Area 19 - AI Unlocks the Power of Oxygenation Sensitive CMR

Has this sequence been tested across different MRI vendors?

Answer: Yes, the sequence has been and proven reliable on all major MRI vendor systems (GE, PHILIPS, SIEMENS) with consistent results within field strengths and vendors.

Which field strength is optimal-1.5 Tesla or 3 Tesla?

Answer: While a 3 Tesla scanner provides a stronger BOLD effect, it is more prone to artifacts. A 1.5 Tesla scanner may offer fewer artifacts but with a slightly weaker BOLD sensitivity. Overall, there seems to be no significant difference in the clinical utility. While the BOLD sensitivity may be a good argument for 3T, the choice depends on the targeted balance between image quality and the strength of the BOLD effect.

Do I need to purchase a special sequence for oxygenation CMR?

Answer: No special purchase is required. The sequence is based on a standard SSFP sequence. You will however need to have the privileges to adjust several sequence parameters. A19 can provide specific guidance on these adjustments for optimal results.

Can my technologist perform this scan?

Answer: Yes, if your technologist has a basic understanding of cardiac MR, they should have no difficulty running the scan.

How many scans can be performed per hour?

Answer: With two sliding tables, to scan up to five patients per hour is possible, assuming efficient workflow and patient preparation.

What side effects should I expect?

Answer: Only minor side effects related to hyperventilation are expected. These include a dry mouth, lightheadedness and tingling. Any symptoms typically resolve within seconds once the patient resumes normal breathing.

Is it necessary for a physician to be present during the scan?

Answer: No, a physician’s presence is not required as no pharmacological substances are administered during the scan. The protocol is not associated with any significant adverse effects. This makes the process safe and convenient for both, the examiner and the patient.

Can I access a demo version of the software?

Answer: Not at this time. Due to regulatory and quality control reasons, we keep the analysis in-house. However, you can securely upload your data to us, and we will provide you with detailed results.
