“…This is consistent with other results reviewed in Chapter 1 (section 'Tests of the impact of systems on radiologists' decision-making', p. 5), such as those of Brem and Schoonjans, 32 but runs against the general tenor of findings in evaluations of prompting systems. Studies such as those by Funovics and colleagues 29 or Thurjfell and colleagues 28 have found in favour of the ImageChecker.…”

“…31 The largest reported study of sensitivity using the R2 ImageChecker is that of Brem and Schoonjans, who used a sample of 106 cases including 42 malignant microcalcifications, 40 with benign microcalcifications and 24 normals. 32 Five radiologists participated. Forty-one out of 42 (98%) malignant microcalcifications and 32 out of 40 (80%) benign microcalcifications were prompted at a prompt rate of 1.2 markers per image.…”

Health Technology Assessment is indexed and abstracted in NHS R&D HTA ProgrammeT he research findings from the NHS R&D Health Technology Assessment (HTA) Programme directly influence key decision-making bodies such as the National Institute for Clinical Excellence (NICE) and the National Screening Committee (NSC) who rely on HTA outputs to help raise standards of care. HTA findings also help to improve the quality of the service in the NHS indirectly in that they form a key component of the 'National Knowledge Service' that is being developed to improve the evidence of clinical practice throughout the NHS.The HTA Programme was set up in 1993. Its role is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care.The HTA programme commissions research only on topics where it has identified key gaps in the evidence needed by the NHS.

“…This result is actually consistent with most experimental measurements of the impact of R2 ImageChecker and other similar CAD tools on mammogram reading (e.g. [12][13][14][15][16]). To improve the effectiveness of computer aids, it is desirable to explain why CAD apparently had no effect in these studies.…”

Permanent repository link SHORTENED VERSION OF THE TITLE:Multidisciplinary study of CAD use in mammography FUNDING:The work described in this paper has been partly funded by the UK Engineering and Physical Sciences Research Council (EPSRC) through DIRC, the Dependability Interdisciplinary Research Collaboration, a project investigating the dependability of computer based systems. KEYWORDS:Breast cancer screening, digital imaging, mammography 2 ABSTRACTWe summarise a set of analyses and studies we have conducted to assess the effects of the use of a Computer Aided Detection (CAD) tool in breast screening. We have used an interdisciplinary approach which combines: a) statistical analyses inspired by reliability modelling in engineering, b) experimental studies of mammography experts' decisions using the tool, interpreted in the light of human factors psychology;and c) ethnographic observations of the use of the tool both in trial conditions and in everyday screening practice. Our investigations have shown patterns of human behaviour and effects of computer-based advice that would not have been revealed by a standard clinical trial approach. For example, we found that the negligible measured effect of CAD could be explained by a range of effects on experts' decisions, beneficial in some cases and detrimental in others. There is some evidence of the latter effects being due to the experts using the computer tool differently from the developers' intentions. We integrate insights from the different pieces of evidence and highlight their implications for the design, evaluation and deployment of this sort of computer tool.3

“…This tendency of the effect of CAD on the radiologists was verified in an extended British study design that documented additionally that film readers used CAD not as a detection aid, but rather to exclude any malignant structures [i.e., as a confirmation that a case was benign [17]]. A number of other studies report an unchanged sensitivity [17,42,43] of the radiologists when using CAD prompts. It can be critically summarized that the outcome of these studies depends on the selection criteria of the cases (optimization or preselection of the cases for which CAD should be performed):…”

CAD for mammography: the technique, results, current role and further developments

CAD systems, developed to assist the radiologist in the detection of suspicious lesions on mammograms, are currently controversially discussed. The highly sensitive detection of malignant structures including priors by CAD is linked with a low specific performance and a high rate of falsely positive markings. This causes controversial results regarding the effect of CAD systems for the diagnosing radiologist. This review aims to give an overview of the current literature, to state the currently discussed controversial results of CAD and to give an outlook on the next developments, which are not limited to senology, but include many other applications of CAD systems in radiology.
