Comparison of MRI pulse sequences in defining prostate volume after permanent implantation

To determine the relative value of three MRI pulse sequences in defining the prostate volume after permanent implantation.A total of 45 patients who received a permanent 125I implant were studied. Two weeks after implantation, an axial CT scan (2 mm thickness) and T1-weighted, T1-weighted fat saturation, and T2-weighted axial MRI (3-mm) studies were obtained. The prostate volumes were compared with the initial ultrasound planning volumes, and...
