“…7 These findings replicate results of other studies investigating the efficacy of a frame rate reduction from 15 fps to 7.5 fps in reducing radiation dose. [8][9][10] In one retrospective cohort study, a conventional PCI protocol with 15 fps was compared with a protocol using 7.5 fps during fluoroscopic guidance and 10 fps during cineangiographic acquisition as well as selective fluoroscopic image storage. 8 That study found a significant reduction in total air kerma and total DAP in the radiation reduction protocol compared with the conventional protocol.…”

ObjectiveCoronary artery disease (CAD) is an important cause of morbidity and mortality all over the world. Cardiac catheterization is one of the most important treatment modalities in managing CAD. Unfortunately, cardiac catheterization is associated with significant ionizing radiation exposure to both patients and personnel. This study aimed to compare the safety and efficacy of a lower video frame rate of 7.5-fps compared with the standard frame rate of 15-fps.Materials and MethodsWe retrospectively collected and reviewed data from 84 cardiac catheterizations performed between January and February 2020 at a single tertiary center. The patients were divided into two groups based on frame rate: 15-fps (n=42) and 7.5-fps (n=42). We compared the two groups in terms of demographic data, procedural characteristics, radiation dose, and patient outcomes.ResultsCumulative air kerma was significantly lower in the 7.5-fps group (266.576 mGy) compared to the 15-fps group (524.140 mGy), p=0.0018. Similarly, total dose area product was lower in the 7.5-fps group (15335.617 mGy × cm2compared to the 15-fps group (34784.095 mG × cm2), p = 0.0003. Despite this, total fluoroscopic time did not differ between the two groups 7.74 minutes in the 15-fps group and 8.462 minutes in the 7.5-fps group, p = 0.4023). In addition, 30-day mortality 0% in both groups and there were no differences in the number of repeat PCIs performed within 30 days (6 in 7.5-fps and 3 in the 15-fps group), p = 0.2899.ConclusionDuring cardiac catheterization, a fluoroscopy rate of 7.5-fps is associated with lower radiation dose compared to 15-fps without an associated increase in fluoroscopy time, mortality or repeat PCI. Therefore, interventionalists should consider using a fluoroscopy rate of 7.5-fps during cardiac catheterization.

“…For example, Pyne et al [19] compared a standard dose cohort (15 f/s for fluoroscopy and cine angiography) and a reduced dose cohort (10 f/s for fluoroscopy and cine angiography), revealing that the reduced dose cohort exhibited a significant reduction in the mean total X-ray dose (1763.1 mGy vs. 1179.1 mGy; p<0.0001). In addition, Sadamatsu et al [20] described that a change in the frame rate from 15 f/s to 7.5 f/s for fluoroscopy could significantly reduce AK (701.4 ± 427.9 mGy vs. 936.8 ± 623.9 mGy; p=0.02). Moreover, Hansen et al [21] found that when the frame rate was decreased from 10 to 7.5 f/s during the PCI procedure, AK significantly reduced (703.0 vs. 621.0; p=0.041).…”

Background: Although radiation is beneficial for invasive procedures, it can be harmful. Several factors such as equipment settings, patient characteristics, and a physician's procedure affect the dose of such radiations. Here we aimed to evaluate the X-ray dose and image quality after reducing both the default rate (frames per second: f/s) and cine exposure dose for coronary angiography. Methods: The study retrospectively reviewed 215 patients who underwent with a standard frame rate and standard cine dose (15 f/s and 0.200 μGy/fr) or a low frame rate and low cine dose (7.5 f/s and 0.120 μGy/fr, referred to as dose management protocol: DMP group). All the patients were performed diagnostic angiogram without additional therapy. The primary endpoint was total air kerma (AK; mGy), and the secondary endpoints were radiation time, contrast volume, procedure complication rate, and a 10-point scale to assess the image quality. Results: There were no differences with regard to baseline demographics and risk factors between both the groups. Total X-ray dose was significantly low in the DMP group compared with the standard group (181.4 mGy vs. 352.7 mGy; p<0.01). There were no differences with respect to radiation time, contrast volume, and complication rate between both the groups. The diagnostic value in the DMP group was not inferior to that in the standard group (8.79 ± 1.05 vs. 8.91 ± 0.91; p=0.37). Conclusions: Our innovative alteration of reducing both the frame rate and cine dose for angiography can dramatically decrease the total AK without sacrificing image quality.
