Predictors of toxicity in treating patients with neuroblastoma by radiolabeled metaiodobenzylguanidine
(Springer-Verlag, 1994-01)
We searched for methods that would enable prescriptions of the maximum tolerable doses of iodine-131 metaiodobenzylguanidine (MIBG) and iodine-125 MIBG in the treatment of patients with neuroblastoma. We correlated doses, ...
Gastric xenon trapping mimicking COPD: Recognition using an effervescent agent
(Springer-Verlag, 1986-07)
Trapping of xenon 133 in the stomach due to gas swallowing can mimic xenon 133 retention in the left lower lobe due to obstructive lung disease on pulmonary ventilation/perfusion studies. In such cases, ingestion of sodium ...
Preliminary assessment of fluorine-18 fluorodeoxyglucose positron mission tomography in patients with bladder cancer
(Springer-Verlag, 1997-06)
The purpose of this study was to assess the feasibility of imaging of bladder cancer with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scanning. We studied 12 patients with histologically proven ...
Autoradiography-based, three-dimensional calculation of dose rate for murine, human-tumor xenografts
(Elsevier, 1993-11)
A Fast Fourier Transform method for calculating the three-dimensional dose rate distribution for murine, human-tumor xenografts is outlined. The required input includes evenly-spaced activity slices which span the tumor. ...
Uptake of positron emission tomography tracers in experimental bacterial infections: a comparative biodistribution study of radiolabeled FDG, thymidine, l -methionine, 67 Ga-citrate, and 125 I-HSA
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-04)
The purpose of this study was to evaluate the localization of positron emission tomography (PET) tracers [2-deoxy-2-fluoro- d -glucose (FDG), thymidine, and l -methionine] in sites of bacterial infection, and to contrast ...
Enterobiliary fistulae: A potential cause of a false-negative hepatobiliary study in the diagnosis of acute cholecystitis
(Springer-Verlag, 1985-02)
Cholescintigraphy has gained widespread acceptance in detection of acute cholecystitis (AC). Gallbladder (GB) visualization within 4 h effectively rules out A.C. with a high degree of specificity. We present a case of A.C. ...
Scatter modelling and compensation in emission tomography
(Springer-Verlag, 2004-05)
In nuclear medicine, clinical assessment and diagnosis are generally based on qualitative assessment of the distribution pattern of radiotracers used. In addition, emission tomography (SPECT and PET) imaging methods offer ...
Synthesis of a nonpeptide carbon-11 labeled substance P antagonist for PET studies
(Elsevier, 1993-05)
CP 96,345 is a nonpeptide high affinity antagonist of the substance P (NK1) receptor. The radiosynthesis of [11C]CP 96,345 suitable for Positron Emission Tomography (PET) applications is described. [11C]CP 96,345 was ...
Diagnostic interventions in nuclear medicine
(Elsevier, 1989)
Diagnostic interventions in nuclear medicine may be defined as the coadministration of a nonradioactive drug or application of a physical stimulus or physiologic maneuver to enhance the diagnostic utility of a nuclear ...
FDG PET imaging of paragangliomas of the neck: comparison with MIBG SPET
(Springer-Verlag, 1995-11)
Two patients with cervical paragangliomas underwent positron emission tomography (PET) with 2-[ 18 F]-fluoro-2-deoxy-D-glucose (FDG). There was marked tumor uptake and retention of FDG. Adjacent salivary gland accumulation ...
