EP164 Audit of fiducial marker placement and utility in image guided prostate radiotherapyStereotactic body radiotherapy (SBRT) can deliver high radiation doses to small volumes with very tight margins, which has significant advantages when treating tumours close to the spinal cord or at sites of ...
Purpose: To understand fiducial marker movement in prostate and to improve prostate patient positioning with fiducial markers. Methods: Patient planning CT and positioning CBCT were retrospectively analyzed.CBCTimages were automatically registered to the corresponding CT ones based on their bony structures ...
while this study relied on whole-mount sections for three-dimensional matching between clinical HP-13C-MRI and tissue-based digital pathology, IHC, and spatial transcriptomics, future work in non-surgical patient populations should consider alternative approaches (e.g. fiducial marker placement) to en...
On April 10, 2020, the protocol was amended to allow for 4 months of treatment with androgen deprivation therapy (ADT) that was initiated 1 to 2 months before fiducial marker placement. All patients provided written informed consent for IDE and the PMS before randomization. Randomization and ...

registration-error (TRE) between each MRI and the planning-CT image was calculated. Fiducial marker visibility was rated by two medical physicists with over three years of experience examining MRI-only prostate simulation images. The rater's classification accuracy was quantified using the F 1 score...

As for image-guided radiotherapy, it has been commonly performed through the acquisition of onboard cone beam computed tomography (CBCT) [48]. Nonetheless, CBCT has poor soft tissue discrimination capacity, and therefore invasive placement of radiopaque fiducials to serve as markers of prostate posit...
MRI-based planning, radiopaque hydrogel spacer insertion, and fiducial marker placement are required, and SABR will be delivered on either a standard CT-guided linear accelerator or MR-LINAC. The primary endpoint will be freedom from disease progression, with additional secondary clinical, toxicity, ...
