F-Fluorodeoxyglucose positron emission tomography (FDG-PET) imaging can reveal hypometabolic regions during the interval between seizures in patients with epilepsy. However, visual-based qualitative analysis is time-consuming and strongly influenced by physician experience.

Postoperative Spindle Cell Nodule Mimicking Metastatic Lesion With Persistently Increasing 68 Ga-FAPI-04 Uptake After Receiving Personalized Antigen Peptide Tumor Vaccine.

A 59-year-old woman underwent radical surgery and chemotherapy for gastric adenocarcinoma. After the personalized antigen peptide tumor vaccine, a new nodular lesion, in the upper abdomen, was discovered during 68 Ga-FAPI-04 PET/MRI follow-up. To determine possible pseudoprogression, 68 Ga-FAPI-04 PET/MRI was repeated 39 days later, referring to immune PET response criteria in solid tumors.

Whole-brain glucose metabolic pattern differentiates minimally conscious state from unresponsive wakefulness syndrome.

Aims: The patient being minimally conscious state (MCS) may benefit from wake-up interventions aimed at improving quality of life and have a higher probability of recovering higher level of consciousness compared to patients with the unresponsive wakefulness syndrome (UWS). However, differentiation of the MCS and UWS poses challenge in clinical practice. This study aimed to explore glucose metabolic pattern (GMP) obtained from F-labeled-fluorodeoxyglucose positron emission tomography (F-FDG-PET) in distinguishing between UWS and MCS.
