The only other obstacle to the wider use of PET-CT is the difficulty and cost of producing and transporting the radiopharmaceuticals used for PET imaging, which are usually extremely short-lived. For instance, the half-life of radioactive fluorine-18 ( 18 F) used to trace glucose metabolism (using fluorodeoxyglucose , FDG) is only two hours.
As of August 2008, Cancer Care Ontario reports that the current average incremental cost to perform a PET scan in the province is CA$1,000–1,200 per scan. This includes the cost of the radiopharmaceutical and a stipend for the physician reading the scan. [92] In the United States, a PET scan is estimated to be US$1500-$5000.
Rover states, "The annual costs of caring for a dog can range from $1,000–$5,225 a year, while the typical monthly cost of owning a dog lies between $80-$440. This is an annual increase of $100 ...
One clear advantage of PET-MR compared to PET-CT is the lower total ionising radiation dose obtained. For body PET-CT applications, the CT part of the examination constitutes approximately 60-80% of the radiation dose, with the remaining radiation dose originating from the PET radiopharmaceutical.

Boarding for a single dog here gets cheaper the more nights you stay — $89 for a single night, $84 per night for a 7-plus evening stay and $79 per night for stays of two weeks or more.
The radiation used in CT scans can damage body cells, including DNA molecules, which can lead to radiation-induced cancer. [148] The radiation doses received from CT scans is variable. Compared to the lowest dose X-ray techniques, CT scans can have 100 to 1,000 times higher dose than conventional X-rays. [149]
The dog was thinking, “I heard the word, now the object needs to come,” Magyari said. "Ball" was the most common vocabulary word among the dogs in the study. Several had words for "leash ...
