Best Initial Imaging for Hyperuricemia with Foot Pain

Rationale for Initial Radiography

The American College of Radiology recommends plain radiography of the foot as the best initial imaging study for patients with elevated uric acid and foot pain, as it excludes alternative diagnoses, provides baseline assessment of joint architecture and bone integrity, and is cost-effective with minimal radiation exposure 1, 2
Plain radiography serves to exclude alternative diagnoses that may mimic gout, including fractures, osteoarthritis, stress injuries, tarsal coalitions, and other osseous abnormalities that require different management strategies 1, 3
Weight-bearing views are specifically recommended when feasible, as they optimize visualization of foot structures and joint alignment 3, 4

The American College of Radiology advises against skipping radiographs even with known hyperuricemia, as other pathology must be excluded first 1, 2
The American College of Radiology recommends against ordering ankle radiographs for foot pain, as standard foot views are required for proper visualization of midfoot and forefoot structures 3
The American College of Radiology advises against relying solely on radiographs for stress fractures, which have only 12-56% sensitivity on plain films 1, 3
Proper views, including anteroposterior, lateral, and oblique projections, should be obtained to ensure accurate diagnosis 3, 5
MRI without contrast is appropriate for evaluating occult fractures or stress injuries if radiographs are negative, assessing soft tissue pathology, and detecting bone marrow edema or early erosive changes 1, 2
