Abstract
A new high-speed, high-resolution digitiser has provided a facility with which new means of communication and interaction become possible. 1. The DicomNow Digitiser camera system will scan mammography film at a 16-bit depth in less than 1 second. 2. The thresholds for compression of mammogram images have previously been confirmed at a ratio between 65:1 and 80:1. 3. New opportunities for transmission between centres; difficult analogue films can be digitised quickly, then compressed and sent for consensus/arbitration views from an expert panel or submitted to computer-aided diagnosis. 4. Applications to multidisciplinary team meetings in which all types of images, patient information and pathology are shared via any Internet link in a virtual meeting room. 5. The speed of DicomNow and the compression system removes time limitations for telemedicine communication speeds in mammography. 6. Archive potential to reduce storage cost and support disaster-recovery initiatives. 7. Modular training programmes will benefit students with access to high-resolution images via the scanning and compression technology. 8. Higher level studies of subtle features of image interpretation for validated case studies. Each of these elements will be expanded to illustrate the effects of high-speed digitising on breast cancer management.
Highlights
Breast-sparing oncoplastic procedures (BSOP) offer a predictive marker guiding use of anti-oestrogen therapy, and radical new alternative to mastectomy and conventional breast- expression profiling appears to select patients more or less likely to conserving surgery in early breast cancer treatment
The aim was to document attitudes to male radiographers and the effect on the programme performance parameters through a postal questionnaire completed by 85.8% of a random sample of 2,000 women recently screened by BreastCheck
Nine per cent would not have proceeded if the radiographer was male; 17.5% agreed that ‘If there were male radiographers I would not return for another screening appointment’; and 18.3% were unsure
Summary
Breast-sparing oncoplastic procedures (BSOP) offer a predictive marker guiding use of anti-oestrogen therapy, and radical new alternative to mastectomy and conventional breast- expression profiling appears to select patients more or less likely to conserving surgery in early breast cancer treatment. We have compared the results of screening with analogue and digital technology over our first 2 years, in terms of recall rates, cancer detection rates and positive predictive value, and found no overall significant difference in any of these parameters. Abnormalities are graded as A, B or C at consensus by the radiologists and reporting radiographers depending upon the mammographic likelihood of cancer and biopsy This means that patients can be allocated to one of our three assessment clinics and at specific times within those clinics to facilitate workflow. Methods A retrospective analysis of all breast cancer patients with recurrence who had completed 5 years of follow-up was performed. Infection control is not routinely included in the quality assurance process of all units
