PET Scans in Normal Volunteers and Patients With Fabry Disease
(18)Fluorodeoxyglucose Positron Emission Tomography in Patients With Fabry Disease
This study will determine the rate of sugar metabolism in the brain of patients with Fabry disease, a genetic disease of abnormal lipid metabolism. Compared with healthy people, patients with Fabry disease have increased blood flow to the brain, which may result from abnormal brain metabolic activity. This study will use positron emission tomography (PET) and magnetic resonance imaging (MRI) to compare brain sugar metabolism in eight untreated patients, eight patients who are receiving enzyme replacement therapy, and eight healthy volunteers.
Patients with treated and untreated Fabry disease and normal volunteers may be eligible for this study. Participants will undergo the following two procedures:
- PET scan < The patient lies in the PET scanning machine. First, the chest is scanned for a few minutes to determine how much radiation the tissues of the chest absorb. A radioactive sugar called fluorodeoxyglucose (FDG) is then injected through a catheter (thin plastic tube placed in a vein) and the heart is scanned for about 45 minutes to measure the amount of FDG in the blood inside the heart. The head is then scanned for about 20 minutes to measure FDG in the brain. This measurement tells how much sugar the brain uses for energy. The procedure requires insertion of two or three catheters. A special facemask may be molded to the patient's head to help hold the head still during the scanning.
- MRI scan < The patient lies on a table surrounded by the scanner (a metal cylinder) for about 60 minutes. A strong magnetic field and radio waves are used to show images of structural and chemical changes in tissues.
This study may provide information that will help explain abnormalities in Fabry disease and the effect of treatment on the brain.
