Is a PDF the right place to read images diagnostically?

No — diagnostic image reading happens in your PACS/DICOM viewer, which preserves full image fidelity, windowing, and measurement tools; a PDF flattens images and is not a diagnostic-grade viewer. So use PDFs for communication, reporting, teaching, and sharing — not for primary diagnostic interpretation. A PDF case report with annotated key images is excellent for conveying findings to a clinician, building a teaching file, or packaging a second opinion, but the actual read stays in the diagnostic environment. So treat the PDF as the communication and documentation layer around your work, with diagnostic interpretation remaining in the appropriate DICOM tools. This distinction matters clinically and is the honest framing for any "annotate images in a PDF" workflow.

How do I annotate key images in a PDF?

For communication and teaching, place the key images (exported from your imaging system) into a PDF and add markup — arrows, circles, labels, callouts — to highlight the findings you are describing, so a reader sees exactly what you mean. This annotation is for explanation, not diagnosis. Keep the images legible and the markup clear. Remember these images are PHI (patient identifiers may be embedded or visible), so handle them confidentially and de-identify for any teaching/sharing use that requires it. So annotate key images in the PDF to communicate findings clearly; the markup guides the reader to what matters, while the diagnostic reading was already done in your viewer. The PDF presents and explains; it does not interpret.

How do I assemble case reports?

A case report combines your narrative findings with the annotated key images and relevant context into a clear, navigable PDF, so assemble the report text and images in a logical order, with clear figure references and a clean layout. Merge the components into one document, bookmark longer ones, and keep it legible. The report communicates your findings to referring clinicians or for the record. As documents, clear and navigable is the goal; the clinical content is your professional work. So assemble case reports as clean, navigable PDFs pairing narrative with annotated images; a well-organised report communicates findings effectively, which is the purpose, while the interpretation behind it is yours.

How do I build de-identified teaching files?

Teaching files reuse interesting cases for education, and using cases for teaching generally requires removing patient identifiers, so de-identify rigorously: redact patient names, IDs, dates, and any identifying details from images and text (true redaction that removes the data), and check images for embedded/visible identifiers. Only after proper de-identification (and per your institution's rules and any required consent) should cases go into teaching materials. So build teaching files from de-identified cases — redact thoroughly and verify nothing identifying remains, since teaching use of patient images carries real privacy obligations. The PDF workflow helps assemble and redact; ensuring de-identification is complete and compliant is your responsibility.

How do I handle second-opinion and consultation packages?

A second-opinion or consultation package assembles the relevant report, key images, and history into one organised PDF for another radiologist or clinician, so merge the components in a logical order, ensure completeness, and deliver it securely (these contain PHI). Keep it navigable so the consultant can review efficiently. Note that for the consultant's own diagnostic review, the original DICOM images (via appropriate sharing) are preferable to flattened PDF images — the PDF package is the report/communication wrapper. So assemble complete, navigable, securely-delivered consultation packages; the PDF organises and communicates, while diagnostic-grade review of the images themselves should use proper image sharing where needed.

How do I protect PHI throughout?

Radiology documents and images are PHI under HIPAA (and equivalents), so handle them with strict confidentiality: store encrypted with access limited to authorised staff, transmit through secure channels, redact identifiers with true redaction for any teaching or sharing that requires de-identification, and follow your institution's privacy policies. Be especially careful with images, which can carry embedded identifiers. Process documents with tools that keep files local rather than uploading PHI to an unvetted service. So protect PHI at every step — encryption, access control, true redaction/de-identification, secure transmission, and careful tool choice — because radiology data is sensitive health information, and its protection is both a legal obligation and a professional duty.

Is it safe to build these with an online tool?

Radiology reports and images are PHI, so prefer a tool that processes files locally. ScoutMyTool assembles case reports, annotates, redacts (true removal), and exports annotations entirely in your browser tab, so PHI never leaves your machine. Never upload PHI to a cloud tool without a proper agreement; confirm the tool does not upload, follow HIPAA/your institution's rules, and keep diagnostic reading in your PACS/DICOM viewer.

PDF for radiologists: case reports and image annotations

By ScoutMyTool Editorial Team · Last updated: 2026-05-22

For radiologists, PDFs are the communication layer around the work: case reports with annotated key images, teaching files, second-opinion packages, and report-outs to clinicians. One honest point up front — diagnostic reading stays in your PACS/DICOM viewer, which preserves image fidelity and measurement tools; a PDF flattens images and is for communicating, teaching, and sharing, not primary interpretation. And everything here is PHI, demanding strict handling and rigorous de-identification for teaching. This guide is the radiologist’s PDF workflow — annotated case reports, de-identified teaching files, consultation packages, and PHI protection — with the diagnostic read kept where it belongs.

The documents involved

Document	Use	Key trait
Case report	Communicate findings	Clear; with annotated key images
Annotated key images	Highlight findings	Markup for communication; PHI
Teaching file	Education	De-identified; organised
Second-opinion package	Consultation	Assembled; complete; secure
Referral / report-out	To clinicians	Clear; navigable; delivered securely
Case archive	Record, teaching	Organised; PHI-secured; retained

Step by step — a radiology communication workflow

Keep diagnostic reading in PACS/DICOM. The PDF is for communication and teaching, not primary interpretation.
Annotate key images for communication. Arrows/labels on exported key images to highlight findings — markup, not diagnosis (export with Export Annotations for review summaries).
Assemble navigable case reports. Merge narrative + images with Merge PDF, clear figure references — the patient-facing clarity in PDF for medical staff.
De-identify teaching files. Redact identifiers with true redaction from text and images; verify nothing identifying remains.
Build secure consultation packages. Complete, navigable, securely delivered; share DICOM for the consultant’s own read where needed.
Protect PHI throughout. Encrypt, restrict access, transmit securely — the safeguards in medical-record security and clinical-image consent practices.
Keep an organised, secured archive. Per case, PHI-protected, retained; process locally.

Medical-record security: protecting PHI.
PDF for medical staff: clinical documents and PHI.
PDF for orthodontists: clinical images and consent.
Add fillable form fields: structured report forms.
Real redaction: de-identifying for teaching.
Redact PDF tool: de-identify in your browser.

PHI protection is paramount; PDFs are not diagnostic. Radiology reports and images are PHI under HIPAA or equivalents; teaching use requires de-identification and may require consent. Diagnostic image interpretation must use appropriate PACS/DICOM tools, not a flattened PDF. This article covers handling the communication documents as PDFs.
