Researchers in the U.K. are preparing to launch a 1.6 million pound ($2.6 million U.S.) trial to determine the efficacy of digital breast tomosynthesis (DBT) to screen for breast cancer.
Approximately 7,000 women in Aberdeen, Glasgow, Manchester, London, and Guildford will be invited to participate in the three-year study.
Professor Fiona Gilbert, head of imaging at the University of Aberdeen, is the chief investigator of the study, which is funded by a grant from the National Institute for Health Research (NIHR) Health Technology Assessment program.
Women who are recalled after an abnormal screening mammogram will be invited to participate in the trial, which will begin recruiting volunteers early next year. Trial participants will receive a standard mammogram and a DBT examination. The 2D and 3D images will be collected and reviewed independently by radiologists at another facility.
The research team will then compare the number of cancer cases detected by each imaging technique, the number of false positives, and the relative effectiveness of DBT in women with dense-tissue breasts, which can be a cancer risk.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
