BACKGROUND We aimed to assess the feasibility of 3 dimensional (3D) respiratory and ECG gated, gadolinium enhanced magnetic resonance angiography (MRA) on a 3 Tesla (3 T) scanner for imaging pulmonary veins (PV) and left atrium (LA). The impact of heart rate (HR) and rhythm irregularity associated with atrial fibrillation (AF) on image and segmentation(More)
A nthracyclines are potent antineoplastic agents with proven efficacy in the treatment of many pediatric and adult hematologic and solid organ cancers. Dose-dependent anthracycline-induced cardiomyopathy is the most notorious and well-studied chemotherapy-induced cardiovascular toxicity that was first described in 1971 in 67 patients treated with Adriamycin(More)
The transition from healthy myocardium to hypertensive heart disease is characterized by a series of poorly understood changes in myocardial tissue microstructure. Incremental alterations in the orientation and integrity of myocardial fibers can be assessed using advanced ultrasonic image analysis. We used a modified algorithm to investigate left(More)
