Congenital Heart Disease Congenital heart diseases are lesions‚ caused by abnormal development of the structures of the heart. This happens in the embryonic life due to environmental or unknown factors. The cause of congenital disease is usually unknown‚ but there are multifactor reasons that are incriminated. They are said to be sporadic. This meaning that it is not secluded to one geographic location. However this incidence is increased in those with a positive

the bottom‚ cooled by liquid nitrogen‚ causes the magnet above to levitate. The floating magnet induces a current‚ and therefore a magnetic field‚ in the superconductor‚ and the two magnetic fields repel to levitate the magnet. Another property of a superconductor is that once the transition from the normal state to the superconducting state occurs‚ external magnetic fields can’t penetrate it. This effect is called the Meissner effect and has implications for making high speed‚ magnetically-levitated

cases of physical deformity‚ abnormally large tongue‚ bulging chest‚ enlarged organs‚ vision disorders‚ among other things. Acromegaly is diagnosed by using blood test or imaging. For the blood test a doctor must measure the GH level of a person’s blood to determine if it is elevated. After the blood test a magnetic resonance imaging (MRI) scan of the pituitary will be done. It’ll be used to locate and detect the size of the tumor causing GH overproduction.

Schizophrenia affects thought and emotion and the person being affected loses contact with reality. It is often confused with DID‚ which is multiple personalities. Schizophrenia is better described as one personality that is broken up. It affects people’s levels of functioning and over half of the people affected have serious disabilities. However‚ today many people with schizophrenia are able to function in the world and may need to only go to the hospital periodically for treatment. Most researches

foregrounds and gives “textual prominence” (Huckin‚ 1997‚ p. 82). to the depiction of love through both a fabled lens and a scientific lens. The descriptive comparison of the symbolism “hearts and doves‚ stars and fireworks” with “functional magnetic resonance imaging” highlights how contemporary relationships are no longer a fairytale experience‚ or specifically “aren’t nearly as pretty.”

representation of a slice through the body; CAT scan. PET (positron emission tomography) Scan A visual display of brain activity that detects where a radioactive form glucose goes while the brain performs a given task. MRI (magnetic resonance imaging) A technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans show brain anatomy. fMRI (functional MRI) A technique for revealing bloodflow and‚ therefore‚ brain activity by comparing successive

However‚ these shunts block regularly and their failure is difficult to detect‚ consuming clinical time and computed tomography or magnetic resonance imaging. A shunt failure would be easy to diagnose if the ICP could be measured routinely

Imagine being able to detect diseases in your body‚ or being able to examine various tissues and determine its conditions. That is exactly what an positron emission tomography (PET) scan is used for. Unlike CT (computed tomography) and MRI (magnetic resonance imaging) scans‚ the PET scan can reveal the cellular level changes occurring in an organ or tissue. To obtain this information‚ a very small dose of a radioactive chemical‚ called a radiotracer‚ is injected into the vein of the patient’s arm. The
