The tPO2 of occluded segments first group: Evaluation of hypoxia in an experimental rat tumour model by [ 18 F]fluoromisonidazole PET and immunohistochemistry.
The fractional concentration of inspired oxygen FiO2 was set to 0.
They determined the activity of [18F]FMISO in relation to the hepatic oxygen availability and the partial pressure of oxygen in tissue tPO2 to define a critical oxygen delivery on a regional basis. The radiobiologically hypoxic fraction determined for tumors in air-breathing rats during imaging was 6.
Determining hypoxic fraction in a rat glioma by uptake of radiolabeled fluoromisonidazole. Results showed a significant decrease of DO2 in occluded liver tissue samples first group: Quantifying regional hypoxia in human tumors with positron emission tomography of [18F]fluoromisonidazole: SUVs and ratios-to-reference tissues mediastinum or muscle were calculated.
Characterization of [18F]fluoroetanidazole, a new radiopharmaceutical for detecting tumor hypoxia. An appraisal of radiotherapeutically relevant hypoxia. This is the reason for the multitude of efforts to develop methods and imaging techniques for measuring oxygen in tissues.

This study aimed to develop an automated synthesis of [18 F]fluoromisonidazole ([18 F]FMISO) using a Scanditronix Anatech RB III robotic system.
[ 18 F]HF was produced via the 18 O(p,n) 18 F reaction using a Scanditronix MC17F cyclotron. An efficient preparation of the hypoxic cell tracer [18 F]3-fluoro(2′-nitro-1′-imidazolyl)propanol ([18 F]fluoromisonidazole) is reported.
This radiopharmaceutical is of interest to probe hypoxic tissue in infarcts and tumors. BASICSCIENCES Anewpreparationof[18F]fluoromisonidazole[1H(3-[18F]fluorohydroxypropyl)nitroimidazole]ispresentedasatwo-step,two-potreactionsequence.
