In plain language
In 66 patients undergoing coronary angioplasty on a flat-detector system, patient dose rose with the number of vessels treated, and a low-dose fluoroscopy setting cut dose by 39% versus medium-dose. Staff dose was not measured.

What it found
Patient dose rose with the number of vessels treated during percutaneous transluminal coronary angioplasty (PTCA).
Key figures: Mean dose-area product (DAP) 32.71 Gy cm2 (0.57 Gy), 51.24 Gy cm2 (0.9 Gy), 102.03 Gy cm2 (1.77 Gy) for single-, double- and triple-vessel PTCA
A low-dose fluoroscopy setting reduced radiation dose compared with a medium-dose setting.
Key figures: 39% dose reduction
The left anterior oblique (LAO) 45°-caudal 35° projection reached 2 Gy much faster at the medium-dose setting than at the low-dose setting.
Key figures: 2 Gy in 55 min (low-dose) vs 21 min (medium-dose)
Limits to keep in mind
Single-system study of 66 patients measuring patient dose indices only; staff dose was not measured and the country and setting details are not given in the abstract.
