PET (or PET/CT) heart tracers are Rb-82, O-15 Water and F-18 FDG (fluordeoxyglucose), while Tc-99m MIBI, Tc-99m tetrofosmine and Tl-201 chloride are SPECT (or SPECT/CT) tracers.
A Dictionary of Units of Measurement. For information on a specific unit, click on the first letter of its name: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z. Answers to the three most frequently asked questions: How many micrograms (Âµg, ug or mcg) in a milligram (mg)? 1000 micrograms = 1 milligram, and 1000 milligrams = 1 gram. How can I convert from international units (IU) to milligrams or micrograms? Generally speaking, you can't. IU's measure the potency of a drug, not its mass or weight. What countries besides the U.S. have not adopted the metric system? Many U.S. teachers think the answer is Liberia and Burma (make that Myanmar). Let's give Liberia and Myanmar a break! All countries have adopted the metric system, including the U.S., and most countries (but not the U.S.) have taken steps to eliminate most uses of traditional measurements.
Milligrams can be converted to milliliters by converting milligrams to grams, and then converting grams to milliliters. There are 100 milligrams in a gram and 1 gram in a milliliter. The milligram (mg) and the gram (g) are both measurements of weight or mass in the metric measurement system. One gram is equal to 1000 milligrams. The milliliter (ml) is a measurement of volume in the metric measurement system. One milliliter is equal to 1 gram; there is a 1:1 ratio between the two units of measure. To convert an amount from milligrams to milliliters, divide the amount by 1000 to convert to grams, and divide the new amount by 1 to convert to milliliters.
