Adrenal Nodule Characterization at Venous Photon-Counting CT: Liver Virtual Noncontrast versus Virtual Unenhanced Comparison

Key Points

• The study aims to evaluate the accuracy of different imaging techniques for characterizing adrenal nodules.
• Comparative analysis of liver virtual noncontrast reconstructions and virtual unenhanced reconstructions.
• Use of photon-counting CT technology for imaging.
• Assessment based on clinically relevant thresholds for accuracy.
• Liver virtual noncontrast reconstructions more accurately identify adrenal adenomas.
• Improved performance metrics were observed with virtual noncontrast compared to virtual unenhanced.
• Findings suggest a significant advantage in diagnostic accuracy at critical levels.
