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.
Mange is a skin disease caused by mites that affects many animals. In dogs, it is caused by one of three microscopic mites: Cheyletiella, Demodex, or Sarcoptes. Each one causes a different type of mange, with each presenting with similar yet varying degrees of symptoms. When the mange is present in large patches or all over the dog's body, this is known as generalized demodectic mange. 2  This type of mange produces bald, scaly patches of skin, which can be very itchy. 3  When the dog scratches, sores can form which are susceptible to unpleasant-smelling bacterial infections.
