Positron emission tomography scan (PET scan) Positron emission tomography (PET) is a nuclear imaging technique that creates detailed, computerized pictures of organs and tissues inside the body. A PET scan reveals how the body is functioning and uncovers areas of abnormal metabolic activity. During a PET scan, the patient is first injected with a glucose (sugar) solution that contains a very small amount of radioactive material. The substance is absorbed by the particular organs or tissues being examined.
Kneisler used a hailstone that measured 5.581 inches in diameter and weighed 1.68 lbs (a hailstone that was previously the largest measured in the U.S.) to calculate numbers necessary to estimate the size of the great hailstones in Revelation 16:21. Kneisler also assumed that the great hailstones would weigh 75 lbs in his analysis.
Hailstone could be state's largest on record. National Weather Service officials are investigating whether a hailstone that fell near Pawnee and Maize Road on Wednesday night is the largest recorded in Kansas. They're out looking at it right now, Chance Hayes, warning coordination meteorologist for the Wichita branch of the weather service, said Thursday.
