Details

This file combines data exported from the SECTRA radiology information system for two periods: 2012-2015 and 2016-2018. The dataset includes various types of radiological examinations such as X-rays, CT scans, MRI, ultrasound, and other imaging studies.

The examination_code field contains standard codes used within the healthcare system to identify different types of radiological procedures. These codes would need to be mapped to a reference table for detailed interpretation.

The report_text field contains the full radiology report text, which includes the radiologist's findings, interpretations, and conclusions. These are free-text narratives written by radiologists after reviewing the images.

Note

  • The SECTRA dataset provides valuable information about imaging studies performed on patients in the SEM cohort

  • The examination_id field has a format that typically starts with "SER" or "SEK" followed by alphanumeric characters

  • The time between referral_date, examination_date, and report_signature_date can be calculated to analyze workflow efficiency

  • The report_text field contains unstructured free text that would require natural language processing techniques for systematic analysis

  • This dataset can be linked to other SEM cohort datasets using the patient_id field
