MR-guided discography using an open 1 Tesla MRI system

Abstract

MR-guided discography is accurate and safe. Multiplanar dynamic imaging facilitates the puncture of discs and provides high-quality MR discograms.

MRI-guided biopsy and aspiration in the head and neck: evaluation of 77 patients

“…However, depending on the imaging technique used, different efficacies and limitations apply. Because of the combination of favorable attributes including excellent tissue contrast, true multi-planar imaging capabilities, good vessel depiction, sufficient spatial resolution, and the absence of ionizing radiation, attention and interest in MRI-guided procedures continue to increase [8][9][10][11][12]. However, the available information about diagnostic performance of MRI-guided percutaneous biopsy and aspiration in the head and neck region is limited [7,[13][14][15][16].…”

Evaluation of a MR‐quadrupole imaging coil for spinal interventions in a vertical 1.0 T MRI

“…Depending on the sort of intervention, vertical magnetic fields often require different or even new customized approaches on the design of imaging coils compared with tunnel systems (10, 11). Because of their flexibility and open design, surface single loop coils are frequently preferred for spinal interventions (12, 13). For an optimal access to the spine in open MR scanners with vertical magnetic fields, the patient is usually in a lateral decubitus position, and the single loop surface coil is placed on the patients' back.…”

Maximum instrument length for MR-guided minimal-invasive interventions of the lumbar spine in open high-field MRI

“…For the establishment of new minimal-invasive interventions with MR-guided real time imaging [1][2][3], special methods and instruments are adapted to the MR-environment [4,5]. The length of the instrument depends thereby from space within the scanner.…”
