F-FDG-PET patterns of surgical success and failure in mesial temporal lobe epilepsy.

Objective: To search for [F]-fluorodeoxyglucose (FDG)-PET patterns predictive of long-term prognosis in surgery for drug-resistant mesial temporal lobe epilepsy (MTLE) due to hippocampal sclerosis (HS).

Methods: We analyzed metabolic data with [F]-FDG-PET in 97 patients with MTLE (53 female participants; age range 15-56 years) with unilateral HS (50 left) and compared the metabolic patterns, electroclinical features, and structural atrophy on MRI in patients with the best outcome after anteromesial temporal resection (Engel class IA, completely seizure-free) to those with a non-IA outcome, including suboptimal outcome and failure. Imaging processing was performed with statistical parametric mapping (SPM5).

Diagnostic value of combining ¹¹C-choline and ¹⁸F-FDG PET/CT in hepatocellular carcinoma.

Purpose: In this prospective study, our goal was to emphasize the diagnostic value of combining (11)C-choline and (18)F-FDG PET/CT for hepatocellular carcinoma (HCC) in patients with chronic liver disease.

Methods: Thirty-three consecutive patients were enrolled. All patients were suspected to have HCC based on CT and/or MRI imaging.
