Michael Hadley: Photon-Counting CT Offers Good Diagnostic Accuracy for Detecting In-Stent Restenosis
Michael Hadley, System Director of Advanced Cardiac Imaging at Northwell Health, shared on LinkedIn:
”Photon-counting CT offers good diagnostic accuracy for detecting in-stent restenosis, overcoming artifacts that have plagued prior generations of scanners.
In a blinded study of 283 stented lesions, photon-counting CT was compared to quantitative coronary angiography for detection of obstructive in-stent restenosis (≥50%).
Compared to cath, photon-counting CT demonstrated lesion-level negative predictive value of 96.4% and overall accuracy of 88.9%.
Impressively, only 1% of scans were indeterminate, with good diagnostic performance regardless of stent diameter.
