2023年8月28日 · Fludeoxyglucose F18 (FDG) is a positron-emitting radiotracer used with positron emission tomography (PET) to diagnose and monitor various conditions. Standard imaging modalities such as X-ray, CT, and MRI allow great detail visualization of …

2016年6月18日 · One hundred eighty three adult scans were evaluated (95 men, 88 women). The mean patient-specific effective dose from a mean injected 18F-FDG activity of 450 ± 32 MBq was 9.0 ± 1.6 mSv. For all standard PET/CT patients, mean effective mAs was 39 ± 11 mAs, mean CT effective dose was 5.0 ± 1.0 mSv and mean total effective dose was 14 ± 1.3 mSv.

For an administered activity of 370 MBq of 18 FDG, the effective dose from PET/CT investigations was estimated to be 14.2 mSv in males and 17.2 mSv in females. Interpretation & conclusions: The present results did not demonstrate significant …

2025年3月1日 · This study aims to assess the lower limit in administered activity of 2-deoxy-2-[18 F]fluoro-D-glucose ([18 F]FDG) and/or scan time reduction capabilities for the Omni Legend PET/CT while being compliant with current and updated European Association of Nuclear Medicine (EANM) Research Ltd Fluorine-18 accreditation specifications (EARL 1 and ...

2004年10月1日 · Tumor uptake reached 2.65% dose [18 F]FDG/g at 60 min and remained relatively constant until 120 min. Blood clearance [18 F]FDG was very rapid, and tumor/blood ratios reached 22.1 at 60 min. Tumor/tissue ratios were very high in most organs, especially in the liver, kidneys, and pancreas.

2023年5月5日 · 18 F-FDG can cause radiation harm to both work in the radiation field and attendants; for the public, an individual is exposed just one time unlikely to be exposed more than once; in fact, the overall dose received by others is mostly affected by the effective half-life of radionuclide, length of contact time with the patient, and distance from ...

acquiring 18F-fluorodeoxyglucose (FDG) PET/CT scans in adults? Answer: There is no uniformly agreed upon method for deter-mining optimal FDG administra-tion activity. The generally accepted range of activities used in adult FDG PET/ CT imaging is 4 to 20 mCi. The Society of Nuclear Medicine and Molecular Imaging (SNMMI) has provided guidance ...

The total effective dose from a typical protocol of whole body PET/CT examination was 14.4 mSv for females and 11.8 mSv for male patients from (18)F-FDG, whereas it was 11 mSv for female and 9.1 mSv for male patients from (18)F-FDOPA.

The International Myeloma Working Group consensus aimed to provide recommendations for the optimal use of 18 fluorodeoxyglucose (18 F-FDG) PET/CT in patients with multiple myeloma and other plasma cell disorders, including smouldering multiple myeloma and solitary plasmacytoma. 18 F-FDG PET/CT can be considered a valuable tool for the work-up of...

2017年4月1日 · 18 F-FDG PET/CT can be coupled with sensitive bone marrow-based techniques to detect minimal residual disease (MRD) inside and outside the bone marrow, helping to identify those patients who are defined as having imaging MRD negativity.
