Imaging findings OR Procedure details
Elastography is a very helpful technique that adds value to the sonographic examination by enabling you to evaluate the stiffness of tissue.
Studies have shown that a combination of ultrasound elastography and sonography had the best results in detecting cancer and potentially could reduce unnecessary biopsies.
•“Quantifying manual palpation”
•Elasticity of lesion
–Stiffer a lesion the more likely it is malignant
–Except cysts!
•Quantification
–Graphs vs colour map
–Fat:Lesion ratio•>10 (more likely malignant)
•Application:
–Distinguishing benign from malignant
–Reassurance on B Mode appearance
•Similar to colour Doppler
•Pitfalls
–Cysts
–Fibrous tissue
–Cancers with necrotic soft centres
•Easy to use compared with other manufacturers
•ElastoQ allows quantification and not only provides a colour map
–Accuracy of compression and decompression cycle
–Fat:lesion ratio
•Distinguishing benign from malignant
–Promising data
–“Reassurance”
–Pitfalls
•Tumour extent
–Needs further scientific trials
–Response to treatment
