The effect of specimen processing on radiolabeled monoclonal antibody biodistribution
(Springer-Verlag, 1984-08)
Monoclonal antibodies are assuming increasing importance in experimental and clinical medicine. Generally, tissue biodistribution studies in animals precede human studies. To investigate a concern of ours that varying ...
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 ...
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 ...
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 ...
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 ...
High yield synthesis of high specific activity R-(-)-[11C]epinephrine for routine PET studies in humans
(Elsevier, 1993-11)
R-(-)-[11C]Epinephrine ([11C]EPI) has been synthesized from R-(-)-norepinephrine by direct methylation with [11C]methyl iodide or [11C]methyl triflate. The total synthesis time including HPLC purification was 35-40 min. ...
The appended curve technique for deconvolutional analysis —method and validation
(Springer-Verlag, 1988-09)
Deconvolutional analysis (DCA) is useful in correction of organ time activity curves (response function) for variations in blood activity (input function). Despite enthusiastic reports of applications of DCA in renal and ...
Scintigraphic detection of sinusitis
(Springer-Verlag, 1988-11)
Radionuclide scintigraphy is useful in the diagnosis of sinusitis. Three cases are described, using different radionuclide agents ( 99m Tc-MDP, 67 Ga-citrate and 111 Inleukocytes) in which sinusitis was discovered, though ...
