Abstract:
We studied 54 asymptomatic postmenopausal women to characterize normal contrast-enhanced computed tomography (CT) appearance of endometrium. Endometrium was visualized in 26 out of 54 (48.1%) women, and when seen its mean short-axis thickness was 7.5 mm. The anteroposterior thickness varied directly with uterine angulation (P<.05). Endometrial attenuation was significantly less than that of the myometrium (P<.05). Endometrial thickness (short axis) and attenuation were inversely correlated to patient age and to years after menopause (P<.05). We believe that our findings will help prevent overdiagnosis of endometrial fluid or thickening in asymptomatic women.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
