Video from ECR 2019: Hugh Harvey on validation of AI

Mar 2, 2019

Clinical validation of artificial intelligence (AI) is still a long way off, admits Dr. Hugh Harvey, who moderated the Artificial Intelligence Exhibition (AIX) at ECR 2019 with Dr. Wim Van Hecke, CEO of icometrix in Leuven, Belgium. In this interview, Harvey, clinical director at Kheiron Medical, reflects on the future development of AI and the unresolved issues that need to be addressed.

Representative MRI scans for which the independently assigned imaging-derived extranodal extension (iENE) grades differed among the readers. (A) Axial and sagittal images in a 56-year-old male patient with nasopharyngeal carcinoma and cervical nodal metastases. Readers 1 and 3 interpreted the finding as a metastatic lymph node invading the left sternocleidomastoid muscle (arrow) and assessed an iENE grade of 3, whereas reader 2 assigned a grade of 2. After joint review, the radiologists reached a consensus on the absence of definite sternocleidomastoid muscle invasion, and the final iENE grade was 2. (B) Axial and sagittal images in a 52-year-old male patient with nasopharyngeal carcinoma and cervical nodal metastases. Reader 1 interpreted the findings as a single enlarged metastatic lymph node and assessed an iENE grade of 1, whereas readers 2 and 3 interpreted them as two coalescent metastatic lymph nodes (arrows) and assessed a grade of 2. After joint review, the radiologists reached a consensus on the coalescence of the two metastatic lymph nodes, and the final iENE grade was 2.
