Cardiac MRI (cMRI) has been reported as a method for characterization of canine thoracic vasculature. However, to the authors\u2019 knowledge, no published studies describe evaluation of canine PDA through cMRI. Three dogs were selected for this exploratory study. Electrocardiogram gating and breath\u2010hold techniques were performed using a 3T MR scanner. Both black blood imaging and bright blood cine acquisitions were performed. Quantification of stroke volume (SV) and shunting volume were calculated using a stack of short\u2010axis cine images. Additional 4D (three\u2010spatial dimensions plus time)\u2010TRAK (time\u2010resolved MR angiography with keyhole) sequences were conducted in patient 2 to verify other vasculature abnormality. Black blood images clearly depicted the course of the ductus from the descending aorta to the pulmonary artery in all three dogs. Morphological evaluation of PDA classified patients 1 and 2 as Type 2a and patient 3 as Type 1. Patient 2 was confirmed to have a concurrent persistent left cranial vena cava. Left ventricular SV, right ventricular SV, and left\u2010to\u2010right SV ratio were 12.4 ml, 3.36 ml, and 3.704, respectively, in patient 1; 6.85 ml, 1.22 ml, and 5.60 in the patient 2; and 3.67 ml, 2.14 ml, and 1.702 in patient 3. Findings indicated that cMRI is a feasible method for characterizing the morphology of PDA and extracardiac vasculature anomalies in dogs.<\/jats:p>","DOI":"10.1111\/vru.12446","type":"journal-article","created":{"date-parts":[[2016,11,20]],"date-time":"2016-11-20T23:36:42Z","timestamp":1479685002000},"page":"62-75","source":"Crossref","is-referenced-by-count":9,"title":["CARDIAC
