Radiological Report 400

Rubric safeguards patient-friendly AI-generated imaging reports

The rubric includes clarity, content, certainty, tone, and verbosity as core attributes.

$Example anteroposterior (AP) pelvic radiographs showing simulated acquisition artifacts used for stage 1 artifact-robust pretraining. Images are derived from the same AP pelvic radiograph from a 75-year-old woman with a CT- or MRI-confirmed left femoral-neck fracture. (A) Original AP pelvic radiograph. (B) Simulated grid or cable-shadow artifact. (C) Simulated motion-blur artifact. (D) Simulated sensor saturation or overexposure artifact.$

Representative multimodal ultrasound and endoscopic images in participants with Crohn's disease. Top row depicts findings in a 26-year-old male participant with Crohn's disease in remission. Bottom row illustrates findings in a 25-year-old male participant with severe active Crohn's disease. The terminal ileum was the most prominently thickened bowel segment in both participants. Paired images comparing imaging modalities are shown. (A, F) Grayscale US images of the longitudinal section; arrows in A indicate the intestinal wall. (B, G) Color Doppler flow images of the longitudinal section; the box outlines the region of interest. In these two images, blue represents venous flow, while red represents arterial flow. (C, H) Conventional CEUS images of the longitudinal section. (D, I) Vascular density maps derived from super-resolution CEUS of the longitudinal section; arrows in D indicate the intestinal wall, and the outline in I indicates the measurement area for quantitative analysis. (E, J) Corresponding endoscopic images in the participants.

AI cuts chest CT reporting time

Exploratory modeling suggested an approximate reduction of 0.5 full-time equivalent radiologist workload.

Example of AI-assisted pulmonary nodule detection and longitudinal volumetric assessment in a 65-year-old woman with peripheral arterial disease, a 24-pack-year smoking history, emphysema, and a family history of lung cancer. An incidental 8.5-mm right lower lobe pulmonary nodule is identified at CT angiography of the abdomen in July 2022 but does not receive follow-up. Subsequent imaging demonstrates interval growth, and CT-guided biopsy confirms stage IA lung adenocarcinoma. Contrast-enhanced axial chest CT images obtained on February 2, 2024, before robotic-assisted thoracoscopic segmentectomy, show a 12.1-mm spiculated right lower lobe pulmonary nodule. (A) Conventional contrast-enhanced axial chest CT image without AI assistance shows a 12.1-mm spiculated right lower lobe pulmonary nodule. (B) Corresponding CT image with AI-assisted pulmonary nodule detection, automated segmentation, and quantitative nodule assessment identifies a solid pulmonary nodule (nodule #1) measuring 13 × 8 (11) mm, with a volume of 739 mm3, a 45% volumetric increase compared with the previous contrast-enhanced chest CT performed on October 9, 2023 (510 mm3), and an estimated volume doubling time (VDT) of 216 days. (C) AI-generated longitudinal nodule analysis displays automated segmentation of the current (February 2, 2024) and previous (October 9, 2023) CT examinations, 3D nodule reconstruction, and quantitative volumetric assessment for longitudinal follow-up. The AI interface is displayed in the original software language (Dutch).

PCCT on par with MRI for diagnostic breast imaging

By Amerigo Allegretto

PCCT performed similarly to MRI for characterizing breast lesions and finding additional lesions.

Detection and extent of BI-RADS suspicious calcifications (amorphous, coarse heterogeneous, fine pleomorphic, and fine linear or fine linear branching) at axial photon-counting CT (PCCT) versus full-field digital mammography (first three images, craniocaudal view; last image, mediolateral oblique view). Calcifications found on mammography showed only partial visualization at ultrahigh-resolution PCCT (0.2 mm), while amorphous calcifications could not be distinguished from image noise. Corresponding abnormal enhancement was clearly depicted on contrast-enhanced PCCT images.

Self-interpreting by ordering clinicians tied to low-value imaging

By Amerigo Allegretto

Visits involving clinicians who self-interpreted all their ordered imaging had higher odds of imaging overall.

Bayer's PET agent meets endpoints in phase III cardiac amyloidosis study

Overall sensitivity was 94% (95% CI, 85% to 98%) and specificity was 86% (95% CI, 77% to 92%).

August 31, 2026

This figure shows fused I-124 evuzamitide positron emission tomography (PET)/computed tomography (CT) images from patients without amyloidosis and from patients with ATTR cardiac amyloidosis, early ATTR cardiac amyloidosis, light chain cardiac amyloidosis, gelsolin-mediated amyloidosis, and systemic organ amyloid. The columns represent radiological transaxial, sagittal, and coronal views except for the last row middle and far right columns, which are coronal projections. The blue asterisks represent physiological activity (tracer activity in the stomach and esophagus). The arrowheads represent pathological uptake. Note the small amount of cardiac uptake in the basal septum and the basal lateral walls (likely early ATTR cardiac amyloidosis), splenic uptake and pleural uptake in light chain amyloidosis, and cardiac and kidney uptake in gelsolin-mediated amyloidosis. The bright yellow color represents more tracer uptake.

Is nitroglycerin necessary prior to photon-counting CT?

Sublingual nitroglycerin is routinely administered before CCTA to induce coronary vasodilation.

August 27, 2026

Representative case from the non-nitroglycerin cohort. A 92-year-old man who did not receive sublingual nitroglycerin because of severe aortic stenosis. The Agatston coronary artery calcium score was 5438. (A) Curved multiplanar reformatted CCTA image reconstructed at 0.4-mm slice thickness using a Bv60 kernel and QIR strength 3 demonstrates diffuse multifocal mild luminal stenoses related to extensive calcified atherosclerotic plaque. (B) Invasive coronary angiography confirmed multifocal mild stenoses without evidence of obstructive coronary artery disease.
