Objective To compare the outcomes of cone beam computed tomography (CBCT)-guided radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) with those of traditional spiral computed tomography (s-CT)-guided RFA. Methods This retrospective study analysed data from patients with HCC that underwent RFA guided by either CBCT or s-CT. A number of preoperative and postoperative characteristics, including operation time, ablation time, radiation dose and hospital stay were recorded for all patients. The incidence of intraoperative and postoperative complications was recorded. The therapeutic effect was evaluated at 1, 3 and 6 months after RFA. Results A total of 47 patients with HCC (12 females and 35 males) underwent successful RFA: 21 underwent CBCT-guided RFA and 26 underwent s-CT-guided RFA. Except for one case of pneumothorax in the s-CT group, no serious complications occurred. The objective response rate and disease control rate at 1, 3 and 6 months after RFA showed no significant differences between the two groups. Throughout the 6-month follow-up period, the complete ablation rate was 19 of 21 patients (90.5%) in the CBCT group and 19 of 26 patients (73.1%) in the s-CT group. Conclusions CBCT was a safe and effective guiding modality for RFA in patients with HCC.

Abstract Background Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy of adults. One of the established treatment procedures performed worldwide for HCC is transcatheter arterial chemoembolization (TACE). By using conventional angiography in TACE, we can detect and identify the vascular anatomy of the liver through obtaining 2D images. Recently C-arm cone beam computed tomography (CBCT) is introduced for obtaining cross-sectional and three-dimensional (3D) images for better visualization of small tumors and their feeding arteries. Results The number of detected focal lesions by angiography was 51 compared to 87 focal lesion detected by CBCT; of those, 45 and 77 were active lesions by both procedures respectively. For lesions, less than 1 cm CBCT detected 23 lesions while angiography detected only one lesion. Angiography detected 87 feeding arterial branch while cone beam CT-HA detected 130 branches to the same number of target lesion. Feeder tractability and confidence were better by CBCT. Conclusion CBCT is superior to angiography in tumor detectability, detection of lesions less than 1 cm, feeder detection, and feeder traction; however, conventional angiography and DSA are irreplaceable. Thus, combination of CBCT with angiography during TACE produces better results and less complication.

Percutaneous Cementoplasty

Acetabuloplasty is a valuable palliative adjunct for the treatment of patients with painful metastatic disease to the pelvis in selected cases. We report the case of a 45-year-old woman with morbid obesity and with breast carcinoma who was technically difficult to treat under fluoroscopic guidance due to very poor visualization secondary to her body habitus. It was possible to perform radiofrequency ablation and acetabuloplasty with the use of cone-beam computed tomography for guidance.
