MRI and Xrays
After the history and physical examination have been completed by your doctor, and there is a high level of suspicion of hamstring injury x-rays of the pelvis may be performed to rule out any breaks in the bone. If a fracture is identified, a CT scan may assist in the assessment of displacement and fracture configuration for a possible surgical procedure. More commonly, no fractures are identified and an MRI is ordered to look at the area of a possible tear.
In some cases a hamstring injury can be evaluated with ultrasound (U/S) in the office. While U/S can be extremely user specific it can also be highly accurate to evaluate partial tears and partial tears. It can help the physician make a decision on how to approach the treatment.
