“…In contrast, active tracking gives the operator direct instrument control with immediate feedback under real-time MR image guidance. A number of active tracking techniques have been developed, including optical tracking with an infra-red camera and mirrors [14,15] and also the use of MR micro-receiver coils within the device to induce local inhomogeneities within the magnetic field [16][17][18]. Although optical tracking provides a wireless approach, it requires line-of-sight access for accurate guidance which can be problematic in many MR scanner designs.…”

MRI-guidance is increasingly used for minimally-invasive procedures, such as biopsy, and requires real-time active tracking of surgical instruments. Although optical and MR-based fiducial tracking devices have been used, these systems rely on complex contact with the operator or line-of-sight access for effective operation. A more straight-forward and clinically robust method is required to allow interactive real-time slice positioning of MR scan planes during interventional procedures. This study evaluated the use of a wristwatch-mounted, low cost wireless interface device for real-time MRI guidance. The device was designed to interact with software for planning rather than instrument guidance. The wireless device was integrated with two novel, open interventional magnet systems operating at 0.17T and 0.5T and utilized a novel customized graphic user interface (GUI) to assess interventional capability.

“…After the introduction of MRI systems suitable for MRguided interventions and of special MRI-compatible alloys, several studies on spinal injection therapy were performed in open low-field devices with promising results [13][14][15][16]. This study describes the feasibility of lumbosacral injection therapy in open high-field MRI.…”

“…There are, however, very few studies on MR-guided injection therapies. These were performed in open lowfield devices [13][14][15][16] or, more recently, in a wide-bore high-field MRI system [17,18]. So far, no studies of spinal injection therapy in an open high-field system with vertical field orientation have been described in the literature.…”

“…Such a tightly sequenced double procedure makes contemporary direct MRAr more expensive, resource-intensive, and difficult to schedule. To address this problem, Hilfiker et al [9] and Ojala et al [10] reported the use of an open MRI scanner configuration where needle insertion and contrast injection were performed directly inside scanner in the same setting. Lewin et al [11], and the later Kreitner et al [12] and Fahrig et al [13], reported the use of an ''open C-arm scanner'', which consists of a vertically open MRI and optically co-registered C-arm fluoroscope.…”

Magnetic Resonance Imaging (MRI) offers great potential for planning, guiding, monitoring and controlling interventions. MR arthrography (MRAr) is the imaging gold standard for assessing small ligament and fibrocartilage injury in joints. In contemporary practice, MRAr consists of two consecutive sessions: (1) an interventional session where a needle is driven to the joint space and MR contrast is injected under fluoroscopy or CT guidance; and (2) a diagnostic MRI imaging session to visualize the distribution of contrast inside the joint space and evaluate the condition of the joint. Our approach to MRAr is to eliminate the separate radiologically guided needle insertion and contrast injection procedure by performing those tasks on conventional high-field closed MRI scanners. We propose a 2D augmented reality image overlay device to guide needle insertion procedures. This approach makes diagnostic high-field magnets available for interventions without a complex and expensive engineering entourage. In preclinical trials, needle insertions have been performed in the joints of porcine and human cadavers using MR image overlay guidance; in all cases, insertions successfully reached the joint space on the first attempt.
