An update on the role of F-FDG-PET/CT in major infectious and inflammatory diseases.

For decades, conventional nuclear medicine techniques have been utilized for the assessment of many infectious and inflammatory diseases. Most of these techniques have limitations such as the relatively low spatial resolution, being time consuming and low sensitivity or specificity. In recent years, FDG-PET/CT has shown promising role in the management of such diseases.

Pretreatment volumetric parameters of FDG-PET predict the survival after Yttrium-90 radio-embolization in metastatic liver disease.

This study aimed to determine the prognostic value of pretreatment FDG-PET in patients with metastatic liver disease undergoing Yttrium 90 (Y) radio-embolization using global disease assessment measures. Data from 16 patients with metastatic liver disease (8 males, 8 females) aged 55-97 years (mean: 67±12) were retrospectively collected. On PET, active malignant lesions in the liver were segmented with an adaptive thresholding system (ROVER software, ABX GmbH, Radeberg, Germany).
