Electrocardiographs recorded in a magnetic field for cardiac-gating in magnetic resonance imaging (MRI) are complicated by blood flow-induced potentials. This study examines which lead of the standard 12-lead ECG maximizes the QRS while minimizing flow-induced interference. Twelve-lead ECGs were performed on normal volunteers (n = 9) and patients (n = 13)(More)
Digital subtraction angiography is an indispensable complement to cut film studies for the detection of pulmonary artery injury. Immediate transcatheter embolization of catheter-induced pulmonary artery pseudoaneurysm is a safe, minimally invasive, fast, and cost-effective alternative to surgical treatment.
The purpose of this study was to prospectively assess the feasibility and safety of early feeding in patients with newly placed one-step button (OSB) gastrostomy devices. Twenty-five patients who underwent percutaneous endoscopic button gastrostomy placement were prospectively enrolled. The patients underwent radiographic assessment (Gastrografin(More)
