C Cohade, M Osman, J Leal… - Journal of Nuclear …, 2003 - Soc Nuclear Med
The purpose of this study was to compare 18 F-FDG PET and PET/CT in a population of
patients with colorectal cancer. Methods: PET and PET/CT images from 45 patients (17 women, …

Normal FDG distribution patterns in the head and neck: PET/CT evaluation

…, M Tatsumi, D Hammoud, C Cohade, MM Osman… - Radiology, 2005 - pubs.rsna.org
PURPOSE: To retrospectively evaluate the distribution of fluorine 18 fluorodeoxyglucose (FDG)
in the head and neck region with combined positron emission tomography–computed …

Respiratory motion artifacts on PET emission images obtained using CT attenuation correction on PET-CT

MM Osman, C Cohade, Y Nakamoto… - European journal of …, 2003 - Springer
PET-CT scanners allow generation of transmission maps from CT. The use of CT attenuation
correction (CTAC) instead of germanium-68 attenuation correction (Ge AC) might be …

[PDF][PDF] Phase I single-dose study of intracavitary-administered iodine-131-TM-601 in adults with recurrent high-grade glioma

…, MB Khazaeli, D Colcher, A Liu, M Osman… - Journal of Clinical …, 2006 - academia.edu
Purpose TM-601 binds to malignant brain tumor cells with high affinity and does not seem to
bind to normal brain tissue. Preclinical studies suggest that iodine-131 (131I)–TM-601 may …

Clinically significant inaccurate localization of lesions with PET/CT: frequency in 300 patients

MM Osman, C Cohade, Y Nakamoto… - Journal of Nuclear …, 2003 - Soc Nuclear Med
This study evaluated lesion mislocalization between PET and CT on PET/CT studies when
CT instead of germanium is used for attenuation correction (AC). Methods: PET/CT scans …

PET/CT: comparison of quantitative tracer uptake between germanium and CT transmission attenuation-corrected images

Y Nakamoto, M Osman, C Cohade… - Journal of Nuclear …, 2002 - Soc Nuclear Med
In PET, transmission scanning for attenuation correction has most commonly been performed
with an external positron-emitting radionuclide source, such as 68 Ge. More recently, …
