Article Synopsis
  • The discrete shearlet transformation enhances edge detection in magnetic resonance imaging and is proposed as a superior sparsifying transform in low-rank plus sparse decomposition (L+S) problems.
  • Our study compares discrete shearlets with other transforms on dynamic contrast enhanced (DCE) scans and small bowel imaging, highlighting improvements in separating low-rank background from sparse components.
  • Results indicate that the discrete shearlet method yields more accurate motion estimates and consistent motility metrics between breath-holding and free-breathing scans, validating its efficacy for undersampled MR data analysis.

Article Synopsis
  • The study assessed radiation doses from PET/CT exams at a major hospital in Greece, focusing on data from 1014 patients.
  • The average computed tomography dose index (CTDIvol) was 5.5 mGy and the dose length product (DLP) averaged 483.3 mGy·cm, both within established literature ranges.
  • These findings can serve as a reference until national guidelines for radiation doses in whole-body PET/CT scans are developed.
