Current Protocols in Protein Science, 1995
AbstractIn all cases where radioisotopes are used, depending on the quantity and nature of the isotope, certain precautions must be taken to ensure the safety of the scientist. This appendix outlines a few such considerations relevant to the isotopes most frequently used in biological research.

Minimally Invasive Therapy & Allied Technologies, 2002
Intracoronary stent placement following PTCA improves the long-term outcome of the treated patient, but in-stent restenosis remains problematic, especially in smaller vessels and longer lesions. Intravascular brachytherapy is a rapidly evolving field of research and clinical treatment, with a number of different irradiation techniques being used ...

The Annals of Thoracic Surgery, 1974
In this study, radioactive venography using a gamma scintillation camera was applied experimentally in 10 dogs and clinically in 12 patients with signs of venous disorders of the superior or inferior vena caval system. The method proved to be reliable in detecting venous obstruction, displacement of the veins, or development of collaterals.

Transfusion, 2005
The transfusion of radiolabeled red cells and platelets (PLTs) allows for the accurate determination of in vivo recovery and survival after subjecting the cells to an experimental collection, processing, or storage system. The techniques utilized in these protocols have undergone refinement over the past several decades, and these improvements have ...

Radioactivity and Radioisotopes
2010Radioactivity was discovered in 1896 by Henri Becquerel, when he found that a mixture of uranium salts emitted a mysterious penetrating radiation that passed through thin sheets of metal. Since then, radioactivity has been applied in many diverse areas within the fields of industry, agriculture, medicine, and the military.

Radioisotope Photoscanning of the Liver
Gastroenterology, 1963Summary A series of 950 photoscans of the liver with I 131 Rose Bengal were reviewed. Of 548 scans in which the diagnosis could be,confirmed by autopsy, laparotomy, or biopsy, 461 patients were correctly diagnosed by scanning; 333 cases were correctly diagnosed as positive and 128 cases were correctly diagnosed as negative. Of the 69 which were false

Liver Studies with Radioisotopes
Australasian Radiology, 1976SummaryRadionuclide scanning of the liver is both sensitive and non‐traumatic and has become a widely accepted method of investigation of the hepatobiliary system. It is essential to understand the anatomical, physiological and pathological basis of liver scanning using various techniques and radiopharmaceuticals. This paper reviews the methodology and

The Universe is only about 1.3 × 1010 years old, so radionuclides which were created along with the stable nuclides and which have a half life of 108 years or more are still to be found. The radioisotopes which fall into this category are collected in Table 2.1, along with approximate values of their half-lives.

Theory of radioisotope scanning
The International Journal of Applied Radiation and Isotopes, 1958Abstract The visualization of radioisotope distributions is an increasingly important application of radioisotopes. A general relation is derived, valid for any detecting system, yielding the optimal radioisotope content as a function of resolution, detector efficiency, time duration of scan, and dimensions of the object being scanned.
