Implication

Cohort study reveals sequential hybrid PET/CT reduces radiation exposure below ten millisieverts in cardiac patients, indicating viable comprehensive non-invasive assessment.

Key Points

To evaluate the feasibility, image quality, and radiation dose of a sequential acquisition protocol for hybrid cardiac PET/CT angiography.
Compared radiation dose and image quality between 10 consecutive patients scanned with spiral MDCT angiography and 10 scanned with sequential acquisition mode.
Assessed feasibility and radiation exposure of a combined rest-stress 15O-water PET perfusion and sequential CTA protocol in 61 consecutive patients.
Mean effective radiation dose was 60% lower with sequential acquisition than with spiral acquisition (7.6 mSv vs. 19.3 mSv, P < 0.001).
Sequential hybrid PET/CTA scanning was feasible in 87% of patients, yielding a mean CT dose of 7.6 mSv and a total hybrid study dose of 9.5 mSv.
