Abstract:

Pachygyria or incomplete lissencephaly is a developmental condition due to abnormal migration of neurons. The association of seizures in this condition warrants investigation like electroencephalogram (EEG) and magnetic resonance imaging (MRI). 18F-flurodeoxyglucose positron emission topography computed topography (18F-FDG PET/CT) has a potential role in commenting of wide distribution of abnormal metabolism in affected brain parenchyma as well as hypermetabolic epileptogenic focus during ictal phase. Scan during interictal phase will give an idea of affected regions in brain in the form of hypometabolic areas. Although treatment is long-term antiepileptic drugs however if the epileptogenic foci are localized to same region then surgical interventions like hemispherectomies are the options. We present a case in which 18F-FDG PET/CT proved beneficial in pachygyria with seizure disorder.

FDG PETCT in colorectal cancer

Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...

Underestimated role of 18F-FDG PET for HCC evaluation and promise of 18F-FDG PET/MR imaging in this setting.

TO THE EDITOR: We read with great interest the recent article by Cheung et al. on the utility of 11C-acetate/18F-FDG PET/CT for clinical staging and appropriate selection of patients with hepatocellular carcinoma (HCC) for liver transplantation based on the Milan criteria (1). The authors of this study were able to show the strength of PET/CT over dynamic contrast-enhanced CT to detect HCCs (pa...

[18F]FLT-PET and [18F]FDG-PET in the evaluation of radiotherapy for laryngeal cancer.

The evaluation of response to radiotherapy in patients with laryngeal cancer is a challenge because of the difficulty to differentiate between post-therapy changes and recurrent or residual tumor. Positron emission tomography is a non-invasive imaging tool that may be helpful in this differentiation. In this study, [(18)F]-fluoro-3'-deoxy-L-thymidine ([(18)F]FLT), a proliferation tracer is comp...
