The “water-ida”: A simple means to separate duodenal from gallbladder activity on cholescintigraphic studies
(Springer-Verlag, 1984-07)
In some 99m Tc-iminodiacetic acid studies, separation of the gallbladder from the duodenum can be difficult, despite multiple views. When faced with this problem, we have had the patient ingest 250 cc of tap water. This ...
Successful and unsuccessful approaches to imaging carcinoids: Comparison of a radiolabelled tryptophan hydroxylase inhibitor with a tracer of biogenic amine uptake and storage, and a somatostatin analogue
(Springer-Verlag, 1996-02)
A mouse mastocytoma model was used to determine the biodistribution and tumour uptake of four radiopharmaceuticals developed to target the serotonin synthetic pathway in carcinoid tumours. Three of the compounds were ...
Resonance enhanced multiphoton ionization of nucleosides by using pulsed-laser desorption in supersonic beam mass spectrometry
(Elsevier, 1989-04-01)
Pulsed-laser desorption is used as a means of volatilizing nucleosides into the gas phase for entrainment into a supersonic jet expansion. These species are then studied in a time-of-flight mass spectrometer by resonance ...
The electronic absorption spectrum of crystallinechromyl chloride at 1.7[deg]K
(Elsevier, 1968-01)
The spectrum of chromyl chloride, CrO2Cl2 , in the region 6000 A-3800 A hasbeen obtained for the crystalline substance at temperatures down to 1.7[deg]K. Three absorption systems have been observed, together with the start ...
Interpretation of the vibrational behavior of methyl and substituted methyl radicals perturbed by alkali halide molecules
(Elsevier, 1970-12)
The observed vibrational behavior of free and alkali halide-perturbed methyl radicals in low temperature inert matrices is rationalized on the basis of the relaxation of the molecular charge distribution of the methyl ...
The emission and absorption spectra of chromyl chloride in an argon matrix at 4 K
(Elsevier, 1974-07)
The emission and absorption spectra of chromyl chloride (and the pure 35Cl isotopic species) have been obtained in an argon matrix at 4 K. In emission, two systems are obtained and these correlate with the two systems ...
Rotation spectrum of methyl alcohol
(Elsevier, 1959)
The rotation spectrum of methanol vapor has been measured from 50 to 457 cm-1. Combining these data with the work of Borden and Barker provides an accurate map of the spectrum to 625 cm-1 together with some provisional ...
Polarized Raman spectra of oriented films of Α-helical poly( L -alanine) and its N -deuterated analogue
(John Wiley & Sons, Ltd., 1998-01)
Polarized Raman spectra were obtained on well oriented films of Α-helical poly( L -alanine) (Α-PLA) and its N -deuterated analogue in order to obtain definitive assignments of the E 2 -species modes. Such assignments ...
Femoral and obturator neuropathy secondary to retroperitoneal hemorrhage the value of the ct scan
(Elsevier, 1981)
A man developed signs of femoral and obturator neuropathy due to spontaneous retroperitoneal hemorrhage while taking anticoagulant drugs for suspected thrombophlebitis. The hemorrhage was demonstrated by CT scan. CT scans ...
Tomographic renal cortical scintigraphy: Correlation with intravenous urography, computed tomography, ultrasonography, angiography, and nuclear magnetic resonance imaging
(Springer-Verlag, 1985-11)
This study evaluates single-photon renal tomoscintigraphy (SPECT) in the evaluation of renal masses and correlates this modality, where indicated, with computed tomography (CT), ultrasonography (US), angiography (ANGIO) ...
