Optical coherence tomography (OCT) – Cardiology MCQ – Answer

Optical coherence tomography (OCT) compared to intravascular ultrasound (IVUS) has – Correct answer: 1. OCT has higher resolution but lower depth penetration

Optical coherence tomography (OCT) has much higher resolution compared to intravascular ultrasound. It has the resolution of the range of 10 – 20 microns, which is an order of magnitude better than that of intravascular ultrasound. But the limitation is the lower depth of tissue penetration which is only 2 to 3 millimeters, compared to the 10 millimeter tissue penetration of current intravascular ultrasound probes. This is likely to change as technology evolves. Read more on Optical coherence tomography (OCT).
