Modified breath‐hold compressed‐sensing 3D MR cholangiopancreatography with a small field‐of‐view and high resolution acquisition: Clinical feasibility in biliary and pancreatic disorders

“…Recently, a compressed‐sensing (CS) accelerated MR technique with sparsity‐based reconstruction of highly undersampled data has emerged, which has shown great potential in accelerating MR data acquisition . Several pioneer studies have tested the clinical feasibility of CS‐accelerated 3D MRCP, and the initial results were encouraging.…”

“…Recently, a compressed-sensing (CS) accelerated MR technique with sparsity-based reconstruction of highly undersampled data has emerged, which has shown great potential in accelerating MR data acquisition. [7][8][9][10][11][12] Several pioneer studies have tested the clinical feasibility of CSaccelerated 3D MRCP, and the initial results were encouraging. Volumetric 3D MRCP in a single breath-hold became feasible, and the general image quality was reported to be similar or even superior compared to the routine navigatortriggered (NT) protocol.…”

MRI in donor candidates for living donor liver transplant: Technical and practical considerations

“…However, 3D T 2 ‐weighted MRC may perform poorly in patients with an inconsistent respiratory cycle, resulting in an excessively prolonged acquisition time and substantial motion artifact . To reduce the scan time, techniques such as compressed sensing that undersamples the k ‐space and GRASE (gradient and spin echo) that combines the spin echo and gradient echo have been incorporated with 3D MRC . These newer techniques are available from most of the major vendors.…”

“…78 To reduce the scan time, techniques such as compressed sensing that undersamples the kspace and GRASE (gradient and spin echo) that combines the spin echo and gradient echo have been incorporated with 3D MRC. 83,84 These newer techniques are available from most of the major vendors. Currently, the effects of the fast imaging techniques have not been investigated yet in living liver donors, but they seem promising in light of the reduced motion artifact.…”

Accelerated whole brain intracranial vessel wall imaging using black blood fast spin echo with compressed sensing (CS-SPACE)

“…CS has been used to accelerate black blood extracranial T1 weighted carotid plaque imaging using 3D gradient echo sequences [16, 17], and also for the T2 mapping of the carotid plaque using a 3D fast-spin-echo (CUBE) technique [18]. The combination of CS and PI has also been used in different clinical applications, including the breast [19], carotid plaque [20], abdomen [21] and musculoskeletal disorders [22, 23]. …”
