FDG PET/CT outperforms biopsy for detection of malignancy in lymphoma

The gold standard for the detection of bone marrow invasion of diffuse large B-cell lymphoma is bone marrow biopsy. Researchers investigated a new approach with F-18 FDG PET/CT imaging to determine its efficacy and predictive value. The latter was found superior to biopsy in not only its sensitivity and accuracy, but also its ability to predict progression-free survival, according to a study published online May 14 in the Journal of Nuclear Medicine.

Zr-89 bevacizumab could be a player in PET detection of breast cancer

Breast cancer tumors often express vascular endothelial growth factor (VEGF)-A and a method of detection involving PET and the monoclonal antibody tracer Zr-89 bevacizumab is showing promise for the assessment of early to late stage primary malignancy, according to a study published May 7 in the Journal of Nuclear Medicine.

Calif. dose reporting law trades flexibility for ‘rote numeric compliance’

Radiation dose reporting regulation recently enacted in California, while well-intentioned, has the potential to subject radiologists to new and unvalidated standards, restrict necessary adjustments to imaging protocols and mislead patients, according to an article published online May 10 in the Journal of the American College of Radiology.
