Protocol Number: 07-M-0208

Title:

PET Imaging of Peripheral Benzodiazepine Receptors in Patients with Neurocysticercosis Using [C-11]PBR28

Number:

07-M-0208

Summary:

The purpose of this protocol is to measure peripheral benzodiazepine receptors in the brain using positron emission tomography (PET) and compare the imaging results between patients and healthy people.

Gender: Male & Female

Referral Letter Required: No

Population Exclusion(s): Children

Eligibility Criteria:

INCLUSION CRITERIA:

COMMON TO PATIENTS WITH NEUROCYSTICERCOSIS AND HEALTHY SUBJECTS:

Ages between 18 and 65, inclusive.

Patients must meet the inclusion criteria of protocol 85-I-0127.

CONTROL SUBJECTS:

Are healthy based on history, physical exams, ECG, and lab tests.

EXCLUSION CRITERIA:

COMMON TO ALL SUBJECTS:
