Subminute fat-water-separated dual-echo automated spine survey iterative scan technique.
We developed and tested an automated sub-minute 3D dual-echo MR imaging technique producing fat-water color-encoded labeled images of the entire spine. Twenty-one subjects were scanned with the 2-point Dixon technique utilizing 2 contiguous 21-22 second breath-hold sagittal acquisitions. Fourteen alternating subject scan sessions were achieved in 58 minutes. In all cases, fat-water separation w...
متن کاملAutomated spine survey iterative scan technique.
Institutional review board approval, with waived consent, was obtained to develop a spine-labeling algorithm with retrospectively obtained deidentified HIPAA-compliant data. An automated magnetic resonance (MR) imaging technique to rapidly survey the entire spine and provide definitive numbering of disks and vertebrae was compared with neuroradiologist assignments in 50 cases. Contiguous two-st...
متن کاملPediatric MR imaging with automated spine survey iterative scan technique (ASSIST).
MR imaging automated spine survey iterative scan technique (ASSIST) provides an automated subminute, submillimeter, in-plane resolution survey of the entire spine in 2 contiguous sagittal fast gradient-echo breath-hold series with computer labeling of vertebrae and disks. The technique was prospectively tested in 13 school-aged children for a wide range of clinical indications. In all cases, im...

متن کاملAutomated Organ Detection in Water-Fat Separated Magnetic Resonance Imaging
Purpose: To cope with today’s healthcare challenges of providing cost-effective care with constant quality, advanced image analysis techniques that automatically extract anatomical information from complex, large image datasets are required [1, 2]. Examples of MRI applications that can benefit from such anatomical intelligence are: operator guidance for planning scans, organ-specific automated ...
