MRI can be a reliable and reproducible tool for the detection of suspected placental invasion, but the diagnostic value significantly depends on observers' experience.Ĭopyright © 2012 Elsevier Ireland Ltd. Seniors detected placental invasion and depth of infiltration with significantly higher diagnostic certitude than juniors (p=0.0002 and p=0.0282, respectively). Interobserver agreement for detecting placental invasion was 0.64 for seniors and 0.41 for juniors, thus substantial and moderate, respectively. radiographs of infants with suspected necrotizing enterocolitis (NEC). The best single MR-feature indicating placental invasion was T2-hypointense placental bands (r(2)=0.28), followed by focally interrupted myometrial border, infiltration of pelvic organs and tenting of the bladder (r(2)=0.36). We examined (1) the observer variability (both interobserver and intraobserver). Overall sensitivity and specificity for placental invasion was 90.9% and 75.0% for seniors and 81.8% and 61.8% for juniors, respectively. Stepwise logistic regression was performed including the 6 MR-features predictive of placental invasion.ĭemographics between both groups were statistically equivalent. Interobserver agreements between senior and junior readers were determined.

For each reader the sensibility, specificity, and receiver operating curve (ROC) were calculated. Two senior and two junior radiologists blindly and independently reviewed MR-examinations in view of 6 previously defined MR-features indicating presence and degree of placental invasion (placenta increta, accreta or percreta). contrast), among them 12 with histopathologically proven placental invasion and 13 women (52%) without placental invasion used as control group.

Our population included 25 pregnant women (mean age 35.16) investigated by prenatal MRI (1.5T, T1- and T2-weighted MR-sequences without i.v. Seeing this for the first time is a major advance in understanding how our sun continuously generates the vast amount of energy needed to heat its atmosphere.To evaluate the diagnostic value of previously described MR features used for detecting suspected placental invasion according to observers' experience. Jederico is talking about the assassin who chased Dawn Priestsand says that he feels as though he was a target recently.I want to find out who is trying to. Because of the level of solar activity, we were able to clearly focus on an active sunspot, and obtain some remarkable images. Scientists have tried for decades to understand how the sun's dynamic atmosphere is heated to millions of degrees. Hi-C principal investigator, Jonathan Cirtain, a heliophysicist at NASA's Marshall Space Flight Center, says: (Emphasis added.) The rule appears to contemplate repeated SAR filings for the same activity, but use of continuing reports rather than new reports for activity that. These images showed the evolution of the magnetic field, as well as the releases of energy at temperatures of between a mind-boggling two million and four million degrees. The SAR instructions state: A continuing report should be filed on suspicious activity that continues after an initial FinCEN SAR is filed. The telescope's 10-minute flight had it take 165 images of a large, active region of the Sun's corona.

The telecope launched from the White Sands Missile Range in New Mexico back in July of last year, and has already put smiles on scientists' faces. The new findings come courtesy of NASA's suborbital telescope, the High Resolution Coronal Imager, which has captured the highest ever resolution images of the solar corona to date, sporting five times the amount of detail than previous tools used to study our closest star.
