FES-PET shows promise staging patients with low-grade breast cancer

AuntMinnie

Thus, the researchers aimed to determine prospectively whether 18F-FES PET improves staging for patients with clinical stage II/III or local-regional recurrent, grade 1 or 2, ER-positive breast cancer compared with standard F-18 FDG-PET. The full study is available here.

AI's impact on false-positive mammograms, breast cancer screening performance

AuntMinnie

million mammograms were performed in the U.S. Although mammogram is the most widely used screening modality, a known problem is that 9.5% As is common in Europe, NHS currently uses a two-radiologist reader assessment of breast mammograms, three when there is disagreement. Just over 40.5

AI modeling detects, classifies breast microcalcifications

AuntMinnie

In breast imaging, AI has shown its potential as a clinical assistant to interpreting radiologists. To do so, three radiologists annotated a dataset of mammograms using histology-based ground truth. These networks were also validated and tested using an annotated dataset of 1,000 patients and 1,986 mammograms.

What has radiology learned in 5 years since COVID hit U.S.?

While screening mammography services were halted, Patel and colleagues continued with diagnostic imaging services, especially for symptomatic patients. Her team employed a tracking mechanism for patients who were due for their mammograms once screening operations resumed. So, you really had to crystallize your thoughts around that.

In her presentation, Helen Ngo from University Hospital Freiburg in Germany talked about her teams research, which showed that this trend especially goes for mammograms of less dense breasts. AI is a reliable tool and shows promising diagnostic potential beyond screening, Ngo said.

New AI training strategies stiffen defense against adversarial attacks

AuntMinnie

Methods for training artificial intelligence (AI) diagnostic algorithms can help prevent these models from producing medical errors caused by adversarial attacks, according to research presented at RSNA 2023 in Chicago. Adversarial data produced by projected gradient descent were used to insert noises into mammogram images.

CEM is faster and less costly than MRI and can often be used as a follow-up to an abnormal screening mammogram when it is clinically appropriate. The diagnostic exam typically does not require any additional prior authorization following an abnormal screening exam, whereas using MRI for the follow-up would often require authorization.
