Understanding MRI Scan, benefits, diagnosis, sideeffects

 

MRI stands for Magnetic Resonance Imaging. It's a diagnostic procedure that provides detailed pictures of the inside of the body using a powerful magnet, radio waves, and a computer.

An MRI uses very strong magnetic fields to align all nuclear spins. It then sends an RF pulse that flips tissue's natural polarization bias in different axes which refocuses protons magnetically along pre-determined axes of alignment. By flipping their inherent spin orientation during the readout process, scientists are able to create images presenting how molecules are oriented within living tissue or at specific points in time after an event has occurred. This technique is known as magnetic resonance imaging (MRI) because it causes nuclei atoms to respond with varying intensity to externally applied electromagnetic fields following established.

What tests are used to manage anemia and what do they mean?

  The doctors   use a number of tests to diagnose anemia. Hb (hemoglobin) is one of the key indicators used in diagnosis. A hemoglobin test is a blood test that measures how much hemoglobin you have in your red blood cells. A hemoglobin test is generally used for detecting: In addition, a hemoglobin test can also be carried out to assess bone marrow's response to treatment, evaluate possible blood donation and check the levels of red blood cells in the body. There are certain conditions that may interfere with the results of the  hemoglobin test.  In such cases, it is recommended to get the test done again. For the hemoglobin test, a sample of your blood is taken and tested in a clinical laboratory [read more about the process here]. The results are expressed as grams of hemoglobin per deciliter (g/dL) or micrograms per liter (mcg/L). Normal range for this test is 12g/dL - 18g/dL (12.1-18.0 g/L) for adults and 9g/dL - 13g/dL (9.0-13.3 g/L) for children. If the test r...

Is There a Link Between Vitamin E Capsules and Breast Enlargement?

Image
  Vitamin E capsules are often marketed as a natural way to increase breast size. The theory is that vitamin E can help regulate hormones, which in turn can lead to breast growth. However, while there is some evidence to suggest that vitamin E can help to regulate hormones, there is no scientific evidence to suggest that it can lead to breast growth or enhancement. In fact, some studies have suggested that taking high doses of vitamin E may actually have negative health effects.   Breast enlargement supplements, capsules, and tablets are another popular option for those seeking to increase their breast size. These supplements often contain herbal ingredients such as fenugreek, saw palmetto, and wild yam, among others. The idea is that these ingredients can stimulate the production of estrogen, which can lead to breast growth. However, while some studies have suggested that these herbal ingredients may have some estrogenic effects, there is little evidence to suggest that they...
