Accurate
assessment of right ventricular (RV) function is clinically important
particularly in patients with pulmonary hypertension (PHTN). Compared to the left ventricle (LV), however, analysis
of RV function is relatively difficult because of relatively thin walls and
lack of geometric symmetry. Also in
PHTN, higher systolic blood pressure in the RV can cause excursion of the
interventricular septum into the LV
cavity causing it to lose its geometric symmetry. This abstract presents a method for
reconstructing three-dimensional biventricular strain from tagged MRI in each
imaged time frame through mid-diastole.
This method is validated on normal volunteers and PHTN patients.
