Abstract:
The radiological diagnosis and differential diagnosis of intra-axial tumours no longer relies on CT scan and routine MR sequences alone. Standard multiplanar imaging has to be combined with fMRI to allow the exact anatomic location of the lesion and precise determination of the extension of the tumour. Perfusion and diffusion MR is becoming more and more important in the differential diagnosis of cerebral mass lesions and in the grading and typing of gliomas. More sophisticated techniques such as diffusion tensor imaging and spectroscopy will further enhance the value of the radiological studies.
Insights
Advanced MRI techniques like fMRI, perfusion, and diffusion imaging are crucial for accurately diagnosing and characterizing intra-axial brain tumors. These methods improve lesion localization, extent determination, and glioma grading beyond traditional imaging.
Area of Science:
- Neuroradiology
- Neuro-oncology
- Medical Imaging
Background:
- Traditional CT and routine MRI sequences are insufficient for comprehensive intra-axial tumor diagnosis.
