3DQRS: a method to obtain reliable QRS complex detection within high field MRI using 12-lead electrocardiogram traces.

Gregory TS1, Schmidt EJ, Zhang SH, Ho Tse ZT.
Magnetic resonance in medicine : official journal of the Society of Magnetic Resonance in Medicine / Society of Magnetic Resonance in Medicine.Magn Reson Med.2014 Apr;71(4):1374-80. doi: 10.1002/mrm.25078. Epub 2014 Jan 22.
PURPOSE: To develop a technique that accurately detects the QRS complex in 1.5 Tesla (T), 3T, and 7T MRI scanners.METHODS: During early systole, blood is rapidly ejected into the aortic arch, traveling perpendicular to the MRI's main field, which produces a strong voltage (V(MHD)) that eclipses the

Experimental model of transthoracic, vascular-targeted, photodynamically induced myocardial infarction.

Chrastina A1, Pokreisz P, Schnitzer JE.
American journal of physiology. Heart and circulatory physiology.Am J Physiol Heart Circ Physiol.2014 Jan 15;306(2):H270-8. doi: 10.1152/ajpheart.00818.2012. Epub 2013 Nov 8.
We describe a novel model of myocardial infarction (MI) in rats induced by percutaneous transthoracic low-energy laser-targeted photodynamic irradiation. The procedure does not require thoracotomy and represents a minimally invasive alternative to existing surgical models. Target cardiac area to be

ECG-based gating in ultra high field cardiovascular magnetic resonance using an independent component analysis approach.

Krug JW1, Rose G, Clifford GD, Oster J.
Journal of cardiovascular magnetic resonance : official journal of the Society for Cardiovascular Magnetic Resonance.J Cardiovasc Magn Reson.2013 Nov 19;15:104. doi: 10.1186/1532-429X-15-104.
BACKGROUND: In Cardiovascular Magnetic Resonance (CMR), the synchronization of image acquisition with heart motion is performed in clinical practice by processing the electrocardiogram (ECG). The ECG-based synchronization is well established for MR scanners with magnetic fields up to 3 T. However, t
