Prisijungti Registracija
Fluorine-18 labelled fluoromisonidazole ([18F]FMISO) has been shown to accumulate in hypoxic tissue in inverse proportion to tissue oxygenation. In order to evaluate the potential of [18F]FMISO as a possible positron emission tomography (PET) tracer for imaging of liver tissue hypoxia, we measured

OBJECTIVE
To study the relation between SUVmax, hypoxia inducible factor 1α (HIF-1α), angiogenetic factor adrenomedullin (AM) and antiapoptotic factor Bcl-2 in endometrial cancer.
METHODS
Thirthy eight patients who were diagnosed after a preoperative endometrial biopsy with endometrium cancer

In vivo demonstration of hypoxia is of significance for tumour patient management. Fluorine-18 fluoromisonidazole ([18F]FMISO) is a proven hypoxic imaging agent. We developed an [18F]FMISO tumour to muscle retention ratio (TMRR) for the detection of tumour hypoxia in nasopharyngeal carcinoma (NPC).
In vivo delineation of myocardial hypoxia during coronary occlusion using fluorine-18 fluoromisonidazole and positron emission tomography: a potential approach for identification of jeopardized myocardium.

Previous studies have demonstrated that the positron-emitting fluorine-18 (18F)-labeled fluoromisonidazole is a specific tracer of myocardial hypoxia. Its fractional extraction is enhanced in ischemic or hypoxic myocardium but returns to baseline levels on reperfusion and recovery of normal
Correlation of hypoxia as measured by fluorine-18 fluoroerythronitroimidazole (18F-FETNIM) PET/CT and overall survival in glioma patients.

PURPOSE
Hypoxia is important in the biology of glioma in humans. Positron emission tomography/computed tomography (PET/CT) with a hypoxia tracer offers a noninvasive method to differentiate individual tumor biology and potentially modify treatment for patients with malignancies.Optimal timing of fluorine-18-fluoromisonidazole positron emission tomography/computed tomography for assessment of tumor hypoxia in patients with head and neck squamous cell carcinoma.
