Image Interpretation
Disease/Condition consistent with diagnosis
OUTCOME ANALYSIS
If diagnosis not consistent a study is needed to examine the image interpretation process-outcome analysis

WILL NOT GRANT APPROVAL TO FACILITIES WOTHOUT PROPER QC PROGRAMS
PLEASE NOTE THE 10 STEP QA PROGRAM NOTED ON PAGE 459
QC
Monitors x-ray equipment
Ensures optimal image for Radiologist

Differentiate between the ten steps of a QA program versus the three steps of the QC
program.

ESE stands for
Compare the differences between scheduled processor maintenance, preventative processor
maintenance and nonscheduled processor maintenance.
