Photon-counting detector CT with iodine quantification: improved distinction between bland and neoplastic portal vein thrombosis

Key Points

To determine if iodine density from photon-counting CT can differentiate between bland and neoplastic portal vein thrombosis.
Utilized photon-counting CT to measure iodine density in cases of portal vein thrombosis.
Compared iodine density measurements against established morphological CT features.
Assessed accuracy in differentiating neoplastic from bland thrombosis.
Iodine density measurements accurately distinguished neoplastic thrombosis from bland thrombosis.
Photon-counting CT outperformed existing morphological features in this differentiation.
Findings support improved diagnostic confidence in the context of hepatocellular carcinoma and malignancies.

Abstract

Question Can iodine density measured by photon-counting detector CT improve the differentiation between bland and neoplastic portal vein thrombosis? Findings Iodine density measurements obtained with photon-counting CT accurately differentiated neoplastic from bland portal vein thrombosis and outperformed established morphologic CT features. Clinical relevance Photon-counting CT-derived iodine density enables reliable, noninvasive identification of neoplastic portal vein thrombosis, thereby improving diagnostic confidence and treatment planning in patients with hepatocellular carcinoma and other malignancies.
