PURPOSE To investigate the value of 64-detector row CT first-pass perfusion imaging in the evaluation of tumor perfusion in patients with lung carcinoma, and to assess the correlation between the perfusion parameters and tumor angiogenesis. MATERIALS AND METHODS Forty-six surgically peripheral lung carcinomas were examined with 64-detector row CT.(More)
AIM To determine whether an increased dosage of esomeprazole 40 mg twice daily in triple therapy improved the Helicobacter pylori eradication rate for patients with different genotypes of S-mephenytoin 4'-hydroxylase (CYP2C19). METHODS Two hundred H. pylori-infected dyspeptic patients were randomized to receive clarithromycin 500 mg twice daily and(More)
AIM To measure the common bile duct (CBD) diameter by magnetic resonance cholangiopancreatography (MRCP) in a large asymptomatic population and analyze its some affecting factors. METHODS This study included 862 asymptomatic subjects who underwent MRCP. The CBD diameter was measured at its widest visible portion on regular end-expiration MRCP for all(More)
AIM To prospectively assess the feasibility of a whole-tumour perfusion technique using 64-detector row computed tomography (CT) and to analyse the variation of CT perfusion parameters in different histological types, sizes, and metastases in patients with peripheral lung carcinoma. METHODS AND MATERIALS Ninety-seven pathologically proved peripheral lung(More)
Perfusion CT has been applied in many clinical areas, but few studies have addressed gastric cancer. This study is to investigate the feasibility of first-pass perfusion CT with volume-based technique to assess microcirculation of gastric adenocarcinoma. Perfusion CT of gastric adenocarcinoma was performed with 64-section MDCT in 58 patients, which were(More)

To investigate features of crush extremity fractures associated with massive earthquake on digital radiography (DR) and multidetector computed tomography (MDCT). Six hundred and twenty-three consecutive patients with clinically confirmed crush extremity fractures arising from the 2008 Sichuan earthquake were enrolled into our study. Six hundred and eleven(More)
Perfusion CT is an attractive technique to assess tumor vascularity, and no studies have addressed the relationship between CT perfusion imaging and gastric tumor angiogenesis with volume-based technique. This study aims to assess the correlation between perfusion CT parameters using a volume-based technique and immunohistochemical markers of angiogenesis(More)
A 4.5-month-old Chinese boy presented with a bulging mass in the anterior right maxillary region. Clinical features and incisional biopsy examination confirmed the diagnosis of melanotic neuroectodermal tumour of infancy (MNTI). The lesion had first been noted a month before the biopsy. The extent of the lesion was defined via computed tomography, and(More)
The purpose of this study was to determine the usefulness of first-pass whole nodule perfusion imaging in the differentiation of benign and malignant solitary pulmonary nodules (SPNs). 77 patients with non-calcified SPNs (46 malignant, 22 benign and 9 active inflammatory) underwent first-pass perfusion imaging with a 64-detector row CT scanner. Perfusion,(More)
