Purpose:
To analyze a radiography program's use of the Health Education Systems Incorporated Admission Assessment (HESI A2) and the HESI Exit Exam for preparing graduates to take the American Registry of Radiologic Technologists (ARRT) certification and registration exam for radiography.
Methods:
The program collected exam scores from the HESI Exit Exam for radiography and the ARRT radiography certification and registration exam for a 10-year period. The study included scores of 171 students who graduated from the radiography education program. The program administered the HESI A2 exam during the last 4 years of the study period, which included 81 students. The authors analyzed the data using mean differences, correlations, and a receiver operating characteristic curve analysis.
Results:
The correlation of HESI A2 scores with final HESI Exit Exam scores was 0.58 and with ARRT exam scores it was 0.64, which are extremely high correlations in an admissions context. The correlation of final HESI Exit Exam scores with ARRT exam scores was 0.73, which also is a strong correlation for predicting ARRT exam success. More than 94% of students who scored above the recommended performance level of 750 on the second HESI Exit Exam passed the ARRT exam on the first attempt. A receiver operating characteristic curve analysis indicated that the final HESI Exit Exam score was a strong predictor of pass or fail status on the ARRT exam.
Discussion:
The HESI A2 and Exit Exam are effective measurement tools when used with cogent testing policies. Such policies include strong proctoring practices such as rigorous in-person testing or online proctoring with an attentive, live proctor. Having practice exam results count for a reasonable amount of a course grade (eg, less than 30%) also could be a good policy for the HESI Exit Exam.
Conclusion:
The HESI A2 and Exit Exam are effective tools for helping radiography educators select students for admission and measure student knowledge to help achieve positive certification outcomes.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
