Interstitial brachytherapy needles in High Dose Rate radiotherapy patients can be visualised clearly and accurately within clinical tolerance values using just a proton-density StarVIBE sequence instead of registered CT and MR images. This could lead to a reduced radiation dose MR-only workflow without compromising the quality of treatment and a reduction of errors in image registration.
