• Respiratory bellows
• Breath hold all scans on expiration - Common Indications
- Ischemic and non-ischemic cardiomyopathy (CMP)
- Position
- Supine
- Coil
- 32 channel Torso, GEMS Body Array, or Air Coil
- Landmark
- Nipple Line
Contrast Agent Parameters
| Contrast Agents | Dose | Injection Rate | Dose Timing Method and Scan Delay | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Gadopiclenol (VUEWAY) | 0.075 mmol/kg up to a calculated volume of 10 mL | 4 mL/sec | Injected during Perfusion. Consider injecting 1/3 of the contrast for Perfusion and after the scan is finished inject the rest at a rate of 1 mL/sec | ||||||||
| Saline Flush | 50 mL | 4 mL/sec | Immediately following gadolinium | ||||||||
| Comments | Breath hold | 3 Slice Mid Vent or if for Right Vent evaluation, then full stack copy and paste to acquire approx. 2 channel and 4 channel locs |
Short Axis, Double Oblique, Left Vent, Full Stack |
Long Axis Views. 2 channel 3 channel 4 channel 3 Slices non-contiguous |
Start scan, as soon as images start to appear, inject contrast at 4 mL/sec, once you visualize contrast have patient hold their breath for as long as they can | Inject contrast then wait 10 min for MDE. PREP TIME SCOUT–Use to determine TI time for MDE |
10-45 min after injection. Delayed enhancement Short Axis and Long Axis views |
Optional: 10-45 min after injection. Delayed enhancement Short Axis and Long Axis views |
Optional: 10-45 min after injection. Delayed enhancement Short Axis and Long Axis views |
Blood suppression must be done pre contrast |
Blood suppression must be done pre contrast fat nulling |
