Abstract:
A prospective study in 60 consecutive patients evaluated gain in quality of image using ECG servo-assistance during pulmonary digital subtraction angiography (PDSA). Two groups of 30 comparable patients were randomly allocated to examination with ECG servo-assistance or three images per second technique. Criteria for assessment of quality of image were defined and used to compare results. No significant difference were noted and ECG servo-assistance failed to improve images during PDSA.
