In this study, researchers are looking at a different type of CT scan called a dynamic CT scan. You have this at the same time as the PET scan. The dynamic CT scan provides different information to a PET scan. The aim of the study is to find which type of scan is better at diagnosing early stage lung cancer.
Causes of Feline âMangeâ. As described above, mange in companion cats is caused by localized or generalized infestation by external parasites â most commonly Notoedres cati, Cheyletiella blakei and Otodectes cynotis. Cats develop disease by contact with infected symptomatic or sometimes asymptomatic carrier cats.
Three types of mites cause mange in dogs. Sarcoptic and Cheyletiella mites are highly contagious to humans and other animals. Both can cause much irritation and live comfortably on humans for long periods of time. Demodex mites are extremely common and normally harmless.
