Primary heart angiosarcoma detected by magnetic resonance imaging
Acta Radiologica, 2006We present a case of primary heart angiosarcoma in a 38-year-old male. The patient presented with severe dyspnoe and arrhythmia. Echocardiography showed multiple solid masses in the pericardium and pericardial effusion. Chest radiography revealed left-sided pleural effusion and suspicion of a mass projected on the right atrium.

Magnetic resonance imaging of primary pediatric liver tumors
Pediatric Radiology, 2016Although primary hepatic neoplasms are less common than other intra-abdominal tumors in children, these neoplasms are a significant source of morbidity and mortality in the pediatric population. MRI is increasingly relied upon in the diagnostic evaluation of these lesions, both before and after treatment, and familiarity with the MRI findings ...

Primary Resonance of Electrostatically Actuated Cantilever Resonators: Uniform vs. Nonuniform
Volume 5: Dynamics, Vibration, and ControlAbstract This work investigates the amplitude-frequency and amplitude-voltage responses of electrostatically actuated uniform and nonuniform micro-electro-mechanical systems (MEMS) cantilevers. A comparison between uniform and nonuniform cantilevers’ responses is conducted.
