Background cardiac transthyretin amyloidosis (attr) is an increasingly recognized cause of heart failure cardiac magnetic resonance (cmr), with late gadolinium enhancement (lge) and t1 mapping, is emerging as a reference standard for diagnosis and characterization of cardiac amyloidosis. Analysis of headache chronification with imaging, deep phenotyping, and proteomics the safety and scientific validity of this study is the responsibility of the study sponsor and investigators listing a study does not mean it has been evaluated by the us federal government. Tesla ascertained that an alternating current in a wire loop generated an alternating magnetic field which in turn induced an alternating current in a nearby secondary coil by attaching a load to the secondary coil, the induced ac current could be made to do useful work (for example, charge a battery. Objective to quantify the prevalence of incidental findings on magnetic resonance imaging (mri) of the brain design systematic review and meta-analysis of observational studies data sources ovid medline (1950 to may 2008), embase (1980 to may 2008), and bibliographies of relevant articles.
