Another look at ultrasound and magnetic resonance imaging for diagnosis of placenta accreta.

Objective: To compare the ability of magnetic resonance imaging (MRI) and ultrasound (US) in the diagnosis of placenta accreta, to examine the success of various sonographic and MRI features to correctly predict invasive placenta, and to define a specific role for MRI in placenta accreta.

Methods: After Institutional Review Board approval, a blinded retrospective review was undertaken of US and MRI findings from 45 patients who had an obstetrical US and placental MRI between August 2006 and January 2012. Correlation with clinical history and pathologic findings was performed.

Interstitial twin pregnancy: A unique case presentation.

Early recognition and timely treatment of an interstitial pregnancy is imperative to avoid the high morbidity and mortality of this type of ectopic pregnancy. We report a case of twin interstitial pregnancy that was initially missed on initial sonogram and was subsequently recognized at our institution by transvaginal sonography. The patient underwent open laparoscopic surgery with cornual wedge resection but suffered infundibulopelvic ligament hemorrhage and subsequently required ipsilateral salpingo-oophorectomy.

How much free fluid can a pregnant patient have? Assessment of pelvic free fluid in pregnant patients without antecedent trauma.

Background: The amount of free fluid that can normally be present in a pregnant patient is unknown. Evaluation of pelvic free fluid in a population of pregnant patients without early history of trauma would help determine what amount of free fluid should raise suspicion of intra-abdominal injury in those who have suffered trauma.

Methods: Patients presenting for routine obstetric ultrasound without an early history of trauma were offered participation in the study.

Fetal radiation dose during gestation estimated on an anthropomorphic phantom for three generations of CT scanners.

Objective: The purpose of this study is to determine fetal dose during four different stages of pregnancy for both pulmonary CT angiogram and abdominal and pelvic CT examination on 4-, 16-, and 64-MDCT scanners measured in an anthropomorphic phantom simulating a pregnant patient.

Materials And Methods: Pulmonary angiograms and abdominal and pelvic studies were performed on a phantom on 4-, 16-, and 64-MDCT scanners. Fetal positioning and mean fetal depth were determined using data from ultrasound examinations of a large cohort of patients.
