Concept explainers
(a)
Interpretation:
The quantity remaining in 160 mg of technetium-99m after 6 hours of usage during diagnostic procedure should be determined.
Concept Introduction:
Technetium-99m is used for diagnosing imaging procedures especially for myocardial perfusion which tells if the blood flow through the heart is good. It is considered as radioactive tracer.
(b)
Interpretation:
The quantity remaining in 160 mg of technetium-99m after 18 hours of usage during diagnostic procedure should be determined.
Concept Introduction:
Technetium-99m is used for many diagnosing imaging procedures. It is mainly used to indicate how well the blood flows in the heart which is myocardial perfusion. This element is considered as radioactive tracer.
(c)
Interpretation:
The quantity remaining in 160 mg of technetium-99m after 24 hours of usage during diagnostic procedure should be determined.
Concept Introduction:
Technetium-99m is used for many diagnosing imaging procedures. It is mainly used to indicate how well the blood flows in the heart which is myocardial perfusion. This element is considered as radioactive tracer.
(d)
Interpretation:
The quantity remaining in 160 mg of technetium-99m after 2 days of usage during diagnostic procedure should be determined.
Concept Introduction:
Technetium-99m is used for many diagnosing imaging procedures. It is mainly used to indicate how well the blood flows in the heart which is myocardial perfusion. This element is considered as radioactive tracer.
