X-Ray and CT-Scan are both machines which can be used to create images of the internal structure of an object. These two machines are used by doctors to accurately diagnose a patient, especially when conditions in the inner structures of a man were to be determined. Both machines are powerful, but there are some differences between them. CT-scan is a more powerful instrument compared to an X-ray. It is a recent technology, and it improves on the limitations of X-ray.
Although the X-ray produces a good image of the internal structure, CT-scan will produce a better image. CT-scan uses a rotational motion, and this makes it a good option, especially when you want your target area to be produced very clean. It can also produce 3D images of organs in the body. X-ray, on the other hand, doesn't focus strictly on the target area. Hence it can only produce two dimensional images.
A bone scan is a process whereby nuclear scanning is used to examine the internal bone structure of the body. A PET scan can be referred to as the Positron Emission Topography scan. This is a process that uses a special kind of camera and tracer to examine deep inside the body, the organs with other internal structures. The bone scans place more focus majorly on the growth of the bone and the development of diseases within the bones. The PET scan, on the other hand, places more focus on other parts of the body organs, such as the brain and the heart.
In addition, a radioactive nuclear tracer is used in bone scan in such a way that it is inserted through an IV which eventually spread through the body and make some captures when attached to the bones. For PET scan, glucose is used as a tracer. When undergoing a bone scan, it is required to take about four to six glasses of water; while a PET scan does not require any intake of fluid.
Based on recent studies, the growth hormone deficiency is the most common hormone deficiency that occurs in patients with brain cancer that undergoes intracranial radiation therapy. Most often, this hormone deficiency is diagnosed in cancer patients that experienced long exposures to high-dose radiation therapy on the hypothalamus.
Radiation-induced growth hormone deficiency can develop in various settings. However, is it mostly seen in patients with CNS tumors after undergoing localized radiation therapy for face, carcinomas of the orbit, sarcomas and nasopharynx.
Other side effects of radiation therapy include skin problems, fatigue, hair loss, nausea and vomiting, loss of appetite, and low blood cell counts.
MRI and PET Scan are two types of imaging machines which are used by the doctors in diagnosing different kinds of diseases or health conditions in the body. These machines are very useful in that they give a precise and accurate diagnostic report about a patient health issue. However, there are some differences between them. MRI is the short form of Magnetic Resonance Imaging. This machine works by using a magnetic field to get images about the nature of tissues in the body, whether healthy or unhealthy.
However, there are some instances when an MRI will not be used for a patient; this is left for the doctor to decide. PET Scan, on the other hand, is the acronym for Positron Emission Tomography Scan. This machine helps in the measurement of emitted positron molecules like nitrogen, oxygen, and carbon. More diagnostic results can be generated using a PET Scan than when MRI is used
Some may assume that the MRI and the CT Scan are the same because of how they are used, but there are certain differences that should be noted. The CT scan makes use of X-rays in order to get images of the inside of the body while the MRI will use magnetic fields and radiofrequency so that the images of the body’s internal organs will be shown.
CT Scan still uses radiation while the MRI does not use radiation. The CT Scan can be used to see the full body in general while the MRI can be used for some specific portions of the body, particularly the soft tissues. The MRI is considered to be safer but is also more expensive than the CT Scan.
The best way to prepare skin for electrode application that I could find was to shave the hair the day before if necessary, and wash the skin with a damp towel or alcohol swab before drying the area off thoroughly. This will ensure that the electrodes don’t stick uncomfortably or pull at the hairs on the area the electrodes will be placed.
One other thing you want to do before placing electrodes on someone’s skin is to make sure there are no abrasions or cuts. Electricity takes the fastest way to the ground. If there’s an open sore or abrasion, it’s fewer layers of skin to go through. The electricity will prefer that and the patient may become uncomfortable before the data is taken.
An abdominal aortic aneurysm, or AAA, is a localized enlargement of the abdominal aorta such that the diameter is more significant than 3cm or more than 50% larger than normal diameter. An aneurysm usually causes no symptoms except when ruptured.
As abdominal aortic aneurysms grow, they may become painful and lead to throbbing feelings in the abdomen or discomfort in the chest, lower back, flank, abdomen, or groin. Degenerative vascular pathology is the study of the abdominal aortic aneurysm. It dramatically affects the focal dilation of blood vessels.
The initial reaction of the SNS though would increase blood pessure to try to cope for the rupture because it is the body's initial defense mechanism and then following would be a decrease in blood pressure because the body cannot keep up. This question should be modified because increased BP could be an answer if it is vague.
All of the above conditions can cause temporary reversible ECI. These include the presence of CNS depressants. There are a wide range of CNS depressant that include diazepam, meprobamate, mecloqualone, methaqualone, and barbiturates. Apart from that, Hypothermia can also be a leading cause where the temperature is less than approximately 32 degrees Celsius.
Furthermore, cardiovascular shock is another condition that can cause temporary reversible ECI. Other causes include severe metabolic disorder and endocrine disorder. This condition is also common among newborn babies that have neurologic birth defects/injuries. There are many other causes that are still being discovered by medical researchers.
