The clinical value of SWI at 5.0 T ultra‑high field MRI in HCC with Venous System Tumor Thrombosis

Motivation: Looking for an economical and convenient magnetic resonance imaging technique to detect whether hepatocellular carcinoma is complicated with venous tumor thrombi. Goal(s): Using a 5.0T ultra-high field MRI imaging sequence to detect the presence of cancer thrombi in HCC patients without the use of contrast agents. Approach: Statistical analysis of the accuracy of magnetic sensitivity weighted imaging (SWI) in the diagnosis of cancer thrombi using enhanced scanning as the diagnostic criteria. Results: SWI has high diagnostic accuracy for cancer thrombi without the use of contrast agents. Impact: Whether HCC with thrombi is crucial for determining clinical treatment plans. Some patients may not be able to use contrast agents, and the cost of contrast agents is high. SWI can effectively display tumor thrombi, and can reduce patient costs.
