Opinion: Inappropriate use of abdominal x-rays
Many requests for abdominal x-rays don't ask a clear question of the interpreting radiologist, and some requests aren't even clinically indicated. Dr. Toni Anderson from Dublin has studied this issue and shares her experiences.

Lung cancer screening: How Croatia does it
Example case from test set with biparametric MRI data, reference segmentation, and output from AI system. The primary MRI assessment resulted in a PI-RADS 5 lesion in the left dorsal part of the peripheral zone and a PI-RADS 4 lesion in the right dorsal part of the peripheral zone (PSA of 11.6 μg/L). Targeted biopsies from both areas showed ISUP-grade 3. All images are from the same slice location, showing a part of both lesions. A T2-weighted (T2W) image. B Diffusion-weighted image with a b-value of 1,500 s/mm2. (C) Apparent diffusion coefficient map. (D) Reference segmentation with white areas representing tumor. (E) Softmax output from AI system. Inset in the lower left corner shows the detection map (cropped around the prostate) with red voxels representing softmax values of 0.99 and yellow voxels representing softmax values of 0.59. (F) T2W image with reference (D) and detection map (inset in E) overlayed, green represents areas in which both the reference and the AI output are positive (true positive voxels for AI), red only positive in reference (false-negative voxels for AI) and blue only segmented by AI (false-positive voxels for AI).

Postoperative 3D volume rendering of the fenestrated endograft reconstruction: 3D volume-rendered reconstruction obtained in Horos using the standard soft-tissue preset. The image displays the postoperative appearance of the fenestrated endograft and visceral stents, extending from the descending thoracic aorta to the iliac bifurcation, acquired during the follow-up CT angiogram one month after the procedure. The reconstruction shows patent visceral branches with well-perfused stents, absence of endoleak, and successful restoration of the previously disconnected left limb with adequate iliac perfusion.
