Comparison of Comfort between Cone Beam Breast Computed Tomography and Digital Mammography

Publication date: Available online 16 September 2019Source: European Journal of RadiologyAuthor(s): Haijie Li, Lu Yin, Ni He, Peng Han, Yueqiang Zhu, Yue Ma, Aidi Liu, Hong Lu, Zhipeng Gao, Peifang Liu, Yaopan Wu, Zhaoxiang YeAbstractPurposeTo compare the comfort levels of cone beam breast computed tomography (CBBCT) and digital mammography.Materials and MethodsOn 409 patients, CBBCT was performed within 1 week after conventional mammography. Patients evaluated their comfort by using an 11-point numerical rating scale (NRS-11) after completing the two examinations. The lower the score was, the more comfortable the examination modality was. The data was divided into different groups according to CBBCT scan mode (non-contrast mode, contrast-enhanced mode), age (≤44, 45∼59 and ≥60), body mass index (BMI) (

By LUKE OAKDEN-RAYNER In surprising news this week, CMS (the Centres for Medicare &Medicaid Services) in the USA approved the first reimbursement for AI augmented medical care. Viz.ai have a deep learning model which identifies signs of stroke on brain CT and automatically contacts the neurointerventionalist, bypassing the first read normally performed by a general radiologist. From their press material: Viz.ai demonstrated to CMS a significant reduction in time to treatment and improved clinical outcomes in patients suffering a stroke.

A 32-year-old woman was treated for breast carcinoma. Posttreatment FDG PET/CT scan revealed complete response, but in the contralateral breast, unexpected incidental intense FDG uptake was seen with a differential diagnosis of both malignant and benign causes. Medical history revealed recent breast contusion. The lesion was further evaluated by mammogram and ultrasound, which were compatible with deep breast bruise. Histopathology showed no malignancy. Subsequent FDG PET/CT study showed breast uptake normalization. This case shows that postcontusion breast hematoma can cause a potential pitfall mimicking breast malignancy on FDG PET/CT.

Medical imaging saves millions of lives each year, helping doctors detect and diagnose a wide range of diseases, from cancer and appendicitis to stroke and heart disease. Because non-invasive early disease detection saves so many lives, scientific investment continues to increase. Artifical intelligence (AI) has the potential to revolutionize the medical imaging industry by sifting through mountains of scans quickly and offering providers and patients with life-changing insights into a variety of diseases, injuries, and conditions that may be hard to detect without the supplemental technology. Images are the largest source...

Conclusions: This pilot study indicated that the uptake of HER2 antagonist 99mTc-HPArk2 correlate with HER2 expression in breast cancer. 99mTc-HPArk2 SPECT/CT can provide specific, non-invasive evaluation of HER2 expression in breast cancer.

Like everyone, I assume I’ll live forever. Although I often wonder whether anyone would come to my funeral and who would wear black, it never actually occurrs to me that there is an endpoint. It’s almost as if I would come along too to watch proceedings running smoothly and along the lines I wanted. Death was something I thought about, but in a rather abstract, offhand sort of way. It happened, of course I knew I would die at some point, but that point was somewhere out there … way off from here, where I am now. And then I hit a brick wall. The wall consisted of a tiny little bit of blood coughed up in s...

Jacinta E. Browne The aim of this work was to develop multimodal anthropomorphic breast phantoms suitable for evaluating the imaging performance of a recently-introduced Microwave Imaging (MWI) technique in comparison to the established diagnostic imaging modalities of Magnetic Resonance Imaging (MRI), Ultrasound (US), mammography and Computed Tomography (CT). MWI is an emerging technique with significant potential to supplement established imaging techniques to improve diagnostic confidence for breast cancer detection. To date, numerical simulations have been used to assess the different MWI scanning and image recon...

While there has been controversy over when and how often women should be screened for breast cancer using mammograms, studies consistently show that screening can lead to earlier detection of the disease, when it’s more treatable. So improving how effectively mammograms can detect abnormal growths that could be cancerous is a priority in the field. AI could play a role in accomplishing that—computer-based machine learning might help doctors to read mammograms more accurately. In a study published Jan. 1 in Nature, researchers from Google Health, and from universities in the U.S. and U.K., report on an AI model ...

CONCLUSION: Imaging tools used to evaluate breast cancer can help determine whether distant metastasis has occurred and in rare cases can help discover other primary cancers. The patient in this case study was 1 of the few patients with an incidental finding of a second nonmetastatic primary malignancy in the lung detected using PET-CT. The risks associated with advanced imaging include exposing patients to additional tests and potentially invasive procedures based on the results. However, in some instances, imaging results can alter the treatment plan and increase survival rates. Further empirical research and case studie...
