Breakthroughs - Summer 2008


Stereotactic Radiosurgery

BrainThe Gamma Knife radiosurgery system uses targeted beams of radiation to treat brain tumors and abnormalities with surgical precision but no incision. The latest upgrade to the device – in use since April – offers reduced treatment times and the ability to deliver radiation to a broader area, including tumors in the skull base.


3-D Biopsy System

A preliminary study led by Washington University urologists at the Siteman Cancer Center shows this new ultrasound technology increases the accuracy of prostate biopsy. A stationary probe improves patient comfort and – for the first time – provides 3-D images of the prostate gland. It also guides surgeons in obtaining tissue samples from all areas of the gland.

O-Arm Scanner

Rather than using a traditional X-ray with a postoperative CT scan, surgeons can now view the surgical progress on spine patients during procedures using new diagnostic technology. A mobile 3-D scanner called an O-arm allows for adjustments during a procedure, which can reduce the need for a second surgery.

Understanding Brain Tumors

While Senator Ted Kennedy was recently diagnosed with a malignant brain tumor, a brain tumor diagnosis isn't necessarily a death sentence. New treatments and technologies are giving patients new hope. Find out more from Dr. Ralph Dacey, chief of neurosurgery at Barnes-Jewish Hospital and Washington University School of Medicine.
