The role of echocardiography and CT in the diagnosis of cardiac tumors
(Kluwer Academic Publishers; Martinus Nijhoff Publishers ; Springer Science+Business Media, 1988-03)
A young male who presented with atypical chest pain was found to have a primary cardiac tumor. Chest X-ray, electrocardiogram, and echocardiographic findings can be nonspecific. Differential diagnosis and the role of ...
Fatal atlanto-axial luxation in rheumatoid arthritis
(John Wiley & Sons, Inc., 1963-06)
Fatal atlanto-axial dislocation occurred in two patients with rheumatoid arthritis and in both there were severe degenerative changes in the spinal ligaments and skeletal muscle in this area. Attention is called to the ...
Quantitative in vivo receptor binding IV: Detection of muscarinic receptor down-regulation by equilibrium and by tracer kinetic methods
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-09)
Newly-developed methods for estimation of in vivo binding to neurotransmitter receptors should enable the detection and quantification of physiologic or pathologic changes in receptor numbers. In the present study, both ...
In vivo studies of acetylcholinesterase activity using a labeled substrate, N -[ 11 C]methylpiperdin-4-yl propionate ([ 11 C]PMP)
(John Wiley & Sons, Inc., 1996-02)
Two esters, N -[ 11 C]methylpiperidyl acetate ([ 11 C]AMP) and N -[ 11 C]methylpiperidyl propionate ([ 11 C]PMP), were synthesized in no-carrier-added forms and evaluated as in vivo substrates for brain acetylcholinesterase ...
Musculoskeletal computed radiography in children: scatter reduction and improvement in bony trabecular sharpness using air gap placement of the imaging plate
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-02)
The effect of various air gaps on computed radiographic musculoskeletal images was investigated using a knee phantom. Scatter to primary radiation ratios were measured using the beam stop method at air gaps ranging from 0 ...
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 ...
Periosteal bone apposition in chondroblastoma
(Springer-Verlag; International Skeletal Society, 1979-04)
Periosteal bone apposition in chondroblastoma of long bones is more frequent than generally recognized. This should not cause confusion in differential diagnosis. The finding does not seem to have prognostic significance.
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 ...
