Occasionally, once activity/weightbearing is increased, an unexpected incomplete response to conservative therapy becomes evident with the return of pretreatment symptoms. In this situation, it is recommended that follow-up imaging be performed as well as re-evaluation of the original imaging studies to determine whether the true etiology of pain was obscured or simply misdiagnosed. CT Area of Interest With IV Contrast There is no relevant literature to support the use of CT area of interest with IV contrast because it does not provide added information over noncontrast imaging with regard to stress injury. CT Area of Interest Without and With IV Contrast There is no relevant literature to support the use of CT area of interest without and with IV contrast because it does not provide added information over noncontrast imaging with regard to stress injury. CT Area of Interest Without IV Contrast CT is useful in identifying possible etiologies in delayed healing after conservative therapy for suspected stress fracture, such as osteoid osteoma or suspected completion of fracture. Stress (Fatigue-Insufficiency) Fracture MRI Area of Interest Without and With IV Contrast MRI with IV contrast may be useful in identifying complications of stress fracture such as osteonecrosis or in suspected osteoid osteoma or tumor causing persistent symptoms or delayed healing after conservative therapy for suspected stress fracture. MRI Area of Interest Without IV Contrast MRI is useful in identifying complications of stress fracture such as osteonecrosis or in suspected osteoid osteoma or tumor causing persistent symptoms or delayed healing after conservative therapy for suspected stress fracture. In athletes, MRI can be used to predict time to return to play on initial diagnosis.
