Does Optical Coherence Tomography Optimise Results of Stenting

"Optical Coherence Tomography (OCT) is a recent imaging modality that yields cross-sectional images with a resolution 10 times greater than that of intravascular ultrasound (IVUS). OCT uses a near-infra-red light source to obtain images of the interior walls of the coronary arteries and is increasingly used to evaluate vulnerable atherosclerotic plaques and assess placement and response to stenting.~OCT images are acquired by automated pullback over 2 to 3 seconds of the light source that yields a helicoidal image of a longitudinal segment of 50 mm. Intravascular imaging is obtained by injecting contrast medium or saline solution."
