Hormone replacement therapy complicates breast imaging
More than 470 million women worldwide are over age 50, according to the North American Menopause Society, and it's a safe bet that many of them are already on hormone replacement therapy (HRT). For imaging specialists, HRT can pose a range of imaging dilemmas.

MR tracks effects of herbal treatment for prostate cancer
As more prostate cancer patients turn to the dietary supplement PC-SPES, the herbal therapy is beginning to have implications for medical imaging. An international group hailing from California, New York, and Hannover, Germany studied the supplement's effects on prostate cancer using MRI and MR spectroscopy imaging (MRSI).

CT over the rainbow: color-coding protocol reduces errors
Colors play a major role in dictating human behavior. Red means stop, green means go, and orange means a detector configuration of 5 mm, slice thickness of 5 mm, and 1.5 ml/kg of contrast agent. It does, that is, if you are following "Rainbow Radiology," a color-coded system designed to streamline pediatric CT scans.

Unsuspected x-ray findings merit a second look for lung cancer
SAN FRANCISCO - Imaging has always been part of the standard protocol for patients with pulmonary disorders at the Portland VA Medical Center in Oregon, but radiographs sometimes revealed unsuspected clinical findings. The pulmonary specialists at the VA center developed a program that would follow up on these findings and possibly catch cancers earlier.

Multiple RTOG studies highlight advances in radiation therapy
Escalating radiation dosages in 3-D conformal therapy do not correspond with increasing late toxicity in prostate cancer patients, according to a study by the Radiation Therapy Oncology Group. Other studies looked at promising treatment protocols for brain tumors, lung cancer, and head and neck cancer.

FDG-PET measures soft tissue sarcoma response to chemotherapy
SAN FRANCISCO - Assessing how much viable tumor remains after neoadjuvant therapy may be the best way to gauge treatment response. When it comes to soft tissue sarcoma, figuring out which patients will benefit from neoadjuvant therapy is an ongoing problem. Preoperative imaging with FDG-PET may offer a solution.

FDG-PET improves prognosis of esophageal cancer patients
SAN FRANCISCO - FDG-PET can pinpoint distant esophageal metastases and potentially increase long-term survival after induction therapy, but whether it can alter the course of cancer treatment has yet to be determined. These are the conclusions reached by two groups of researchers at the American Society of Clinical Oncology meeting on Monday.
