An implanted pacemaker is generally considered a contraindication for magnetic resonance imaging (MRI). The increasing number of indications for MRI and the rising prevalence of implanted cardiac pacemakers have prompted the recent development of MRI-conditional pacemaker systems. We present the case of a 68-year-old woman with left ventricular hypertrophy, hypertension, aortic valve stenosis a...
brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...
Background The Electrocardiogram (ECG) is a standard clinical tool for cardiac physiological monitoring, required for cardiac synchronization during cardiac MRI, despite signal artifacts resulting from Magnetohydrodynamic voltages (VMHD). VMHD becomes significant during systole when rapidly ejected blood from the left ventricle into the aortic arch interacts with the strong magnetic field (B0) ...
The purpose of this article is to provide a current review of the spectrum of multidetector CT (MDCT) and MRI findings for a variety of cardiac neoplasms. In the diagnosis of cardiac tumors, the use of MDCT and MRI can help differentiate benign from malignant masses. Especially, the use of MDCT is advantageous in providing anatomical information and MRI is useful for tissue characterization of ...
Cardiac magnetic resonance imaging (MRI) is an important tool that makes it possible to evaluate patients with cardiovascular disease; in addition to infarction and alterations in myocardial perfusion, cardiac MRI is useful for evaluating other phenomena such as microvascular obstruction and ischemia. The main prognostic factors in cardiac MRI are ventricular dysfunction, necrosis in late enhan...
Background and Objectives: Iran is a large country that is often an importer of major medical equipment. There is no comprehensive databank of the status of the equipment in the country. The present study provides a clear description of the dispersal status of major medical equipment in the country in 2016 and the estimated number of required devices in 2026. Methods: This study was conduct...
To evaluate the frequency and clinical features of heart involvement in Fabry disease (FD) diagnostic value cardiac MRI speckle-tracking echocardiography.
Background—Cardiac dysfunction is associated with neuroanatomic and neuropsychological changes in aging adults with prevalent cardiovascular disease, theoretically because systemic hypoperfusion disrupts cerebral perfusion, contributing to subclinical brain injury. We hypothesized that cardiac function, as measured by cardiac index, would be associated with preclinical brain magnetic resonance ...

Background Performing MRI-guided interventions, such as for the treatment of ventricular tachycardia, requires the ability to rapidly detect and treat acute cardiac conditions, should they occur in the MRI. We developed MRI-compatible 12lead ECG systems, and demonstrated detection of acute ischemia during imaging [Tse, MRM. ‘13,Zhang, MRM. ‘15 ], providing a tool to non-invasively detect cardia...
