After focusing the equipment and capturing the images on digital file or film, radiology technicians review the results of their work with radiologists, and take additional views when necessary. A radiology technician may also be responsible for updating patient records and maintaining the imaging equipment itself. Radiologic technologists are radiology technicians who have progressed through continued education and training or those who acquired additional training and education before entering the field.
Klinefelter syndrome: 1  Klinefelter syndrome is caused by the presence of one or more extra copies of the X chromosome in a male's cells. 2  Males with Klinefelter syndrome typically have one extra copy of the X chromosome in each cell, for a total of two X chromosomes and one Y chromosome (47,XXY).
Females typically have two X chromosomes (XX). Males typically have one X chromosome and one Y chromosome (XY). Males with this genetic condition have an extra copy of the Y chromosome in each of their cells (XYY). Most people have 46 chromosomes in each cell. Males with XYY syndrome have 47 because of the extra copy of the Y chromosome. However, sometimes this mutation is only present in some cells. According to the National Institutes of Health, XYY syndrome occurs in 1 out of every 1,000 boys (Genetics Home Reference).
