Primary Outcome Measures:
  • Measurement of Tophi by MRI - Difference in Volument Between Visits [ Time Frame: Visit 1 (Day 1) and Visit 2 (Days 6-11) ]
    Two independent readers determined volume of the same tophus by MRI at 2 separate visits scheduled no more than 10 days apart. Difference in volume between Visit 1 and 2 for the same tophus was pooled across readers.

  • Measurement of Tophi by MRI - Difference in Volume Between Readers [ Time Frame: Visit 1 (Day 1) and Visit 2 (Days 6-11) ]
    Two independent readers determined volume of the same tophus by MRI at 2 separate visits scheduled no more than 10 days apart. Difference in Reader 2 volume and Reader 1 volume for the same tophus were pooled across visits.


Biospecimen Retention:   None Retained

Primary Completion Date: January 2003 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
1
Volumes/measurements of tophi determined by serial MRIs
Procedure: MRI
Subjects underwent MRI to evaluate tophi.

Detailed Description:
This is a multi-center, validation study of MRI in the quantitative assessment of gouty tophi. Subjects with palpable gouty tophi (confirmed by aspiration of the tophus) in select anatomical sites (foot, hand or elbow) will undergo pre- and post contrast MRI on two occasions separated by 5 to 10 days. This study will consist of up to 4 study visits.
