Session Title: The Developing Role of Medical Physics and Imaging in Digital Pathology
Question 1: After prostate brachytherapy, the most common site of recurrence is:
Reference:Arrayeh E, Westphalen A, Kurhanewicz J. Does local recurrence of prostate cancer after radiation therapy occur at the site of primary tumor? Results of a longitudinal MRI and MRSI study. Int J Radiat Oncol Biol Phys 2012.
Choice A:At the site of extraprostatic extension.
Choice B:Within the regional lymph nodes.
Choice C:Near the site of the dominant intraprostatic lesion.
Choice D:All of the above
Question 2: In fiducial point-based registration, the target registration error is calculated based on the postregistration position of the fiducial points used to determine the transformation.
Reference:J. M. Fitzpatrick and J. B. West, "The distribution of target registration error in rigid-body point-based registration," in IEEE Transactions on Medical Imaging, vol. 20, no. 9, pp. 917-927, Sept. 2001, doi: 10.1109/42.952729.
Choice A:True
Choice B:False
Question 3: The addition of radiomic measures used in conjunction with pathology compared with pathology alone could potentially allow better characterization of the spatial heterogeneity of cancer

Radiomics: from qualitative to quantitative imaging. Br J Radiol. 2020 Apr;93(1108):20190948. doi: 10.1259/bjr.20190948. Epub 2020 Feb 26. PMID: 32101448; PMCID: PMC7362913.
Choice A:True
Choice B:False
Question 4: The addition of radiomic measures used in conjunction with pathology compared with pathology alone could potentially improve the positive predictive value of screening and reduce false positives in screening.

Choice A:True
Choice B:False
