Regional 2-[ 18 F]fluoro-2-deoxy- d -glucose uptake varies in normal lung
(Springer-Verlag, 1996-05)
2-[ 18 F]fluoro-2-deoxy- d -glucose positron emission tomography (FDG-PET) is a promising imaging procedure for detecting primary and metastatic cancer in the lungs. We have, however, failed to detect some small tumors in ...
Computation of electric dipole matrix elements for hydrogen fluoride
(Elsevier, 1973-02)
The electric dipole matrix elements of hydrogen fluoride have been calculated by numerical integration for transitions involving large quantum numbers [upsi], J. Overtones have been included through [Delta][upsi] = 5 . ...
Total radiances and equivalent widths of isolated lines with combined Doppler and collision broadened profiles
(Elsevier, 1968-08)
Analytical expressions for total radiances and equivalent widths of isolated spectral lines with combined Doppler and collision broadened profiles are presented for isothermal paths.
Characterization of the flavin–protein interaction in L ‐Lactate oxidase and old yellow enzyme by resonance inverse Raman spectroscopy
(John Wiley & Sons, Ltd., 1987-06)
Resonance inverse Raman spectroscopy was used to examine the interactions between the flavin and surounding protein in L ‐lactate oxidase (from Mycobacterium smegmatis ) and Old Yellow Enzyme (from brewer's bottom yeast). ...
CT evaluation of mediastinal masses
(Elsevier, 1987)
CT is an important modality for imaging mediastinal masses, and certain CT attenuation features (fat, calcium, or water attenuation, contrast enhancement) are well known to suggest specific diagnoses. In a series of 132 ...
Rotational analysis of the red electronic emission system A3[Phi] --> X3[Delta] of diatomic niobium nitride (NbN)
(Elsevier, 1988-08)
The (0,0) band of the red emission system of the diatomic molecule niobium nitride (NbN) has been rotationally analyzed and found to arise from an A3[Phi]r-X3[Delta]r transition. Constants for the two states have been ...
Monte Carlo evaluation of object shape effects in iodine-131 SPET tumor activity quantification
(Springer-Verlag, 2001-07)
In our clinical iodine-131 single-photon emission tomography (SPET) quantification for radioimmunotherapy, calibration and partial volume correction are based on measurements with phantoms containing spheres to simulate ...
Scintigraphy of incidentally discovered bilateral adrenal masses
(Springer-Verlag, 1995-04)
The purpose of this study was to determine the patterns of iodine-131 6β-iodomethylnorcholesterol (NP-59) imaging and the correlation with computed tomography (CT)-guided adrenal biopsy and follow-up in patients with ...
Some measurements of the infrared spectral radiances and emissivities of hydrogen fluoride in combustion gases at 1000[deg]C
(Elsevier, 1964)
Spectral radiances and emissivities were determined from moderate-resolution emission and absorption measurements in the exhaust gases of a small rocket motor. Data was obtained in the 2 to 3 [mu] region for ClF3-NH3 ...
CT evaluation of the equivocal pulmonary nodule
(Elsevier, 1987)
In the setting of a questionable pulmonary nodule demonstrated by conventional radiographs, the place of CT in the diagnostic algorithm is not well established. We reviewed our experience in 50 consecutive patients referred ...
