In plain language
In 22 adrenal venous sampling procedures, dynamic trace digital angiography and spot fluoroscopy roughly halved measured patient dose and operator radiation exposure compared with conventional digital subtraction angiography (DSA), with comparable image quality. The study was small.

What it found
Operator radiation exposure was roughly halved with DTDA and spot fluoroscopy compared with conventional DSA with collimation.
Key figures: 17.1 ± 14.8 vs. 36.6 ± 21.7 μSv, p = 0.013
Total dose-area product was significantly lower with DTDA and spot fluoroscopy.
Key figures: 38.6 ± 25.9 vs. 88.2 ± 53.6 Gy cm2, p = 0.006
Acquisition dose-area product (DAP) with DTDA was much lower than with conventional DSA.
Key figures: 5.3 ± 3.7 vs. 29.1 ± 20.1 Gy cm2, p < 0.001
Patient peak skin dose was significantly lower with DTDA and spot fluoroscopy.
Key figures: 403 ± 340 vs. 771 ± 416 mGy, p = 0.030
Image quality of DTDA was equivalent to DSA and higher than digital angiography.
Key figures: 4.4 ± 0.6 vs. 4.3 ± 0.8, p = 0.651; vs. 3.8 ± 0.9, p = 0.011
Limits to keep in mind
Very small two-group comparison (11 patients each) with no stated randomization or design details, in a single procedure type; operator dose is a dosimeter measurement, not a health outcome.
