Introduction

Blueprint scan protocol

This document describes the guidelines and parameters for a shoulder CT scan (without contrast) following the Blueprint protocol and how the images are then processed in the Blueprint software.

The software creates a 3D model (using only the thin axial images) which the surgeon uses to “virtually” plan a shoulder replacement surgery utilizing the Stryker implant portfolio.

The thin axial images can be uploaded directly into the ordering physician’s Blueprint account via our secure cloud.

If the physician requests the images be uploaded to the Blueprint Cloud, please refer to page 7 for full instructions. Should you not be able to upload to the physician’s Blueprint account, the thin axial images may need to be burned to a CD or USB drive if the facilities PACS software will not allow the surgeon to download the entire axial DICOM series.

If you have any questions or require any assistance, please contact the Blueprint Team.

Patient preparation and scan instructions

Patient prep

Place patient supine on the table with humerus along the trunk of the patient. Arm/humerus is in the neutral position with the patient’s thumb up.

ISO-center the patient to avoid any out of field artifact. You may place a small pillow between the humerus and the trunk of the patient.

If the patient is unable to be positioned with the humerus along their trunk in neutral position, they can bend the elbow with the hand across the stomach.

Breathing instructions

Patient is to hold their breath. If a breath hold is not possible, shallow breathing is necessary to prevent motion.

Scan range

Without metal or a cement spacer in the shoulder
Start the scan a few slices above the AC joint, include the entire scapula and a few slices below the inferior angle of the scapula. The medial border of the scapula must be shown in the scan. The DFOV must be between 25 cm and 32 cm.

With metal or a cement spacer in the shoulder
Start the scan a few slices above the AC joint, include the entire scapula and 10 cm below the current implant (when possible) without exceeding the maximum DFOV of 32 cm. The medial border of the scapula must be shown in the scan.

Metal Artifact Reduction (MAR)/metal suppression software

We strongly recommend patients with metal to be done on CT scanners using metal artifact reduction/ suppression software, if available.

No gantry tilt. Reformatted images are not accepted in the software.

Note:
Axial slice thickness must not be greater than 1.25 mm. The entire glenohumeral joint and scapula must be scanned. See parameters for scan range and DFOV.

Blueprint scan protocols

GE scanners

Start the scan a few slices above the AC joint, include the entire scapula and a few slices below the inferior angle of the scapula. The medial border of the scapula must be shown in the scan.

If an implant is present, include the entire scapula and 10 cm below the current implant (when possible) without exceeding the maximum DFOV of 32 cm. The medial border of the scapula must be shown in the scan.

Important:

No gantry tilt
No contrast
All slices must have the same field of view and same slice spacing
Blueprint requires 1.25 x 1.25 mm axial images (do not exceed 1.25 mm)
No interval/overlapping slices
Matrix must be 512 x 512
No reformatted images will be accepted

Metal Artifact Reduction
We strongly recommend patients with metal to be done on CT scanners using metal artifact reduction/suppression software, if available.

If MAR is not available, increase KVP to 140.

Parameter Setting

Set DICOM tag “study description” to “Blueprint thin axials.”

Note:
If the scan is ordered as “bilateral shoulders,” each shoulder must be scanned separately.

Siemens scanners

Start the scan a few slices above the AC joint, include the entire scapula and a few slices below the inferior angle of the scapula. The medial border of the scapula must be shown in the scan.

If an implant is present, include the entire scapula and 10 cm below the current implant (when possible) without exceeding the maximum DFOV of 320 mm. The medial border of the scapula must be shown in the scan.

Important:

No gantry tilt
No contrast
All slices must have the same field of view and same slice spacing
Blueprint requires 1×1 mm axial images
No interval/overlapping slices
Matrix must be 512 x 512
- All Siemens scanners must be manually set to a squared matrix
No reformatted images will be accepted

Metal Artifact Reduction
We strongly recommend patients with metal to be done on CT scanners using metal artifact reduction/suppression software, if available.

If MAR is not available, increase KVP to 140.

Siemens scanners Parameter Setting

Set DICOM tag “study description” to “Blueprint thin axials.”

Note:
If the scan is ordered as “bilateral shoulders,” each shoulder must be scanned separately.

Toshiba/Canon scanners

Start the scan a few slices above the AC joint, include the entire scapula and a few slices below the inferior angle of the scapula. The medial border of the scapula must be shown in the scan.

If an implant is present, include the entire scapula and 10 cm below the current implant (when possible) without exceeding the maximum DFOV of 320 mm. The medial border of the scapula must be shown in the scan.

Important:

No gantry tilt
No contrast
All slices must have the same field of view and same slice spacing
Blueprint requires 1×1 mm axial images (do not exceed 1×1 mm)
No interval/overlapping slices
Matrix must be 512 x 512
Standard bone volumes are required
No reformatted images will be accepted
Only standard bone volumes are utilized for Blueprint scans
