What is Three-dimensional quantitative margin assessment in patients with colorectal liver metastases treated with percutaneous thermal ablation using semi-automatic rigid MRI/CECT-CECT co-registration about?

## Purpose: To assess the quantitative minimal ablation margin (mam) in patients with colorectal liver metastases (crlm) treated with percutaneous thermal ablation (ta) and correlate the quantitative mam with local tumour recurrence (ltr). ## Method: Thirty-nine of 143 patients with solitary or multiple crlm who underwent a first percutaneous ta procedure between january 2011 and may 2020 were considered eligible for study enrolment. image fusion of pre- and post-ablation scans and 3d quantitative mam assessment was performed using the in-house developed semi-automatic rigid mri/cect-cect co-registration software delivered. the quantitative mam was analysed and correlated with ltr. ## Results: Eighteen (46 %) patients were additionally excluded from further analyses due to suboptimal co-registration (quality co-registration score ≤ 3). the quality of co-registration was considered sufficient in 21 (54 %) patients with a total of 29 crlm. ltr was found in 5 of 29 (17 %) ta-treated crlm. in total, 12 (41 %) negative mams were measured (mean mam -4.7 ± 2.7 mm). negative mams were significantly more frequently seen in patients who developed ltr (100 %) compared to those without ltr (29
