To observe the necessity and usefulness of follow-up Magnetic Resonance Imaging (MRI) and Computed Tomography Imaging (CTI) after RFA of osteoid osteoma.
A descriptive study.
Department of Radiology, Sisli Etfal Training and Research Hospital, Istanbul, Turkey, between May 2015 and January 2020.
Patients, who underwent CT-guided RFA for osteoid osteoma treatment, were followed-up both clinically and radiologically. MRI was recommended between the third and sixth months and CTI at 12th month or later for follow-up. All the pre and post-treatment radiological images were evaluated retrospectively. Radiological recovery was noted in three categories as complete/almost-complete, partial, and minimal-no recovery according to the healing of pre-treatment radiological findings.
One-hundred and thirty-one patients with at least one follow-up CT or MRI were included. All had technically and clinically successful RFA treatments. Of 131 patients, 64.1% had CTI and 82.4% had MRI follow-up. In follow-up images, complete/almost-complete-recovery was observed in 70.2%, partial recovery in 26.7%, and minimal recovery in 3.1% of the cases. Re-ablation therapies were applied in 2 cases in this study due to pain recurrence after three months of successful treatments.
Radiological follow-up is beneficial for the evaluation of outcome after RFA of osteoid-osteoma. At least one follow-up MRI may be helpful for the assessment of healing or recurrence. Follow-up CTI may not be needed unless planning a re-ablation.

观察骨样骨瘤 RFA 后行磁共振成像（MRI）和计算机断层成像（CTI）随访的必要性和实用性。
描述性研究。
土耳其伊斯坦布尔 Sisli Etfal 培训与研究医院放射科，2015 年 5 月至 2020 年 1 月。
对接受 CT 引导 RFA 治疗骨样骨瘤的患者进行临床和放射学随访。建议在第 3 至 6 个月行 MRI 检查，第 12 个月或之后行 CTI 检查以进行随访。所有治疗前后的影像学图像均进行回顾性评估。根据术前影像学表现的愈合情况，将影像学恢复分为完全/几乎完全、部分和微小/无恢复三种类型。
共纳入 131 例至少有一次 CT 或 MRI 随访的患者。所有患者的 RFA 治疗均获得技术和临床成功。131 例患者中，64.1%行 CTI 检查，82.4%行 MRI 随访。在随访图像中，70.2%的患者完全/几乎完全恢复，26.7%的患者部分恢复，3.1%的患者微小恢复。在这项研究中，由于成功治疗后 3 个月疼痛复发，有 2 例患者接受了再次消融治疗。
影像学随访有助于评估骨样骨瘤 RFA 后的治疗效果。至少进行一次 MRI 随访有助于评估愈合或复发情况。除非计划再次消融，否则无需进行 CTI 随访。
