Technetium Tc99m-tetrofosmin brain single-photon emission CT for the diagnosis of malignant meningiomas.
Emission CT for the Diagnosis of Malignant Meningiomas We read with great interest a recent article by Nagar et al in the American Journal of Neuroradiology investigating the usefulness of diffusion-weighted MR imaging in differentiating atypical/malignant meningiomas from benign meningiomas and detecting histologic dedifferentiation to higher tumor grade. The authors studied 48 cases of mening...

for the Assessment of Glioma Proliferation We read the interesting recent article by Kato et al concerning the assessment of glioma metabolic activity by positron-emission tomography (PET). The authors evaluated the type, grade, and proliferation index of 95 primary glioma cases by simultaneous [F] fluorodeoxyglucose (18F-FDG), C-methionine (MET) and C-choline (CHO) PET. Their results in astroc...
متن کامل18F-FDG PET/CT usefulness vs Tc99m-Tetrofosmin in the assessment of malignant brain gliomas: Report of two cases
Gliomas account for almost 80% of primary malignant brain tumors in adults. Magnetic Resonance imaging (MRI) is still the gold standard for diagnosis of brain tumors and brain 99mTc-tetrofosmin Single Photon Emission Computed Tomography (99mTc-tetrofosmin-SPECT) has been established as a useful tool for their evaluation. Fluorine-18–2-fluoro-2-deoxy-d-glucose positron emi...
متن کاملLong-term prognostic value of exercise technetium-99m tetrofosmin myocardial perfusion single-photon emission computed tomography
BACKGROUND Exercise (99m)Tc-tetrofosmin single-photon emission computed tomography (SPECT) is a useful tool for short- and medium-term risk stratifications. Currently, the long-term prognostic application of this technique has not been evaluated. METHODS AND RESULTS Exercise (99m)Tc-tetrofosmin was performed in 655 consecutive patients. Ten patients who underwent revascularization <60 days af...
متن کاملBrain single-photon emission CT physics principles.
The basic principles of scintigraphy are reviewed and extended to 3D imaging. Single-photon emission computed tomography (SPECT) is a sensitive and specific 3D technique to monitor in vivo functional processes in both clinical and preclinical studies. SPECT/CT systems are becoming increasingly common and can provide accurately registered anatomic information as well. In general, SPECT is affect...
