“…This is surprising in that a tendency toward a longer intervention time for the cervical spine can be assumed since the access for this intervention is often more difficult under consideration of the cervical risk structures [38]. Finally the duration of the intervention also depends on the experience of the interventionalist [20]. Therefore, the average intervention duration for the first five patients in a patient collective of Ojala et al [35] was 34 minutes, while the average time for the last five patients was only 23 minutes.…”

“…Although rare, complications such as dissection of the vertebral artery, irreversible nerve damage and spinal, cerebellar, or cerebral infarctions have been described in connection with periradicular cervical injections [11,43]. The interactive PDw FSE sequence that we used allowed guidance and localization of the needle tip with precision comparable to that of CT fluoroscopy [20,44]. With respect to possible complications, the use of crystalloid and non-crystalloid corticosteroids has been controversial even though there is apparently no major difference in medical effectiveness [45].…”

Purpose: To evaluate and compare the costs of MRI-guided and CT-guided cervical nerve root infiltration for the minimally invasive treatment of radicular neck pain. Materials and Methods: Between September 2009 and April 2012, 22 patients (9 men, 13 women; mean age: 48.2 years) underwent MRI-guided (1.0 Tesla, Panorama HFO, Philips) single-site periradicular cervical nerve root infiltration with 40?mg triamcinolone acetonide. A further 64 patients (34 men, 30 women; mean age: 50.3 years) were treated under CT fluoroscopic guidance (Somatom Definition 64, Siemens). The mean overall costs were calculated as the sum of the prorated costs of equipment use (purchase, depreciation, maintenance, and energy costs), personnel costs and expenditure for disposables that were identified for MRI- and CT-guided procedures. Additionally, the cost of ultrasound guidance was calculated. Results: The mean intervention time was 24.9 min. (range: 12???36?min.) for MRI-guided infiltration and 19.7?min. (range: 5???54?min.) for CT-guided infiltration. The average total costs per patient were EUR 240 for MRI-guided interventions and EUR 124 for CT-guided interventions. These were (MRI/CT guidance) EUR 150/60 for equipment use, EUR 46/40 for personnel, and EUR 44/25 for disposables. The mean overall cost of ultrasound guidance was EUR 76. Conclusion: Cervical nerve root infiltration using MRI guidance is still about twice as expensive as infiltration using CT guidance. However, since it does not involve radiation exposure for patients and personnel, MRI-guided nerve root infiltration may become a promising alternative to the CT-guided procedure, especially since a further price decrease is expected for MRI devices and MR-compatible disposables. In contrast, ultrasound remains the less expensive method for nerve root infiltration guidance. Citation Format: ??Maurer MH, Froeling V, R?ttgen R et?al.

“…In the case of a small pole diameter, access is good but the quality of the almost real-time imaging is limited due to the low field strength of these systems [14,25]. Horizontally open MRI scanners with higher field strengths provide higher image quality [12] but commercial availability is currently still limited. Regardless of the system design, MR imaging in real time in "open" magnets during puncture has several advantages: the free selection of slice orientation in MRI can be interactively used with the help of a water-filled syringe or a finger to find the body access point without a light localizer and/or marker; continuous imaging of the needle, puncture path, and target allows safe puncture; oblique puncture trajectories can be better maintained in the freehand technique; efficient puncture is possible [2,4,13,26].…”

Background MRI is attractive for guiding and monitoring interventional procedures due to its high intrinsic soft tissue contrast and the possibility to measure flow and cardiac function. Methods Technical solutions have been developed for all procedural steps including imaging guidance, MR-safe catheters and instruments and patient monitoring. This has led to widening of the clinical applications. Interventional MRI is becoming increasingly important for the treatment of patients suffering from malignant diseases. The detectability of masses and consequently their accessibility for biopsy is higher, compared to other modalities, due to the high intrinsic soft tissue contrast of MRI. Temperature-dependent sequences allow for minimally invasive and tissue-sparing ablation (A-0 ablation). Conclusion Interventional MRI has become established in the clinical routine for a variety of indications, including biopsies and tumor ablation. Since the economic requirement of covering costs by reimbursement is met and interventional MRI decreases the mortality and morbidity of interventional procedures, broader application of interventional MRI can be expected in the clinical routine in the future.

“…In contrast to X-ray fluoroscopy and computed tomography, interventional MRI allows for image guidance without health risks from exposure to ionizing radiation [11][12][13][14][15][16][17][18][19][20][21][22]. To the best of our knowledge, no prior reports have been published assessing interventional MR imaging of the sacroiliac joints in children.…”
