Why the study?
Does 64 and 16 detector MSCT accurately measure in-stent luminal diameter compared to IVUS?
Population
Four commercially available bare metal and polymer-coated drug-eluting stents (Vision, Cypher, Taxus, Liberté)
Comparison
64 and 16 detector multislice computed tomography vs Intravascular ultrasound (IVUS)
Design
Preclinical

Caution against MSCT for ISLD quantification in stents; animal data leaves open human validation versus IVUS.
Does 64 and 16 detector MSCT accurately measure in-stent luminal diameter compared to IVUS?
Both 16- and 64-slice MSCT significantly underestimate in-stent luminal diameter compared to IVUS, limiting their utility for quantifying in-stent restenosis.
