Ultrasound-Guidance Used to Insert Peritoneal Dialysis Catheters Considerably Cuts Complications

Patients undergoing peritoneal dialysis catheter placement using fluoroscopy and ultrasound-guidance experienced significantly fewer complications at one year postinsertion than did patients whose catheters were positioned laparoscopically.   More...

Axial T1-weighted contrast-enhanced MR images demonstrating a right ischial metastasis (black arrow) before treatment (left) and immediately after magnetic resonance-guided focused ultrasound surgery (MRgFUS) treatment (right). The post-treatment image shows nonenhancement of the lesion, which was targeted from a posterior approach. Each hash mark on the scale bars represents 1 cm (Photo courtesy of Journal of the US National Cancer Institute (JNCI)).

Focused Ultrasound Can Lessen Cancer Pain

A new phase III clinical trial shows that noninvasive magnetic resonance-guided focused ultrasound treatment that heats the cancer within the bone relieves pain and improves function for most patients when other treatment alternatives are limited.  More...

Image: Ultrasound imaging used to identify breast cancer in underarm lymph nodes in obese women has generated an unexpected finding: Fat did not obscure the images, and ultrasound imaging showing no suspicious lymph nodes actually was shown to be more accurate in overweight and obese patients than in women with a normal body mass index (Photo courtesy of the Mayo Clinic).

Lymph Node Ultrasound Imaging Most Effective for Obese Breast Cancer Patients

New research into whether ultrasound imaging used to identify breast cancer in underarm lymph nodes is less effective in obese women, has generated an unexpected finding.  More...

Hepatocellular Carcinoma Screening Linked with Curative Treatment and Longer Survival in Cirrhosis Patients

Investigators discovered that patients with cirrhosis who underwent surveillance for hepatocellular carcinoma had cancers detected at an earlier stage, were more likely to receive curative instead of palliative treatment, and had longer survival.   More...
