Interventional oncology

Typical CT Interventional suite set up with MDCT, ultrasound, the ablation equipment plus instruments nursing and radiographic staff. Often anaesthetic staff are present also.

An echogenic cloud is visible during thermal ablation and this tends to obscure the needle electrode for subsequent placement.

(A) Contrast enhanced CT shows a small renal cell carcinoma at the upper pole of the left kidney. (B & C) Coronal and sagittal CT reformat shows the overall coverage of the multi-tines RFA needle electrode after insertion into the tumour under CT guidance.

TACE of HCC in segments 2/3. Initial angiogram in the (A) arterial and (B) parenchymal phase shows an abnormal blush corresponding to the tumour. (C) Post chemoembolisation angiogram confirms absence of residual tumour enhancement. (D) Follow-up CT scan demonstrates dense lipiodol staining within the tumour.
