Turner Syndrome : Tests

Turner syndrome can be diagnosed at any stage of life. It may be diagnosed before birth chromosome analysis is done during prenatal testing. The doctor will perform a physical exam and look for signs of underdevelopment. Infants with Turner syndro...

Turner syndrome is diagnosed on the basis of genetic analysis of chromosomes. This can be done prior to birth. However, the predictive value of amniocentesis in diagnosing Turner syndrome varies from 21-67%. There is no significant relation betwee...

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body) Palpation (feeling the body with hands) Auscultation (listening to sounds) Percussion (producing sounds)

Karyotyping is a test to identify chromosome abnormalities as the cause of malformation or disease. This test can: Count the number of chromosomes Look for structural changes in chromosomes The results may indicate genetic changes linked to a disease.

Karyotype refers to the arrangement of chromosomes in their matched (homologous) pairs. For the purposes of this definition, we will be referring to human chromosomes, although there is a karyotype characteristic for each species.

A chest MRI uses powerful magnets and radio waves to construct pictures of the body. Unlike conventional radiography and computed tomographic (CT) imaging, which make use of potentially harmful radiation (x-rays) that passes through a patient to generate images, magnetic resonance imaging (MRI) is based on the magnetic properties of atoms. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The subtle differing characteristics of that signal from different tissues enables MRI to differentiate between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging plane, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones, however, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images.
