Intravascular MR imaging and intravascular MR-guided interventions

International Journal of Cardiovascular Interventions, 1999
Intravascular MR technology, using an intravascularly placed MR receiver probe to acquire high-resolution angiographic MR images (i.e. intravascular MR imaging) and to guide cardiovascular interventional therapies (i.e. intravascular MR-guided interventions), is a new, very attractive development in the field of MR imaging.

Resolution limitations in intravascular ultrasound imaging

IEEE 1991 Ultrasonics Symposium, 1993
Interest in the use of ultrasound to characterize the structure and composition of blood vessel walls has risen dramatically as a result of the development of intravascular ultrasonic imaging transducers mounted on the tips of small-diameter catheters.

Intravascular Imaging With Ultrasound

SPIE Proceedings, 1988
One of the major unresolved problems in the development of laser angioplasty is in monitoring the process of plaque ablation in real-time to provide the necessary operator feedback. As part of a project to test the feasibility of intravascular imaging with ultrasound we have developed, constructed, and tested a 20 MHz transmitter/receiver which can ...

Intravascular imaging methods for venous disorders

International Journal of Angiology, 2000
The purposes are to assess the problems associated with intravascular imaging methods such as angioscopy and intravascular ultrasound (IVUS) and to evaluate their efficacy through the results of our observations. A total of 54 limbs in 53 patients, 50 patients with chronic venous insufficiency and 3 patients with deep vein thrombosis, were diagnosed ...

Intravascular Ultrasound Imaging

Archives of Surgery, 1994
Intravascular Ultrasound Imaging contains a clear overview of the basics of intravascular ultrasound physics with helpful details to avoid problems when starting out with this imaging modality. The authors present how-to techniques and discuss the advantages and pitfalls of three-dimensional reconstruction and its future applications.

Intravascular Image Interpretation

2011
Intravascular ultrasound (IVUS) is an imaging modality often used as a supplement to coronary angiography and allows accurate assessment of the lumen, vessel wall, and atherosclerotic plaque. A coherent interpretation of the IVUS images requires identification of the image artefacts that emerge during IVUS interrogation and can often be quite difficult.

Intravascular Imaging and Haemodynamics

2011
Shear stress on the endothelial surface has been implicated in atherosclerosis localization, plaque vulnerability, and remodeling behavior of the arterial wall, as well as in-stent restenosis following percutaneous coronary interventions. The purposes of this chapter are to introduce haemodynamic shear stress, briefly explain the methodology for ...
