Extract of sample "Breast Magnetic Resonance Imaging"

Download file to see previous pages The breast tissue is subjected to cyclical changes owing to the fluctuations in the levels of the hormones, estrogen and progesterone according to the different phases of the monthly cycle. During the luteal phase of the cycle, the amount of progesterone increases in the body mainly due to its production by the corpus luteum. The levels of estrogen are also high. The effect of progesterone is more pronounced also due to the rise in the number of progesterone receptors in the breast during the luteal cycle. This results in the formation of fluid, an increase in the process of mitosis as well as increased synthesis of DNA in all the tissues of the breast. There is an increase in the epithelial cells of the breast accompanied by an increase in the size of the lobules and ducts in the breast. This further leads to an increase in the size of the breast as well as tenderness in the breast. These account principally for the breast symptoms of the premenstrual syndrome in females. The breast may also develop cystic characteristics in this phase of the cycle which are temporary and resolve with the end of the luteal phase. The follicular phase follows the luteal phase and the initiation of menstruation occurs. This results in the destruction of the corpus luteum and the subsequent drop in the levels of estrogen and progesterone. The epithelium of the breast undergoes reduction and the ducts and the lobules are reduced to maintain their previous normal size (Bass et al 2005; Fritz et al 2010).
The cyclical changes of the breast are important when scheduling the breast MRI. The normal breast MRI shows a generalized contrast enhancement and the strength of the signals increases in a stepwise fashion. But during the luteal phase, the increase in the hormones may result in the increased enhancement in certain areas of the breast owing to the cystic changes. ...Download file to see next pages Read More

Functional magnetic resonance imaging

...? Functional magnetic resonance imaging Introduction Functional magnetic resonance imaging or fMRI is a process of mapping brain activities by analysing the modifications in blood flow and oxygenation levels that vary according to neural activities taking place within the brain (Huettel, Song and McCarthy, 2009). With increased activities in a particular area of the brain, there is an increase in blood flow to that particular location. Subsequently more oxygen is necessary for consumption, to meet the rise in blood flow. fMRI techniques can be used for revealing which part of the brain is active (for specific mental activities) through activation maps. The basic fMRI technique, developed by Seiji Ogawa and Ken Kwong in the 1990s, makes use...

Magnetic Resonance Imaging technology

...? Magnetic Resonance Imaging Technology      Magnetic Resonance Imaging Technology Introduction Magnetic resonance imaging (MRI)technology is a type of medical imaging technique, which is applied in radiology-based visualization of internal anatomic structures and physiologic processes (U.S. FDA, 2012). The technology makes use of nuclear magnetic resonance (NMR) properties to image atom nuclei within the body. The human body is a “magnet” by virtue of the fact that it has ionic hydrogen that has a positive charge and a magnetic spin. However, this magnetic spin does not make humans magnetic because these protons spin in a haphazard manner, which cancels out the magnetic properties held by each ion (Hendee & Christopher, 1984). MRI...

Magnetic Resonance Imaging (MRI)

...?INTRODUCTION Magnetic Resonance Imaging (MRI) is one of the more commonly used imaging techniques used to aid diagnosis. It uses powerful magnets and radio waves to make images (Dugdale, 2010). However, emotional distress and lack of immobility not only lessen the quality of the resulting image, but it also causes adverse effects onto the health of the patient. Figure 1 shows an example of an MRI image from a moving patient. In such cases, use of sedation or general anesthesia is warranted to increase tolerance to an unpleasant but necessary procedure, and to expedite MRI imaging of a distressed patient (Medical Advisory Secretariat, 2003; Shellock, 2011). In fact, it has been shown that MRI images are better for children who were given...

Breast Magnetic Resonance

...? Breast Magnetic Resonance Imaging Insert (s) Breast Magnetic Resonance Introduction Breast Magnetic Resonance Imaging (MRI) is one of the non-invasive medical procedures that is increasingly being used in the diagnosis and treatment of breast cancer. Magnetic resonance Imaging involves the use of powerful magnetic fields and radio frequencies to produce computerized and detailed images of soft tissues, organs and bones, as well as any other internal body structure. Unlike some imaging techniques, such as X-ray or computed tomography, MRI does not require the use of ionizing radiation. Despite recent advances, MR imaging still has a number of limitations particularly with regard to its specificity and sensitivity. Breast Magnetic...

Magnetic resonance imaging

...? Magnetic Resonance Imaging Perfusion Introduction Perfusion refers to the passage of fluid through the blood vessels or even lymphatic system to a tissue. Thus, perfusion scanning is the process of observing the perfusion activities, recording and quantifying the results. A wide range of medical imaging modalities has emerged that utilize perfusion application in a variety of medical fields. Perfusion applications are used to assess the distribution of blood to a vascular bed. Either endogenous or exogenous tracers can be utilized to regulate hemodynamic quantities, for instance blood movement, blood capacity, and the average time it takes for the tracer molecule to be passed through the tissue, or the average time of transit (Luypaert...

Diffusion Magnetic Resonance Imaging

... The advancements in imaging modalities were able to increase the understanding about the various biological systems and how these work together in living organisms. In terms of the resolution of images, Magnetic Resonance Imaging (MRI) is considered to be one of the most advanced, mainly due to its use of magnetic field in detecting the various differences in organ and tissue densities (Jones, 2011). With the discovery of peculiar characteristics of water and how it affects the movement of molecules through diffusion, aside from relying on the magnetic field generated by various molecules in cells, the additional characteristics of particle diffusion in living cells were able to contribute to the greater advancement of the use of MRI...

...Magnetic Resonance Imaging Magnetic Resonance Imaging This is an advanced imaging technique used in the field of medicine under radiology. The technique enhances visualization of internal structures; it uses a property of nuclear magnetism resonance to visualize nuclei of body atoms. The technique uses highly powerful magnetic field to align atomic nuclei, after which the radio frequency systematically alters the alignment of these nuclei. The activity produces a rotating magnetic field, which is detectable using a scanner. The information is then read recorded and to create an image of the scanned body. The magnetic field causes the nuclei in different locations to rotate with different speeds using gradients. By the use of gradients...
