| [ Summary ] | Submucosal tumors (SMTs) of the gastrointestinal tract are defined as intramural proliferation underneath the mucosa, and the majority of SMTs are mesenchymal tumors. Mesenchymal tumors are mainly divided into myogenic, neurogenic, and gastrointestinal stromal tumors (GISTs); GIST is the most common mesenchymal tumor of the gastrointestinal tract. Diagnostic imaging modalities (e. g., CT, MRI, and FDG-PET (/CT)) have proven to be useful for malignant tumors staging and recurrence site determination. FDG-PET (/CT) also has been demonstrated to have high diagnostic accuracy in the prediction of malignant potential of neoplasms. Among gastrointestinal mesenchymal tumors, we focused on GIST, leiomyoma, and schwannoma. Furthermore, we evaluated their incidences, biological characteristics, and diagnostic imaging findings. | |
