Normal levels of B-type natriuretic peptide (BNP) are not well established in pregnancy. We obtained longitudinal BNP 29 healthy pregnant women each trimester and postpartum period, compared these to the 25 nonpregnant controls. There were no significant differences among cases controls with respect weight, diastolic blood pressure, ethnicity. A total 116 values during The median (and range) level pregnancy was 19 (10-143) pg/ml versus 10 (10-37) (p = 0.003). However, there statistically at...

Abstract Purpose To investigate whether longitudinal magnetic resonance proton spectroscopic imaging (MRSI) demonstrates regional metabolite abnormalities after traumatic brain injury (TBI) that predict long‐term neurologic outcome. Materials and Methods Two‐dimensional‐MRSI (point resolved spectroscopy sequence [PRESS]; TR/TE = 3000/144 msec; 10 mm) was acquired prospectively in 42 adults with severe TBI through the level of corpus callosum 7 ± 4 days injury. Measurements were repeated 31...
