The NSM-S15 product is an imaging device, and is intended to provide the physician with physiological and clinical information obtained non-invasively and without the use of ionizing radiation. The MRI system produces transverse, coronal, sagittal, oblique, and curved cross-sectional images that display the internal structure of the head, body, or extremities. The images produced by MRI system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin-lattice relaxation time (TI), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.
The indications for use are as follows:
Anatomical Region: Head, Shoulder, Breast, Wrist, Body, Spine, Knee, Extremities
Nucleus excited: Proton
Diagnostic uses: TI, T2, proton density weighted imaging
Diffusion weighted imaging
MR Angiography
Imaging processing
Imaging capabilities: Spin Echo (SE and 3D SE)
Fast Field Echo (FFE and 3D FFE)
Inversion Recovery (IRFFE, IRSE)
TI-FFE, T2-FFE, N-FFE (2D and 3D)
IR prepared TI-FFE3D
Dual Echo (DE) and Dual Spin Echo (DSE)
Dual Fast Field Echo (DFFE)
Turbo Spin Echo (TSE, 2D and 3D)
Single-shot TSE
Dual Contrast Turbo Spin Echo (DTSE)
Driven Equilibrium Turbo Spin Echo
IR TSE T2
Balance Fast Field Echo (B-FFE and 3D B-FFE)
Diffusion-Weighted Imaging with DWISE and Fast DWISE
Echo Planar Imaging (EPI)
Indications for use as stated in the FDA summary.
