“…OO treatment strategies have changed over the years, and image-guided local ablative procedures are now the method of choice (14,25). Besides cryoablation, hyperthermal techniques such as RFA, LA and MWA allow precise tumor ablation with high success rates while being less invasive and having fewer complications than open surgery (6,10,13,14,26,27).…”

“…Although there are cost disadvantages compared with LA (21), RFA is commonly used (14). CT is still the most common imaging modality for puncture guidance in minimally invasive OO treatment (28), but MRI guidance has also proven to be feasible in open or wide-bore MRI scanners, providing adequate patient access as well as highquality imaging for lesion localization and instrument guidance (7).…”

“…MRI guidance therefore might be a possible alternative as suggested by experience from MRIguided HIFU (33,34). Compared with MRI-guided HIFU, MRI-guided percutaneous LA has the advantage of shorter treatment duration (14,33). On the other hand, HIFU is an entirely noninvasive method (34).…”

“…With regard to nonsurgical focal therapies for OOs, several options exist. Mainly due to its wide availability and familiarity, CT-guided radiofrequency ablation (RFA) has become the treatment of choice with very good success rates, few complications, and high patient satisfaction in several clinical studies (6,(10)(11)(12)(13)(14)(15). However, as an alternative for image guidance, MRI offers potential advantages, such as better visualization of structures at risk and real-time temperature monitoring during thermal procedures (16,17).…”

“…Little data is available on MRI guidance and the potential of MRI thermometry during LA in the treatment of OO (7,22,23). In addition, most studies have been conducted with relatively short followup periods (14). The aim of the present study was to fill this gap and to investigate MRI-guided LA of OO in terms of treatment outcome, complications, and patient satisfaction at short-term and long-term follow-up.…”

Background: Aim of this study was to investigate short-term and long-term treatment outcome, complication rates, and patient satisfaction after MRI-guided laser ablation (LA) of osteoid osteoma (OO).Methods: Thirty-five patients with OO in typical and atypical localizations were treated by MRI-guided LA with MRI thermometry in an open 1.0 T system. Twenty-nine patients underwent a standardized telephone interview including questions about recurrence, residual pain or functional symptoms, and satisfaction for short-term follow-up after a mean of 31 months. Twenty-one of these patients were available for long-term telephone follow-up after a mean of 116 months.Results: Technical success of MRI-guided LA was 100% without major complications. Two minor complications included transient local inflammation and transient damage of the peroneal nerve associated with improper patient positioning during the procedure. Primary clinical success was 92% (11/12) in typically located OO and 82% (14/17) in atypically located OO. Secondary clinical success after repeat ablation was 100% regardless of OO location. Patient satisfaction and acceptance of the intervention were very good at both short-term (97%) and long-term (100%) follow-up.Conclusions: MRI-guided LA of OO is a safe and effective treatment option resulting in high short-term and long-term patient satisfaction and acceptance rates. Recurrence and adverse events were more common in patients with atypically located OO. Level of Evidence: Level 3, non-randomized follow-up study.
