Aims and objectives
Aim: To discuss types of Invasive Placental Disease (IPD) To describe the features of US and MRI in diagnosing IPD To calculate the sensitivity of US Vs MRI with the gold standard intra operative findings To calculate other statistical parameters by comparing US and MR findings To see how MRI can be used as a problem solving tool in equivocal cases Background: Invasive Placental Disease (IPD) occurs when there is a defect in the decidua basalis,
resulting in an abnormal invasion of the...
Methods and materials
A retrospective study was conducted from 06/01/ 2014 – 26/07/2015 in which all the patients that were referred to the clinical imaging department in the Women’s Hospital of Hamad Medical Corporation to rule out Invasive Placental Disease (IPD) were selected based on our following inclusion and exclusion criteria: Inclusion Criteria: All patients with US,
MRI and Intraoperative findings during this period were included. Exclusion Criteria: Patients without US,
MRI or Intraoperative findings...
Total 28 patients were assessed with their US,
MR and intraoperative findings. True Positives (TP): Patients that were positive for IPD on US or MR and came positive intraoperatively. True negative (TN): Patients that were negative for IPD on US or MR and came negative intraoperatively. False Positives (FP): Patients that were positive for IPD on US or MR and came negative intraoperatively. False Negatives (FN): Patients that were negative for IPD on US or MR and came positive...
According to our study US should remain the first-line imaging modality to diagnose IPD as it has greater sensitivity compared to MRI,
easy accessibility and cost effectivity. MRI however is a problem solving-tool to assess inconclusive or equivocal sonographic findings,
especially in patients with posterior placenta and morbidly obese patients.
MRI also has greater positive predictive value than US in positive cases of IPD.
