Outcome Measures

Primary Outcomes (2)

  • Measurement of Tophi by MRI - Difference in Volument Between Visits

    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.

    Visit 1 (Day 1) and Visit 2 (Days 6-11)

  • Measurement of Tophi by MRI - Difference in Volume Between Readers

    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.

    Visit 1 (Day 1) and Visit 2 (Days 6-11)

Study Arms (1)

1

Volumes/measurements of tophi determined by serial MRIs

Procedure: MRI

Interventions
