Abstract
A method of radioimaging a myocardial perfusion, the method including in sequence: administering to a subject a low dose of a first radiopharmaceutical; subjecting the subject to a physical stress; administering to the subject at a peak of said physical stress a medium or high dose of a second radiopharmaceutical; and immediately radioimaging using a 3D non-coincidence imaging method a heart of the subject, thereby radioimaging a myocardial perfusion.
Claims10
A method of radioimaging a myocardial perfusion while avoiding at least some liver radioactivity, the method comprising in sequence the steps of:
- (a) administering to a subject a first dose of a first radiopharmaceutical;
- (b) subjecting said subject to a physical stress;
- (c) administering to said subject at a peak of said physical stress a second dose of a second radiopharmaceutical, said second dose being higher than said first dose;
- and
- (d) immediately, within a time interval of less than 3 minutes from said administering in step (c), radioimaging a heart of said subject with a radioimaging camera using a 3D non-coincidence imaging method, wherein said first radiopharmaceutical comprises an isotope including Tl-201 or Tc-99m and said second radiopharmaceutical comprises an isotope including Tc-99m or Iodine-123, thereby radioimaging a myocardial perfusion.
