Abstract
- Summary: Ameloblastomas and keratocystic odontogenic tumors (KCOT) are typical jawbone tumors. In addition, dentigerous cysts (DC) and radicular cysts are the most common cystic jawbone lesions, and simple bone cysts (SBC) are the most common jawbone pseudocysts. When these lesions are unilocular, it can be difficult to diagnose them by radiography. In recent years, adding magnetic resonance (MR) imaging to obtain information about soft tissue has been shown to improve the accuracy of jawbone lesion diagnosis. We also have reported MR imaging features of jawbone lesions. However, no systematic method for MR imaging diagnosis of jawbone lesions has been reported. In this review, we examine unilocular lesions such as ameloblastoma, KCOT, adenomatoid odontogenic tumour (AOT), DC, and SBC. First, we describe the MR imaging features of each lesion. Then, we describe our novel MR imaging diagnostic protocol. Using our MR imaging diagnostic protocol to diagnose 31 cases, we obtained a positivity rate of 71.0%. The use of our MR imaging diagnostic protocol for unilocular lesions, which are especially difficult to differentiate by radiography, would improve the morphological and qualitative diagnosis of soft tissue lesions.
