Cineradiography framing frequencies above which of the following frames per second are typically necessary for pediatric coronary angiography?

In pediatric coronary angiography, framing frequencies are essential for capturing high-resolution images that can accurately depict the rapid movements of the heart and blood vessels in children. Children generally have higher heart rates than adults, which requires imaging systems to operate at faster frame rates to ensure that they can capture every significant movement and detail.

A framing frequency of 30 frames per second (fps) strikes a balance, providing enough temporal resolution to track the dynamic events occurring during the procedure without generating excessive amounts of data or compromising image quality. This frequency has been determined as sufficient based on studies that focus on the optimal capture of moving anatomical structures in pediatric patients.

Higher frame rates, such as 60 fps or 90 fps, may be utilized in some situations, but they are often unnecessary for standard coronary procedures and can lead to increased exposure to radiation without significant clinical benefit. Conversely, lower rates, such as 15 fps, are inadequate for capturing the rapid changes that occur during heartbeats, making them unsuitable for these types of exams.
