Usefulness of ultrafast dynamic 3D-T1w data acquisition in detection of hypervascular lesions of the middle ear: first experience.

ABSTRACT

OBJECTIVE: To evaluate ultrafast dynamic 3D-T1w acquisition for improved detection of tympanic hypervascularized lesions. METHODS: Retrospective evaluation of a total of 50 patients referred from ENT-Department for suspected tympanic lesion. All underwent magnetic resonance imaging including ultrafast dynamic 3D-T1w acquisition imaging. Quantitative and qualitative evaluation was performed as well as statistical analysis. Comparison with intra-operative results. RESULTS: 12/50 patients showed a hypervascularized lesion proved intraoperative as 8 paragangliomas, 2 adenoms, 1 hemangioma and 1 neurinoma. 8/50 do not show hypervascularization though an enhancement was detected. Intra-operative granulation tissue was found. 30 patients did not show any lesions or enhancement. Sensitivity and specificity was 100%/100% for ultrafast dynamic imaging. CONCLUSION: Additional ultrafast dynamic 3D-T1w imaging is superior to conventional imaging in detection of hypervascularized lesions.
