Artificial intelligence helps doctors detect breast cancer better

Published

Breast cancer can be detected more accurately using artificial intelligence, according to a new study.

Researchers found that AI improves breast cancer detection accuracy for radiologists when reading screening mammograms, helping them devote more of their attention to suspicious areas.

Previous studies have shown that AI for decision support improves radiologist performance by increasing sensitivity for cancer detection without extending reading time.

However, the positive impact of AI on radiologists’ visual search patterns remained underexplored until now.

Dutch researchers used an eye-tracking system to compare radiologists’ performance and visual search patterns when reading screening mammograms with and without an AI decision support system.

The system included a small camera-based device positioned in front of the screen with two infrared lights and a central camera.

The infrared lights illuminate the radiologist’s eyes, and the reflections were captured by the camera, allowing for the computation of the exact coordinates of the radiologist’s eyes on the screen.

Study joint first author Jessie Gommers, from the Department of Medical Imaging at Radboud University Medical Center, said: “By analyzing this data, we can determine which parts of the mammograms the radiologist focuses on, and for how long, providing valuable insights into their reading patterns.”

Twelve radiologists read mammography examinations from 150 women, 75 with breast cancer and 75 without, for the study, published in the journal Radiology.

Breast cancer detection accuracy among the radiologists was higher with AI support compared with unaided reading.

There was no evidence of a difference in mean sensitivity, specificity or reading time.

Doctoral candidate Gommers said: “The results are encouraging.

“With the availability of the AI information, the radiologists performed significantly better.”

Eye tracking data showed that radiologists spent more time examining regions that contained actual lesions when AI support was available.

Gommers said: “Radiologists seemed to adjust their reading behavior based on the AI’s level of suspicion: when the AI gave a low score, it likely reassured radiologists, helping them move more quickly through clearly normal cases.

“Conversely, high AI scores prompted radiologists to take a second, more careful look, particularly in more challenging or subtle cases.”

She said the AI’s region markings functioned like visual cues, guiding radiologists’ attention to potentially suspicious areas.

She explained that, in essence, the AI acted as an additional set of eyes, providing the radiologists with additional information that enhanced both the accuracy and efficiency of interpretation.

Gommers said: “Overall, AI not only helped radiologists focus on the right cases but also directed their attention to the most relevant regions within those cases, suggesting a meaningful role for AI in improving both performance and efficiency in breast cancer screening.”

She noted that overreliance on erroneous AI suggestions could lead to missed cancers or unnecessary recalls for additional imaging.

However, multiple studies have found that AI can perform as well as radiologists in mammography interpretation, suggesting that the risk of erroneous AI information is relatively low.

To mitigate the risks of errors, Gommers says it is important that the AI is highly accurate and that the radiologists using it feel accountable for their own decisions.

She said: “Educating radiologists on how to critically interpret the AI information is key.”

The researchers are now conducting additional reader studies to explore when AI information should be made available, such as immediately upon opening a case, or on request.

The team is also developing methods to predict if AI is uncertain about its decisions.

Gommers added: “This would enable more selective use of AI support, applying it only when it is likely to provide meaningful benefit.”

Sony WH-1000XM6 review: raising the bar for noise-cancelling headphones | Headphones

Published

on


Sony’s latest top-of-the-range Bluetooth headphones seek to reclaim the throne for the best noise cancellers money can buy with changes inside and out.

The Sony 1000X series has long featured some of the best noise cancelling you can buy and has been locked in a battle with rival Bose for the top spot.

The WH-1000XM6 replace the outgoing XM5 model and cost £399 (€449/$449/A$699) – far from cheap but not the most expensive among peers either.

The outside design looks very similar to their predecessors, with smooth, soft-touch plastic bodies, plush earpads and headband, and a subtle Sony logo on the arms. The earcups now swivel and fold to allow the headphones to be more compact for travel in a redesigned hard fabric case with a magnetic clasp.

The new headphones are light but feel solid and ready for the rigours of travel or a commute. They fit well, with enough pressure to keep them in place without any discomfort, though the Bose QC Ultra are more comfortable. The earcups of the XM6 are slightly shallow compared with the Bose, which made getting a proper fit with glasses a little trickier.

