Identification of non-responders early for the duration of CRT may perhaps spare numerous sufferers from a futile comprehensive therapy. Many results in HNSCC studies recommend that changes in ADC measured with an EPI-DWI method early during CRT are connected with locoregional response (11-13). Having said that, EPI-DWI suffers from geometrical distortions, especially in regions with air-tissue transitions which include inside the head and neck location. Consequently, the use of EPI-DWI in radiotherapy arranging and in simultaneous PETMRI Page 1 imaging may be limited. In this pilot study, we wanted to explore the usage of a non-EPI DWI process, for the reason that such DWI sequences are much more robust concerning geometricAME Publishing Firm.

We compared EPI-DWI with HASTE-DWI early during CRT for their potential to predict locoregional outcome. Our preliminary final results recommend that EPI-DWI appears to have greater potential in predicting locoregional outcome early after start of CRT than HASTE-DWI. While HASTE-DWI includes a decrease incidence of geometric distortions as in comparison to an EPI-DWI (15), this strategy appears to fail in early CRT response prediction in HNSCC. CRT induces loss of tumor cells and thus increases water mobility at the microscopic level. Response.
