We examined the features of technegas, pertechnegas, and related nonradioactive aerosols using transmission electron microscopy. Samples of technegas, pertechnegas and unlabeled saline aerosols were created and collected within the Technegas Generato

We compared tomographic scintimammography performed using single photon emission computed tomography (SPECT), positron emission coincidence imaging (PECI) and positron emission tomography (PET). A female thorax phantom was used. Activities of the myo

The purpose of this study was to evaluate performance of the EM-IntraSPECT (EMIS) algorithm for non-uniform attenuation correction in the chest. EMIS is a maximum-likelihood expectation maximization (MLEM) algorithm for simultaneously estimating SPEC

99m-Tc-pertechnetate SPECT studies of thyroid phantoms, with volumes in 13-198 cc range, and of a number of patients were performed. A modified reconstruction and analytic methods were applied to the data analysis. It involved: (1) transformation of

This paper describes a new image reconstruction method to reduce the presence of image artifacts in scintimammography. SPECT data are mathematically modified prior to conventional image processing, followed by an inverse transform, which permits the

Imaging with In-111-labeled leukocytes has become an established clinical method for the detection of focal inflammatory lesions in many medical centers but has been rejected by others because of the technical complexities of the labeling procedure.

Several new derivatives of lidocaine were synthesized and used to examine the intra- and extrahepatic bile ducts and gallbladder. Diisopropyl-IDA exhibited approximately twice the bile concentration of 131I-rose bengal during the first hour after inj
