Hyperprolactinemia MRI Ordering Patterns in Alberta

Jennifer A. Mann's dataset contains 1,730 cases of patients with mild hyperprolactinemia who underwent MRI brain or sella scans in Alberta, Canada between 2012 and 2021. It was created to quantify the proportion of prematurely ordered MRIs without confirmatory prolactin testing. The data was last updated in April 2026.

Use Cases

• Classify MRI scans as 'clinically appropriate' or 'premature' based on clinical indication and patient prolactin levels.
• Analyze the association between patient age, sex, and scan year with premature MRI ordering using the provided group comparisons.
• Investigate the prevalence of abnormal MRI findings, such as microadenoma, within the premature cohort.
• Model the likelihood of premature MRI ordering using features like patient age and single prolactin measurement.
• Assess temporal trends in MRI ordering practices for hyperprolactinemia over the 2012-2021 period.

Strengths

• Contains 1,730 patient cases meeting specific inclusion criteria.
• Data spans a 9-year period from 2012 to 2021, providing longitudinal insight.
• Results include statistical comparisons (p-values, confidence intervals) between patient groups.

Limitations

• Dataset is small at 326.1 KB, indicating limited scope and likely few columns.
• Limited to a single geographic region (Alberta, Canada), reducing generalizability.
• Specific column names and raw data structure are not provided, limiting direct analysis.
