Which imaging technology combines features of both invasive and noninvasive imaging?

Intravascular Ultrasound (IVUS) effectively combines features of both invasive and noninvasive imaging techniques. This modality allows for detailed imaging of blood vessels from within the lumen, providing real-time visualization of vascular structures and pathology in a way that noninvasive imaging methods like MRI cannot achieve.

IVUS is used during catheter-based interventions, which gives it an invasive aspect as it requires the insertion of a catheter. It serves to visualize the interior of arteries and veins, helping clinicians assess and guide procedures such as stent placements or angioplasty. The benefit of IVUS is that it offers insights that complement the exterior views obtained through noninvasive imaging modalities, thereby providing a comprehensive understanding of vascular health and disease.

This unique feature of being able to assess vascular conditions from within while still providing a level of detailed, noninvasive-like imaging makes IVUS particularly valuable in vascular intervention practices.
