Magnetic resonance imaging

Picard et. al; 2009; Fivush, 2011). Previous studies examining the neural correlates of autobiographical memory using functional magnetic resonance imaging (fMRI), have found that the hippocampus also plays critical role in autobiographical memory (e.g. Cabeza et al., 2004; Daselaar et al., 2008). Specifically, studies comparing individuals with memory disorders such as Alzihmers and Schizophrenia…

shortage -or in some instances, an overload- of the chemical neurotransmitter serotonin causes depressive disorder. However, with increased research, along with refined imaging techniques in mood disorders, experts are beginning to reject the chemical imbalance hypothesis. This is because the greater steps taken with the imaging technology has allowed neurobiologists to show what differentiates the depressed brain from the non-depressed brain (Marano, 1999, p. 30). Prior to these techniques,…

chondrosarcoma (Fisher, Williams, & Cundy, 2013). Chondrosarcoma is the second most common primary malignant bone tumor. These tumors are categorized into location, size, and pain. They are diagnosed by radiograph, computed tomography (CT) and magnetic resonance imaging (MRI). Enchondromas are a type of benign bone tumor that originates from cartilage (Bowen et al, 2011). These tumors are common in small bones and in long bones, they can be cancerous but it is uncommon. There are a few other…

because it is not fully developed and it is exposed to environmental factors. During the teenage years, the brain is in a significant and crucial time of development. Furthermore, current research, powered by devices such as functional magnetic resonance imaging, concluded that the adolescent brain has rapid growing synapses and section that are unconnected. Since the sections are unconnected, it makes teenagers more inclined to impulsive decisions. These impulsive decision can lead teens…

The world of medicine has always greatly interested me. From a young age, I had been exposed to the medical profession through my father, a pediatrician at the Children’s Hospital of Philadelphia. I was always fascinated and interested by his daily work, and enjoyed learning household medical advice from a young age, like how to more effectively prevent infection from scraped knees and similar injuries commonplace during childhood. As I progressed through school, I always felt a greater affinity…

can range from 5 to 15. This is determined by the size of surgical area which should range between 1 and 2 centimeters in diameter. The amount of microfacture holes made to the bone is predicated on the treatment area size (Cluett, 2016). Various imaging techniques are available to view preoperative and postoperative…

and to check if the body is damaged. According to the Mulcahy(1971), “On November 8,1895 a scientists named Wilhelm Roentgen discovered the most useful medical technologies we use today X-Ray(pg.73).” X-Ray machines are described as cutting-edge imaging method to visualize the inside of the human body.According to Mulcahy(1971) X-Ray help diagnose and treat illnesses or injuries in the human body(pg.73). According to x ray technicians 101(2016) there is about 101 different types of x-ray…

common foot and ankle injuries that you need to be extra careful of. Once you have a suspected injury, your doctor may examine the condition of your foot. A request for diagnostic tests such as x-rays, computerized tomography (CT) scan, or magnetic resonance imaging (MRI) may also be given so that the extent of the injury will be known. Here is a list of some foot and ankle…

forget even the simplist of things (Barrett). However, some people, known as “superagers”, are able to keep their memory sharp and remain as attentive as a 25 year old. The question now is, what differentiates the two groups of people? Using magnetic resonance imaging, a study was done that identifies a “set of brain regions that distinguished the two groups” where the regular agers experienced brain atrophy and the superagers had a brain that remained untouched from any disabilities (Barrett).…

Encephalocele Johni L. Cochran University of Cincinnati An encephaloceles is a type of neural tube defect. It is characterized by a herniation of the brain and meninges through a structural weakness in the bony structures of the skull (Tirumandas et al, 2013). There are four classifications of encephaloceles: frontoethmoidal, basal, occipital, and cranial vault. Classifications are based on the type of defect and its location on the skull. Nasal or frontoethmoidal…
