Ultrasound Elastography Applications
Ultrasound elastography is the use of ultrasound to produce measurements or images of tissue stiffness. Several different approaches are used, but all rely on creating some form of displacement of the tissue and measuring the response. Ultrasound elastography can be implemented in a number of ways; from simple add-ons for conventional ultrasound scanners, to dedicated ultrasound elastography units. Different techniques are used to generate the results, depending on the particular approach and clinical application.
Ultrasound elastography is a new ultrasonic imaging technique introduced to produce images of the Young's modulus distribution of compliant tissue. This Young's modulus distribution is derived from the ultrasonically estimated longitudinal internal strains induced by an external compression of the tissue. The displayed two-dimensional images are called elastograms.
Tissue strain analytics could represent the most important development in ultrasound technology since the advent of Doppler imaging. Tissue Strain applications provide a new dimension of diagnostic information through either qualitative assessment or quantitative measurement of the mechanical stiffness of tissue. Tissue strain analytics compliments conventional ultrasound exams by providing an extra dimension of information - mechanical stiffness. This additional information can be combined with anatomical (B-mode) as well as vascular (Doppler) information such that the actual diagnosis is contained by the intersection of three dimensions of information.
In order to produce ultrasound elastography images or measurements, the tissue to be assessed are stressed by the application of a force. This force may be applied by the operator, an external mechanical device, physiological motion, or by the ultrasound probe itself in the form of acoustic waves. The response of underlying tissue structures to such stress varies according to tissue stiffness. Perhaps the simplest form of ultrasound elastography is to acquire data before a stress is applied. By comparing these two sets of data, it is possible to derive a 'stiffness' measure. A stiff object will tend to move as a whole, whereas soft tissue compresses more unevenly, with tissue closer to the applied force compressing more than those further away.
Ultrasound elastography has been most frequently used in the assessment of liver fibrosis in a non-imaging, quantitative capacity, but in recent years the technique has been investigated in a broad array of clinical applications. Of particular note is the potential of ultrasound elastography in the assessment of liver fibrosis and in breast imaging. These subjects have been the subject of a significant body of research and were the primary focus of this review. Other clinical applications for which the ultrasound elastography technique has been investigated include: endoscopic, vascular and prostate imaging, which were briefly reviewed for this evaluation, as well as thyroid, skin and brain tumors, which were outside the scope of this review.
Clinical research has shown very promising results in differentiation between benign and malignant tissue in thyroid gland, breast, and prostate and to assess liver fibrosis.
Also, endoscopic ultrasound elastography is a new application in the field of the endosonography and seems to be able to differentiate benign from the malignant nodes and pancreatic lesions with a high-sensitivity specificity and accuracy. Ultrasound elastography is superior compared to conventional B-mode imaging and the interobserver reproducibility is satisfying.
Intravascular ultrasound elastography is a promising tool for studying atherosclerotic plaque composition and assessing plaque vulnerability. Current ultrasound elastography techniques can measure the 1D or 2D strain of the vessel wall using various motion tracking algorithms. Since biological soft tissue tends to deform non-uniformly in 3D, measurement of the complete 3D strain tensor is desirable for more rigorous analysis of arterial wall mechanics. Atherosclerotic plaque rupture is the major cause of acute coronary syndromes. Currently, there are no reliable diagnostic tools to predict plaque rupture. Knowledge of plaque mechanical properties based on local artery wall strain measurements would be useful for characterizing its composition and predicting its vulnerability.
Currently, a quiet revolution is occurring in diagnostic ultrasound, the results of which are benefiting all ultrasound practitioners. Smaller, portable machines are becoming available, image quality is dramatically improved, real-time imaging is now possible, and solutions are being found for those patients that were previously difficult to image.

HP Officejet 5610 All-in-One Printer-What You Should Be Aware Of Before Purchase
Many people including me an ultrasound tech have printers at home. I have spent a significant part of my ultrasound technician salary in printers. The most of them just work not as well as I expected. I think you may also have the similar experience. Recently, with the recommendation from my good friend, another ultrasound technician graduating from one of the top ultrasound technician schools, I bought a HP Officejet 5610 All-In-One Printer. In the following paragraphs I reviewed this model and I hope this short article can help you make good purchase decision. The HP Officejet 5610 All-in-One Printer is one of HP's most inexpensive printers that has features such as copying, faxing and scanning. This can be very useful for a lot of people such as anyone who works at home, students or just ordinary users. The HP Officejet 5610 has a few flaws as well. This article will look at some of these so that you will know about them before you make a purchase.
It is important to note that modern-day printers are multifunctional units, capable of doing much more than printing a few docs in black-and-white.
Printing everything from labels to photos, the HP 5610 is a very complex printer that has many different functions and uses. Whether you need to print labels, or envelopes, for your small business, this printer can do this quickly and easily. You cannot, however, print on paper that's any larger than 85 x 14 inches, so this isn't the right printer for you if you have the need to print out larger documents such as posters. However, for most everyday or small business needs, the HP 5610 gives you many options.
With a printer like the HP 5610, that's priced quite reasonably but still has a good number of features, some business owners might be wondering if this model is sufficient for their needs.
The answer really depends on the type of business you have and what you need a printer for. The HP 5610 is ideal for a small business owner, or someone that needs an average all-in-one system that can fax, copy, and print at ordinary speeds. More expensive models that can handle medium to large sized business production would probably be more apropos than using this low-cost but versatile all-in-one printer.
Although the HP Officejet 5610 has many different functions, it may not be helpful for everybody. If you are a photographer who needs to capture high quality prints, then you will not particularly like this printer. This printer also does not have a lot of the networking attributes that other more advanced printers have. This is something that you should remember if your company has more than one computer. Also, this printer fails to have wireless network support. This printer is better when used for common use and not specialized use. These are few things that indicate that this might not be a good choice for all printer users. But, this printer is a good fit, if you are looking for a multi-functional printer that does a great job with the basics. To conclude, anyone that buys the HP Office Jet 5610 All-in-One Printer may experience a few problems, but in the end, because of the price, it is an exceptional buy. People that may make a copy or two once a week will definitely get their money's worth with this all-in-one combination printer. Those that have a small business will definitely find this printer very useful. This printer, unfortunately, may not work for you if you do a lot of printing, faxing, printing, and copying every day for your medium-sized business.
What type of scans are these?!?
I've had 3 scans cos I had reflux (vesico Ureter) and now have a a deformed kidney. I know one was an ultrasound (with the cold jelly stuff) for the other two I had radioactive dye put into my blood stream. Then for one I was sat in front of a scanner thing with a screen around me, then they made me urinate into a bedpan to see how it went through. For the other dye one I was told to lie on this big machine, then another big part of it came down and squished me.
What are they?! CAT, MRI? I have no idea what they mean?
The one where the dye is injected is done in nuclear medicine, where they use a gamma camera to see the size and shape of your kidneys. It is called a DMSA scan. The other one is called a voiding cystogram, where they can see if all the urine comes out of your bladder without going back up to your kidneys. It's also to make sure you can empty your bladder completely. Hope this helps!
