Abstract:
Discrepancy or quality improvement meetings are good practice and are now commonplace in most Radiology Departments, with the aim of improving diagnostic accuracy, preventing recurrent and common mistakes, improving the radiological report and thereby improving patient care. A total of 122 cases were assessed from a two-year period. This review highlights some of the more common, recurrent and important issues encountered within a general hospital with an emphasis on learning points and review areas.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
