Ultrafast Cone-Beam Computed Tomography: A Comparative Study of Imaging Protocols during Image-Guided Therapy Procedure

Figure 1

Frames (a) and (b) represented the images obtained from a 62-year-old patient during TACE therapy, generated using ultrafast cone-beam CT with imaging protocol 1. Pretreatment magnetic resonance cross-sectional images ((c) and (f)) show a clear view of embedded tumor in the hepatic parenchyma. Hepatic tumor detection was insufficient using imaging protocol 1 data (tumor indicated using black arrow) compared to imaging protocol 2 due to a reduction of contrast material in the tumors. Coronal reconstructed images ((d) and (e)) were acquired using imaging protocol 2 during a 60-year-old patient TACE examination. The images show excellent tumor(s), feeding vessels, and hepatic parenchymal visualization; furthermore, notice the strong contrast material enhancement of the tumors with little or no artifacts.
