Elastography - Research Background

Researchers at several institutions in Texas, Ohio, and elsewhere have developed elastography techniques for breast cancer and other purposes since the early 1990s.

On Nov. 27, 2006, Dr. Richard Barr of the Northeastern Universities of Ohio College of Medicine presented the results of a study comparing elastograms and biopsies at a meeting of the Radiological Society of North. In the study, 80 patients underwent both elastography-enhanced ultrasound exams and biopsies. Elastograms predicted that 18 of the lesions found would be malignant and 105 would be benign. Biopsies showed that the new imaging technique was off by only one: 17 malignant and 106 benign. At least in this small experiment, elastography gave no false negatives (it didn't miss any tumors that were cancerous) and hardly any false positives (it rarely identified a benign growth as cancerous).

While many more studies must take place, and attitudes must change, before elastography becomes as common as mammography or biopsies as a diagnostic tool, these initial results are encouraging.
