Final answer:
Tc DPTA is used in various medical imaging techniques, but it is not used for brain flow study. Option c.
Step-by-step explanation:
The radiopharmaceutical Tc DPTA can be used for all of the following applications, EXCEPT for brain flow study. Tc DPTA, or technetium diethylenetriaminepentaacetic acid, is commonly used as a tracer in various medical imaging techniques. It is used for aerosol lung scanning, renal flow study, shunt patency assessment, and spleen scanning.
The utilization of Tc DPTA includes aerosol lung scanning, renal flow studies, brain flow studies, shunt patency evaluation, and spleen scanning. However, PET scans, which utilize different radiopharmaceuticals, are more often employed to illustrate physiological activity such as nutrient metabolism and blood flow in targeted organs, including the brain and heart, and for the diagnosis of conditions like cancer and Alzheimer's disease.
