Comparison of the Number of Image Acquisitions and Procedural Time Required for Transarterial Chemoembolization of Hepatocellular Carcinoma with and without Tumor-Feeder Detection Software

Table 2

Number of image acquisitions required for a single session of chemoembolization.

Imaging	Tumor multiplicity	Number of image acquisition		𝑃
