Neuroendocrine tumours (NETs) of the head and neck are rare neoplasms and can be of epithelial or non-epithelial differentiation. Although the natural history of NETs is variable, it is crucial to establish an early diagnosis of these tumours as they can be potentially curable. Conventional anatomical imaging and functional imaging using radionuclide scintigraphy and positron emission tomography/computed tomography can be complementary for the diagnosis, staging and monitoring of treatment respo...

endoscopic ultrasound (EUS) and 2-[ 18 F]-fluoro-2-deoxy-Dglucose (FDG) positron-emission tomography/computed tomography (PET/CT), with just over 70% proceeding to treatment with curative intent (with surgical treatment in 45%). Several EUS and FDG PET/CT parameters were found to be inversely related to survival on univariate analysis, with the EUS-derived tumour volume (EDTV) and PET/CT N-stage being shown to be significantly and independently associated with survival. This study confirms that ...

Neuroendocrine tumours (NETs) are rare, heterogeneous, and often hormonally active neoplasms. Nuclear medicine (NM) imaging using single photon- and positron-emitting radiopharmaceuticals allows sensitive and highly specific molecular imaging of NETs, complementary to anatomy-based techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI). Somatostatin-receptor scintigraphy is a whole-body imaging technique widely used for diagnosis, staging and restaging of NETs. The inc...

AbstractBackground Many physicians do not consider thediagnosis of bile acid malabsorption in patients withchronic diarrhea, or do not have access to testing. Weexamined yield of 23-seleno-25-homo-tauro-cholicacid (SeHCAT) scanning in chronic diarrhea patients,and attempted to identify predictors of a positive test.Methods Consecutive patients with chronic diarrheaundergoing SeHCAT scan over a 7-year period wereidentified retrospectively. Bile acid malabsorption wasdefined as present at a retentio...

Aims To analyse the diagnostic accuracy of delayed response assessment 2-[18F]-fluoro-2-deoxy- d- glucose (FDG) positron-emission tomography–computed tomography (PET-CT) following (chemo)radiation for locally advanced head and neck squamous cell carcinoma (HNSCC). Material and methods Forty-four consecutive patients who underwent a baseline and response assessment using FDG PET-CT for HNSCC following (chemo)radiation between August 2008 and April 2011 were identified retrospectively. Clinicopath...

: The emergence of hybrid imaging, combining anatomical computed tomography (CT) and functional single-photon emission computed tomography (SPECT), has greatly expanded the armoury available to image disease. Integrated SPECT-CT is a dual-modality technique, which improves the sensitivity and specificity of existing radionuclide studies and enables characterization of equivocal findings detected by conventional imaging. There is a wide range of established and emerging clinical applications for ...
