Impact of real-time contrast-enhanced ultrasound on thyroid function in microwave ablation treatment of thyroid tumors.
Article in American journal of cancer research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate the impact of contrast-enhanced ultrasound on the efficacy of microwave ablation in the treatment of benign thyroid tumors, as well as its effect on thyroid function, to assess its application value.
methodsWe retrospectively analyzed data from 60 patients with benign thyroid nodules treated at Sichuan Provincial People's Hospital from January 2021 to December 2021. All patients underwent microwave ablation. Based on the intraoperative assessment of the ablation effect, they were divided into a contrast-enhanced ultrasound group (n=34) and a conventional ultrasound group (n=26). Postoperatively, the treatment outcomes were classified into complete ablation or the presence of residual nodules. We also assessed the recurrence rate one year after treatment, along with inflammatory factors, stress response indicators, and effects on thyroid function.
resultsThe complete ablation rate for thyroid nodules in the contrast-enhanced ultrasound group was significantly higher than that in the conventional ultrasound group (P<0.05). Intraoperative measurements revealed lower ablated nodule volumes, bleeding volumes, and in situ replacement rates in the contrast-enhanced ultrasound group, with statistically significant differences (P<0.05). Preoperative thyroid function hormone indicators, inflammatory factors and stress response indicators did not significantly differ between the two groups. Postoperatively, both groups had lower levels of free triiodothyronine (FT3) and free thyroxine (FT4), along with higher levels of thyroid-stimulating hormone (TSH), white blood cells (WBC), serum C-reactive protein (CRP), interleukin-6 (IL-6), norepinephrine (NE), epinephrine (E), and cortisol (Cor) compared to preoperative levels. However, the contrast-enhanced ultrasound group demonstrated higher FT3 and FT4 levels and lower WBC, serum CRP, IL-6, NE, E, Cor and TSH levels than the conventional ultrasound group, with statistically significant differences (all P<0.05). No statistically significant differences in complication rates were observed between the two groups.
conclusionContrast-enhanced ultrasound in microwave ablation for benign thyroid nodules can improve the complete ablation rate, reduce recurrence, and have a minimal impact on thyroid function, without increasing complication rates. It is recommended for clinical use.
