Deep-learning image reconstruction significantly enhances image quality in dual-energy CT portal venography, aiding liver transplant planning.
Key Details
- 1Study compared deep-learning image reconstruction (DLIR) with adaptive statistical iterative reconstruction (ASiR-V) in dual-energy CT venography using low-dose protocols.
- 2DLIR high strength mode produced better image quality, lower noise, and higher contrast-to-noise and signal-to-noise ratios (p < 0.05).
- 3Radiologists gave DLIR high subjective ratings for image quality, vascular edge sharpness, and diagnostic confidence.
- 4Mean CT dose index volume was 9.79 mGy, DLP 326.26 mGy·cm, and effective dose 4.89 mSv; mean contrast volume was 79.5 mL.
- 555 keV virtual monoenergetic imaging improved iodine contrast effectiveness.
Why It Matters
Improving image quality in CT venography with deep-learning approaches helps deliver safer, lower-dose examinations without sacrificing diagnostic confidence. This has important implications for pre- and post-operative evaluation in liver transplantation, showcasing the clinical utility of imaging AI in challenging applications.
