Histological Characterization of Microlesions Induced by Myocardial Contrast Echocardiography
(Blackwell Science Inc, 2005-01)
Congenital short-gut syndrome
(Springer-Verlag, 2004-05)
A case of congenital short gut is reported in a 4-month-old boy presenting with failure to thrive. Upper gastrointestinal examination (UGI) with small bowel follow-through (SBFT) demonstrated dilation of the duodenum and ...
Transient small-bowel intussusception in children on CT
(Springer-Verlag, 2003-05)
Objective. To determine the frequency and significance of small-bowel intussusception identified in children on CT.
Sonographic appearance of extensive hepetic arterial calcification mimicking pneumobilia
(John Wiley & Sons, Inc., 2002-01)
Pneumobilia appears sonographically as intrahepatic linear echogenic regions that often produce distal acoustic shadowing. We present a case in which extensive hepatic arterial calcification mimicked the sonographic ...
Design of a very high-resolution small animal PET scanner using a silicon scatter detector insert
(IOP Publishing Ltd, 2007-08-07)
A small animal positron emission tomography (PET) instrument using a high-resolution solid-state detector insert in a conventional PET system was investigated for its potential to achieve sub-millimeter spatial resolution ...
Magnetic field perturbation of neural recording and stimulating microelectrodes
(IOP Publishing Ltd, 2007-04-21)
To improve the overall temporal and spatial resolution of brain mapping techniques, in animal models, some attempts have been reported to join electrophysiological methods with functional magnetic resonance imaging (fMRI). ...
Three-dimensional static displacement, stimulated echo NMR elasticity imaging
(IOP Publishing Ltd, 2000-06-01)
This article presents a method for measuring three-dimensional mechanical displacement and strain fields using stimulated echo MRI. Additional gradient pulses encode internal displacements in response to an externally ...
Advanced three-dimensional tailored RF pulse for signal recovery in T 2 *-weighted functional magnetic resonance imaging
(Wiley Subscription Services, Inc., A Wiley Company, 2006-11)
T 2 * -weighted functional MR images are plagued by signal loss artifacts caused by susceptibility-induced through-plane dephasing. We present major advances to the original three-dimensional tailored RF (3DTRF) pulse ...
MRI and 2D-CSI MR spectroscopy of the brain in the evaluation of patients with acute onset of neuropsychiatric systemic lupus erythematosus
(Springer-Verlag, 2005-08)
MRI and 2D-CSI spectroscopy were performed in eight patients with systemic lupus erythematosus who presented with acute onset of neuropsychiatric lupus (NP-SLE), and in seven normal controls to evaluate for differences in ...
