Jeraj, R., Xing, L, “An introduction to molecular imaging in radiation oncology: A report by the AAPM Working Group on Molecular Imaging in Radiation Oncology (WGMIR)”, Med. Phys., 40, 101501 (2013); doi: 10.1118/1.4819818 |

Choice B: | Ultrasound (US) or Magnetic Resonance (MR) Images without contrast |
Choice C: | Positron Emission Tomography (PET), Single Photon Emission Computed tomography (SPECT), Fluorescence, US and/or MR Images using a targeted tracer |
Choice D: | Fluorescence, US and/or MR Images of a physiological tracer |
Question 2: Which parameter of an image guided procedure is most critical for the realization of radical resections? |
Reference: | Meershoek P, Buckle T, van Oosterom MN, KleinJan GH, van der Poel HG, van Leeuwen F (2019) Can fluorescence-guided surgery help identify all lesions in unknown locations or is the integrated use of a roadmap created by preoperative imaging mandatory? A blinded study in prostate cancer patients. J Nucl Med; doi: 10.2967/jnumed.119.235234 |
Choice A: | Ability to plan the procedure based on preoperative 3D imaging roadmaps that display targets within their anatomical context (imaging modalities used suffer from limited signal attenuation by tissue, e.g. SPECT, PET, CT or MR ) |
Choice B: | Ability to provide real-time visual target delineation in the surgical wound (imaging signals used e.g. fluorescence or ultrasound suffer from signal attenuation by tissue) |
Choice C: | Ability to use “GPS-like” navigation (in combination with virtual and/or augmented reality displays) to guide the surgical instruments in the human body |
Choice D: | Back table confirmation (in the OR) of tracer presence in resected tissue |
Question 3: Within the field of surgical guidance there always is a debate on the role of sensitivity (as much signal as possible) vs. specificity (only signal in the relevant tissues). Acknowledging there should always be an interplay between sensitivity and specificity, which of the below properties is most important to pursue when trying to develop a technique for minimally invasive surgery? |
Reference: | Frangioni JV (2009) The problem is background, not signal. Mol Imaging, 8[6], 303-304; PMID 20003888 |
Choice A: | A high sensitivity - enables resection of more lesions reduces the chance of false negatives, but increases the chance of false positives. |
Choice B: | A low sensitivity - enables resection of less lesions, reduces the chance of false positives, but increases the chance of false negatives. |
Choice C: | A high specificity - improves signal to background ratio’s and reduces the chance of false negatives and positives. |
Choice D: | A low specificity - reduces the signal to background ratios and increases the chance of false negatives and positives. |
