Abstract:
A 70's man had been treated with gemcitabine(GEM)and nab-paclitaxel(nabPTX)combination for advanced pancreatic tail cancer with splenic invasion and liver metastases. However, the primary lesion was not controlled, then intensity-modulat- ed radiation therapy(76.5 Gy/17 Fr)was performed for primary lesion. Three grown hypovascular liver metastases were detected by follow-up EOB-MRI and PET-computed tomography(CT)imaging with 18F-FDG. Unfortunately, these lesions were not detected by intravenous injection of contrast media with CT nor ultrasonography. Radiofrequency ablation(RFA) under computed tomography during arterial portography(CTAP)guidance was performed. The patient has been alive for 1 year after RFA with no recurrence. CTAP could be a feasible image guidance for the treatment of hypovascular liver metastases with RFA.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
