New Ultrasound Tech Slashes Breast Biopsies
6 Apr
Summary
- Combined ultrasound and DOT imaging improves breast cancer diagnosis accuracy.
- Study showed a 25% reduction in benign breast biopsies.
- New method highlights blood vessel and oxygen levels for cancer detection.
A groundbreaking imaging technique that merges ultrasound with diffuse optical tomography (DOT) is poised to significantly enhance breast cancer diagnosis accuracy, potentially reducing the number of invasive biopsies performed. This combined approach provides structural information via ultrasound and functional insights into blood hemoglobin and oxygen levels through DOT, key indicators of tumor activity.
In a study involving 226 patients, radiologists using the enhanced imaging found distinct differences between cancerous and benign lumps. Cancerous tissues exhibited elevated hemoglobin and reduced oxygen compared to non-cancerous ones. This improved diagnostic capability resulted in an approximate 25% decrease in biopsies for benign lumps, aligning with medical recommendations.
This advancement offers a more precise and efficient alternative to current screening methods. While other imaging techniques like mammography and MRI can also be combined with DOT, ultrasound integration is proving more practical for routine clinical use. Ongoing research aims to further refine the technology, incorporating AI to optimize data processing, ultimately seeking to minimize avoidable procedures and improve patient outcomes while controlling healthcare expenditures.
