A novel class of tungsten-based contrast agents (WO3-x NPs) with excellent biocompatibility and minimal systemic toxicity for DECT was designed and presented a promising method for the accurate diagnosis of liver cancer.
Dual-energy computed tomography (DECT) is a commonly used imaging technique for detecting and diagnosing liver cancer. Currently, it is performed using clinically approved iodinated small molecule contrast agents (CAs). However, these iodinated CAs have several drawbacks, including sub-optimal contrast generation and contra-indication in patients with renal insufficiency. Herein, we synthesized tungsten-based CAs (i.e., WO3-x NPs) with excellent biocompatibility and investigated their effectiveness in DECT imaging. WO3-x NPs significantly enhanced the contrast between liver tumors and normal liver tissues as indicated by in vivo DECT imaging. Furthermore, WO3-x NPs exhibited excellent biocompatibility and minimal systemic toxicity. This study introduces a novel class of CAs for DECT and presents a promising method for accurate early diagnosis of liver tumors. In this study, a novel class of CAs (i.e., WO3-x NPs) with excellent biocompatibility and minimal systemic toxicity for DECT was designed and presented a promising method for the accurate diagnosis of liver cancer.
