Approved on: 01 Feb 2019

Overview

This standard is concerned with the use of computed tomography (CT) equipment and procedures to produce images for diagnostic purposes. It includes selecting the most appropriate scan protocol depending on the individual's condition and clinical history. Key people are those involved in the individual's care and others involved in provision of services. Users of this standard will need to ensure that practice reflects

    in accordance with local protocols

    1. confirm the status of key people before the examination and, where

    their presence is required, adhering to local guidelines

    1. enter the identification details of the individual into the CT scanner

    or, if previously entered, check for accuracy

    1. accurately select all parameters required for the scan according to

    local scan protocols for the procedure, assess any required

    modifications and take appropriate action

    1. position the individual and adjust their clothing according to the

    protocols for the examination to be performed in a manner which allows

    an optimal outcome to be achieved while:

    16.1 recognising the individuals need to retain their dignity and self

    respect

    16.2 ensuring their comfort as far as possible

    16.3 preventing the appearance of artefacts

    1. check the room prior to making the exposure to ensure that only

    essential, protected persons remain with the individual, that all local

    protocols have been adhered to and take appropriate action if this does

    not occur

    1. commence the scan and monitor the individuals condition,

    compliance and well-being throughout the procedure and take action

    appropriate to their needs

    1. view the images on completion of the scan to ensure they are

    technically acceptable and suitable for diagnostic purposes

    1. create multi-planar reformats (MPR) from the relevant datasets as

    appropriate

    1. review images for clinical acceptability, take appropriate action,

    including further imaging if required

    1. monitor and record the individuals exposure to ionising radiation

    throughout the procedure according to local protocols

    1. following the preliminary imaging examination, inform the

    appropriate person if an abnormality is observed on the image which is

    likely to require further investigation or treatment

    1. provide the individual with information relating to the procedure and

    aftercare where necessary

    1. explain the process for obtaining results

    2. optimise, record, collate and prepare appropriate information,

    documentation and images for transfer or storage according to local

    protocols

    1. verify that the images have arrived/been stored according to local

    protocols

    1. recognise where help or advice is required and obtain this from

    appropriate sources
