Anyone that has worked with ultrasound imaging knows how difficult it is to recognise structures with the naked eye. Training and experience play a very important role in interpreting those images, and, most importantly, in recognising anomalities.
A recent study by researchers from California has shown that detailed instruction in obtaining 3DUS images of fetal profiles improved the image quality obtained by phisicians. Teaching physicians in a standardized way may help improve the use of 3DUS in clinical practice for a broader spectrum of pathologies: for instance, in image guidance for radiotherapy & brachytherapy in gyneacology, breast, prostate and other cancer types.

Researchers from the Mechanical, Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, Troy, NY USA have developed an algorithm that makes use of the elasticity properties of tissues to characterize malignant tumors. They use an ultrasound device and they process the radiofrequency data to reconstruct the linear and non-linear elasticity properties of tissue, by calculating the displacement within the tissue and mapping the spatial distribution with the material properties that would give that displacement. In order to measure the non-elasticity properties, the tissue needs to be deformed up to 20%, which limits the areas of application of this technology. Currently, they are investigating atherosclerosis disease and skin cancer, besides breast.

The Nov. 30 release by the RSNA that highlights research indicating the potential of elastography to reduce the number of breast biopsies, might be an indication that this technique is ready for clinical routine.

At A Glance
# Elastography can help distinguish cancerous from benign breast lesions.
# Elastography has the potential to reduce unnecessary breast biopsies.
# Currently, 80 percent of breast biopsies yield benign results.
