68Ga-citrate PET/MR Imaging for Glioma

Terminated
Conditions
Glioma
Interventions
Drug: 68Ga-citrate PET/MR
Registration Number
NCT03335280
Lead Sponsor
Susan Chang
Brief Summary

This is a prospective, single center, open-label study in adult patients with presumed World Health Organization (WHO) grade 3 or 4 glioma who will be undergoing surgical resection as standard of care. In some cases, patients will have had biopsy. Study participants will undergo 68Ga-citrate Positron Emission Tomography / magnetic resonance (PET/MR) prior to surgery.

Primary Outcome Measures
NameTimeMethod
Maximum standardized uptake value (SUVmax)1 day

The location and extent of 68Ga-citrate uptake will be compared to both same day magnetic resonance imaging (MRI) and subsequent pathology. SUVmax will be the outcome of interest and summarized with descriptive measures. SUVmax will be compared via a two-sided two-sample equal-variance t-test between those patients positive for PTEN deletion and those negative for PTEN deletion.
