ABSTRACT
AIM:
To differentiate between growing and non-growing intracranial meningiomas using magnetisation transfer ratio (MTR) values with amide proton transfer (APT) and chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI). MATERIALS ANDMETHODS:
Seventeen patients with suspected intracranial meningiomas who underwent APT-CEST MRI from November 2020 to April 2021 were evaluated retrospectively. MTR values on APT-CEST imaging as well as conventional MRI features were evaluated. These parameters were compared in growing meningiomas versus non-growing meningiomas and the findings compared with previous MRI examinations. ROC curve analysis was also performed to determine the diagnostic cut-offs for MTR.RESULTS:
The cohort comprised 10 patients with growing meningiomas (two men [20%], eight women [80%]; mean age [standard deviation (SD)] 59.9 years [16]) and seven patients with non-growing meningiomas (seven women [100%]; mean age [SD] 63.9 years [18.6]). Significant differences were found in MTR values (0.0198 ± 0.0003 versus 0.0131 ± 0.0002; p<0.0001) between the growing meningiomas and non-growing meningiomas groups, respectively. The receiver operating characteristic (ROC) curve analysis showed that MTR values clearly differentiated between growing and non-growing meningiomas. At an area under the ROC curve (AUC) threshold of 0.0151, diagnostic sensitivity, specificity, positive predictive value, and negative predictive values for MTR were 100%, 85.7%, 90.9%, and 100%, respectively.CONCLUSION:
Patients with growing meningiomas could be discriminated from patients with non-growing meningiomas, using the MTR values on post-growth tumour APT-CEST imaging.
