Abstract:
Objective To evaluate MR imaging diagnosis in acute suppurative osteomyelitis at early stage. Methods The axis, sagittal and coronal planes were performed with Philips 0.5 T superconduct MR scanner on 12 cases of acute suppurative osteomyelitis in lower extremity proved by clinical data 2 to 14 days after onset. Results Abnormal signals in marrow were displayed in all 11 cases 3 to 14 days after onset. No abnormality was found in 1 case 2 days after onset. The interface between normal and abnormal marrow became clear as time going on. The lesion presented as patchy low intensity on T 1WI and high signal on T 2WI. The signal changes were marked especially on STIR. Conclusion MRI was superior to other imaging methods in diagnosis of acute suppurative osteomyelitis.
