Patient Orientation Registry in System
- Set the patient orientation in system: Head First – Supine
Haste_mylo_4views
- Position the patient in head first supine position.
- Use head rest with support patient’s head.
- Both patient’s arms at side of body.
- Align the patient in Mid-Sagittal plane of the table.
- Position the transverse laser light beam at the level of patient’s forehead to start the neck topogram.
SCANNING PROTOCOL
- Topogram length: 512 cm
- Slice: 0.6 mm
- Scanning direction: Craniocoudal
- Tube position: Lateral
- Stop the topogram scanning when the scanning reach / pass over the T4 or shadow of heart.
Non Contrast
- Plan the Scan FOV (SFOV) box at topogram image
- Set the top line at the level of frontal sinus
- Set the bottom line at the level of arch of aorta
- Ensure the lateral line to cover patient’s neck outline.
- Remind the patient to stop swallow saliva during scanning to avoid blurry image.
Scanning Parameters
- kVp:
- mAs: Tube Current Modulation (TCM)
- Scanning Direction: Craniocaudal
- Scan Delay: 4 s
- Slice:0.6
- Image Comment: Non Contrast
- Pitch: 0.6
Reconstruction of Non Contrast
Contrast
Type of contrast used:
- Non-ionic iodinated contrast media
- 300 I mg/mol
Needle Placement Test:
- Flow Rate: 3.5 ml/sec
- Volume of Normal Saline: 15 ml
Contrast Injection:
- Volume of Contrast Media: 70 ml (depend on patient’s body habitus)
- Volume of Normal Saline: 50 ml
- Delay: 50 sec
- Method of injection: Contrast Injector
- Flow Rate:
- Contrast: 3.0 ml/sec
- Normal Saline: 3.0 ml/sec
Post Contrast Scan Planning
Neck IV
- Plan the Scan FOV (SFOV) box at topogram image
- Set the top line at the level of frontal sinus
- Set the bottom line at the level of arch of aorta
- Ensure the lateral line to cover patient’s neck outline.
- Remind the patient to stop swallow saliva during scanning to avoid blurry image.
