Abstract
We introduce syngo Embolization Guidance (EG) and syngo DynaPBV Body (PBV) as Siemens application software that can support transarterial chemoembolization (TACE).
EG is a so-called automated tumor-feeder detection software. The advantages of this software include the flexibility to utilize both automatic and manual detection modes in a complementary manner, and the adaptability to process a variety of images including C-arm CT (cone-beam CT), IVR-CT (multi-detector row CT) and other modalities like contrast enhanced MRI. We mainly use it with IVR-CT. On the other hand, a major limitation of this software is considered to be its fixed shape as spheres to contour the targeting tumor.
PBV is a software that can visualize the blood volume in organs as a color map. We have developed an acquisition protocol that can capture PBV maps in the same series of dual phase CT during hepatic arteriography with C-arm CT, which is useful in TACE for hepatocellular carcinoma. The advantage of this software is its superiority in detecting small tumors with weak contrast effects and residual / recurrent lesions in Lipiodol accumulated tumors.
Future directions in this field would be the expansion of indications to sites other than the liver and the improvement of performance through artificial intelligence (AI) advancement. To that end, it is necessary to establish a collaboration scheme in which medical doctors, information technology researchers and industry engineers can cooperate as one team.
