Study proves catheter ablation safe for patients
...rves in patients undergoing catheter ablation with radiofrequency
energy. It was determined that no significant injury occurs to cardiac nerves as a result of ablation, and changes in heart rate during the procedure are transitory and are related primarily to medications and other procedural variables. Catheter ...

device that heats the lower layers of the skin, ThermaCool may tighten the skin and improve skin texture. In addition, it may dramatically improve the skin of patients with acute cystic acne. According to a study presented at Plastic Surgery 2004, p...
New research in atrial fibrillation
..., catheters (thin tubes) are put in the heart, and radiofrequency
energy is used to isolate the area that causes the fibrillation. "In patients who have simple AF -- that is, there is no other heart disease -- this technique is very effective. At the end of one year, 60 to 80 percent of patients are cured; they hav...

MRI 'excellent choice' for evaluating causes of abdominal and pelvic pain in pregnant women
...and CT scans, MRI uses a strong magnetic field and radiofrequency
pulses to produce images. Ionizing radiation is a known carcinogen, whereas magnetic fields and radiofrequency
pulses are not associated with cancer or fetal malformations," said Katherine R. Birchard, MD, of th...
Novel MRI technique provides clear images of blood flow
... the researchers rotated the scanner, adjusted the radiofrequency
of the scanner and developed a complex new way of capturing the images. "As the blood cell flows through the plane, it is excited by the MRI," Judd explained. "While the next cell is also excited when it flows through, the first cell still gives off ...
Minimally invasive breast cancer treatment shows promise
OAK BROOK, Ill. - A pilot study using radiofrequency
(RF) ablation to treat small breast cancers has found the procedure feasible and safe, according to an article appearing in the April issue of the journal Radiology. "This study has added another potential weapon to the breast cancer treatment arse...
