Real-time elastography is a method for visualization of the elastic properties of soft tissue and may potentially enable differentiation between malignant and benign pathologic lesions. Our aim was to validate the method on a tissue-mimicking (TM) phantom and to evaluate the influence of different scanning parameters and investigator variability. A(More)
BACKGROUND & AIMS This study investigated if long-term treatment with high-dose mesalamine reduces the risk of clinical relapse of Crohn's disease after surgical resection. METHODS In a prospective, randomized, double-blind, multicenter study, 4 g of mesalamine (Pentasa; Ferring A/S, Vanlose, Denmark) daily was compared with placebo in 318 patients.(More)
PURPOSE To investigate whether ultrasound-based strain imaging can discriminate between colorectal adenocarcinomas and stenotic Crohn's lesions in newly resected surgical specimens. MATERIALS AND METHODS Resected surgical specimens from 27 patients electively operated for colorectal tumors or stenotic lesions from Crohn's disease were prospectively(More)
BACKGROUND Endoscopic ultrasonography is a precise method for TN staging of esophageal cancer. We explored the staging properties of a linear miniprobe as compared with a radial-scanning echoendoscope. METHODS Sixty-eight patients with esophageal cancer underwent preoperative TN staging using a 20-MHz linear miniprobe and a 7.5/12-MHz radial-scanning(More)
The gastrointestinal (GI) tract, with its layered structure, can be imaged by ultrasound using a transabdominal approach or intraluminal high-frequency probes. New ultrasound technology can be used to characterize tissue hardness, study motility in real-time, direct diagnostic and therapeutic intervention, evaluate GI wall perfusion and tissue viability,(More)
BACKGROUND Endoscopic ultrasonography (EUS) is generally accepted as a sensitive method for the detection of small pancreatic tumors. We report our experience with EUS for preoperative imaging of insulinomas. METHODS Nine patients with clinical and biochemical signs of insulinoma were examined by EUS using a 7.5/12 MHz radial-scanning ultrasound endoscope(More)
Endosonography is a useful tool for studying the morphology and motor function of the gastrointestinal tract. Intraluminal ultrasonography is the common denomination of ultrasound examinations using intracorporal transducers which are inserted into the GI tract. Thus, the visceral wall and adjacent structures can be imaged in detail. This review describes(More)
Endoluminal ultrasonography allows detailed imaging of the gastrointestinal wall and adjacent structures. Three-dimensional (3D) imaging may improve visualisation of topographic relations and the nature of pathologic lesions. The objective of this report is to summarise current status of 3D-endosonography and to discuss the possible clinical impact of this(More)
OBJECTIVES. The aim of this study was to evaluate the diagnostic potential of strain assessment in solid focal pancreatic lesions using real-time elastography in combination with endoscopic ultrasonography (EUS). MATERIAL AND METHODS. Forty-eight solid focal pancreatic lesions in 39 patients were included prospectively over a 3-year period and studied by(More)
BACKGROUND Lansoprazole is a potent antisecretory drug also possessing anti-Helicobacter pylori activity in vitro. It is a candidate drug for combination regimens with antibiotics for treating H. pylori infections. METHODS In a semiblind study, 65 patients with duodenal and/or gastric ulcer and pathologic 14C urea breath test results were treated with(More)
