PET SUV measurements vary between facilities
By Eric Barnes
For lung cancer patients undergoing chemotherapy and radiation, PET can be a good way to monitor and even predict treatment response. But the response measured in standardized uptake values (SUVs) can vary significantly depending on the facility in which SUV is measured.

MIP boosts detection of small pulmonary nodules
By Erik L. Ridley
CHICAGO - Performing maximum intensity projection (MIP) reformatting of MDCT studies adds significant utility for finding pulmonary nodules less than 10 mm in size, according to research from the University Medical Center Hamburg-Eppendorf in Hamburg, Germany.

Dual-energy CT helps distinguish PE from other perfusion defects
By Eric Barnes
CHICAGO - Detecting pulmonary perfusion defects at CT is considered good evidence for the presence of pulmonary embolism (PE), but not all perfusion defects represent PE. Dual-energy CT can distinguish non-PE causes of perfusion defects from the real thing, according to Korean researchers.

PET/CT finds some lesions chest CT cannot
By Wayne Forrest
CHICAGO - PET/CT showed its prowess over CT by detecting additional lesions in 23% of all cancer patients who had a conventional thoracic CT, according to a presentation at the 2008 RSNA meeting.

Radical robotic radiosurgery produces 'distinctive' PET/CT imaging pattern
By Wayne Forrest
CHICAGO - Researchers at Georgetown University Hospital in Washington, DC, have found that radical robotic radiosurgery results in a "distinctive PET/CT imaging pattern" following treatment, which likely is related to high radiation doses delivered 1 cm or more around the tumor.

Chest wall toxicity reported after high-dose lung SBRT
By Cynthia E. Keen
Stereotactic body radiation therapy (SBRT) is emerging as an effective treatment for peripheral non-small cell lung cancer, but not without chest wall toxicity for some patients. Rib fractures and severe chest wall pain can occur months after treatment.

Lung CAD holds up well in low-dose MDCT studies
By Erik L. Ridley
Computer-aided detection (CAD) technology offers comparable performance in low-dose and standard-dose MDCT chest studies, according to research published in the British Journal of Radiology. The research team from Germany retrospectively evaluated chest CT examinations of 77 patients for pulmonary nodules.

Nodule measurement streamlined with space-scale analysis
By Eric Barnes
Researchers from Florence, Italy, have developed a robust and accurate method of measuring most lung nodules, improving the odds that growing lesions can be detected at CT with greater accuracy and reproducibility compared to current methods that rely on prior segmentation of the CT data.

Proton therapy reduces bone marrow toxicity compared with IMRT
By Edward Susman
Tighter control of how much radiation is focused on a tumor and how much affects adjacent structures appears to result in less bone marrow toxicity among patients treated with proton beam therapy, when compared with conventional intensity-modulated radiation therapy (IMRT).
