EUS-Guided Biliary Drainage
The echoendoscopic biliary drainage is an option to treat obstructive jaundices when ERCP drainage fails. These procedures compose alternative methods to the side of surgery and percutaneous transhepatic biliary drainage, and it was only possible by the continuous development and improvement of echoendoscopes and accessories. The development of linear setorial array echoendoscopes in early 1990...
متن کاملSuperconducting open-configuration MR imaging system for image-guided therapy.
PURPOSE To develop a superconducting magnetic resonance (MR) imager that provides direct access to the patient and permits interactive MR-guided interventional procedures. MATERIALS AND METHODS A 0.5-T superconducting magnet that allows a region of vertical access to the patient was designed and constructed. This magnet was integrated with newly designed shielded gradient coils, flexible surf...
متن کاملEndoscopic Ultrasound-Guided Biliary Drainage
OBJECTIVE To demonstrate a comprehensive review of published articles regarding endoscopic ultrasound (EUS)-guided biliary drainage. MATERIALS AND METHODS Review of studies regarding EUS-guided biliary drainage including case reports, case series and previous reviews. RESULTS EUS-guided hepaticogastrostomy, coledochoduodenostomy and choledoantrostomy are advanced biliary and pancreatic endo...
متن کاملFunctional MR imaging on an open 1T MR imaging system: exploiting the advantages of an open MR imaging system for functional MR imaging.
BACKGROUND AND PURPOSE Open MR imaging scanners are designed for imaging of specific patient groups that cannot be routinely scanned with conventional MR imaging scanners (eg, patients with obesity and claustrophobia). This study aims to determine whether BOLD sensitivity on an open 1T scanner is adequate for fMRI for diagnostic and research purposes by directly comparing fMRI results with a st...
متن کاملInteractive Mr-guided Percutaneous Nephrostomy Using an Open 1t Mr-scanner: First Experience in 15 Patients
INTRODUCTION Usually percutaneous nephrostomy is performed under sonographic guidance in a fluoroscopy suite. Although MR provides detailed images of the upper urinary tract (1,2), there still exist only very preliminary results that have been reported about MR -guided percutaneous nephrostomy (3,4). When sonographic guidance is not possible due to e.g. severe obesity, overlying intestinal gas,...
