“…As a result, some attempts were made to minimize the posterior approach by developing percutaneous techniques for translaminar 9 or pedicle screw placement. 14,15 Yet, due to the high complexity of these surgical procedures, applying, for example, open magnetic resonance imaging (MRI) techniques, computed tomography (CT) navigation, or instruments susceptible for failure, currently, hardly any of these percutaneous posterior fixation techniques is carried out routinely.…”

Results of this study indicate that the new Lumbar Facet Interference Screw fixation yields initial biomechanical stability similar to translaminar screw fixation, yet inferior biomechanical stability compared to pedicle screw fixation. Although these results are encouraging, additional biomechanical studies including cyclic loading tests have to evaluate the mid- and long-term stabilization capacity of this new minimally invasive fixation technique before human application.

“…The experiences of many research groups have confirmed the feasibility and benefits of MRI guidance (2, 5–8, 19). Intraoperative MRI has been implemented for a variety of intra‐ and extracranial procedures; it provided continuous visual feedback, which can be helpful in all stages of intervention without affecting the duration of the procedure or the incidence of complications (4, 9, 20).…”

“…OPEN INTERVENTIONAL MRI systems allow diagnostic studies as well as interventional procedures. The use of these systems to guide biopsies or therapeutic procedures has been described previously for different anatomic regions (1–4). Neurosurgical interventions, especially MRI‐guided brain tumor biopsies or ablations, have been the subject of numerous studies (5–9), as has head and neck biopsy for deep‐seated lesions (10–13).…”

Magnetic resonance imaging (MRI) allows excellent tissue characterization in the area of the petroclival region and can depict lesions not visualized with ultrasound or computed tomography (CT). The aim of this study was to demonstrate the clinical feasibility and utility of an interactive MR‐guidance system to target and biopsy tumors in the petroclival region. MRI‐guided biopsies of 10 patients with tumors in the clivus and petrous apex were performed in an open 0.5‐T MR system. Lesions were targeted through a transsphenoidal or transnasal approach. Imaging during biopsies was achieved by a combination of standard and interactive mode. T1‐weighted spin‐echo, T2‐weighted fast spin‐echo (FSE), and three‐dimensional T1‐weighted gradient‐echo (GRE) scans (standard mode) were selected to provide optimal tissue characterization for both the lesion and surrounding structures and varied according to the anatomic site. For interactive imaging, T1‐weighted GRE and T2‐weighted FSE sequences were used. We performed MRI‐guided transsphenoidal biopsies in 10 patients who had lesions identified by CT (n = 5) and/or MRI (n = 10). The indications for biopsies were to differentiate between suspected malignant processes (n = 4 ) and benign processes (n = 6). Lesions adjacent to structures like the internal carotid artery were accurately targeted in particular. All biopsies were performed successfully and were the basis for selection of further treatment. No complications occurred during the procedures. An open MR system allows interactive control of biopsies in the area of the petroclival region, providing maximum patient safety and diagnostic accuracy not possible in other systems. The advantages of MRI tissue characterization are combined with an interactive, one‐step method of localization and targeting, as well as tissue sampling. J. Magn. Reson.

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

et al. 2004

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.
