Becker muscular dystrophy: carrier detection by real-time ultrasound

The applicability was tested of real-time ultrasound imaging to the high musculature for the carrier detection of Becker muscular dystrophy (BMD). A total of 17 obligate carriers were examined. Ultrasound images in 3 patients, aged between 46 and 59 years, showed moderate differences compared with the controls. In 3 other obligate carriers, aged between 46 and 71 years, only doubtfully abnormal findings could be made; ultrasound images showed no differences in 11 BMD carriers aged between 10 and 47 years. In women aged over 40 years, compared with adequate controls of the same body type, real-time ultrasound imaging may provide additional evidence and thus help in the detection of BMD carriers.
