Detection of liver fibrosis with magnetic cross-relaxation
(Wiley Subscription Services, Inc., A Wiley Company, 1994-05)
The utility of MRI using magnetization transfer (MT) enhanced pulse sequences to diagnose hepatic cirrhosis in a rat model was investigated. Hepatic T 1 was measured with and without MT off-resonance RF pulses in 17 ...
PET and P300 relationships in early Alzheimer's disease
(Elsevier, 1990)
The P300 (P3) wave of the auditory brain event-related potential was investigated in patients with probable Alzheimer's disease to determine whether P300 latency discriminated these patients from controls and whether ...
Chronic electrical stimulation reverses deafness-related depression of electrically evoked 2-deoxyglucose activity in the guinea pig inferior colliculus
(Elsevier, 1993-11)
The [14C]-2-deoxyglucose (2-DG) autoradiographic technique was used to study how auditory-related metabolic activity changes with deafness, and how chronic electrical stimulation of the deafened system may modify these ...
A simple technique for eliminating tracheal buckling on lateral neck roentgenograms
(Springer-Verlag, 1974-03)
Brief, gentle extrinsic pressure on the trachea at the level of the cricothyroid membrane during lateral roentgenography of the neck is suggested as a safe, simple, and reliable means of evaluating the retrotracheal ...
Applications of magnetic resonance imaging and magnetic resonance angiography to evaluate the hepatic vasculature in the pediatric patient
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-03)
Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) offer several techniques to evaluate the hepatic vasculature. These techniques are briefly reviewed with reference to the pediatric population. ...
An academic health center cost analysis of screening mammography
(Wiley Subscription Services, Inc., A Wiley Company, 2004-09-01)
BACKGROUND The current study sought to determine the institutional financial impact of a screening mammography (SM) program in the context of an integrated cancer center. METHODS Using administrative databases, 10,048 ...
Spectrum of pheochromocytoma in the 131 I-MIBG era
(Springer-Verlag; Société Internationale de Chirurgie, 1988-08)
131 I-metaiodobenzylguanidine ( 131 I-MIBG) scintigraphy allows for both functional diagnosis and anatomical localization of pheochromocytoma. The spectrum of pheochromocytoma since the routine use of preoperative 131 ...
A progressive gradient moment nulling design technique
(Wiley Subscription Services, Inc., A Wiley Company, 1991-05)
A method is presented for designing motion-compensated gradients in a progressive manner. The method is easily applicable to many types of waveforms, and can compensate for any order of motion. It can be implemented ...
Continuous arterial spin labeling using a train of adiabatic inversion pulses A portion of this work was presented at the 10th Annual Meeting of ISMRM, Honolulu, 2002.
(Wiley Subscription Services, Inc., A Wiley Company, 2005-03)
Purpose To develop a simple and robust magnetic resonance imaging (MRI) pulse sequence for the quantitative measurement of blood flow in the brain and cerebral tumors that has practical implementation advantages over ...
