Encyclopedia updated live from wikipedia, last check: october 09, 2012 06:38 utc (49 seconds ago) from wikipedia, the free encyclopedia elastography is a non-invasive method in which stiffness or strain images of soft tissue are used to detect or classify tumors. A tumor or a suspicious cancerous growth is normally 5-28 times stiffer than the background of normal soft tissue. cheap viagra from canada When a mechanical compression or vibration is applied, the tumor deforms less than the surrounding tissue. discount viagra online I. generic viagra tadalafil 20mg reviews E. viagra for sale fast shipping The strain in the tumor is less than the surrounding tissue. Hence a strain image may, under particular simplifying assumptions, be interpreted as representative of the underlying young's modulus distribution. do you take viagra everyday Medical imaging ultrasonic imaging is the most common medical imaging technique for producing elastograms. how can i get viagra over the counter Some research has been conducted using magnetic resonance elastography (mre) and computed tomography. However, using ultrasound has the advantages of being cheaper, faster and more portable than other techniques. discount viagra Transient elastography is used for example to measure the stiffness of the liver in vivo (fibroscan, echosens, france). Viagra 50mg ohne rezept It is an alternative noninvasive method to liver biopsy. mechanism of viagra action A correlation between liver elasticity and the fibrosis score (or cirrhosis) has been shown. [1] siemens tissue strain imaging acoustic radiation force impulse (arfi) imaging is another imaging modality being researched to non-invasively characterize liver stiffness [2] [3] mathematical description pre-compression images are correlated to post-compression images, resulting in regions of large and small change in position. This is called the shift-diagram. The derivative of the shift will produce the strain diagram. buy viagra canada References ^ ganne-carriã© n, ziol m, de ledinghen v, et al. (2006).
