Is FDG PET/MRI better than 18F-FDG PET/CT in diagnosing osteomyelitis: Study

In a new study published in the European Journal of Hybrid Imaging, suggests that 18F-FDG PET/MRI is an effective alternative to 18F-FDG PET/CT in the diagnosis of osteomyelitis.

In the complex diagnostic work-up of osteomyelitis, modalities including magnetic resonance imaging (MRI) and 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography, coupled with computed tomography (PET/CT), are frequently utilized. Based on the opinions of experts and past qualitative research, PET/MRI is a relatively new hybrid modality with proposed uses in bone infection imaging. Compared to 18F-FDG PET/CT, 18F-FDG PET/MRI offers the benefits of a lower radiation dosage, more soft tissue data, and is thought to be more useful for surgical planning.

A nuclear medicine doctor and a radiologist retrospectively evaluated 36 patients who had 18F-FDG PET/MRI images for possible osteomyelitis. Sensitivity, specificity, and accuracy were assessed using the orthopedic surgeon's clinical evaluation as the gold standard (based on further intraoperative microbiology or long-term follow-up). Receiver operating characteristics (ROC) were used to measure and analyze standard uptake values (SUV).

The key findings of this study were:

1. The sensitivity, specificity, and accuracy of 18F-FDG PET/MRI were 78%, 100%, and 86% in this first research to statistically assess their diagnostic value.

2. The SUV max, target to background ratio, and SUV max ratio each had an area under the ROC curve of .736, .755, and .769, respectively.

3. These findings are comparable to the diagnostic value for 18F-FDG PET/CT imaging of osteomyelitis reported in the literature and are not statistically different.

In conclusion, the authors suggest 18F-FDG PET/MRI as an option to 18F-FDG PET/CT in the diagnosis of osteomyelitis, if accessible, based on the benefits of 18F-FDG PET/MRI indicated above and the diagnostic value presented here.
