In Vivo Intravascular MR Imaging: Transvenous Technique for Arterial Wall Imaging

Atherosclerosis Imaging Using MR Imaging: Current and Emerging Applications

“…In a recent study on swine, an intravascular MR coil/guide wire (Surgi-Vision, Gaithersburg, Maryland), introduced through the external iliac vein into the inferior vena cava generated excellent images in vivo that correlated well with histologic findings (Fig. 7) [67]. Preliminary studies have also demonstrated the feasibility of MR-guided percutaneous angioplasty in rabbit aorta [68], stent deployment in pig femoral arteries [69] and pig coronary arteries [70], and monitoring of catheter-based gene therapy in pig femoral arteries [71].…”

Implanted, inductively-coupled, radiofrequency coils fabricated on flexible polymeric material: Application to in vivo rat brain MRI at 7T

“…Dedicated microtechnological fabrication processes can also be used to improve the RF field pattern and provide better flexibility and mechanical properties [22][23][24][25][26][27][28]. Alternatively, catheter-based coils can be loopless, consisting of a dipole antenna at the tip of a coaxial cable [29][30][31][32][33]. This principle provides further coil diameter reduction, increased flexibility and improved field pattern near the coil conductor.…”

In Vitro Angioplasty of Atherosclerotic Human Femoral Arteries: Analysis of the Geometrical Changes in the Individual Tissues Using MRI and Image Processing

“…[7][8][9][10]14,31,36,41 It allows a better geometric resolution in in vivo measurements and is becoming increasingly important in recent years. 15,46 Optical coherence tomography (OCT) has also developed rapidly. 4,30,32,38 Despite its limited penetration depth of 1-2 mm, OCT might have the potential for the characterization of smaller vessels such as coronary arteries.…”
