Abstract

Compressed Sense (CS) is a technological innovation in the field of Parallel Imaging (PI) that allows to reduce up to 50% the acquisition time per single sequence, reducing the whole duration of the MRI examination, and is based on the application of 3 principles: Incoherent k-space subsampling, sparsification transform and nonlinear iterative reconstruction. The purpose of our work was to evaluate the application of CS to the MRI protocol of the female pelvis performed for infertility, evaluating its Temporal Resolution and Signal/Noise Ratio (SNR) compared to the classic PI technique SENSE. MRI exams were performed with RM 3T scanners (Philips Ingenia, Philips Healthcare, Netherlands Eindhoven). The female pelvis MRI protocol included the following sequences: 3D PelvisView T2, 3D PelvisView T1, DWI (b0 and b1000), mDixon 3D THRIVE with ev. contrast media. The parameters of each sequence, with the exception of DWI in which the CS is not applicable, are shown in comparison between the application of Sense and Compressed Sense. The CS allows to obtain at the same spatial resolution, a protocol with faster acquisition times, correcting the effect of aliasing from data subsampling compared to conventional SENSE. In conclusion, the application of CS could bring multiple advantages in the field of MR imaging in the diagnosis of infertility in women, optimizing the image quality and the duration of each individual examination.
