Abbreviated axial MRI images show a 7-mm irregular mass with irregular margin (arrows) in the right upper inner quadrant with early rapid enhancement (BIRADS 4). The participant was recalled and underwent an MRI-guided vacuum-assisted biopsy that showed sclerosing adenosis with microcalcifications and usual ductal hyperplasia and focal apocrine metaplasia. On the full-protocol images (not shown), the lesion was T2-weighted hypointense and showed diffusion restriction and washout kinetics in the delayed phase, characteristics that would not have reversed the decision to recall the participant.

Abbreviated MRI suffices in imaging dense breasts
By Amerigo Allegretto
Abbreviated MRI produces images at a comparable quality to that of multiparametric MRI in imaging dense breasts.

FAPI-SPECT/CT shows promise diagnosing gastrointestinal cancer
By Will Morton
FAPI-SPECT/CT is comparable to FDG-PET/CT for detecting lesions in patients with gastrointestinal cancer, a study shows.
May 19, 2025
Representative F-18 FDG-PET/CT and Tc-99m FAPI-SPECT/CT scans for five study patients with gastrointestinal cancer. FDG-PET/CT and FAPI-SPECT/CT images show that uptake occurred in metastatic lymph nodes (LNs) (patient number 50, D) and bone metastases (patient number 33, C). FAPI-SPECT/CT outperformed FDG-PET/CT in detecting liver metastases (patient number 3, A; and 15,B) and peritoneal spread metastases (patient number 27, E). Red arrows indicate foci additionally found by FAPI-SPECT/CT.

ISMRM: 4D flow MRI shows promise in chronic liver disease
By Will Morton
4D flow MRI could help identify fibrosis in patients with chronic liver disease, a study suggests.
May 16, 2025
Velocity streamlines of the portal vein measured using 4D flow MRI in a cirrhosis patient (a 62-year-old male), shown at the cardiac cycle time t = 84 ms. A cut-plane (white marker) matching the 2D flow image plane was used to quantify the 4D flow parameters in the main portal vein.
