Abstract
Digital mammography is being introduced worldwide in fixed-site screening and diagnostic clinics. BreastScreen Australia services use mobile vans to deliver screening to women in rural and remote Australia. BreastScreen Victoria (BSV) has installed a Computerised Radiology (CR) unit on a mobile van, while BreastScreen Tasmania (BST) has installed a Direct Radiology (DR) system. Digital systems offer benefits over analogue systems on mobile vans. One benefit is image processing without chemicals. Currently, radiographers on BSV and BST mobile vans work 'blind'. They cannot process and view images due to difficulties in maintaining processor quality when vans are moving. Unprocessed films are couriered across the country and women must return if repeat views are required. Digital imaging overcomes this limitation as radiographers can view their images instantaneously. However, digital systems in a mobile environment pose specific problems. Harsh Australian conditions affect system reliability. Movement along rural country roads and temperature fluctuations from -5°C to over 40°C can affect the stability of detectors and lasers. Limited broadband infrastructure poses difficulties in meeting IT and communication network requirements. This poster reports on implementation challenges and compares the strengths and weaknesses of using CR and DR in a digital mobile environment in Australia.
Highlights
Axillary lymph node dissection has been standard practice for staging invasive breast cancer
Best estimates for where to credit this dramatic drop in death rate place approximately 50% of the credit with improved adjuvant chemotherapy and 50% with mammography
Full field digital mammography (FFDM) had a higher detection rate for ductal carcinoma in situ (DCIS) but no difference was observed for invasive tumours
Summary
Axillary lymph node dissection has been standard practice for staging invasive breast cancer. Aim To assess the feasibility of surgeons performing breast US in symptomatic breast clinics either as an adjunct to triple assessment or on their own for diagnostic and therapeutic purposes. The performance of individual units is monitored to ensure all women have access to an excellent service Aim This project aims to demonstrate how the Liverpool Breast Unit addressed failure to meet the national quality standard for the benign. Method A retrospective review of the records of patients who had undergone benign biopsy (2001–2002) was conducted to establish reasons for surgical referral and suggest corrective measures to enable the unit to meet the standard in the future. Columnar cell change (CCC) is diagnosed on core biopsies performed for indeterminate microcalcification. Method Mammograms of 33 cases with established CCC on core biopsy were reviewed and the radiological features, follow-up imaging and surgical excision histology (if performed) were collated. The results were completed when all units were undergoing assimilation onto the new banding procedures
