With the launch of EmboGuide during APCCVIR and CIRSE in 2014, Philips introduced a clinical solution for Interventional Oncology that aims to help clinicians more effectively target tumors and their feeding vessels during trans-arterial chemo-embolization (TACE) procedures.

EmboGuide is based on XperCT Dual, a dedicated type of 3D oncologic imaging, which is used to visualize tumors and their feeding vessels.
XperCT Dual allows two phases of a contrast injection to be displayed next to each other. Clinicians can assess the feeder vessels to a tumor in the arterial phase and see the tumor boundaries in the delayed phase. Studies have shown that this novel method is superior to conventional DSA and provides equivalent imaging information to the gold standard of contrast enhanced MRI.³ ⁶
Based on these images, EmboGuide’s automatic feeder detection can detect significantly more feeding vessels than the current treatment standard of DSA.² ⁴
Live Image Guidance then supports selective or super-selective approaches to the embolization target.
At the end of each procedure the dedicated oncologic imaging of XperCT Dual helps to determine the treatment endpoint in TACE for HCC.⁵ With XperCT Dual’s fast acquisition protocol, high resolution and soft-tissue contrast, a study has shown that its dual phase image information even correlates with the tumor response in the one-month follow-up MRI.⁶
5 sec. Fast acquisition = reduces breathing artifacts
Intra-operative MR
Removing as much of a brain tumor as possible during initial neurosurgery can make a critical difference in the prevention of recurrence and the survival rates.
