Imaging Referral

NavNX can generate a pre-filled imaging referral form that you can send to your radiologist. The referral includes patient details, clinical indication, and the required acquisition protocol — ensuring the radiologist captures the right scan for 3D surgical planning.

​
Generating a Referral

1

Open the case detail page

Navigate to the case you want to order imaging for.
2

Click Imaging referral

In the DICOM imaging card, click the Imaging referral… button.

Review and edit

A modal opens with pre-filled fields:
  • Modality — MRI (default) or CT
  • Urgency — Routine, Semi-urgent, or Urgent
  • Patient details — name, DOB, gender, MRN (from patient record)
  • Surgeon details — name, credentials, practice, phone (from your profile)
  • Examination — body region (auto-detected from procedure type), laterality, planned surgery date
  • Clinical indication — auto-generated from the procedure type and side
  • Additional notes — any special instructions for the radiologist
  • Acquisition protocol — automatically included based on selected modality
All fields are editable before download.

MRI Acquisition Protocol

When MRI is selected as the modality, the referral automatically includes the NavNX MRI acquisition protocol requirements:
  • Sequence: 3D DESS (Dual Echo Steady State) preferred
  • Slice thickness: ≤ 1.0 mm (0.5–0.8 mm ideal)
  • In-plane resolution: ≤ 0.5 mm
  • Slices: ≥ 100 covering the entire joint
  • Field strength: 3T preferred, 1.5T acceptable
A standalone MRI protocol PDF is also available from the DICOM imaging card or from Settings > Resources.
NavNX’s AI bone segmentation is validated on 3D DESS MRI at 0.3–0.8 mm isotropic resolution. Using the correct acquisition protocol is essential for clinical-quality 3D bone models.

​
CT Scans

For CT referrals, standard musculoskeletal CT protocols with thin-slice acquisition (≤ 1.0 mm) and bone algorithm reconstruction are sufficient. No special protocol document is required for CT.
The clinical indication is auto-generated from the procedure type and side — for example, “Pre-operative planning imaging for ACL Reconstruction, left knee.” Edit it to add specific clinical details.
