Why Is Occipital Lobe Important

When damage to certain regions of the brain occurs, conditions may develop where one is able to register visual information but incapable to distinguish anything (Anderson, 2009). Consequently, difficulties with visual impairments can include an inability within the brain to interpret and or process visual information (Anderson, 2009). Thus, visual perception impairments or disorders typically refer to the inability to make sense of information received through sight (the eyes) (Weiten, 1998). One such visual perception disorder is visual agnosia.

One of the biggest advantages of MRI equipment is that it can be used to diagnose medical conditions in the heart, breast, bones, spine, and brain. This is the only imaging equipment, which can be used to diagnose issues, in all the above-mentioned parts of the body. The equipment can be used to identify stroke and blockages in the circulatory system, cardiovascular conditions, tumors, and injuries. There is an excellent return on investment in the MRI because of the variety of uses it has in a clinical setting (Keefer, 2011).

* Ultrasound. An ultrasound uses high-frequency sound waves to generate images of your internal organs, such as your kidneys and bladder, on a computer screen.

You will be provided with a signed requisition from your doctor which is to be brought with you for your appointment.

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

Two brain structures that could likely be affected by this damage are the frontal lobes and the temporal lobes. The frontal lobe produces speech, controls motor skills, and initiates leading functions such as thinking, personality, emotion and memory. (Huffman, K., Dowdell, K. 2015. Pg. 71). The temporal makes it possible for an individual to hear properly, comprehend language, recollect thoughts, and maintain emotional stability; this lobe also contains the auditory complex, which is responsible for the interpretation

The doctor also questions the patient about the symptoms, their duration, and their onset. In a Physical examination, the doctor runs tests that will determine the health of nerves and muscles. Doctors will also look for weakness in specific parts of the body. In a MRI, a patient’s body is placed within a magnetic field and scanned by radio waves. Doctors also take pictures of the brain or spine to see if there are any patches or scars on the myelin sheath. In CSF collection, the doctor will take a sample of the patient’s spinal fluid. Then doctors study the sample for abnormalities like an increase of white blood cells and high amounts of immunoglobulin G. In ERTs, doctors attach wires to a patients scalp. Then doctors can measure the speed of visual, hearing, and sensory pathways and can detect damaged areas of the brain.

To have their symptoms diagnosed, a person must first seek medical treatment. Only 20-25% of patients who are admitted to the hospital with a stroke arrive in the emergency department within 3 hours of the onset of symptoms (3). Once a doctor is able to determine what kind of stroke has occurred, it is important the appropriate medicine be given. If the wrong medicine were given to treat a stroke victim, it could result in death. Treatment for an ischemic stroke will focus mainly on restoring blood flow

Neuroradiological imaging plays an important role in the process of diagnosing ischaemic stroke. The different imaging modalities that can be used to diagnose ischaemic stroke include computed tomography (CT), magnetic imaging resonance (MRI), and radionuclide imaging. In this article, the different modalities that contribute to the diagnostic process are discussed, with a focus on CT scan protocols.

Other portions of the brain that were shown to be affected by the MRI scans include, the tomporal lobe, frontal lobe, and insular cortex. These brain areas have all

The parts of the brain that are most at risk for traumatic brain injury are the frontal lobe and the temporal lobe. This may be attributed to the fact that they are up against rigid bone. The structure of the skull positioned anterior to the neck allows for greater distances and variances of movement. The frontal lobe influences personality, planning, initiating, and organizing; all of which that are needed for high level cognitive functioning. Damage to the frontal lobe may result in changes in an individual's personality and lower level organizing. Moreover, the temporal lobe is

Venography – this test is a special x-ray and more accurate than the ultrasound. A radioactive dye is injected into the vein to help illuminate the blood clot.

location of the frontal lobe in the brain, it is at high risk of damage, in head trauma case to the

The temporal lobes are located on the side of the head and are responsible for important functions such as hearing, memory, emotion, and language. Life would be very difficult with temporal lobe damage. Difficulties in speech could develop because of the disturbance in language comprehension. Therefore making it hard to express ideas and thoughts. If severely damaged it could affect your hearing, memory, and emotions. Hearing loss could impact your ability to socialize with others in a group setting. Therefore, making it very unpleasant to socialize and meet new people. Also, having difficulty with memories because of temporal lobe damage would make learning something new very difficult. Life would be a lot more challenging with damage

An MRI (magnetic resonance imaging) is a scan that uses a system of techniques, involving magnetism, radio waves and a computer to generate detailed images of the human body. Essentially, it is a tube encased by a large circular magnet. The patient would be placed on a moveable bed, which is then inserted into the tube. The magnet then creates a strong magnetic field that aligns the protons of hydrogen atoms. These hydrogen atoms come from the human body, which is 50-65% H2O. These atoms are exposed to a beam of radio waves. This spins the various protons of the body. As they spin, they produce a slight
