Synthetic MRI

February, 2019

Synthetic MR imaging is a unique imaging, which enables the reconstruction in various sequence measuring the absolute properties of the tissue.  It is a technique that generates contrast weighted images from single acquisition. The basic principle of synthetic MR imaging is obtained based on quantification of single multiple echo and multiple dynamic scan. This includes the magnetic property of each tissue (T1, T2, and proton) using water molecules in the brain. A 3D single acquisition is used to create a set of (T1, T2, PD, FLAIR, and STIR), where the current technique has capability of creating structural MRI scans such as T1, T2, PD, FLAIR, and STIR and the technique is not applicable for acquiring DWI. Based on data, the software will synthetically recreate a contrast images, parametric maps, and segments the patient. This gives an adjustable feature of created images from the quantitative data once the MRI examination is completed. The popularity of Synthetic MR imaging is increasing due to its ability to adjust the images. The software will help to automatically calculate the brain parenchymal fraction that can be used to follow the brain atrophy in multiple sclerosis individuals. The clinicians will be able to measure the volume in term of tumors or lesions capture in the images. Further, the biomarker segmentation offers proper map display with relaxation values for brain (T1, T2, and PD).

The availability of Synthetic MR imaging in multiple product package has enabled surgeons and radiologists to speed up the workflow and increase patient throughput. Further, the availability of advanced product package consisting of contrast images, biomarker segmentation, parametric mapping, and volumetric measurements of brain has helped clinicians to offer more information than a conventional MRI present in the market. This will help the to have better objective decision support for diagnosing and follow-up of patients in future. There are multiple studies demonstrating the overall image quality comparing the conventional MR images with similar diagnostic utility for detecting range of brain tissue. The Synthetic MR imaging will reduce scan time and discomfort for individuals undergoing brain MR scan.
