Initial Imaging Techniques
Plain radiographs are the first step but often miss early stress fractures. Changes like callus formation are visible weeks after symptoms start. For quicker diagnosis, doctors may use ultrasound to detect periosteal edema.
Advanced Imaging Options
If the initial tests are inconclusive, MRI and technetium bone scans can confirm a fracture within days of symptoms. These methods reveal detailed images of bone stress. CT scans are reserved for complex cases needing detailed fracture information.
