“…Vogl et al published a case report of a patient with a recurrent neuroendocrine metastasis in the breast treated with MRI‐guided LITT. The postinterventional MR control exams 1 day and 4 months after laser‐induced thermotherapy with the 1.5T MR unit verified the complete ablation of the tumor, without any signs of residual or relapsing tumor.…”

In the last decades, an increasing interest has developed towards non‐invasive breast lesion treatments, which offer advantages such as the lack of surgery‐related complications, better cosmetic outcomes, and less psychological distress. In addition, these treatments could be an option for patients with poor health who are not candidates for surgery. Non‐surgical ablation can be performed under magnetic resonance (MR) or ultrasound (US) guidance. US is cheaper and easily available, while contrast‐enhanced MR is more accurate, ensuring better safety and efficacy for the patient. Overall results of studies about MRI‐guided tumor ablation reported complete ablation rates ranging between 20% and 100%. High‐intensity focused ultrasound (HIFU or FUS) is the most studied ablative technique and it is already established as a valid technique for ablation of benign and malignant tumors in various organs. Ultrasound‐guided FUS is very useful for young patients who refuse surgery or with multiple nodules; however, MR‐guided FUS is more sensitive and allows a better evaluation of thermal accumulation within the ablated tissue or the adjacent structures. Most MR‐guided FUS studies used a dedicated high‐field MR scanner and complete tumor ablation was reported in 17–90% of cases. Other techniques using thermal tissue destruction are radiofrequency ablation (RFA) and laser interstitial thermal therapy (LITT). Only a few studies assessed the efficacy of these treatments, all were performed with open MR devices. RFA showed complete tumor ablation in 30–96% of patients, while LITT in 10–71%, but all the studies had a small number of patients. Cryoablation obtains tissue ablation by a rapid decrease of temperature, with a complete tumor removal reported in 18–52% of cases with MR guidance. No serious complications were reported with these techniques. Currently, breast conservative surgery replaced radical surgery when possible. Therefore, future research should focus on these treatments to shift towards an even less invasive approach to breast neoplasms. Level of Evidence: 5 Technical Efficacy: Stage 5 J. Magn. Reson.

Synopsis Contrast enhanced breast MRI is increasingly being used to diagnose breast cancer and to perform biopsy procedures. The American Cancer Society has advised women at high risk for breast cancer to have breast MRI screening as an adjunct to screening mammography. This article places special emphasis on biopsy and operative planning involving MRI and reviews utility of breast MRI in monitoring response to neoadjuvant chemotherapy. We describe peer-reviewed data on currently accepted MR-guided therapeutic methods for addressing benign and malignant breast diseases, including intraoperative imaging.

“…However, a limitation often encountered with interstitial therapies is unintentional charring at the surface of the diffusers [7]. In a Phase I clinical trial of 899 patients with a total of 2,520 lesions, it was found that MR-guided ILH with local anesthesia was safe, yielding acceptably low rates of major complications, however, the treatment at times required internally cooled diffusers [8]. The unintentional charring was partially attributed to hot spots in the fiber emission.…”

The longitudinal radiance emission is homogenous to within +/-10%. The ability to create custom designed longitudinal emission profiles was demonstrated. The variations of the polar and azimuth radiance emission diagrams were within +/- 15% from an ideal Lambertian emitter. The polar uniformity can be improved with a slight increase of the outer diameter using a diffusing recoating compound. The residual light leakage at the distal end of the fiber diffuser was suppressed to 2%. The minimal bending radius after recoating is approximately 5 mm. Maximum power distribution is > 0.5 W cm(-1).
