Contrast-enhanced CT immediately following percutaneous microwave ablation of cT1a renal cell carcinoma: Optimizing cancer outcomes

Real-Time Contrast-Enhanced Ultrasound Combined with Ultrasound Monitoring Radiofrequency Ablation Versus Laparoscopic Partial Nephrectomy for cT1a Renal Cell Carcinoma: A Comparative Study with Mid-Term Follow-Up

“…However, multiple studies have reported that insu cient intraoperative ablation and the inability to evaluate the ablation effect in real-time by conventional US, CT, or MRI leads to tumor residue and local recurrence after RFA [28][29][30] . This clinical demand has sparked the development of many new imaging technologies, including CEUS, CECT, and CEMRI, among others, which can assist surgeons in intraoperative margin assessment 16,20,31 . When a residual mass is detected, repeated ablation in the same procedure is organized immediately, signi cantly increasing the complete ablation rate after the initial treatment [30][31][32] .…”

“…It clearly displays the boundaries between the tumor and normal renal parenchyma, providing accurate guidance for ablation electrode placement in the target tumor 11,18,19 . The CEUS allows for quick and effective assessment of radiofrequency ablation (RFA) e cacy during the operation 11,20 . Moreover, it e ciently identi es residual tumor tissues and enhances simultaneous RFA supplementation 2,11,17,20 .…”

Moreover, it e ciently identi es residual tumor tissues and enhances simultaneous RFA supplementation 2,11,17,20 . The US contrast agents exhibit no nephrotoxicity while having minimal adverse reaction rates, rendering them a safe option in compromised or protected renal function, such as in renal transplant recipients and individuals with a previous history of serious allergic reaction to CT or MRI contrast agents 16,18 .…”
