“…It is worth noting that the postprocedural complication rates of thermal ablation vary greatly, from 2.2-53.2% [14,15]; we cannot say that this is not in uenced by the method of imaging guidance. Both types of imaging guidance have their own disadvantages; to overcome these limitations, various methods have been proposed by researchers to achieve this goal, such as CT/MRI-CEUS and US-CEUS fusion imaging techniques and multimodality imaging-compatible insertion robots [16][17][18][19]. All these measures can aid operators in performing technically challenging procedures, with the potential of reducing the procedure time and radiation dose.…”

“…The median follow-up period was 14 (12)(13)(14)(15)(16)(17)(18)(19)(20) months. During the follow-up period, 8 patients (combination group: 2 patients, CT group: 2 patients, US group: 4 patients) experienced local recurrence and received repeat MWA, and the local recurrence rates were 5.9%, 6.7%, and 16.7% in the combination group, CT group, and US group, respectively.…”

Background We prospectively evaluated the safety and effectiveness of percutaneous microwave ablation (MWA) using combined computed tomography (CT) and ultrasound (US)-guided imaging in patients with BCLC-A1-3 hepatocellular carcinoma (HCC) given that they have shortcomings when used alone. Methods We included 88 consecutive patients with single HCC who were treated with transcatheter hepatic arterial chemoembolization (TACE). The patients were divided into 3 groups at random by using draw lots 1 week after TACE. The combination group (34 patients) received MWA under the guidance of CT and US, while the single group (CT group, 30 patients; US group, 24 patients) received MWA under the guidance of CT or US alone. Contrast-enhanced MRI or CT scans were performed in all patients 1, 3, 6 and 12 months after the procedure. The study endpoints included the treatment time, puncture time, local recurrence rate, and adverse events. Results The median diameter of the lesions was 3.1 (1.5–4.2) cm. The median treatment time was 38.6 (30–45) min and 36.7 (30–47) min in the combination group and US group, respectively. The median puncture number was 1.2 (1–2) times and 1.1 (1–2) times, respectively. Both were significantly less than in the CT group (45.8 min and 4.2 times). The local recurrence rate was 5.9% in the combination group, which was significantly inferior to that in the US group (16.7%). The grade C complication rate in the combination group was 5.9%, while it was 13.3% and 8.3% in the CT group and US group, respectively. There was a statistically significant difference between the combination group and CT group. Conclusions Using CT- and US-guided microwave ablation in patients with BCLC-A1-3 hepatocellular carcinoma appeared to be much better in terms of security and efficiency than the use of microwave ablation under the guidance of CT or US alone.

Background: Percutaneous thermal ablation has become the preferred therapeutic treatment option for liver cancers that cannot be resected. Since ablative zone tissue changes over time, it becomes challenging to determine therapy effectiveness over an extended period. Thus, an immediate post-procedural evaluation of the ablation zone is crucial, as it could influence the need for a second-look treatment or follow-up plan. Assessing treatment response immediately after ablation is essential to attain favorable outcomes. This study examines the efficacy of image fusion strategies immediately post-ablation in liver neoplasms to determine therapeutic response.Methodology: A comprehensive systematic search using PRISMA methodology was conducted using EMBASE, MEDLINE (via PUBMED), and Cochrane Library Central Registry electronic databases to identify articles that assessed the immediate post-ablation response in malignant hepatic tumors with fusion imaging (FI) systems. The data were retrieved on relevant clinical characteristics, including population demographics, pre-intervention clinical history, lesion characteristics, and intervention type. For the outcome metrics, variables such as average fusion time, intervention metrics, technical success rate, ablative safety margin, supplementary ablation rate, technical efficacy rate, LTP rates, and reported complications were extracted.Results: Twenty-two studies were included for review after fulfilling the study eligibility criteria. FI's immediate technical success rate ranged from 81.3% to 100% in 17/22 studies. In 16/22 studies, the ablative safety margin was assessed immediately after ablation. Supplementary ablation was performed in 9 studies following immediate evaluation by FI. In 15/22 studies, the technical effectiveness rates during the first follow-up varied from 89.3% to 100%.
