Thank you for your comment about our study [1]. We completely agree with the opinion. Although we had excluded cases with motion artifacts and blurring of right ventricular borders, we believe that absence of EKG gating could have played a role in the exaggeration of right ventricular wall thickness measurements. Nonetheless, performing EKG gating had not been feasible in our everyday practice in the setting of acute pulmonary embolism. However, as you correctly mentioned, with the advent of faster CT scanners with an improved temporal resolution, this problem may be resolved in the future.
