This prospective randomized study compared submucosal resection (SMR) with radiofrequency turbinate volume reduction (RFTVR) in 60 patients with inferior turbinate hypertrophy. Both procedures significantly reduced turbinate volume and improved nasal obstruction symptoms and nasal inspiratory peak flow by 2 months.…

This study tested noninvasive 13.56 MHz radiofrequency electric fields as a treatment adjunct for pancreatic ductal adenocarcinoma in cell lines and mouse xenograft models. The authors report RF exposure caused cytotoxicity in PDAC cells via autophagy (not apoptosis) and that normal pancreatic ductal epithelial cells…

This experimental rabbit study evaluated radiofrequency microtenotomy (Rf-mt) in prostaglandin E1-induced Achilles tendon degeneration. Rf-mt increased vascularity based on histopathology and immunohistochemistry. However, the authors report no significant difference in tendon healing compared with a sham-control…

This animal study evaluated a therapeutic 120 Hz pulsed EMF device (10–20 mT) in C3H mice bearing implanted murine mammary adenocarcinoma tumors. Across seven treated groups, EMF exposure over 12 days was reported to suppress tumor growth, with specific dose/time regimens described as most effective. The authors also…

This study evaluated pulsed radiofrequency (PRF) neuromodulation of the suprascapular nerve in 11 patients with chronic shoulder pain from adhesive capsulitis and/or rotator cuff tear. Pain (VAS) and shoulder-related quality of life/function (OSS) were assessed before treatment and monthly after PRF for up to 9…

This observational study followed 36 patients for 2 years after temperature-controlled radiofrequency tissue volume reduction for turbinate hypertrophy. Patients reported significantly lower VAS symptom scores (nasal obstruction, headache, rhinorrhoea, anosmia) after treatment compared with baseline. Urban residence…

This experimental animal study evaluated whether a radiofrequency method could induce thrombosis within an abdominal aortic aneurysm sac to potentially prevent endoleaks after endovascular repair. Six dogs received radiofrequency blood clotting of the sac and then stent-grafting, compared with a historical group of…

This study compared two non-invasive acupoint stimulation methods—TEAS and PEMF—as alternatives to manual acupuncture for recovery from exercise-induced muscle fatigue. Using 2 Hz stimulation (PEMF magnetic flux 30.92 mT), the authors report faster recovery of EMG median frequency and improved peak torque recovery in…

This retrospective cross-sectional study evaluated pulsed radiofrequency (PRF) for chronic pain in patients who did not respond to conventional treatment. Across 24 patients treated at different anatomical regions, 66.7% reportedly achieved at least a 50% reduction in VAS pain scores over a mean follow-up of 8.5…

This study compared coronary plaque assessment by 64-slice multislice computed tomography (MSCT) with virtual histology intravascular ultrasound (VH IVUS) in 50 patients. The Agatston score on MSCT correlated moderately with calcium volume measured by VH IVUS, and MSCT plaque categories broadly reflected differences…

This in vitro study reports that shortwave (MHz-range) RF exposure can induce strong cytotoxicity in EGFR-overexpressing human cancer cells when those cells have internalized cetuximab-targeted gold nanoparticles. Control nanoparticles showed minimal uptake and substantially lower cytotoxicity under RF exposure. An…

This review describes proposed mechanical causes of drug-eluting stent thrombosis and notes that many are identifiable by greyscale intravascular ultrasound (IVUS). It highlights that evidence linking specific IVUS findings to stent thrombosis remains uncertain because relatively few stent thrombosis cases have been…

This Level III therapeutic case-control study evaluated shoulder capsule histology after arthroscopic thermal capsulorrhaphy using monopolar radiofrequency energy, with follow-up from 3.5 to 62 months. Mid- and long-term mRFE groups did not differ from controls on several histologic categories (synovial layer, edema,…

This retrospective case series reviewed four resections of symptomatic giant cavernous hepatic hemangiomas using an RF-powered multiarray (Habib sealer) for hepatic parenchymal transection. No blood transfusions were required and no major biliary or vascular injuries were observed at 1-year follow-up; one…

This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…
