Simultaneous Multislice Acquisition Using Rosette Trajectories
 
(SMART) The acronym for slice specific, multi angle, multi resolution, multi thickness scanning. This function allows the operator to individually customize the thickness, field of view and position of each slice in a multi angle study.

Sinc InterpolationMRI Resource Directory:
 - Calculation -
 
A method of interpolating image data by zero filling the high spatial-frequency components of the raw data so that after Fourier transformation the image matrix size has been increased. This method can significantly improve the image display.

Sinerem® is the brand name (same as Combidex®) for an ultrasmall superparamagnetic iron oxide (USPIO) to detect metastatic disease in lymph nodes. Metastatic nodes show less uptake of this MRI contrast agent, which results in less signal decrease and allows the differentiation of normal lymph nodes from normal-sized, metastatic nodes.
Lymph node imaging with Sinerem® is performed 24 to 36 hours after slow infusion. Normal lymph nodes turn black post contrast, namely on T2* weighted images. Metastatic lymph nodes remain unchanged in signal intensity.
Indication and Diseases: Cancer, Imaging for diagnosis, Lymphatic disorders.
See Ferumoxtran, and Classifications, Characteristics, etc.

Guerbet decided in 2007 to withdraw its Marketing Authorisation Application (MAA) for Sinerem.
