CT of unusual mediastinal vascular abnormalities
(Elsevier, 1984)
The previously unreported CT findings of supracardiac anomalous pulmonary venous return and Takayasu arteritis are presented. CT demonstration of a left vertical vein and an enlarged superior vena cava strongly suggests a ...
ω- 123 I-Hexadecanoic acid metabolic probe of cardiomypathy
(Springer-Verlag, 1985-03)
The utility of ω- 123 I-hexadecanoic acid myocardial scintigraphy as a metabolic probe of cardiomyopathies was investigated. Sixteen patients with a variety of cardiomyopathies and myopathies that involve cardiac muscle ...
Importance of intra-therapy single-photon emission tomographic imaging in calculating tumour dosimetry for a lymphoma patient
(Springer-Verlag, 1991-06)
The dosimetry for two, similarly sized tumours in a lymphoma patient being treated with non-bone marrow ablative, monoclonal antibody therapy is reported. The 45-year-old man was infused with 2.48 GBq (67 mCi) of 131 ...
Extraction of [18F]fluoride from [18O]water by a fast fibrous anion exchange resin
(Elsevier, 1990)
[18F]Fluoride for nucleophilic radiofluorination was recovered from target water by trapping on a fibrous anion exchange resin in the hydroxide form and subsequent displacement into wet methanolic K2CO3. Extraction into ...
Potential tumor or organ imaging agents--31. Radioiodinated sterol benzoates and carbamates
(Elsevier, 1989)
A series of radioiodinated benzoate and carbamate esters of cholesterol and pregnenolone wherein the acyl moiety served as the carrier for radioiodine was synthesized and evaluated as potential imaging agents for the adrenal ...
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, ...
Computer-aided classification of mammographic masses and normal tissue: linear discriminant analysis in texture feature space
(IOP Publishing Ltd, 1995-05-01)
The authors studied the effectiveness of using texture features derived from spatial grey level dependence (SGLD) matrices for classification of masses and normal breast tissue on mammograms. One hundred and sixty-eight ...
Clinically feasible reconstruction of 3D whole-body PET/CT data using blurred anatomical labels
(IOP Publishing Ltd, 2002-01-01)
We present the results of utilizing aligned anatomical information from CT images to locally adjust image smoothness during the reconstruction of three-dimensional (3D) whole-body positron emission tomography (PET) data. ...
Synthesis of fluorine-18 labeled GABA uptake inhibitors
(Elsevier, 1990)
The first syntheses of fluorine-18 labeled inhibitors of GABA reuptake [(R,S)-1-{2-{4-[18F]fluorophenyl}phenyl}methoxyethyl]piperidine-3-carboxylic acid, (R,S)-1-{2-(4-[18F]fluorophenyl)(4-fluorophenyl)methoxyethyl}piper ...
A constrained dual-energy reconstruction method for material-selective transmission tomography
(Elsevier, 1994-12-30)
A new reconstruction method has been developed for material-selective tomography that allows non-negativity and maximum density constraints to be enforced on each pixel. In addition, uncertainty in the projection data is ...
