Diagnosis of placenta Accrcta in women with placenta previa using Gray scale and color Doppler ultrasongraphy.

Objective: to evaluate Diagnosis of placenta accrete in women e' placenta previa using Gray scale and color Doppler ultrasongraphy. Material and methods: 50 pregnant patient in 2nd and 3rd trimester with confirmed anterior placenta previa in all forms. Were included prospectively into this study. Gray scale trans Abdominal examination was performed to detect loss of retro placental echo lucent zone and other abnormalities suggestive of placenta accrete. Color Doppler few mapping was used to scan the whole placenta to detect Any newly formed vessels at the serosa- bladder border or the presence of abnormal lacuanae. The ultra sound findings were analayzed with reference to the diagnosis made during cesarean delivery. Results: placenta accrete and its variants were confirmed in 16 patients at time of cesearean delivery. If we considered the presens of at least one criterion to be diagnostic when using each ultrasound then gray scale would have apositive predictive value (52.9%) followed by color Doppler (70.6%) The majority of patients with placenta accrete showed multiple characteristic features on ultrasound imaging Conclusion: color dopler is useful as a complemantary technique to Gray. Scale in Early detection of placenta accrete.
