Ct Scan Vs X-Ray Scan

929 Words4 Pages

A CT scan, CT standing for computed tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI machine does not use X-rays to make photos. MRI scans take much longer time t produce a detailed photo and is a lot more noisy than CT scans. Another difference between MRI scans and CT scans is that CT scans are suitable for bone injuries, lung and chest imagining and cancer detection. While MRI scans are suitable for soft tissue evaluation, e.g., ligament and tendon injury, spinal cord injury, brain tumors, etc. …show more content…

These cells respond to the mechanical sound vibrations by sending electric frequencies. The human ear, that is healthy can hear sounds ranging from 20Hz to 20,000Hz.Over time the hair like cell stereocilia may wear out and become damaged. As a result, this can cause hearing damage. Sound pressure is measured in dB and a average person with good hearing can hear down to zero dB, people with extremely good hearing can hear down to -15dB. When a sound reaches 85 dB or stronger damage starts to happen to the hearing of a person. The amount of time that you are exposed to loud noises also affects how severe the damage will be. If you are exposed to loud noises for a long time there is a very big chance that you get ear damage. Most people underestimate how loud sounds can be, a regular conversation can reach up to 60 dB, which does not cause any damage. However a personal sound machine can easily reach up to 100 dB which can cause damage to your ears in just 15

2015). In Australia between nine and 12 children per 10,000 births will be born with a moderate or greater hearing loss in both ears and a further 23 children per 10,000 will acquire a hearing impairment that will require hearing aids by the age of 17 (Australian Hearing 2013). Within the Aboriginal and Torres Strait Islander communities it is estimated that 30-80% of indigenous children will suffer from some form of hearing loss. Ear disease and hearing impairments is a significant problem in developing countries and among many of the indigenous populations, especially in Australia (Burrow et al. 2009). Although middle ear disease or Otitis Media (OM), an inflammation of the middle ear, typically leads to conductive hearing loss there are rare cases leading to high frequency sensorineural hearing loss after repeated exposure (Burrow et al. 2009; American Speech-Language-Hearing Association [ASLHA]

Radiology is a unit to where patients will get different scans such as x-rays, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), fusion imaging, and ultrasound. Radiologist, on the other hand, is a doctor who is specialized in treating disease and injury through the use of medical imaging. This unit diagnosed hidden injuries, internal bleedings and etc, by doing a scan thoroughly with his body, focusing in his organs and abdomen. Contrast is used to improve the visibility of internal bodily structures. Jamey injected a contrast in the patient’s body that will travel through his bloodstream and lighten up tissue in the body.

For the newborn twin, Chris and his wife want their child to have a successful life through hearing.

Hearing loss can be categorized by which part of the auditory system is damaged. There are three basic types of hearing loss is conductive hearing loss, sensorineural hearing loss, and mixed hearing loss. The degree of hearing loss refers to the severity of the loss. The common classification is normal, moderate and severe/profound. The configuration of hearing loss refers to the degree and pattern of hearing across frequencies.

The topic of cochlear implants is causing quite the argument between the deaf and medical community. The core of the disagreement centers around whether or not cochlear implantation should continue to be considered as an option for hearing impaired individuals to improve auditory ability.. According to the American Speech-Language-Hearing Association a cochlear implant is “a device that provides direct electrical stimulation to the auditory (hearing) nerve in the inner ear.” Proponents of cochlear implants claim that hose who are born with or later experience a problem with the sensory nerve of the inner ear have the opportunity to gain the ability to hearHowever, many are now arguing that this device is not as useful or healthy for the human ear as it has been said to be. Those who oppose cochlear implantation, namely the deaf community, view it as a threat to the deaf community and its culture.

Hearing loss simulation As a student at Santa Ana College, I have had the privilege to embark on a wonderful exercise where I can experience hearing loss for a short period. In this particular task, I started with the preparations as first to insert one earplug in each ear for the duration of thirty minutes. Also as intended for this simulation, I am bound to insert both earplugs in each ear for the duration of thirty minutes. As a participant of this project, I will endure this for a total of an hour and thirty minutes. I feel that this will be challenging for me because I love to listen to music and talk on the phone.

I do agree with what the writer is saying that headphones are damaging ears by all of the technical properties that are put into this so that headphones can allow you to hear. I also know from experience that listening with headphones too long can make a slight problem with your hearing. I agree that parents should definitely limit younger kids contact with headphones because if they don’t hearing loss will most likely occur. This article needs more proof and examples to go with it or people are not really going to get the point to why we need to limited headphone

The first benefit is pay, on average a radiologist will make around $280k (pay scale). The next benefit in the potential to work from home, a radiologist can remote into a hospital network from home to read exams and give reports for stat exams for other doctors in an emergency situation. The next benefit comes from my interview with Dr. Ludka and when asking him about the benefits he told me “a benefit in my opinion is that there is no routine exam, meaning there is no two test are exactly the same and that makes so work doesn’t get boring” (Ludka). A fourth benefit is they have a direct impact in the patient’s wellbeing if they had diagnostic test done then the radiologist must read it in order to discover the patient’s condition and without accuracy a patient could potentially die depending on their condition. A final benefit is some of the extra perk that a radiologist get, with my interview with Dr. Wong I asked him about benefits and his answer was “working as a radiologist, we typically get more vacation time than any other doctor”

Sound is measured in units called decibels. The sound of a quiet room at night is measured at approximately 20 decibels. However, the maximum volume of sound on some MP3 players as well as loud music that is played at various nightclubs is measured at 110 decibels. Many ear specialists claim that exposure to noise levels above 85 decibels can damage hearing and cause hearing loss. This is because loud noise, which includes loud music, damages and eventually kills the hair cells in the cochlear because of the movement of the sound waves inside the ear that causes the structures namely, the hair cells in the cochlear to move violently.
