6.1 Scanning a patient
6.1.1 Preparing the patient
An important step in a scan routine is well preparing the patient. This can contribute to a proper scanning
and to high quality images. The aim of such preparing is making the patient relaxed and in a good position
before and during the scan. Here are some suggestions that can help in this concern.
Room setting
Be sure that the scanner unit is clean and ready to scan ("Daily Check" and "Blank Acquisition" already
performed).
Preparing the patient
Ask the patient to remove if present any jewelry (earrings, necklaces), glasses and removable metallic
prothesis.
Accommodate the patient
After to have made accommodate the patient in the scanning area, set the scanner and the head support
system so as to frame the interested area and the neck/bust of the patient assumes an erected position.
Particular patients
A special care has to be taken in case of children, elderly people, claustrophobic people, physically or
mentally disabled.
Explanation of the examination
Please explain in short the scan routine to the patient, including the data collection process, the positioning
and scanning.
Proper breathing
Ask the patient to breathe slowly during the scanning (a slow and continuous breath helps from swallowing).
