Can full-dose contrast-enhanced CT be omitted from an FDG-PET/CT staging examination in newly diagnosed FDG-avid lymphoma?
Unenhanced low-dose FDG-PET/CT alone is suggested as the primary imaging modality of choice for staging patients with newly diagnosed FDG-avid lymphoma. This diagnostic approach is particularly indicated in younger patients in whom diagnostic radiation exposure should be minimized and in patients who are at increased risk of CT contrast-induced allergic reactions or nephropathy.
Enhanced fragmentation of SLRPs is evident in degenerate articular cartilage and meniscus. Specific decorin and fibromodulin core protein fragments in degenerate meniscus and/or human articular cartilage may be of value as biomarkers of disease. Once the enzymes responsible for their generation have been identified, further research may identify them as therapeutic targets.
