Acute Findings on FDG PET/CT: Key Imaging Features and How to ...
Patient history, concurrent CT finding, and knowledge of typical patterns of metastatic spread can guide interpretation of the abnormal FDG uptake. 18 F-FDG, a glucose analogue, has been used for the detection and evaluation of a wide range of solid and hematological malignancies due to the increased rate of glucose utilization in cancer cells.
How We Read Oncologic FDG PET/CT - Cancer Imaging
2016年10月18日 · This patient presented with suspected metastatic nasopharyngeal cancer. Initial workup with endoscopic ultrasound and biopsy of the subcarinal node was non-diagnostic with necrotic tissue. FDG PET/CT demonstrates very intense uptake at all sites with lower uptake in the subcarinal node, only evident when widening the PET window.
FDG-PET/CT findings of a metastatic pituitary tumor - PMC
The authors report the fluorodeoxyglucose (FDG)-positron emission tomography(PET)/computed tomography (CT) findings of a rare case of growth hormone-secreting pituitary carcinoma with multiple metastatic lesions to the skeleton.
PET/CT for Patients With Breast Cancer: Where Is the Clinical …
2019年5月7日 · Patients with locoregional breast malignancy have 5-year survival rates of 76–99%, but for those with distant metastases, this rate decreases to 20–28% [2]. Mammography, ultrasound, and breast MRI help accurately stage local disease extent, whereas bone scan, abdominal CT or MRI, chest CT, and FDG PET/CT play a role in systemic staging.
Detection of distant metastatic disease by positron emission …
Distant metastatic disease detected by FDG-PET is found in 6.2% of patients with cervical cancer at the time of initial diagnosis and the most common site of disease is the lung. Further prospective investigation is warranted to delineate best treatment practices for cervical cancer patients presenting with distant metastases.
Clinical application of 18F-fluorodeoxyglucose positron emission ...
2013年3月26日 · The FDG-PET has been proven to be highly sensitive in detecting hepatic metastases from different primaries. Delbeke et al. studied the diagnostic value of FDG-PET in hepatic metastases measuring 1 cm and more and detected all 66 metastatic lesions originating from various primaries, such as the colon, pancreas, esophagus, sarcoma, and parotid.
Dynamic FDG-PET imaging for differentiating metastatic from …
2022年11月10日 · In the present study, we compared 18 F-FDG PET/CT dynamic imaging with static imaging and investigated the value of their metabolic parameters in the differential diagnosis between metastatic and non-metastatic FDG-avid LNs, especially in …
FDG PET/CT–based Response Assessment in Malignancies
2023年3月30日 · Functional imaging with 2- [fluorine 18]fluoro-2-deoxy-d-glucose (FDG) PET/CT has a vital role in the evaluation of several malignancies. FDG is a radioactive analog of glucose and follows the initial steps of glucose transport and phosphorylation.
A role of FDG-PET/CT for response evaluation in metastatic breast ...
2022年9月1日 · FDG-PET/CT has proven high prognostic values in patients with metastatic breast cancer when using quantitative PET methods. It has also shown a higher predictive value than conventional CT when applying the respective …
18F-FDG PET/CT and Melanoma: Staging, Immune Modulation …
2015年7月23日 · The usefulness of FDG PET/CT for imaging bone, soft-tissue, and visceral melanoma metastases has been well established, and in most instances, 18 F-FDG PET/CT outperforms conventional morphologic imaging modalities, such as CT alone or MRI, in depicting metastatic foci [14–16].
