Magnetic Resonance Imaging (MRI) is a safe and painless test that uses a magnetic field and radio waves to produce detailed pictures of the body’s organs and structures. An MRI scanner is a large doughnut-shaped magnet that often has a tunnel in the center. They have larger openings and are helpful for patients with claustrophobia (a fear of being in tight‚ enclosed spaces). During the MRI exam‚ radio waves manipulate the magnetic position of the body’s atoms‚ which are picked up by a powerful antenna

Alzheimer’s Disease Jennifer Wlos HCA/220 August 19‚ 2012 Dawn Tesner‚ DHEd‚ CPhT Alzheimer’s Disease Alzheimer’s disease (AD) is a progressive neurologic disease of the brain leading to the irreversible loss of neurons and the loss of intellectual abilities‚ including memory and reasoning‚ which become severe enough to forgetting social or occupational functioning. Alzheimer’s disease is also known as simply Alzheimer’s‚ and also Senile Dementia of the Alzheimer Type (SDAT). I chose

Recent advances in technology permit measurement of characteristics of the nerve fibres that make up the optic nerve. One of these is SD-OCT(Fig2)‚ a non contact‚ non-invasive method that enables physicians to obtain in vivo‚ high resolution (upto 5 microns) cross-sectional images of the retina. It is based on principle of low-coherence interferometry(Fig 3). By imaging a 3D cube of data it allows a detailed evaluation of the peripapillary area.

Baker’s Cyst Anatomy And Physiology To better understand a Baker’s cyst‚ it helps to understand the anatomy of the knee joint. A cyst is a lined sac that contains fluid. Cysts that form around joints are due to a bulging of the joint capsule. A Baker’s cyst develops from the knee joint capsule. It protrudes into the tissues in the back of the knee. Four bones come together at the knee joint: * Patella/Kneecap - The patella is a small‚ flat‚ round bone that articulates with the femur in

Last week‚ we have given the opportunity to take tour in the Davao Doctors Hospital to see the Specializations in Radiologic Technology such as Magnetic Resonance Imaging‚ Computed Tomography‚ Nuclear Medicine and etc. After seeing the different modalities‚ I felt happy because it is my first time to take a look and encounter any kinds of machine. Before‚ I was expecting that being a radiologic technologist is a hard job. But then when I had given the chance to see and know what their works are

other types of radiation‚ we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of ionizing radiation (Beta‚ Alpha‚ Gamma‚ and x-rays)‚ with the exception of the MRI‚ which uses a magnetic field rather than radiation. Radiology is classified as being either diagnostic or therapeutic. Diagnostic radiology is an evaluation of the body‚ by means of static or dynamic images or anatomy‚ physiology‚ and alterations caused by injury or

MRI is optimal in the acute setting. Magnetic resonance imaging of TBI in the subacute time frame can greatly assist in optimal patient management. Early comparative studies showed that brain CT failed to detect 10 to 20% of brain abnormalities visualized by MRI after mild TBI.(56) However‚ 48 to 72 hours after injury‚ MRI is superior to CT in detection of swelling‚ bleeding‚ brain contusions‚ and axonal injury. Magnetic resonance imaging is also more sensitive and specific for brainstem

Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will be analysed and evaluated.
