In the second of a two-part podcast episode, Kalpana Kanal, PhD, and Mahadevappa Mahesh, PhD, discussed the possible impact of new research showing significant declines in CT radiation dosing over the past decade, future research directions and the potential for indication-based diagnostic reference levels (DRLs) in the future.
In the first of a two-part podcast episode, Kalpana Kanal, PhD, and Mahadevappa Mahesh, PhD, reviewed key findings from a study examining CT radiation dosing over the past decade and shared insights from their experience for ensuring optimal radiation dosing for CT scans.
While the P4 trial represents a landmark study on the use of CCTA guidance for percutaneous coronary intervention (PCI), there are pertinent caveats that warrant closer inspection.
New research suggests CCTA may provide salient preoperative insights into planning for percutaneous coronary intervention (PCI) while facilitating similar outcomes as intravascular ultrasound guidance for target-vessel failure.
Emerging CT research suggests that the plexus pancreaticus capitalis 2 (PPC2) pathway or a mass with stranding morphology may significantly increase mortality risk in patients with pancreatic cancer and extra-pancreatic nerve plexus invasion (EPNI).
Emerging research suggests that the benefits of photon-counting CT may be more pronounced in patients with obesity.
The newly cleared Aview Aorta Metrics software reportedly offers automated segmentation of aortic regions and classification of aortic zones based on chest CT images.
