Dear CT Insider,
Radiologists who perform CT lung screening know the difficulty of distinguishing benign from malignant lung nodules. CT features such as large size, irregular shape, and spiculated margins can be convincing, but only biopsy or surgery can definitively answer the cancer question, especially when a nodule's appearance is indeterminate.
Dutch researchers are hoping to add another suspicious nodule feature to the list: CT attenuation. Using data from the Dutch-Belgian multicenter NELSON screening trial, they evaluated solid nodules in a screening population, automatically measuring CT values over a year's time. Check out our CT Insider Exclusive to see what they found.
In another lung cancer screening program, Canadian researchers aim to expand the knowledge base regarding the development of mesothelioma and other lung cancers in workers with long-term exposure to asbestos.
In liver imaging, CT still has the edge over MRI in evaluating potential living donors for transplant, say researchers from Essen, Germany. The group is still hoping to switch modalities when MR contrast agents improve.
Cardiac CT is making news with the first series evaluating 320-slice CT angiography. The images are crisp and the doses low considering that it was a first run, according to a team from Brigham and Women's Hospital in Boston.
