Abstmcr. The Cassini spaceaaft , launched in October 1997 to reach Saturn in 2004, carries two magnetometer xperiments on a lo-meter boo”, one at the mid-section of the boom and the other at the end of the boom. In order to gather valid scientific magnetic field data and avoid electromagnetic nterference, the spacecraft had to comply with stringent magnetostatic cleanliness requirements. Amidst...

Abstract Accelerator-produced radioisotopes are widely used in modern medicine, for imaging, cancer therapy, and combinations of therapy diagnostics (theragnostics). Clinical trials well advanced several radioisotope-based treatments that might open the way to a strong request specific accelerator systems dedicated radioisotope production. While cyclotrons standard tool this domain, we explore ...

Background: Diuretic renography using 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) is a relatively non-invasive technique and has been increasingly used as reliable for the evaluation of kidney function in wide range disorders. Methods: In this retrospective study, we retrieved medical records patients referred to Radiology Department Radiology, King Abdulaziz Specialist Hospital, Taif, Saudi Ar...

Threatens Patient Care I n what members of the nuclear medicine community referred to as a ‘‘devastating’’ and ‘‘catastrophic’’ series of events, the Canadian supplier of more than 50% of the world’s marketed radioisotopes shut down its reactor in late November. The result was an immediate shortage of 99mTc generators that forced a scramble for alternative suppliers and drastic reductions in th...

A perennial difficulty in the field of radioisotope scanning* is the fact that the requirements for resolu tion and number of counts are specified independ ently although everyone knows that both contribute to the ultimate picture quality. This difficulty results from the fact that the image degradation due to blurring and that due to statistics are not directly comparable. Blurring introduces ...
