Increased genital uptake of 99m Tc red blood cells: A potential cause of false-positive studies for gastrointestinal bleeding
(Springer-Verlag, 1984-05)
We have recently seen several 99m Tc labeled red blood (Tc-RBC) cell studies, for the localization of gastrointestinal (GI) bleeding, which were difficult to interpret because of increased activity in the low abdomen, which ...
Vibrational analysis of peptides, polypeptides and proteins. XII—fermi resonance analysis of the unperturbed ND stretching fundamental in polypeptides
(John Wiley & Sons, Ltd., 1982-04)
We have obtained the spectrum of β‐poly(L‐alanine‐ND), and find three bands in the ND stretching region. By comparison with Fermi resonance analyses of deuterated derivatives of polyglycine I as well as with α‐poly(L‐alanine‐ND), ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Phaeochromocytoma and functioning paraganglioma in childhood and adolescence: role of iodine 131 metaiodobenzylguanidine
(Springer-Verlag, 1991-03)
Phaeochromocytomas and functioning paragangliomas are rare tumours in childhood and adolescence. We review our experience of 43 cases (24 men, 19 women) who were first diagnosed at the age of ⩽ 18 years. All patients were ...
Inverse Raman spectroscopy of bilirubin and its ditauride
(John Wiley & Sons, Ltd., 1984-08)
The inverse Raman spectrum of bilirubin and bilirubin ditauride were measured under pre‐resonant conditions. Spectra in chloroform and dimethyl sulfoxide were assigned by comparison with model compounds and on the basis ...
The (F)utility of the thallium-201 quantitative lung/myocardial ratio in the detection of coronary artery disease
(Springer-Verlag, 1986-01)
Exercise-induced increases in pulmonary uptake of thallium-201 ( 201 Tl) have been associated with exercise-induced myocardial dysfunction. To evaluate this phenomenon more replicably, a quantitative semi-automated computer ...
Electric Dipole Moments of Rare Gas-Carbonyl Sulfide van der Waals Complexes
(Elsevier, 1993-08)
The [mu]a and [mu]b electric dipole moment components of the Ne-OCS, Ar-OCS, and Kr-OCS van der Waals complexes were determined using Fourier transform microwave spectroscopy. The accuracy of these results was evaluated ...
A simple method for production of slides of CT images from multiformat radiographs
(Elsevier, 1978)
Sixteen on 1 multiformat images of CT scans can be mounted directly into special "super slide" 2 by 2 in. mounts. Use of special photographic equipment is thus avoided.
Gated cardiac blood pool studies in atrial fibrillation: role of cycle length windowing
(Springer-Verlag, 1991-01)
Cycle length windowing is gaining increasing acceptance in gated blood pool imaging of patients with atrial fibrillation (AF). The goals of this study were: to assess differences of ejection fraction (EF) in AF with and ...
Computed tomography of malignant tumors of the osseous pelvis
(Elsevier, 1983)
The medical records, conventional radiographs, bone scans and pelvic CT scans obtained in 50 consecutive patients with malignant lesions involving the osseous pelvis were retrospestively reviewed. In 21 patients with primary ...
