Abstract
- Purpose: There are two well-known indications for first-pass perfusion in the literature. First is the evaluation of myocardial ischemia, and the other is the evaluation of tumor vascularity. Our aim was to assess the value of a first-pass contrast bolus tracking sequence (FPCBTS) for cases unrelated to these pathologies.<br />Materials and Methods: A total of 35 patients (age range, 1 day to 66 years; mean age, 10.4±19.2 years; median age, 4.5 months) with suspected congenital (n=31) and acquired (n=4) heart and great vessel disease were included in the study. All the patients underwent cardiac magnetic resonance imaging (MRI) and FPCBTS, and 20 patients underwent contrast enhanced magnetic resonance angiography (CE-MRA). We used cardiac MRI and CEMRA for anatomic evaluation and FPCBTS for dynamic flow evaluation.<br />Results: Truncus arteriosus, double outlet right ventricle, tetralogy of Fallot, corrected transposition of great arteries, atrial and ventricular septal defect, aortic rupture, cardiac hydatid cyst, tricuspid atresia, anomalous pulmonary venous return, and interrupted aorta were detected using the technique described here. Septal defects in six patients and atrial aneurysm in two patients were excluded. The shunt gap and flow direction of the septal defects, a ruptured wall in a dissected aorta, a hydatid cyst, and the atrial relationship in two cases with paracardiac masses were diagnosed easily using this dynamic evaluation technique.<br />Conclusion: FPCBTS can be performed in addition to cardiac MRI and CEMRA to reveal flow dynamics and morphology.
