Researchers find benefit for lymphoma patients in combined PET-CT scanning

Combined positron emission tomography (PET) and computed tomography (CT) imaging of lymphoma patients is a more effective method to evaluate response to radiation therapy, and may help patients avoid unnecessary follow-up treatments, a study by researchers at the University of Southern California (USC) suggests.

New imaging technique provides better view of Barrett's esophagus

Novel techniques to improve the quality of imaging are helping doctors get a better look at esophageal conditions such as Barrett's esophagus (BE), but they do not necessarily improve the diagnosis or physician agreement on images, according to a study published this month in Gastroenterology , the official journal of the American Gastroenterological Association (AGA) Institute.

PET/CT planning beneficial for head and neck cancer patients

Using a combination of positron emission tomography (PET) and computed tomography for radiation therapy treatment planning in head and neck carcinoma patients provides for excellent, local and regional disease control when compared to CT alone, according to a study in the March 1 issue of the International Journal for Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Arsenic aids tumor imaging when joined to cancer-homing drug

Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found.
