Bone scan findings were correlated with the final diagnosis in 34 sites of septic arthritis and in 62 sites of osteomyelitis. Bone scan accuracy was 81%. Positive predictive value was 82% for those sites with increased activity and 100% for those sites with decreased activity. Negative predictive value was 63%. Bone Scan Whole Body and 3-Phase Bone Scan Area of Interest There is no relevant recent regarding the use of whole-body bone scan and 3-phase bone scan of area of interest as the next imaging study in the evaluation of suspected septic arthritis. CT Area of Interest There is no relevant literature regarding the use of CT as the next imaging study in the evaluation of suspected septic arthritis. Image-Guided Aspiration Area of Interest Early diagnosis of septic arthritis is extremely important in preventing complications, and US-guided hip aspiration is considered highly accurate [43,61]. In one study, 100% of children were confirmed to have septic hip arthritis via bedside joint aspiration and were able to avoid arthrotomy. However, it should be noted that US guidance for Osteomyelitis or Septic Arthritis-Child aspiration was only provided in one case, and the remainder performed using anatomic landmarks without imaging guidance [62]. In the setting of confirmed transient synovitis, children who underwent US-guided joint aspiration experienced shorter duration of stay and shorter duration of limp compared with those who did not undergo joint aspiration [61]. In patients with suspected or confirmed septic arthritis, femoral neck aspiration performed at the time of incision and drainage was noted to improve diagnosis of concurrent osteomyelitis compared with preoperative MRI alone [63].
