New Technology Could Improve Breast Cancer Detection

17.09.2003


Teams of radiologists, scientists and radiographers from The University of Aberdeen, The University of Manchester and The South Manchester University Hospitals Trust will be using the R2 Technology ImageChecker to help detect potentially cancerous areas on mammograms.



The ImageChecker helps radiologists & radiographers in a similar manner to a PC spellchecker by automatically detecting and prompting suspicious areas on mammograms. It acts as a second pair of eyes and therefore could help to make mammogram checks more accurate.

It is hoped that the technology could reduce oversights and bring about earlier detection of cancerous lesions – both of which would reduce patient suffering and treatment costs.


The technology could also potentially alleviate the shortage of radiologists and radiographers which currently exists in the UK. At the moment, many mammograms are checked by two radiologists/radiographers, but the study will look at whether a single radiologist/radiographer prompted by the ImageChecker can produce the same or better results. If this is the case, savings would result.

The joint study is being led by Professor Fiona Gilbert, Head of Radiology at The University of Aberdeen, Dr Sue Astley, Senior Lecturer in Imaging Science at The University of Manchester, Professor Stephen Duffy, Professor of Cancer Screening, Queen Mary College, London and Dr Caroline Boggis, Consultant Radiologist at South Manchester University Hospitals Trust. The study is being funded by Cancer Research UK and the NHS Breast Screening Programme (NHSBSP).

Commenting on the study Professor Gilbert said: “Recent enhancements to the NHS Breast Screening Programme, including the requirement for additional mammogram views (Note 1) and an extended age range of women invited to screening (Note 2) , coupled with a natural increase (Note 3) in the eligible screening population mean that screening volumes are set to increase dramatically.

“There is already a shortage of radiologists and radiographers and in the face of this burgeoning demand, we anticipate problems in delivering the service. This prompting technology needs to be examined in the NHSBSP setting, as it could potentially provide a solution to the shortage of film readers. The research team is confident of the importance and timeliness of this study.”

Dr. Astley from The University of Manchester added: “We will investigate whether individual radiologists, prompted by the ImageChecker, can match the level of detection currently considered to be the gold standard in the UK.

“Known as double reading with arbitration, this gold standard involves independent reading of each mammogram by two radiologists or radiographers with referral to a third radiologist if interpretation differs. We believe that the probability–coded prompt markers provided by the system could permit film readers to utilise the prompting information more effectively. We look forward to the results.”

Dr. Caroline Boggis commented: “This study will evaluate the contribution of R2 / CAD to avoiding potential oversights. If effectiveness is established, the implication will be that the use of CAD will improve confidence in breast screening decisions."

The ImageChecker system digitises and analyses mammograms, displaying its findings on a screen adjacent to the mammogram viewer. Suspicious masses and micro calcifications are indicated by different symbols, sized according to the degree of concern.

The film reader first makes an unprompted assessment of the original mammogram, then consults the CAD prompt image and if appropriate, revises the assessment and decision to recall the patient or not, in light of the additional information.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
