Endometrial blood flow analysis in postmenopausal women: can it help differentiate benign from malignant causes of endometrial thickening?

abstract：:Radiographic analysis of 33 cases of trisomy 9p (21 familial, 12 nonfamilial) disclosed consistent abnormalities in the hands, feet, and pelvic bones, with one exception (subsequently considered a misdiagnosis). Most of the abnormalities were present only during the period of epiphyseal growth and occurred with simila...
