yes


Ex Input:
Question: Does echocardiographic tissue deformation imaging quantify abnormal regional right ventricular function in arrhythmogenic right ventricular dysplasia/cardiomyopathy?
Answer: DTI and two-dimensional strain-derived parameters are superior to conventional echocardiographic parameters in identifying ARVD/C. This novel technique may have additional value in the diagnostic workup of patients with suspected ARVD/C.

Ex Output:

yes
