Can radiologists’ eye-tracking data enhance AI?
By Will Morton
Integrating eye-tracking data that map how radiologists interpret x-rays into deep learning AI algorithms could be key to developing more “human-centered” AI.

PI-RADS optimizes MRI-based diagnostics for prostate cancer detection
By Kate Madden Yee
It's better to take Prostate Imaging-Reporting and Data System (PI-RADS) upgrading rules into account when it comes to deciding whether a patient with clinically significant prostate cancer needs a biopsy, researchers have reported.

ADC optimal cutoff reduces MRI-prompted breast biopsies
By Amerigo Allegretto
Applying point-of-care apparent diffusion coefficient (ADC) cutoffs from diffusion-weighted imaging could reduce MRI-prompted breast biopsies.
February 15, 2024
Apparent diffusion coefficient (ADC) measurements for benign and malignant BI-RADS category 4 or 5 lesions at MRI. (A, B) Benign BI-RADS category 4 lesion in a 55-year-old woman. (A) Dynamic contrast-enhanced MRI (DCE-MRI) scan shows a 12-mm, oval, circumscribed, homogeneous mass in the right posterior breast (arrow). (B) On the diffusion-weighted image, the lesion shows high diffusivity (arrow), with an ADC of 2.04 × 10-3 mm2/sec. Biopsy revealed benign fibroadenoma. (C, D) Malignant BI-RADS category 4 lesion in a 41-year-old woman. (C) DCE-MRI scan shows a 24-mm irregular, heterogeneous mass at the 3 o’clock position in the left breast (arrow). (D) On the diffusion-weighted image, the lesion demonstrates low diffusivity (arrow), with an ADC of 0.91 × 10-3 mm2/sec. Biopsy revealed invasive ductal carcinoma. All MRI scans are shown in the axial plane. (E) Box plot shows ADC measurements for 240 BI-RADS 4 and 5 lesions (63 malignant and 177 benign). Both prespecified optimal and conservative ADC cutoffs are indicated on the plot for reference: 1.53 × 10-3 mm2/sec (dashed line) and 1.68 × 10-3 mm2/sec (dotted line), respectively. All ADCs were calculated with maximum b value of 800 sec/mm2. The midline of each box shows the median value, and the box extends from first to third quartiles. The whiskers extend from the first and third quartiles to the smallest and largest values, respectively, if those values are within 1.5 times the IQR. If not, the length of the whiskers is limited to 1.5 times the IQR. Image courtesy of the RSNA.

Radiologists ‘compete’ on chest x-rays reads with and without AI
