Zusammenfassung
Ziele: To evaluate image fusion of high resolution T2-weighted (T2-w) and parametrically analyzed dynamic contrast enhanced T1-weighted (T1-w) MR images (T1-w DCE MRI) with the planning CT scan within treatment planning systems for radiation therapy of the prostate. Methode: MRI of the prostate was performed on a 1.5 T unit with a phased-array body coil prior to treatment in patients with histologically proven prostate cancer. T2-weighted fast spin-echo images (TR 3220ms, TE 114ms, flip angle 180 deg, FOV 140mm, matrix size 256×256, slice thickness 3mm) and dynamic Gd-DTPA enhanced 3D-FLASH images were acquired…
