After viewing this exhibit, the viewer will understand: a) different RT methods to treat prostatic carcinoma, b) the importance of MR for RT treatment planning and, c) how to optimize treatment planning studies.

1. Review RT methods in prostate cancer including: brachytherapy and image guided (intensity modulated, stereotactic radiosurgery, proton) RT (IGRT) techniques. 2. Review advantages of MR for depiction of regional anatomy discussing anatomic pulse sequences including 2D and 3D Fast Spin Echo. 3. Discuss the role of primary tumor localization with multi-parametric MR to boost areas of dominant tumor potentially improve outcomes. 4. Review types of implanted devices, discussing the advantage of using platinum (rather than gold) fiducials for planning of IGRT. 5. Review available pulse sequences and introduce the novel application of multi-echo gradient recalled echo for improved localization of seeds and fiducial markers facilitating RT planning.
