(A) Ga-68 NK224 PET/CT maximum intensity projection image (left), axial PET/CT images (center), and axial CT images (right) in a 43-year-old female participant with lung adenocarcinoma show lesions in the right cerebellum (blue arrow), right frontal lobe (red arrow), and sternum (green arrow) with low, intermediate, and high tracer uptake, respectively. Photomicrographs (scale bar, 100 μm) with hematoxylin-eosin (H&E) staining (center bottom) and programmed death ligand 1 (PD-L1) immunohistochemical (IHC) staining (right bottom) show high PD-L1 expression in the sternal lesion (tumor proportion score ≥ 50%).

AI fracture detection device validated across three European hospitals

No differences in AI performance were observed across centers, and AI assistance was associated with higher reader sensitivity.

August 18, 2026

Artificial intelligence (AI) assistance facilitates correct fracture identification in cases initially missed by human readers. A representative case is shown using anteroposterior radiographs in a 29-year-old male patient with wrist trauma (suspected nondisplaced transverse scaphoid fracture). The reader’s initial unaided assessment (top) resulted in a missed fracture, whereas with AI assistance (bottom), the fracture was correctly identified. The green box represents the fracture location as predicted by the AI tool, the blue box represents the reference standard annotation, and the red dots represent individual reader annotations.

PET/MRI detects arterial inflammation in prostate cancer patients

Androgen deprivation therapy (ADT) is widely used in advanced prostate cancer, yet is associated with increased cardiovascular events such as stroke and heart attacks.

July 31, 2026

Representative axial fused F-18 FDG-PET/MRI images and corresponding anatomic MRI images from a patient imaged at baseline and after initiation of androgen deprivation therapy are shown. Each row displays a distinct vascular territory. White arrows indicate focal areas of increased tracer uptake within the arterial wall, where spherical volumes of interest (VOIs) were placed for maximum standardized uptake value (SUVmax) measurement. Additional VOIs were placed in the superior vena cava and inferior vena cava for blood-pool activity sampling. SUVmax values from the arterial VOIs were extracted on the corresponding PET images and normalized to the blood-pool mean standardized uptake value to derive the maximum target-to-background ratio.

AI cuts chest CT reporting time

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

September 1, 2026

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.

September 1, 2026

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

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.

PET outperforms CT in ovarian cancer

Peritoneal carcinomatosis in ovarian cancer is cancer that has spread from the ovaries to the peritoneum.

August 28, 2026

Comparison of contrast-enhanced CT (ceCT) and FAPI-PET in detecting peritoneal carcinomatosis in patient with advanced ovarian carcinoma. (A) ceCT shows subtle peritoneal thickening that is difficult to delineate. (B) Maximum-intensity-projection image demonstrating diffuse intense FAPI uptake corresponding to extensive peritoneal carcinomatosis. (C) FAPI-PET shows intense uptake corresponding with peritoneal carcinomatosis, with improved lesion conspicuity over ceCT.

Advanced ultrasound techniques improve soft tissue tumor evaluation

By Amerigo Allegretto

Both SWE and SMI can help distinguish benign from malignant soft tissue tumors.

August 26, 2026

Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.
