New criteria evaluates treatment response in bone metastases

RECIBM-defined response classifications showed high agreement with established criteria and reclassified 19% of patients.

July 7, 2026

Response Evaluation Criteria in Bone Metastases (RECIBM) and metabolic criteria were used to detect a complete response missed at anatomic assessment. A 76-year-old male patient presented with 1 month of hemoptysis and was diagnosed with small cell lung cancer and bone metastases. Baseline (July 2022) F-18 FDG-PET/CT images (A, maximum intensity projection image; B–E, axial images) demonstrate FDG-avid lesions in the left lamina of the first lumbar vertebra (L1) (straight yellow arrows; maximum standardized uptake value, 2.74; peak standardized uptake value normalized to lean body mass, 1.59) and left ilium (curved yellow arrows; maximum standardized uptake value, 3.68; peak standardized uptake value normalized to lean body mass, 2.28). After seven chemotherapy cycles (December 2022), follow-up PET/CT images (F, maximum intensity projection image; G–J, axial images) show complete metabolic resolution of bony lesions (L1: maximum standardized uptake value, 1.32, and peak standardized uptake value normalized to lean body mass, 0.85; left ilium: maximum standardized uptake value, 1.48, and peak standardized uptake value normalized to lean body mass, 0.82), without apparent osteolytic or osteoblastic changes at CT. Assessment was stable disease (SD) according to the University of Texas MD Anderson Cancer Center (MDA) criteria but complete response (CR) or complete metabolic response (CMR) according to RECIBM, PET Response Criteria in Solid Tumors (PERCIST), and European Organization for Research and Treatment of Cancer (EORTC) criteria. The patient was alive as of September 30, 2025.

PET/CT guides treatment in men with recurrent prostate cancer

F-18 fluciclovine and Ga-68 PSMA-11 PET/CT have similar benefits for sRT planning, in terms of improving cancer control without increased toxicity.

June 30, 2026

F-18 fluciclovine PET/CT images in a 59-year-old man with biochemical recurrence after prostatectomy (prostate-specific antigen level, 0.42 ng/mL; Gleason score, 5 + 4 = 9; T3BN1M0). (A) Coronal PET and (B) maximum intensity projection images show multiple retroperitoneal lymph nodes with abnormal radiotracer uptake (arrows). (C) Axial PET and (D) axial fused PET/CT images show the index lesion (arrow), measuring 13 × 10 mm, on the right precaval lymph node. The initial decision to offer radiation therapy to the prostate bed and pelvis was changed to a decision not to offer radiation therapy.

Stepped reminders boost CT lung cancer screening

Example cases illustrate the double-edged role of large language model (LLM) rationale quality. (A) A 50-year-old female patient with a palpable anterior chest wall mass (correct diagnosis: solitary fibrous tumor of the pleura). The LLM incorrectly suggested synovial sarcoma but provided a persuasive rationale (quality score: 4 of 5), describing a well-defined nodule at axial contrast-enhanced CT spanning the pleura and intercostal space with heterogeneous strong enhancement. Four of five readers (80%) accepted the incorrect suggestion. FDG = fluorodeoxyglucose. (B) A 61-year-old male patient with diabetes presented with cough, sputum, and dyspnea (correct diagnosis: mucormycosis). The LLM correctly suggested mucormycosis with an excellent rationale (quality score: 5 of 5), integrating the reverse halo sign on serial axial CT images and rapidly progressive cavitary lesions. Three of five readers initially selected incorrect diagnoses; after LLM output, all five selected the correct diagnosis (100% acceptance). Blue and orange reader icons denote high- and low-expertise readers, respectively.

Model confidence, reader expertise affect reader-LLM collaboration

DBT-based foundational model classifies breast density

By Amerigo Allegretto

DBT-DINO showed strong performance in classifying breast density from DBT images.

August 4, 2026

(A) Free-response receiver operating characteristic (FROC) curve for DBT-DINO and DINOv2 (Meta AI) on the detection task. DINOv2 achieved higher sensitivity than DBT-DINO across most false-positive thresholds. (B) Detection rates of DBT-DINO and DINOv2 for lesions that were ultimately found to be benign (n = 70) and lesions that were found to be cancerous (n = 66). Error bars represent 95% CIs estimated via patient-level bootstrapping with 1000 repetitions. Both models showed similar detection rates for cancerous lesions, whereas DINOv2 detected more benign lesions than DBT-DINO. (C) Example bounding box predictions for DBT-DINO and DINOv2 on the detection test set. Each image is a single two-dimensional section from a three-dimensional digital breast tomosynthesis volume; the first column shows a mediolateral oblique view, and the second and third columns show craniocaudal views. Both models struggled to detect very small lesions, such as the 3-mm-diameter lesion shown in the first column. FP = false positive.
