Hypothesis
Is the performance of the CAD tool RENEX equivalent to that of expert readers in diagnosing renal obstruction?
Conclusion
Log-linear modeling showed that RENEX was equivalent to any expert in rating kidneys, particularly in the obstructed and non-obstructed categories.
Supporting Evidence
- RENEX showed beyond-chance agreement with expert consensus in non-obstructed and obstructed readings.
- Pairwise agreement between experts and RENEX was not significantly different.
- The log-linear analysis provided additional evidence that RENEX can assist in interpreting diuresis renography studies.
Takeaway
This study found that a computer program for diagnosing kidney problems works just as well as human experts.
Methodology
Log-linear modeling was used to analyze a database comparing CAD interpretations with expert consensus on kidney scans.
Limitations
The study relied on previously published data and did not have a gold standard for comparison.
Participant Demographics
The study included 95 patients (55 males and 40 females) with a mean age of 58.6 years.
