摘要: Tumor-to-brain contrast after gadolinium administration using MP-RAGE and T1-SE scans in patients with primary secondary brain tumors was significantly higher at 3 T than 1.5 T. The subjective assessment of cumulative triple-dose Tesla images obtained the best results detection metastases compared other sequences followed by enhanced images. In macroadenomas hypophysis, contrast-enhanced MRI superior to standard diagnosis cavernous sinus infiltration visualization cranial nerves within sinus. Due spatial resolution, MR venography showed more details around T, additionally stronger susceptibility weighting signal-to-noise ratio summary, gadolinium-based agent produces between tumor normal helps detect cerebral versus single triple dose, improves evaluation makes clinically attractive increase resolution same measurement time, thus providing detailed information.
