To obtain a scan using the positron emission tomography technique, a patient is injected with (or ingests) a low and harmless dose of a short-lived radioactive glucose.
<h3>
What is Positron emission tomography?</h3>
This refers to a type of imaging technique which employs the use of radioactive substances in other to measure the metabolic activity of the cells of body tissues.
A scan using this technique is obtained by injecting the patient with a low and harmless dose of a short-lived radioactive glucose so that a picture of where the glucose being used in the body is visible and helps to detect cancerous cells etc.

Answer:
Otitis media is generally caused by dysfunction of the Eustachian tube, which can be due to Pharyngitis.
Explanation:
The otitis media is an infection or inflammation of the middle ear and is mostly caused by the inflammation of the mucous membranes in the nasopharynx leading to dysfunction of the Eustachian tube. This can be caused due to a upper respiratory tract viral infection or streptococcal pharyngitis (strep throat) or due to some allergy.
Pharyngitis or sore throat is a type of inflammation caused by upper respiratory tract viral infection.
Therefore, Otitis media can be caused by Pharyngitis and thus it is associated with it.
Answer: dependency is more likely in cultures where access to alcohol is carefully controlled.
Explanation:
Studies have shown that in cultures where access to alcohol is carefully controlled and viewed as a sign of adulthood, dependency is more likely than in cultures where alcohol is used in religious and ceremonial activities.
This has been put down to people tending to abuse alcohol when they get access to it as opposed to cultures where it is readily available.

Answer:
Azithromycin will be in your system for <u>around 15.5 days</u>, after the last dose.
Explanation:
Azithromycin has an elimination half-life of 68 hours. The prolonged terminal half-life is thought to be due to extensive uptake and subsequent release of drug from tissues. It takes around 5.5 x elimination half life's for a medicine to be out of your system. Therefore it would take 374 hours about 15.5 days (5.5 x 68 hours) for it to be eliminated from the system. So it'll be in your system for that period of time, after the last dose.
