#MyRadGirlfriend No. 94: Something's fishy
Your average radiology reading room is a place where people work together in cramped quarters. That's why it's important to be considerate of others, especially at mealtime as Dr. Roth needs to learn, in the next installment of #MyRadGirlfriend.

#MyRadGirlfriend No. 92: The sacrifice
Radiology and laboratory medicine have similar goals -- delivering a diagnosis on a patient's condition. But the way each discipline goes about getting there can vary widely, as Andy discovers in the next installment of #MyRadGirlfriend.

#MyRadGirlfriend No. 89: Fair and balanced scheduling
In any radiology department, one of the jobs of the chief resident is to create a schedule that's fair and balanced. Dr. Subrahmanyam can't wait to get a chance at scheduling in the next installment of #MyRadGirlfriend.

Study overview. (A) Volumetric segmentation of the paraspinal musculature was performed for 1,316 participants. (B) Manual segmentation was performed, the results were compared with the volumetric segmentation results, and the Dice score and the intersection over union were calculated. (C) The three-dimensional segmentations from T1 through T10 were individually extracted and combined into a single volume for analyses. (D) Muscle volume and median muscle attenuation were derived from the segmentation volumes. (E) Analyses were performed to assess the correlation of the paraspinal muscle attenuation and volume with the bone mineral density and the ability to predict vertebral fractures. NIFTI = Neuroimaging Informatics Technology Initiative, 3D = three-dimensional.

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

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.

Bayer's PET agent meets endpoints in phase III cardiac amyloidosis study
By Will Morton
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.
