TL;DR: Although the system has less spatial resolution than screen-film technology, the strength of postacquisition image processing to enhance pathology and view obscured anatomy makes CR imaging attractive to technologists and radiologists.

TL;DR: A framework is proposed, using computed tomographic angiography as a model, that should be considered in the optimal design of future imaging research and would potentially provide payers with data to make appropriate reimbursement decisions.
Abstract: Patients, physicians, and payers are facing a significant increase in cardiovascular (CV) imaging use, resulting in skyrocketing societal costs, without clear improvement in patient outcomes. The need for studies evaluating the effects of CV imaging that assess appropriate end points is critical to address continued concerns over the lack of well-designed clinical studies. Thus, the investigators propose a framework, using computed tomographic angiography as a model, that should be considered in the optimal design of future imaging research and would potentially provide payers with data to make appropriate reimbursement decisions. The inclusion of risk stratification, randomization, multiple-site participation, and multigeography site enrollment are key elements in the construction of such studies. Meaningful end points with regard to operating characteristics, downstream testing, CV event rates, outcomes, and costs are essential to appropriately evaluate any new imaging technology. Only once better level evidence is formed to support CV imaging can the central issues of quality and appropriateness of CV imaging truly be evaluated. If the CV community does not embrace this type of scientific evaluation of CV imaging modalities and fails to adequately identify the value in these techniques, it may ultimately lose the ability to use them to provide optimal care to its patients.

TL;DR: In all prostate cancer disease states, exciting novel imaging technology is being tested that may affect the future care of patients, and important issues still need to be resolved, including standardizing patient populations within trials, demonstrating the reproducibility of these techniques between different centers, and understanding how information gained from these techniques should influence patient care.
Abstract: In all prostate cancer disease states, exciting novel imaging technology is being tested that may affect the future care of our patients. New US, MRI, and nuclear medicine techniques are improving both the ability to stage patients and to follow treatment-related changes. See Table 3 for a summary of these novel imaging techniques. Important issues still need to be resolved, including standardizing patient populations within trials, demonstrating the reproducibility of these techniques between different centers, and understanding how information gained from these techniques should influence patient care. We eagerly await answers to these questions.

TL;DR: In this article, a real-time intraoperative HSI (iHSI) system is presented that allows for realtime wide-field HSI and responsive surgical guidance in a highly constrained operating theatre.
Abstract: Despite advances in intraoperative surgical imaging, reliable discrimination of critical tissue during surgery remains challenging. As a result, decisions with potentially life-changing consequences for patients are still based on the surgeon's subjective visual assessment. Hyperspectral imaging (HSI) provides a promising solution for objective intraoperative tissue characterisation, with the advantages of being non-contact, non-ionising and non-invasive. However, while its potential to aid surgical decision-making has been investigated for a range of applications, to date no real-time intraoperative HSI (iHSI) system has been presented that follows critical design considerations to ensure a satisfactory integration into the surgical workflow. By establishing functional and technical requirements of an intraoperative system for surgery, we present an iHSI system design that allows for real-time wide-field HSI and responsive surgical guidance in a highly constrained operating theatre. Two systems exploiting state-of-the-art industrial HSI cameras, respectively using linescan and snapshot imaging technology, were designed and investigated by performing assessments against established design criteria and ex vivo tissue experiments. Finally, we report the use of our real-time iHSI system in a clinical feasibility case study as part of a spinal fusion surgery. Our results demonstrate seamless integration into existing surgical workflows.
