Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Optical Coherence Tomography in Acute Coronary Syndromes

Reviews in Cardiovascular Medicine
Angiography remains the standard imaging modality during cardiac catheterization; however, this technique provides only a two-dimensional representation of the coronary lumen, which limits the assessment of vessel wall pathology.
