TU‐C‐J‐6B‐07: 3DUS, MRI and CT Prostate Volume Definition: 3D Evaluation of Intra‐ and Inter‐Modality and Observer Variability

Abstract: Purpose: To produce a complete three‐dimensional description of the accuracy, variability significance of differences in prostate volume estimation using 3DUS, MR and CT imaging. Method and Materials: Ten patients underwent 3DUS, MR (axial FSE T2‐weighted) and CT imaging 28–33d after I–125 implant (74–112 seeds, mean=93.3). MR prostate volume range was 22.6–50.8cc (mean=31.9cc). Seven experienced observers contoured prostate volumes in 2.5 mm slice increments, twice for each patient, while blind to image dupli… Show more

“…12 Prostate CT volumes have been reported to be larger than prostate MR volumes by up to 40%. 13 Imaging techniques such as projection radiography, portal imaging, and cone beam CT have been employed in image guided radiation therapy ͑IGRT͒ to compare daily images to the reference CT. Only an in-treatment room CT system 14 and U.S. system 15 are capable of true intramodality verification between daily and treatment planning images.…”
