AJR Podcasts

Full article: https://www.ajronline.org/doi/10.2214/AJR.23.30272 Peter Gunderman, MD discusses a recent AJR study that finds that a free-breathing accelerated cine sequence with deep learning reconstruction is just as accurate as standard breath-hold SSFP sequences in estimating left ventricular measurements. An accurate free-breathing cine sequence could benefit patients who have difficulty holding their breath and decrease scanning times, but there are limitations to the study that may hinder wider adoption.

It shows that pure ground-glass nodules have better surgical outcomes and may be monitored noninvasively, whereas nodules with increased density may need surgery.

With a focus on the need for pediatric-specific datasets CAD systems, the podcast analyses the study's methodology and results.

No statistically significant difference was observed between these two groups, including in subgroups of patients on active surveillance and patients with no prior prostate cancer history.

However, Schoen et al. prove otherwise by measuring CT net scan energy consumption and estimated savings on one of their scanners at Wake Forest. The authors found that a high correlation between CT dose report metrics and CT scanners' net scan energy consumption and that net scan energy savings could be extracted from a reduction in dose report metrics without requiring a sensor. The authors also measure the impact on CT energy savings, which is greatly impacted by reducing idle state energy consumption, or the energy the CT produces from being "on."
