7 cubic mm of a volume of at least 5 cm diameter, comprising;
administering a radiopharmaceutical to a patient;
acquiring radiation emission data from an organ of said patient for a period of 5 minutes or less using a SPECT camera, wherein said acquiring comprises blocking radiation from a field of view of said camera using one or more radiation attenuation elements; and
reconstructing, from said data, a clinically-valuable image of a volume of about at least 5 cm diameter including at least a part of said organ at a resolution of at least 7×

Abstract
Protocols for radioimaging an event or disorder are provided. An exemplary protocol comprises a method of radioimaging a myocardial perfusion, the method comprising in sequence:
- (a) administering to a subject about 3 mCi Tl201 thallous chloride;
- (b) allowing said subject to rest;
- (c) radioimaging a heart of said subject;
- (d) subjecting said subject to a physical stress;
- (e) administering to said subject at a peak of said physical stress about 20-30 mCi Tc99m sestamibi; and
- (f) radioimaging said heart of said subject, thereby radioimaging a myocardial perfusion.

40. A method of radioimaging a heart, to obtain a clinically-valuable image having a resolution of at least 7×
- 7×
7 mm of a volume of at least 5 cm diameter, comprising;administering a radiopharmaceutical to a patient at a low dose having an EDE (effective dose equivalent) of less than 2.5 millirem per Kg weight of said patient; acquiring radiation emission data from a heart of said patient using a collimated SPECT camera, said radiation being emitted by said low dose radiopharmaceutical, wherein said acquiring comprises acquiring radiation emission data from said heart for a period of 5 minutes or less using a SPECT camera, wherein said acquiring comprises blocking radiation from a field of view of said camera using one or more radiation attenuation elements; and reconstructing, from said data, a clinically-valuable image of a volume of about at least 5 cm diameter including at least a part of said heart at a resolution of at least 7×
