Thyroid metastases yield to new radiotherapy approach
February 21, 2000 -- A new study in the treatment of unresectable or metastatic medullary thyroid cancers shows promising initial results with high-dose radioimmunotherapy of cancer sites with anti-carcinoembryonic antigen monoclonal antibodies.
Cutting catheter matches surgery in ureteral stenoses
February 18, 2000 -- Treating stenotic uroenteric anastomoses with a cutting balloon catheter rather than traditional endoscopic surgery saves time and manpower during the procedure, according to a newly published French study.
Doppler index identifies cancer recurrence risk
February 17, 2000 -- Many patients who undergo colorectal cancer surgery have occult liver metastases that correlate to an increased likelihood of recurrent disease, so Scottish researchers are looking at Doppler perfusion values to identify those at risk.
Can the utility of V/Q scans for embolism be improved?
February 16, 2000 -- While many researchers are looking at CT angiography for suspected pulmonary embolism, a new position paper advocates recategorizing some of the indeterminate findings on ventilation-perfusion scans.
Update on interventions for malignant liver tumors
February 15, 2000 -- Wider application of percutaneous ultrasound- and MR-guided ablation techniques promise to markedly increase the role of the interventional radiologist in the treatment of limited hepatic tumors.
Siemens raises ante in MRI's superconducting open segment
February 14, 2000 -- MRI vendors have begun to push the envelope of superconducting technology in their quest to commercialize new scanners that offer the convenience of open design with the image quality of supercon magnets.
Virtual bronchoscopy edges toward reality
February 11, 2000 -- Researchers have combined CT imaging with navigational concepts borrowed from bronchoscopy to create virtual bronchoscopy, a noninvasive guided imaging technique that enables a sort of virtual fantastic voyage through a patient's airways.
Earlier cancer detection sought in breast duct lavage
February 10, 2000 -- By identifying the microscopic cellular changes that occur inside the milk ducts, surgeons at Vanderbilt University are hoping to find a way to detect breast cancer very early in its development.
