Active Comparator: 1- Healthy Subjects
Healthy Subjects- receive MRA
Procedure: Magnetic Resonance Angiography (MRA)
As part of the Magnetic Resonance(MR) scan, you will need to lie still on a padded MR table inside the MR machine for about 15 minutes at a time while MR studies are being performed on you. The total time for the clinical portion of the MR study is approximately 35-40 minutes and there will be an additional 30 minutes for the research related MR studies. The total time you will spend on the MR table for this research will seldom be more than one hour.

Active Comparator: 2 - patients with SLE, no neuropsych
Systemic Lupus Erythematosus(SLE) patients without neuropsychiatric symptoms - receive MRA
Procedure: Magnetic resonance imaging
Other Name: MRAProcedure: MRA
MRA of the brain
Active Comparator: 3 - patients with SLE with neuropsych
20 symptomatic neuropsychiatric systemic lupus erythematosus(NPSLE) patients.
Procedure: diffusion Imaging
MRA of the Brain
Active Comparator: 4- healthy patients from other cohort
10 Healthy Controls (HC) from an existing cohort as part of another sponsored study.
Procedure: perfusion imaging.
MRA of the brain
Purpose of the Study:
We plan with this study to obtain pilot data to support a larger grant application which will evaluate whether any of three types of functional Magnetic Resonance Imaging (known as MR Spectroscopy [MRS], MR Perfusion Imaging, and MR Diffusion Tensor Imaging [DTI]) can detect alterations in brain function distinctive for Neuropsychiatric Systemic Lupus Erythematosus (NPSLE), Systemic Lupus Erythematosus (SLE), and compare our findings to those found in an existing cohort of 20 normal healthy controls. Because this study is being done on a 3T(tesla)scanner (3T(tesla) Achieva(Model name), Philips Medical Systems) and our previous group of healthy controls was assessed using a 1.5 T(tesla) scanner (LX EchoSpeed, General Electric(GE) Medical Systems), we propose to re-consent 10 of the previous 20 healthy controls and re-collect imaging data on the 3T(tesla) scanner in order to confirm that our previously-collected data from the group of 20 healthy controls is still valid. This will confirm that the change of field strength and manufacturer does not affect data validity.
Recruiting Update as of March/2009: Enrollment is completed for Study Arms 1 and 2.
