The accelerated scan data was then processed using the AIR Recon DL software. Sagittal T2 images were essentially acquired twice, once with the local standard-of-care spine parameters and another using an accelerated protocol. The accelerated acquisitions were 72% faster for cervical scans and 62% faster for lumbar scans. The patients underwent both standard-of-care and either accelerated cervical (11 cases) or lumbar (15 cases) spine MRI on an Architect 3-tesla scanner (GE). The k-space-based tool provides denoising, reductions of artifacts (such as truncation ringing), sharpness enhancement, and improved contrast-to-noise and signal-to-noise ratios.

The study authors assessed the impact of the Air Recon DL image reconstruction software ( GE Healthcare) on image quality and scan times in 26 consecutive patients receiving cervical and lumbar spine MRI. 'We've been using deep learning for a while and we essentially went back and said, 'Let's look at the data acquired from an accelerated acquisition with a deep-learning reconstruction against the best approximation of clinical practice with a traditional technique,' ' he said.

In their study, the researchers sought to test their hypothesis that data acquired with an accelerated acquisition and reconstructed with a deep-learning method could yield comparable image quality to traditional, longer acquisition techniques. 'Deep-learning reconstruction provides gains in efficiency and improvement in the patient experience, portending the utility in routine clinical practice,' Tanenbaum said. In a study involving 26 patients, two neuroradiologists overwhelmingly preferred the image quality of the AI-reconstructed images to those acquired by standard-of-care methods that required much longer scanning time.

Researchers led by presenter Dr. Lawrence Tanenbaum of imaging services provider RadNet compared the performance of a commercial deep-learning algorithm with traditional methods for accelerating spine MRI in clinical practice. Ridley, staff writerĭecem- An artificial intelligence (AI) algorithm was able to enable spine MRI exams to be acquired as much as 72% faster while improving image quality, according to a presentation Thursday at RSNA 2021 in Chicago.
