Monitoring response to gefitinib in nude mouse tumor xenografts by 18 F-FDG microPET-CT: correlation between 18 F-FDG uptake and pathological response

Monitoring response to gefitinib in nude mouse tumor xenografts by 18 F-FDG microPET-CT: correlation between 18 F-FDG uptake and pathological response

BACKGROUND The purpose of this study is to investigate whether (18)F-fluorodeoxyglucose (FDG) micro-positron emission tomography-computed tomography (microPET-CT) can be used to monitor a metabolic response to gefitinib in nude mouse tumor xenografts. METHODS Sixteen nude mice were implanted with human A431 epidermoid carcinoma cells and ten with human A549 lung adenocarcinoma cells, and the ...

Detection of chordoma recurrence by F-18 FDG-PET/CT

Background: Despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. To our knowledge there are only very few reported cases of this rare tumor detected by F-18 FDG-PET. Materials and Methods: In this case we show the significanc...

F-18 FDG uptake in transplanted heart.

Cladellas et al. concern patients who failed to achieve an adequate heart rate response; it is not clear whether heart rate decrease occurred in any patient. As we reported, only 1 of 14 patients with paradoxical sinus deceleration was taking beta-blockers. We mentioned in our report that all our patients fasted for at least 3 h before dobutamine stress echocardiography; mild hypovolemia may ha...
