A 29-year-old woman presenting with an ectopic adrenocorticotropic hormone syndrome and a nodule of the upper lobe of the left lung was explored by indium 111 (111In) octreotide scintigraphy. This showed a pathologic uptake by the nodule. Treatment with octreotide resulted in the rapid control of hypercortisolism prior to surgery.
A 50-year-old woman is described with a very unusual combination of MEN-1 syndrome with a negative family history. At first she had been treated because of a clinically non-functioning pituitary adenoma in the maxillary sinus. Six years later a carcinoid tumour was discovered by means of 111In-pentreotide scintigraphy.
Opportunistic infections are common in patients after renal transplantation. This report describes a case of cytomegalovirus pneumonia in a renal transplant recipient with a normal chest roentgenogram and normal arterial oxygenation. An abnormal 111In-white blood cell scan led to the discovery of a pulmonary source of his recurrent fevers.
We have previously developed a fast Monte Carlo (MC)-based joint ordered-subset expectation maximization (JOSEM) iterative reconstruction algorithm, MC-JOSEM. A phantom study was performed to compare quantitative imaging performance of MC-JOSEM with that of a triple-energy-window approach (TEW) in which estimated scatter was also included additively within JOSEM, TEW-JOSEM. We acquired high-cou...
Somatostatin (SS) and SS receptor (SSR) subtypes, code-named sst1-5, are heterogeneously expressed in the normal human thymus. This suggests their involvement in controlling the immune and/or neuroendocrine functions in this organ. Moreover, recently a high in vivo uptake of [111In-DTPA-D-Phe1]octreotide has been reported in patients bearing thymoma. The present study characterizes in vivo and ...
UNLABELLED BrE-3 is a murine IgG1 monoclonal antibody that binds to 97% of human ductal breast cancer specimens. A previous study documented the ability of 111In-labeled 1,4-methyl-benzyl isothiocyanate diethylenetriamine pentaacetic acid (111In-MX-DTPA) BrE-3 to specifically target breast cancer tissue in patients, and the dosimetry derived from the pharmacokinetics suggested that a useful the...
PURPOSE The applicability of radioimmunotherapy with organism-specific monoclonal antibodies to treatment of infectious disease in experimental models has been recently shown for fungal, bacterial, and viral infections. To identify the best delivery vehicle for radioimmunotherapy of human pathogenic fungus Cryptococcus neoformans (CN), we have done comparative evaluation of capsular polysacchar...
UNLABELLED We have developed an efficient pretargeting strategy for renal cell carcinoma (RCC) based on a biologically produced bispecific monoclonal antibody (bs-mAb). Tumor targeting with this 2-step pretargeting strategy in the NU-12 mouse RCC model was very efficient compared with other pretargeting strategies, possibly due to unique characteristics of the NU-12 tumor used in our studies. H...
BACKGROUND In single photon emission computed tomography [SPECT], high specific activity of 111In-labelled tracers will allow administration of low amounts of tracer to prevent receptor saturation and/or side effects. To increase the specific activity, we studied the effect of the buffer used during the labelling procedure: NaAc, NH4Ac, HEPES and MES buffer. The effect of the ageing of the 111I...
