Imaging of MRONJ was investigated in a multicenter study. Periosteal reactions were found in 34.1% (265/777). This was considered a possible indicator of treatment. In addition, 3.5% (27/777) of cases were diagnosed as MRONJ even though there was no osteolysis on CT. The appropriate treatment and outcome of each type, as well as imaging modalities other than CT, such as MRI and scintigraphy, will be discussed in the future.

Patients with MRONJ who visited a participating institution between January 1, 2011 and December 31, 2021 and had a CT scan within one month of their initial visit were included.
If the principal investigator or a research associate at the research institution receives a request from a research subject, etc., to refuse to use the information, the principal investigator or research associate will confirm and record the refusal. The principal investigator who confirms the request for refusal of use will take appropriate measures not to provide the information if it has not been provided. If the information has already been provided, the Principal Investigator will be informed of the withdrawal as soon as possible, together with the identification code. Upon receipt of the report, the principal investigator will remove all information regarding the subject's research from the analysis.
