Are white-matter hyperintensities found on MRI biomarkers for TBI?

By Kate Madden Yee

White-matter hyperintensities found on high-resolution FLAIR images on 3-tesla MRI aren't necessarily biomarkers for mild traumatic brain injury (TBI).

7-minute shoulder MRI scans are feasible

A commercially available deep-learning (DL) algorithm can enable high quality seven-minute shoulder MRI exams.

February 18, 2025

Images in an 18-year-old man with recurrent dislocations of the right shoulder. (A, B) Unenhanced coronal, (C) axial, and (D, E) sagittal deep learning super-resolution threefold parallel imaging -- accelerated turbo spin-echo MRI scans were obtained at 3-tesla field strength. (A) Coronal T2-weighted fat-suppressed (FS) and (B) coronal proton density (PD)-weighted MRI scans show a nondisplaced superior labral tear (arrows). (C) Axial proton density-weighted fat-suppressed, (D) sagittal T2-weighted fat-suppressed, and (E) sagittal T1-weighted MRI scans show continuation into a nondisplaced anteroinferior labral tear (arrows). All seven readers correctly diagnosed the arthroscopy-validated findings. (F) An arthroscopic photograph shows the anteroinferior labral tear (arrow). Image and caption courtesy of the RSNA.

New AI model successfully segments anatomic structures in MR images

Wash. bill would loosen supervision rules for RTs, MRI techs

By AuntMinnie.com staff writers

The state of Washington is considering a bill authorizing diagnostic radiologic technologists (RTs), therapeutic RTs, and MRI technologists to perform intravenous contrast procedures under "general supervision."

Ultrafast MRI exam bests standard MRI for classifying breast cancers

By Amerigo Allegretto

An ultrafast MRI-based radiomics exam performs just as well as standard MRI and isn’t dependent on radiologist experience.

January 28, 2025

Ultrafast and standard MRI in a 30-year-old woman with triple-negative invasive ductal carcinoma. (A) Ultrafast MRI taken 16.8 seconds after contrast agent injection. (B) Standard MRI taken 58.8 seconds after contrast agent injection. Both images show an oval-shaped, irregular marginated, rim-enhancing mass in the left outer breast. For 3D tumor segmentation, the entire enhanced tumor margins were drawn from top to bottom of each tumor in axial views of U2 phase postcontrast ultrafast MRI and the initial phase postcontrast standard MRI. Among the 14 ultrafast images, U1 is the first phase in which the signal intensity of the hotspot region of interest of the tumor is 10% higher than the average signal intensity of unenhanced images. U2 is the immediate next phase of U1 and the well-established tumor enhancement time.
