“…The unique ability of the MRI is the capability of monitoring thermal changes in tissue. This is not possible to the same extent with CT or ultrasound, as only MRI can provide quantitative information about thermal changes in tissue [35,36,37,38,39]. Generally, high-field devices are more suitable for thermal monitoring because of better signalto-noise ratio; however, the high-field devices lack the patient access that open scanners possess.…”

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.

“…Other therapeutic options include intra-lesion injection of various substances, either with curative intent (e. g. sclerosing agents) or to facilitate subsequent surgical removal [14][15][16][17][18][19], temperature mapping of magnetic resonance-guided laser interstitial thermal therapy [20], and radiofrequency-induced thermotherapy [21]. However, these techniques presuppose the correct preoperative diagnosis, which is usually not the case in cystic lymphangiomas in adults.…”

Lymphangiomas are uncommon lesions of lymphatic channels that are often present at birth and diagnosed mostly (90%) before the age of two years. Lymphangiomas occur exceedingly rarely in adults and few cases are described in the literature. The treatment of choice is complete surgical removal; however, the tumor tends to spread along vital structures therefore sometimes inductive complete surgical removal is impossible. We describe the clinical and pathological features of cystic lymphangioma diagnosed in three adults with lateral neck mass. Clinical examination, ultrasonography, MRI and fine-needle aspiration cytology were performed. We discuss the diagnostic difficulties of this uncommon lesion where in many cases the correct diagnosis is reached only after histopathological investigation of the surgical specimen. Therapeutic options are briefly described. Our cases suggest the need to consider cystic lymphangioma in the differential diagnosis of lateral neck masses in adults, together with adequate imaging and cytological studies to corroborate the preoperative diagnosis.

“…Both methods are not applicable in fatty tissue. T1 weighted thermal sequences permits a precise control of heat diffusion in tissue [11] [12], it is the easiest way to measure the temperature. An almost linear correlation between laser induced temperature increase and T1 signal loss in liver tissue was used.…”

Abstract-This study aimed to compare MR thermal mapping during Laser-induced Interstitial Thermal Therapy (LITT) to thermal lesions observed macroscopically, in order to estimate the 3D size of the coagulative necrosis. Laser irradiation was performed ex-vivo with a 980 nm laser in pig liver in a open low-magnetic field (0.2T) scanner. The laser light was transmitted through a 1040/600 μm (outer/core diameter) bare-tip silica fiber. The laser energy was applied on a pulsed mode (10 s laser-on, 10 s laser-off) for 12 minutes, power: 6W, energy: 2160 J. MR thermal mapping used T1 method for its simplicity and its efficiency at low magnetic field.

Temperature mapping of magnetic resonance-guided laser interstitial thermal therapy (LITT) in lymphangiomas of the head and neck

Abstract: The results suggest that LITT can be performed safely with tissue preserving of vital structures and can be effective in the treatment of deep tumors, such as lymphangiomas. However, given the nature of the lesion, the potential for recurrence exists no matter what modality is chosen.
