How often do we do the radiography audit?
The quality of radiographs taken within the practice should be audited annually using the standards in Table 1. If 70% of films fail to meet grade 1 standard, an action plan and re-audit are required.
What is an xray audit?
Auditing the quality of your radiographs is an essential part of running any dental practice. Regular auditing of your radiographs provides you with vital feedback to help you how you may improve your internal processes and reduce unnecessary exposure to radiation.
What is the acceptable maximum percentage of Grade 3 radiographs?
Standards: The National Radiological Protection Board (NRPB) guidance describes three grades of radiograph quality. Excellent (Grade 1 >70% of total exposures), diagnostically acceptable (Grade 2 <20%) and unacceptable (Grade 3 <10%).
What is the target rate for diagnostically acceptable digital images?
Images are either rated as ‘diagnostically acceptable’ (‘A’) or ‘not acceptable’ (‘N’). For digital imaging, no less than 95% should be categorised as ‘A’, and 5% as ‘N’. For film imaging, targets are 90% and 10% respectively.
What is a posterior bitewing?
Posterior bitewing – the film is positioned so that the distal aspect of the last erupted crown is visible on the film. Common errors: Inadequate stabilization of the film/bite tab combination causes the film to tilt/tip producing an image that is not oriented correctly.
Are most xrays AP or PA?
X-rays pass from the posterior to the anterior of the patient – hence Posterior-Anterior (PA) projection.
Why do radiologists need audits?
Why undertake an audit? Audit is an integral part of all clinical practice. Participation in audits show that you’re motivated and dedicated; not only to radiology but to the activities expected of a conscientious and desirable radiology trainee.
What are bitewing radiographs primarily used for?
Bitewing radiographs are indicated primarily to detect or monitor interproximal caries if the proximal surfaces of the teeth cannot be visually or tactilely examined.
What is the cause of most repeat imaging in digital radiography?
Six causes of rejection and repetition of digital radiographic images were identified: patient positioning errors, inappropriate selection of technical exposure factors, patient motion, presence of artefacts, improper collimation of the radiographic beam, and absence of permanent anatomical side markers (ASM).
