Essay On Elastography

723 Words3 Pages

The technique of elastography was introduced into the clinic for the purpose of improving the diagnostic performance of thyroid carcinoma. Due to its a noninvasive nature and later on with additional imaging modality features, Ophir et al. [44] proposed elastography in 1991 for the purpose of evaluating the stiffness of tissue and it has been widely used ever since. Many studies have indicated that adding elastographic technique to conventional US can help to improve the differentiation of thyroid lesions [45, 46]. Elastography is based upon the mechanical principles that tissue displacement is more in softer tissue than in harder tissue; hence elastography can be used to estimate the tissue stiffness in way that can reflect the nature of lesions. Various studies have indicated that the increased in tissue hardness is mostly associated with a raising risk of malignancy [47]. …show more content…

Initial evaluations of these two techniques in clinical trials have indicated that they may improve the diagnostic performances of differentiating benign from malignant lesions and help to reduce the number of unnecessary benign thyroid biopsies [15, 16]. Strain elastography is a previous elastography technique; however, it requires manual compression by the operator and can only provide semi-quantitative images [17]. The second type of elastography is shear-wave elastography (SWE). SWE is the latest elastographic technique with more reproducible and less operator-dependent and doesn’t rely much on external force. SWE can measure quantitative elastographic values which can be expressed in either kPa or m/s [18 -

Pathophysiology ANAT1066 Case study assessment Case study (b) INTRODUCTION Base on the clinical and laboratory data provided, the patient is suffering from Graves’ disease, a cause of hyperthyroidism which is a type of thyrotoxicosis. Clinical manifestation of Graves’ disease (GD) includes diffuse thyroid enlargement, palpitation and hyperthyroidism (Fukishima et al 2009). Other symptoms are ophthalmophathy which result in exopthalmos (bulging of the eye), and dermopathy (oedema) (mencori et al 2014). Hyperthyroidism has some symptoms such as heat intolerance, sweating and weight loss (mencori et al 2014). Tachycardia (a faster than normal heart rate at rest) and bruit (indicate hyper dynamic circulation) are among

The Victorian Era: a time where perfection was of the upmost important. A period where the ideal man or woman was what was to be expected and anything short of that was typically looked down upon. It was a standard to look beautiful and quaint, and this ideal was especially reflected in Victorian literature. From Jane Eyre being criticized that she is plain, to Lady Bracknell pointing out that Cecily is sadly simple, a person’s viewpoint on another was crucial, and no author was able to tackle this aspect better than Robert Louis Stevenson. In his novella Strange Case of Dr. Jekyll and Mr. Hyde, Mr. Hyde’s appearance and how others view him is taken to the extreme.

Radiology is a tool frequently used in medicine. Almost everyone will have an X-ray, ultrasound, MRI, or one of any of the many other imaging techniques at some point. The use and development of various radiologic techniques have reduced the need of exploratory surgeries and given us a better idea of what is going on inside our bodies. Radiology as we know it today was was invented over a century ago by a German physicist and Professor named Wilhelm Conrad Roentgen 1. In 1895 he discovered electromagnetic radiation in in a wavelength range, or the X-Ray.

These improvements typically comes in because resolution of MSCT and MRI were not enough for forensic analysis (Thali et al., 2004). Micro-CT is basically a specialised CT with much higher spatial resolution that is very useful in analysing bone structure with patterned injury (Thali et al., 2003). Micro-MR, on the other hand, means magnetic resonance microscopy or MRM. According to Thali et al. (2004), it is very useful in analysing soft tissues injury patterns.
