Iterative image reconstruction techniques appear superior to FBP for the evaluation of heavily calcified vessels with cCTA and should be preferentially used in patients with high calcium scores. Read more

IRIS effect on calcium blooming artifact

Does iterative reconstruction in general and IRIS specifically decreased blooming artifact from calcific plaque in coronary cta and to what extent. Is there a difference between the benefits derived from IRIS between its use with the Definition scanner versus the Flash? Read more

To prospectively evaluate the effect of heart rate, heart rate variability, and calcification on dual-source computed tomography (CT) image quality and to prospectively assess diagnostic accuracy of dual-source CT for coronary artery stenosis, by using invasive coronary angiography as the reference standard.

Case history 49-year-old patient with atypical chest pain and an equivocal bicycle stress test (non-significant ST segment depression in the anterior leads). Question The relative young age of the patient, atypical nature of the chest pain, and equivocal stress test make coronary artery disease rather unlikely. Thus, coronary CTA was performed to rule … Read more
