The dual-plane co-RASOR sequence is able to differentiate between a LDR brachytherapy seeds and gold fiducial markes used in prostatic imaging, by exploiting signal pileups and rewinding them radially inwards using different off-resonant frequency offsets and has the potential to avoid a radiological CT scan that’s clinically used to differentiate the two in boost therapy.
