Tracking Medical Exams Evolution Over Time with File Links
Medical professionals often need to quickly compare a patient's current exam results with previous ones. But when reports — laudos — are stored inside date-stamped folders alongside dozens of DICOM images, finding them means clicking through folder after folder, hunting for that one PDF.
The request was simple: "Can I just see all the reports for each exam type in one place?"
The Problem
In a health records project, exams are organized by type, then by date:
Ecocardiograma bidimensional com Doppler/
2019-10-30/
000_laudo.pdf ← the report
001_image_s0001_i0001.jpg
002_image_s0001_i0002.jpg
... (16 images)
2021-05-31/
000_laudo.pdf
... (14 images)
2023-10-25/
000_laudo.pdf
... (67 images)
2024-12-13/
000_laudo.pdf
... (many images)
2026-02-06/
000_laudo.pdf
... (75 images)
This structure makes sense for archival — each exam session is self-contained with its report and all associated images. But for a doctor doing a quick temporal comparison, it's painful. Opening five folders to see five reports is not efficient.
The Solution: Sutram's File Links
Sutram offers a feature called File Links — a content type that creates a read-only symbolic reference to an existing file. No storage duplication, no versioning complexity, just a pointer to the original.
Instead of duplicating files or restructuring the archive, File Links were used to create a new Laudos folder under each exam type:
Ecocardiograma bidimensional com Doppler/
2019-10-30/
2021-05-31/
2023-10-25/
2024-12-13/
2026-02-06/
Laudos/ ← NEW
2019-10-30.pdf → links to 2019-10-30/000_laudo.pdf
2021-05-31.pdf → links to 2021-05-31/000_laudo.pdf
2023-10-25.pdf → links to 2023-10-25/000_laudo.pdf
2024-12-13.pdf → links to 2024-12-13/000_laudo.pdf
2026-02-06.pdf → links to 2026-02-06/000_laudo.pdf
Now the Laudos folder shows every report sorted chronologically by filename. The evolution from 2019 to 2026 is visible at a glance.
Even better, Sutram's universal viewer makes navigating between reports seamless. Once a report is open, switching to the next or previous one is just a button click — no need to go back to the folder, find the next file, and open it again. This turns what used to be a multi-step folder dive into a smooth, sequential review of how results have changed over the years.
By the Numbers
Across all exam types, 10 Laudos folders were created containing 42 file links total:
| Exam Type | Reports |
|---|---|
| Ecocardiograma com Doppler | 5 |
| Doppler de vasos cervicais | 5 |
| Ultrassonografia de abdome total | 5 |
| Ultrassonografia de próstata | 5 |
| Ultrassonografia de tireoide com Doppler | 5 |
| Exames Laboratoriais | 8 |
| Teste ergométrico | 2 |
| Cintilografia (estresse) | 1 |
| Cintilografia (repouso) | 1 |
| MAPA | 1 |
The naming convention uses the exam date as the filename (2024-12-13.pdf), making it immediately clear which report is which — no need to open the file to check.
Why File Links?
Other approaches were considered:
Moving files would break the self-contained exam folder structure
Copying files would waste storage and create sync headaches
Shortcuts/aliases are OS-specific and don't work in a web-based system
File Links offer the best of both worlds: the original structure stays intact for archival purposes, while doctors get the centralized view they need for clinical work. And because they're just references, adding a new exam report takes seconds — just one more file link.
