Modern nuclear imaging for paragangliomas: beyond SPECT.
Paragangliomas are rare neuroendocrine tumors that may arise anywhere along the paraganglial system, with a high frequency of hereditary forms or multifocal disease. Most often, paragangliomas are benign and progress slowly, but metastases may occur in about 10% of patients. In this respect, nuclear imaging in combination with anatomic imaging may be required to fully delineate the extent of th...
متن کاملModern PET imaging for paragangliomas: relation to genetic mutations.
AIM AND METHODS Paragangliomas (PGL) are neural crest-derived tumours that are found along the autonomic neural network throughout the body and can be multiple and/or metastatic. Nuclear medicine imaging in combination with conventional imaging is required to fully delineate the extent of the disease. The performance of molecular imaging modalities is widely dependent on tumour biology. RESUL...
متن کاملPET/SPECT: functional imaging beyond flow
In this review, first principles of positron emission tomography (PET) and single photon emission tomography (SPECT) are discussed together with the relative strengths and weaknesses of both techniques. With both modalities it is possible to image and, especially with PET, to measure regional tissue function, the particular function being interrogated depending on the actual tracer being used. ...
متن کاملThe effect of earth magnetic field on the function of nuclear medicine imaging systems (SPECT)
Background: The nuclear medicine systems are very sensitive to the variation of the magnetic field. Photomultiplier tubes amplify low energy light signal and change it into electrical current. Low magnetic field can produce some variations in uniformity and special resolution of SPECT systems. In this study, we tried to evaluate the effects of magnetic field on the function of nuclear medic...
متن کاملMR imaging of paragangliomas.
MR imaging of 15 paragangliomas in 10 patients was compared with CT of 13 of the lesions in eight patients. All lesions were confirmed with angiography. All lesions were detected by MR and CT with the exception of one small glomus tympanicum tumor that was seen only in retrospect with MR. CT better demonstrated subtle osseous changes of the skull base and the relation of the tumor to the middle...
