Answer: Radioactively-labeled materials

Explanation: nuclear medicine is a medical specialty that uses radioactive tracers to diagnose and treat different diseases. Radioactive tracers are materials that can vary according to the purpose of the method. For most diagnostic, the radioactive tracer is administered by intravenous injection. However it may also be administered by inhalation, by oral ingestion, or by direct injection into an organ.

SPECT scans are primarily used to diagnose and track the progression of heart disease, and the major purpose of PET scans is to detect cancer and monitor its progression, response to treatment, and to detect metastases. This two methods are the most used in nuclear medicine.

Which quotation reflects the perspective of most Georgia legislators in 1956 regarding the Georgia state flag?
Mrrafil [7]

Answer:D

Explanation: Per the quotes of the flag designer John Sammons Bell, the 1956 State Flag was created to honor the Veterans of Georgia who were passing away in huge numbers, and it was to be a memorial to them and their service. Other politicians who helped get the flag changed stated the Flag should be adopted because no other state suffered so much as did Georgia because of Sherman's scorched Earth policy of the burning of Atlanta and March to the Sea.

The Flag change also was part of the lead up to the Civil War centennial initiated by President Eisenhower.

All of the other 'answers' are silly, misleading and totally bogus
