Abstract
To determine the ability of cine magnetic resonance imaging (MRI) to assess left ventricular (LV) volumes, we studied 20 children (age 4 months to 10 years) with various heart disease, validated by comparison with biplane LV angiography. Previous MRI studies to assess LV volumes have used multiple axial planes, which are compromised by partial volume effects and are time consuming to acquire and analyze. Accordingly, an imaging approach using biplane cine MRI and planes aligned with the true cardiac axes (the intrinsic long and short axis) of the LV was developed in views comparable with biplane LV angiography. In all patients, LV volumes were calculated by a Simpson's rule algorithm, both in MRI and LV angiography. MRI determined LV volumes were slightly underestimated but correlated reasonably well with angiographic values (LVEDV: Y=0.88X + 1.58, R=0.98, LVESV: Y=0.72X + 1.02, R=0.98). Especially, even in the patients who have abnormal left ventricular geometry such as Tetralogy of Fallot, MRI determined LV volumes correlated well with angiographic values. It is concluded that biplane cine MRI, using the intrinsic LV long and short axis planes, permits noninvasive assessment of LV volumes in views comparable to standard angiographic projections and appears practical for clinical use
