Optical imaging of lymph nodes.

Optical imaging or near infrared fluorescence (NIRF) imaging using enzymatically activatable smart probes is an exiting new imaging modality that can also be used for lymph node visualization and detection. This review intends to briefly summarize general aspects of optical imaging and its capabilities for lymph node imaging.

Diagnostic value of CT enteroclysis compared with conventional enteroclysis in patients with Crohn's disease.

Objective: The objective of our study was to assess the diagnostic value of CT enteroclysis compared with conventional enteroclysis in patients with Crohn's disease.

Subjects And Methods: Fifty consecutive patients (26 women, 24 men; mean age, 36.3 years; age range, 18-52 years) with histologically proven Crohn's disease underwent CT enteroclysis and conventional enteroclysis (median time interval, 21.

Imaging of advanced neuroendocrine tumors with (18)F-FDOPA PET.

Unlabelled: Nuclear medicine plays an important role in the imaging of neuroendocrine tumors (NETs). Somatostatin receptor scintigraphy (SRS) with (111)In-labeled somatostatin receptor analogs is a standard procedure for the detection and staging of NET. Based on the ability of NETs to store biogenic amines, this study evaluated whether 6-(18)F-fluoro-L-DOPA ((18)F-FDOPA) is a suitable PET tracer for NETs.
