Given the importance of Modic change identification for basivertebral nerve ablation (BVNA) candidacy, interrater reliability for this specific cohort has not yet been reported. Twenty lumbar magnetic resonance images of potential basivertebral nerve candidates were independently reviewed by two neuroradiologists and two interventional spine physiatrists for the presence and characterization of Modic changes. The kappa value of their agreement on the presence of Modic changes was 0.52 (95% confidence interval [CI] 0.37\u20130.67), whereas agreement on the type of Modic change was 0.51 (95% CI 0.37\u20130.65). Using an alternative methodology for measuring interrater reliability (Gwet's AC1) yielded the identification of the presence of Modic changes at AC1 0.51 (95% CI 0.36\u20130.66), whereas agreement on the type of Modic change was AC1 0.75 (95% CI 0.66\u20130.83). While less common, AC1 may be preferred in the appropriate cohort to kappa as it mitigates some of the pitfalls to which kappa values may be victim. Ultimately, our results are in\u2010line with previous reports of interrater reliability results for Modic changes in other cohorts and should serve to caution those who perform BVNA regarding interrater agreement of the imaging crux of the procedure.<\/jats:p>","DOI":"10.1002\/jor.25449","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T08:41:26Z","timestamp":1665045686000},"page":"1123-1130","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The interrater reliability of Modic changes among a potential basivertebral nerve ablation population: Why AC1 may be preferred to kappa"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4324-6241","authenticated-orcid":false,"given":"David","family":"Sherwood","sequence":"first","affiliation":[{"name":"Department of Orthopedics University Health Lakewood Medical Center Kansas City Missouri USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard Sterling","family":"Haring","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derek","family":"Schirmer","sequence":"additional","affiliation":[{"name":"Stanford University Medical Center Physical Medicine and Rehabilitation Division Redwood City California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Modic","sequence":"additional","affiliation":[{"name":"Department of Radiology Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,10,18]]},"reference":[{"issue":"2","key":"e_1_2_12_2_1","first-page":"1","article-title":"A definition and clinical grading of Modic changes","volume":"40","author":"Udby PM","year":"2021","journal-title":"J Orthopeadic Res"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.166.1.3336678"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.149.3.531"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-016-4459-7"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-008-0770-2"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0200677"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0114993"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-012-2309-9"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2012.03.026"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A0925"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A4498"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-020-06378-8"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2503080474"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000003495"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-006-0185-x"},{"issue":"2","key":"e_1_2_12_17_1","article-title":"The interrater reliability of the novel Udby classification of Modic Changes: a first estimate","volume":"1","author":"Sherwood D","year":"2022","journal-title":"Interv Pain Med"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-018-5496-1"},{"key":"e_1_2_12_19_1","unstructured":"Relievant Medsystems\u00a0Inc.
