Late phase best to differentiate focal liver lesions with CEUS
By N. Shivapriya
Differentiating benign from malignant lesions with contrast-enhanced ultrasound (CEUS) is best done at late phase, and a quantitative analysis of ultrasound video intensity can be used to calculate the conspicuity index for effective and objective differentiation of the liver tumors, according to Italian researchers.

By Jerry Ingram
FDG-PET appears to be more effective, accurate, and cost-effective than MRI for detecting high-grade and distant lesions in soft-tissue sarcomas. But the extra cost may not be warranted when it comes to detecting local lesions, according to researchers from Korea.

FDG-PET/CT tops other technologies for lymphoma staging
By Jonathan S. Batchelor
ORLANDO, FL - Correctly staging and restaging lymphoma, both Hodgkin's and non-Hodgkin's, is crucial for patient management. Researchers from Stanford University Medical Center in Stanford, CA, evaluated patients with biopsy-proven lymphoma and found FDG-PET/CT to be superior to other modalities for staging, restaging, and anatomic localization.

Panoply of VC studies yields significant extracolonic findings
By Eric Barnes
A meta-analysis of VC studies has enumerated what radiologists have been noticing for years: that VC reveals important incidental abnormalities. The findings deemed "important" ranged from abdominal aortic aneurysms to early extracolonic cancers -- the latter detected at rates equivalent to that of breast cancer screening. The U.K. authors could only conclude that VC may become an important method of detecting early extracolonic cancers.

However, a research team in Ireland used the five-step process of evidence-based medicine to successfully implement new protocols for CCLM that utilize PET as the primary imaging modality.

CT screening detects early lung cancers, but mortality benefits unclear
By N. Shivapriya
CT screening of high-risk patients detects many smaller early stage lung cancers, according to a study by Mayo Clinic researchers. But the data does not suggest a mortality benefit, and it is also unclear if the findings represent a true stage shift, the group concluded after a five-year prospective study of 1,520 current and former smokers, both men and women.