The right earcup has a responsive touch panel to handle playback and volume controls with swipes and taps, which works well unless you’re wearing gloves. The left earcup has a power button, a 3.5mm headphones socket and a button for toggling noise-cancelling modes.

The XM6 can connect with two devices simultaneously through Bluetooth 5.3 and support the SBC, AAC and LDAC audio formats. They also support Bluetooth LE (LC3), the next generation of Bluetooth audio connectivity, which has yet to see widespread adoption but is good for future-proofing. Call quality is very good, sounding natural and full in either quiet or noisy environments, with the option of side tone, where you can hear yourself through the headphones.

Specifications

  • Weight: 254g

  • Drivers: 30mm

  • Connectivity: Bluetooth 5.3 with multipoint, 3.5mm, USB-C charging

  • Bluetooth codecs: SBC, AAC, LDAC, LC3

  • Rated battery life: 30 hours ANC on

The headphones lasted slightly longer than their rated 30 hours in testing, managing more than 32 hours between charges using noise cancelling, which is very competitive and certainly long enough for a couple of weeks of commuting. They charge via USB-C in about 3.5 hours and can be used via Bluetooth or the headphones jack while being charged.

Impressive noise cancelling

Inside the XM6 is the first chip upgrade in quite a few years. The new QN3 processor is seven times as fast as the previous model and supports 12 microphones for detecting unwanted noise, delivering some of the most impressive noise cancelling I’ve experienced in a long time.

Most good noise-cancelling headphones handle the low rumbles of engines and other roar-type sounds well, but even the best struggle with higher pitch tones such as keyboard taps and background chatter. Here is where the XM6 have raised the bar, doing a better job than others of neutralising those annoying higher tones, so much so that train and bus announcements were almost inaudible, particularly when listening to music.

They also have a very good, natural-sounding ambient mode allowing you to clearly hear the outside world. There are 20 different levels to choose from or a system to automatically adjust it depending on the background noise. It can also allow voices through while blocking other sounds.

The Sony Sound Connect app controls modes, adjust settings, has a full EQ and performs updates. It also enables location and activity-based modes. Composite: Samuel Gibbs/The Guardian

The headphones produce the sort of rounded, well-controlled and detailed sound you should expect from a market leader. They deliver power and solid bass when needed, while preserving detail across the range with excellent separation of tones. They can be a little clinical in some tracks that require a more raw sound, such as Nirvana’s Smells Like Teen Spirit. They have a warm and slightly bass-accentuated profile out of the box that is a great listen, but a full equaliser allows you to adjust the sound to taste.

The XM6 also support various sound modes, including a novel background music feature that makes it sound as if you’re in a cafe or living room, plus a cinema audio mode for movies. They can also be used with Sony’s 360 Reality Audio system or Android’s built-in spatial audio system including head tracking with supported phones.

Sustainability

The headphones are generally repairable and were praised for a more repairable design by the specialists iFixit. The earcups can easily be removed. The headphones are made with recycled plastic.

Price

The Sony WH-1000XM6 cost £399 (€449/$449.99/A$699.95). For comparison, the Bose QuietComfort Ultra cost £350, the Sonos Ace cost £449, the Beats Studio Pro cost £349.99, the Sennheiser Momentum 4 Wireless cost £199 and the Fairbuds XL cost £219.

Verdict

Sony has set a new bar for noise cancelling with its sixth-generation 1000X series headphones. The WH-1000XM6 cut out more of the difficult higher-tone noise such as background chatter better than any other rivals.

The rest is a refinement on previous models. Quality sound makes them a delight to listen to. They are light and comfortable to wear with good controls. Solid 32-plus-hour battery life, a folding design and an excellent case make them easy to live with.

Bose still holds the comfort crown with the QC Ultra, Sony’s design is a bit boring and they certainly aren’t cheap at £400, even if some rivals cost a lot more. But if you want the best noise cancelling money can buy, the WH-1000XM6 are it.

Pros: new best-in-class noise cancelling, great sound, spatial audio, light and comfortable, fold up for travel with great case, Bluetooth multipoint, Bluetooth LE/LC3 support, 32-hour battery life, good controls, good cross-platform control app, more repairable design.

Cons: expensive, dull-looking, no water resistance, spatial audio limited with an iPhone.
