The role of functional MR imaging in the assessment of tumor response after chemoembolization in patients with hepatocellular carcinoma.
To assess treatment response of hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE) with use of diffusion and dynamic contrast medium-enhanced magnetic resonance (MR) imaging. ⋯ After TACE, tumors demonstrated decreased size and enhancement with increases in ADC values. In this cohort, diffusion and dynamic contrast medium-enhanced MR imaging parameters were significantly altered after TACE, and these could be useful tools in the assessment of tumor response.

Endovascular embolization of symptomatic arteriovenous fistulas secondary to lower-limb in situ venous bypass grafts.
To evaluate the safety and efficacy of endovascular treatment of symptomatic arteriovenous (AV) fistulas associated with femoropopliteal in situ venous bypass grafts. ⋯ Embolization of symptomatic AV fistulas secondary to lower-limb in situ venous bypass is a safe and efficient alternative to surgical ligature. Complete regression of clinical symptoms is less likely when the bypass is performed with use of the femoral vein.

Comparative StudyRadiofrequency renal ablation: in vivo comparison of internally cooled, multitined expandable and internally cooled perfusion electrodes.
To evaluate the in vivo efficiency of radiofrequency ablation using an internally cooled-perfusion (ICP) electrode for inducing coagulation necrosis compared with those of RFA using internally cooled or multitined expandable electrodes in porcine kidneys. ⋯ Radiofrequency ablation using an ICP electrode showed better performance at creating coagulation necrosis than radiofrequency ablation using internally cooled or multitined expandable electrodes in this porcine renal model.
