The unambiguous detection of specific neuronal subtypes is up to now only possible with invasive techniques or optical imaging after genetic modification. High field magnetic resonance imaging (MRI) has the ability to visualize the brain structure and anatomy noninvasively, with high resolution--but missing the cell specific and functional information.

PURPOSE To dissect the contributions to the longitudinal relaxivity (r1 ) of two commercial contrast agents (CAs), Gd-DOTA and Gd-HP-DO3A, and to synthesize/characterize a novel macrocyclic agent (Gd-Phen-DO3A) having superior r1 . METHODS Longitudinal relaxation rates R1 of the CAs in saline with/without human serum albumin (HSA), ionized simulated body(More)
OBJECTIVE To compare the standard methods for ultrasound measurement of fetal head circumference (HC) and biparietal diameter (BPD) (outer-to-outer (BPDoo) vs outer-to-inner (BPDoi) caliper placement), and compare acquisition of these measurements in transthalamic (TT) vs transventricular (TV) planes. METHODS This study utilized ultrasound images acquired(More)
