Ultrasound-guided radiofrequency is generally a safe treatment for liver masses and carries an acceptable level of risk, but patients with large tumors and baseline liver function impairment have a higher risk of complications, according to researchers in Taiwan.
The use of high-intensity focused ultrasound for various therapeutic applications has continued to grow since Lynn et al first proposed it in 1942.1 Advances in medical imaging technology in the last two decades have led to its widespread use in both research and clinical practice for the treatment of benign and malignant tumors, hemostasis, uterine fibroids, and other conditions.
“I predict that lung radiofrequency ablation is going to be very big indeed,” said Dr. Alice Gillams at the beginning of her two presentations on Saturday examining factors influencing tumor recurrence and incidence of pneumothoraces.
This first Ultrasound Source journal review includes a head-to-head comparison between MRI and sonography in patients with sphincter defects and an interesting study with a large patient population proposing FAST scanning as a reliable selection tool for patients needing laparotomy. We also recommend a study evaluating two ultrasound imaging techniques for ablation guidance; a trial comparing sonography, MRI, and CT to define surgical margins in patients with chest wall tumors; and an interesting British study using 3D sonography to gauge abdominal aortic aneurysms.
Cryotherapy is often portrayed as radiofrequency ablation’s little brother. But the thermal ablation technique is muscling in on malignancies in several organ systems, according to studies presented Tuesday at the RSNA meeting.
Radiofrequency ablation is effective for treating some liver metastases of ovarian cancer and could spare patients from repeated surgeries, according to a retrospective study from Massachusetts General Hospital.
