While diagnostic imaging is likely the most widely recognized (e.g., obstetric sonography) application of medical ultrasound, therapeutic ultrasound predates diagnostic medical ultrasound by at least two decades with the earliest investigation of focused therapeutic ultrasound reported over 60 years ago; study of lesion formation in ex vivo beef liver and in situ brain of cats and dogs). But despite its early start, medical applications of therapeutic ultrasound waned due to the lack of adequate imaging for targeting and monitoring of treatments. (Smith, 2001) However, with recent advances in imaging, therapeutic ultrasound is making the resurgence in the medical community. High-intensity focused ultrasound (HIFU) is such a therapeutic application, with intensities that are generally 1,000 to 10,000 times greater than traditional diagnostic ultrasound devices ( Table 1) for the purpose of selective destruction of tissues deep within the body. In its clinical application, acoustic energy is focused on a well-defined region of tissue (focal region or zone), and the energy that has not been scattered is absorbed and converted into heat. (Soneson, 2009) Due to the high intensities in the focal region, temperatures quickly rise to levels that will result in rapid cellular necrosis, creating a well-defined region of necrosed tissue while leaving the surrounding tissue undamaged.This lesion may be on the order of one to a few centimeters in length and one to a few millimeters in diameter.
Tjie essay "Risks associated with ultrasound procedure" concerns the phenomenon of ultrasound and its impact. Reportedly, ultrasound is the mechanical transmission of energy all the way through a medium at a frequency above the upper limit of human hearing…
Directly administering fluids and medications into the vein is known as intravenous administration and means that the patient receives the effects of the treatment much faster than by other methods of administration (Intravenous cannulation, n.d.). A patient may also need a cannula in an emergency situation (Paramedic Centre, 2011).
It is an extensive filed that deals in association to computer science, computer vision, electrical engineering, mathematics, physics, and perceptual psychology. Creation of a visual image is a controversial issue in the society that poses impact on the health of an individual (Goroll & Mulley, 2009:550).
However, those that wish to pierce should be aware of the risks before making that choice.
Oral piercings are piercings of the tongue, lips or cheek. During the past few years, oral piercings have become a type of individual expression. The history of tongue piercing goes back to the ancient Aztec and Maya cultures but these have often been temporary piercing for religious and performance practices.
This group also includes patients with HIV infection, at risk for more severe illness if they get infected with MRSA. The present article analyses the incidence and risks for MRSA bacteraemia in HIV population.
HIV infected patients are at amplified risk for Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus (MRSA) colonization, infection and blood stream infection.
This lure for beauty enhancement through plastic surgery can most certainly make an individual look and feel younger and more vibrant, and many of these procedures have positive outcomes at the aesthetic and emotional level. However, even
In case of DVT in pregnancy, the problem is further complicated by its diagnosis and management, in that due to the risks of fetal exposure the imaging studies have limited roles. This may lead to delayed diagnosis, and the management of an established DVT is widely debated due
Creation of a visual image is a controversial issue in the society that poses impact on the health of an individual (Goroll & Mulley, 2009:550). The science of image creation has a range of links that include
The purpose of this paper is to examine the possible biological risks and hazards that are associated with these three methods when imaging a pregnant patient. This will be done by the examination of the scientific
