We read with great interest the article by Carraro do Nascimento et al describing the frequency of emboli on diffusion weighted imaging after transfemoral (TFA) and transradial approach (TRA).1 They have shown that TRA can show increased emboli compared with TFA, although performed by experienced operators as in their case. A few points are worth mentioning in this study.

The authors used a 5 French (5F) size catheter for their TRA cases and a 4F size catheter for their TFA cases. We believe this may cause some discrepancy as a 5F catheter can create greater friction …
