A British study confirms the high sensitivity and specificity of PET/CT in identifying focal bony disease in patients with Hodgkin’s disease, according to research presented at the recent 2008 RSNA meeting. The research further suggests that the imaging modality can play an important role in initial staging of the disease.

A study from the Cleveland Clinic to investigate brain metabolism of patients with amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) has shown that PET imaging may be useful in distinguishing typical dementia syndromes, such as Alzheimer’s disease and frontotemporal dementia, from atypical cortical changes.

Clinical research has begun to suggest that fluorine-18 (F-18) FDG-PET and contrast-enhanced breast MRI can be powerful tools for diagnosis and treatment staging in women with suspected breast malignancy. But FDG-PET for these patients is limited by its variable sensitivity — certain types of breast cancer have abnormally low FDG uptake. One solution is to [...]

Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or map of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Images of tracer concentration in 3-dimensional space [...]
