Magnetic resonance imaging

human trials. Volunteers are given an extremely small one-time drug dose, while refined imaging techniques monitor how the drug behaves in the body. Microdosing can replace certain tests on animals and also aid in screening out drug compounds that are incompatible in humans so that they won’t look towards government-required animal testing. Functional magnetic resonance imaging (fMRI) is an advanced brain imaging and recording technique that can substitute primitive experiments where rats, cats,…

cruciate ligament (ACL) tears. When a person suffers a potential injury they must be diagnosed by a qualified healthcare professional prior to deciding on an intervention to correct the tear. There are many different methods of diagnosis: magnetic resonance imaging (MRI), arthroscopy and clinical tests. There are three clinical tests that are commonly used which are the pivot-shift test, drawer, and Lachman’s test. The patient’s socioeconomic status, prior level of function, and desired…

they do not use radiation unlike many other forms of medical imaging, these means it can be used for all ages with no threat of being exposed to radiation. The MRI scans are relatively painless, and they also show unique information other methods are unable to find. However, like all the other methods mentions this isn’t one fits all method, and has some problems such as that you are unable to have anything that can be effected by a magnetic field with you such as any metals, hearing aids,…

neuroscience is the mechanisms of the brain and nervous system when involved in memory, thinking, and other cognitive processes. Jake’s anxiety comes from the way he thinks. Scientist under this field use things like magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET) to record the activity of the brain. The therapist may be able to see from x-rays that Jake’s neurons are out of control. The psychologist would then send Jake to…

electromagnet form a magnetic field. Electricity is used to constantly reverse the poles of the electromagnet. When the poles switch, it causes a disruption in the magnetic field, which makes vibrations. These vibrations are then made into sound. Another device that utilizes is the MRI (magnetic resonance imaging) machine. MRI devices use powerful doughnut-shaped electromagnets to create a magnetic field around a patient’s body. The charges in the atoms of the patient’s body respond to the…

Virchow-Robin (VR) spaces or perivascular spaces of the brain refer to spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. A few evident perivascular spaces can be considered normal at any age but many visible perivascular spaces are not. The relevance of visible perivascular spaces to SVD is shown by their presence in increased numbers in patients with white matter hyper-intensities and with symptomatic lacunar ischemic stroke. The…

currently the leading cause of death after skin cancer in women. Women over the age of 40 are highly encouraged to have a yearly breast exam done. This usually includes a clinical breast exam and imaging the breast for any signs of tumor using devices such as a mammogram, ultrasounds and magnetic resonance imaging (MRI) devices but there is some question about the efficacy of these…

For a few years all researches have been agreed that the behavior and the human mind, in normal and pathological conditions, are directly related to the function of nervous system. Also psychiatric disorders of affective or cognitive origin are interpreted as the consequence of a particular pathology of the nervous system. Therefore, neuroscience involves all the different branches of psychology that have the suffix “psych”, as for example psychology, psychiatry, psychopathology. All these…

Hi Patry, Thank you for sharing your notion about “recurrent acute episodes of low back pain”. According to Shinichi et al. (2016), ninety percent of adults will have an episode of low back pain (LBP) in their lifetime, moreover about 24-87% will experience the recurrence of the LBP a year following the acute bout. Petersen and Lystad (2016) presented a case report about a 48-year-old male police officer, complaining of acute LBP of two weeks duration. Two months later after the first episode…
