Résumé
BACKGROUND AND PURPOSE: The aim of this study was to test a new ultrasound software tool to assess pathological perfusion in a brain tumor patient.
METHODS: Tissue harmonic imaging (THI) enables an improved depiction of brain morphology, employing nonlinear parenchyma and ultrasound contrast agent (UCA) backscatter information. With specialized software, morphological information can be separated from perfusion information. Both can be superimposed at a preferred mixing ratio in a single image.
RESULTS: Using THI and a perfluoropropane-based UCA, a pathologic perfusion pattern described by abnormal perfused areas in the tumor region could be demonstrated. After superimposing morphologic and perfusion information, subtle structural tumor inhomogeneities were depicted. Craniopharyngioma structure and perfusion defect were confirmed by T2-weighted and perfusion-weighted magnetic resonance imaging.
CONCLUSION: Transcranial duplex sonography in combination with contrast specific imaging methods might be helpful to visualize perfusion defects without loss of morphological information.
