Functional magnetic resonance imaging

I. Introduction: The purpose of the case study is to determine which of the patient’s cranial nerve(s) are damaged. The human brain and brain stem contain eleven pairs of cranial nerves to the neck and head, and one pair of cranial nerves to the abdomen and thorax. Each cranial nerve is numbered by a Roman numeral and in sequential order from cranial to caudal: (I) olfactory nerve carries sensory information to the brain and is responsible for the nose; (II) optic nerve carries sensory…

Computed tomography (CT) is a computerized method that uses a computer to process the data collected from the passage of x-ray beams through the region of interest. The multislice CT (MSCT) means CT that the system equipped with multiple rows of CT detectors to create images of multiple sections. The data obtained from the patient will be transformed into “cuts” or cross-sectional slices of the human body (Romans, 2011). In early 1970, they use a single slice CT scan that contributes too many…

element in the identification, diagnosing, and treatment of many types of medical conditions” (http://www.healthline.com/health/x-ray#Overview1 ). Over the next century, Roentgen and others who followed his work would introduce new modalities of imaging and also drastically improve the efficiency and safety of these modalities as well. One modality that has significantly improved upon the two-dimensional x-ray is known as Computed Tomography. This modality gets its name from the idea of…

is a medical imaging method that combines multiple X-ray projections taken from different angles to produce detailed cross-sectional images of areas inside the body. CT images allow doctors to get very precise, 3-D views of certain parts of the body, such as soft tissues, the pelvis, blood vessels, the lungs, the brain, the heart, abdomen and bones. CT is also often the preferred method of diagnosing many cancers, such as liver, lung and pancreatic cancers. Magnetic Resonance Imaging (MRI) is…

medical profession. Along with other forms of medical imaging, radiology has changed how diseases can be measured, managed, diagnosed, and treated. The various modalities of radiology provide for clearer and more efficient results, less invasiveness and quicker recovery times, and less costly ways to diagnose and treat patients. Each modality of radiology has different imaging capabilities, which provides for clearer and more efficient results. Imaging modalities have varying complexities that…

correct major aesthetic deformities or both (Pompili et al., 1998). Today, three-dimensional (3D) models of anatomical structures can be constructed based on anatomical information from scanning data coming from computerized tomography (CT). Magnetic resonance imaging (MRI) data is used to 3D modelling of soft tissues and computerized tomography (CT) for Hard tissues (i.e. bone) of the human body. The fact is face is a symmetrical structure, so abnormalities on one side of the face or skull…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

Numerous studies have been conducted on MRI being a useful tool in prenatal imaging of the posterior fossa. Gurbaud (2004) suggests that MRI is useful as a complementary investigation to US in three particular situations. Ranchod, Androniko, & Modi, (2012) detail 4 case studies where MRI was used to diagnose specific posterior fossa abnormalities after having an US. This paper examines research done to examine the posterior fossa in prenatal brains with the use of US and fetal MRI. Literature…

office and preparing the patients before getting an MRI. Working in the front is a great job, but it is a means to an end for me. I need something more challenging, something that catches my interest and will keep me on my toes every day. Magnetic Resonance Imaging is what I want to do, as I started to research going to school and talking with my coworkers The Gurnick Academy is what caught my…

magnets. When the magnetic field makes the spinning protons wiggle, the stronger the magnetic field, the faster the wiggle. Nuclei wiggle at roughly 50 million times per second. If a proton is excited by some energy like a radio wave it will send that energy back as a radio signal that is slightly detectable. A MRI is basically a strong magnet, radio transmitter and receiver, as well as electronics to organize or coordinate their operation. The magnet creates the strong magnetic field, stronger…
