Ultr<strong>as</strong>ound el<strong>as</strong>tography is b<strong>as</strong>ed on the principle that malignant tissue is stiffer than nonmalignant<br />
tissue. A conventional ultr<strong>as</strong>ound can be used with some additional software to<br />
form the el<strong>as</strong>togram. This is the first time that ultr<strong>as</strong>ound el<strong>as</strong>tography is introduce to the<br />
EADMFR audience. Ultr<strong>as</strong>ound el<strong>as</strong>tography h<strong>as</strong> been found to be useful in evaluating bre<strong>as</strong>t<br />
lesions and have been used to help to distinguish between malignant and benign lesions<br />
which have reduced the number of biopsies performed in the bre<strong>as</strong>t clinic.<br />
We are applying the same el<strong>as</strong>tography principles in analysing the different lumps and bumps<br />
in the head and neck. A small study h<strong>as</strong> been devised to look at a group of patients who<br />
presented to the dental radiology department with a lump in the head and neck region. Three<br />
different ultr<strong>as</strong>ound machines using different form of el<strong>as</strong>tography softwares will be used to<br />
analyse the stiffness of the lumps. When the „stress“ form h<strong>as</strong> been applied to these lumps,<br />
an el<strong>as</strong>togram can be obtained which displayed a visually colour-scale stiffness. These ranges<br />
of stiffness are recorded. The lumps will then undergo a fine needle <strong>as</strong>piration cytology for<br />
diagnosis.<br />
The results of the el<strong>as</strong>togram study will be compared to the cytology results of the lumps and<br />
bumps. This study is important to establish if ultr<strong>as</strong>ound el<strong>as</strong>tography is a reliable diagnostic<br />
tool to differentiate malignant lesion from benign lesion. As part of this el<strong>as</strong>tography presentation,<br />
a separate presentation on ultr<strong>as</strong>ound el<strong>as</strong>tography on thyroid will also be presented<br />
by my colleague Dr Hajatdoost.<br />
The data gathering for study is currently being finalised at the time of abstract submission.<br />
Results, discussion and conclusion of this study will be presented at the meeting in June<br />
2012.<br />
