Additional diagnostic value of hybrid SPECT-CT systems imaging in patients with differentiated thyroid cancer.

Aim: : Nuclear medicine has entered a new era of multimodality imaging. Single-photon emission computed tomography/computed tomography (SPECT/CT) hybrid cameras are relatively new diagnostic tools that have been widely adopted and are present in most nuclear medicine units. SPECT/CT instruments allow functional and morphologic images to be acquired as superimposed (fusion images) in a single session.

Nuclear Medicine in Early-Stage Melanoma: Sentinel Node Biopsy-FDG-PET/CT.

Sentinel node status is the most powerful prognostic factor in patients with early-stage melanoma. This review discusses several issues of clinical interest and technical points for an optimized sentinel node biopsy (SNB) procedure. The role of fluorodeoxyglucose positron emission tomography/computed tomography is clearly established in patients with suspicion of locoregional or distant recurrence of melanoma before any surgical decision.
