The ability to track cells and their patterns of gene expression in living organisms can increase our understanding of tissue development and disease. Gene reporters for bioluminescence, fluorescence, radionuclide, and magnetic resonance imaging (MRI) have been described but these suffer variously from limited depth penetration, spatial resolution, and sensitivity. We describe here a gene repor...

A scanning collimated line source for simultaneously acquiring emission and transmission data from a gamma camera has been developed. The line source is microprocessor-controlled and incorporates hardware to electronically window the spatial gamma camera signals in order to separate the emission signals of the subject from transmission signals from the line source. The device improves upon the ...

Gallium-68 a positron emitter radionuclide, with great impact on the nuclear medicine, has been widely used in positron emission tomography (PET) diagnosis of various malignancies in humans during more recent years especially in neuroendocrine tumors (NETs). The vast number of 68Ge/68Ga related generator productions, targeting molecule design (proteins, antibody fragments,...

The relation between perfusion defects shown by radionuclide angiography and static brain scan positivity was evaluated in patients with ischaemic completed stroke at various intervals from the onset of symptoms. An inverse relation between radionuclide angiography and static scan positivity was found for the period within 15 days of the onset of symptoms. The possible relation between changes ...

This paper represents a review of the recent literature on techniques to measure myocardial blood flow in man. A short discussion on flow meters in followed by a more detailed discussion of the radionuclide techniques used to measure myocardial blood flow. The radionuclide techniques are discussed in two groups: (1) qualitative measurement of blood flow using static images; and (2) quantitative...

Although our understanding of microorganisms has advanced significantly and antimicrobial therapy has become increasingly available, infection remains a major cause of patient morbidity and mortality. The role of radionuclide imaging in the evaluation of the patient suspected of harboring an infection varies with the situation. For example, in the postoperative patient, radionuclide imaging is ...

We determined the sequence and timing of inward ventricular wall motion by least-square phase analysis of radionuclide cineangiograms in 10 patients with left bundle branch block (LBBB), five patients with right bundle branch block (RBBB) and 11 patients with normal conduction. All LBBB and RBBB patients had normal coronary arteries and no segmental wall motion abnormalities. The left ventricle...

Disorders of the upper digestive tract have a high impact on modern society, in terms of both direct and indirect health care costs and of social burden. The most common presenting symptom is either dysphagia or dyspepsia. Discriminating specific diagnoses within this wide group of diseases requires sound clinical judgment and application of procedures to distinguish organic from nonorganic dis...

radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in csf (cerebro-spinal-fluid) flow. we present a case of complicated csf shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. the findings were confirmed by surgery performed for correction of the shunt ...
