“…It has been reported that lesions >3 cm were not as effectively treated at the margins by RFA [23]. The incomplete ablation is largely attributed to the ‘heat sink' effect, a reduction in tissue temperature due to the conductive effects of adjacent vessels, typically described as ≥3 mm in diameter [24].…”

Background: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. Summary: This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques. Key Message: Advances in image-guided locoregional therapies, including local ablative therapy and transarterial therapy, have led to a major breakthrough in the management of HCC. Both survival rates and cure rates of patients with HCC have improved markedly since the introduction of these techniques. Practical Implications: Radiofrequency ablation is currently considered as an alternative to surgical resection for patients with early-stage HCC. A newer technique of ablation such as microwave ablation is increasingly being used, especially for large HCC. Transarterial chemoembolization has become a standard care for asymptomatic patients with multinodular tumors in intermediate-stage disease, and transarterial radioembolization has become the method of choice in HCC cases with portal vein thrombosis. Moreover, combination treatment modalities, such as thermal-based ablation combined with transarterial chemoembolization or ¹²⁵I seed implant brachytherapy, may further broaden their clinical indications for HCC. Moreover, use of localized radiation in combination with thermal ablation has been reported to improve tumor control and long-term survival.

“…The MRI has, however, unique properties that give it potential advantage when compared with CT in performing interventional procedures. The MRI has superior soft tissue resolution, even in interventional sequences; also bone interventions can be reliably conducted [24,25]. To reach bone tissue one must pass soft tissue structures that are often critical of nature (nerves, vessels).…”

“…Percutaneous interstitial laser treatment has been successfully applied to osteoid osteoma under CT guidance [15,16,17,18,19,20,21,22]. The MRI guidance has been successfully applied to percutaneous bone biopsies and interstitial laser treatment guidance and monitoring in soft tissue tumors [23,24,25,26,27,28,29,30]. The thermal monitoring capability of a low-field MRI scanner has also been reported [31].…”

MR imaging-guided laser ablation of osteoid osteomas with use of optical instrument guidance at 0.23�T

The purpose of this study was to determine the feasibility and features of low-field MR imaging in performing interstitial laser ablation of osteoid osteomas. Between September 2001 and April 2002, five consecutive patients with clinical and imaging findings suggesting osteoid osteoma and referred for removal of osteoid osteoma were treated with interstitial laser treatment. A low-field open-configuration MRI scanner (0.23 T, Outlook Proview, Philips Medical Systems, Finland) with optical instrument guidance hardware and software was used. Laser device used was of ND-Yag type (Fibertom medilas, Dornier Medizin Technik, Germany). A bare laser fiber (Dornier Medizin Technik, Germany) with a diameter of 400 microm was used. Completely balanced steady-state (CBASS; true fast imaging with steady precession) imaging was used for lesion localization, instrument guidance, and thermal monitoring. A 14-G (Cook Medical, USA) bone biopsy drill was used for initial approach. Laser treatment was conducted through the biopsy canal. All the lesions were successfully localized, targeted, and treated under MRI guidance. All the patients were symptom free 3 weeks and 3 months after the treatment. There was one recurrence reported during follow-up (6 months). The MRI-guided percutaneous interstitial laser ablation of osteoid osteomas seems to be a feasible treatment mode.

“…A lesion within the mediastinum, chest wall or even the lung may be well displayed, but MR imaging is still unable to document pneumothorax formation, which occurs in approximately 20-40% of all chest biopsies [54], so that CT remains the method to be favored for percutaneous chest procedures. MRguided musculoskeletal biopsies have been reported in low or midfield open systems [26, 60,61]. MR guidance is indicated also for the biopsy of bone marrow edema of unknown origin, since MRI allows a unique lesion dis- Fig.…”

Interventional and intraoperative MR: review and update of techniques and clinical experience

The concept of interventional magnetic resonance imaging (MRI) is based on the integration of diagnostic and therapeutic procedures, favored by the combination of the excellent morphological and functional imaging characteristics of MRI. The spectrum of MRI-assisted interventions ranges from biopsies and intraoperative guidance to thermal ablation modalities and vascular interventions. The most relevant recently published experimental and clinical results are discussed. In the future, interventional MRI is expected to play an important role in interventional radiology, minimal invasive therapy and guidance of surgical procedures. However, the associated high costs require a careful evaluation of its potentials in order to ensure cost-effective medical care.
