Brain PET scans reveal neuron loss in long COVID
The findings suggest that treatments aimed at boosting dopamine release could be repurposed to treat long COVID.
July 14, 2026
Representative participant from each group shown. C-11 DTBZ non-displaceable binding potential (BPND) in voxels quantitated with simplified reference tissue model 2. Color scale indicates C-11 DTBZ BPND from 0 (black) to 3.5 (red), with reduced C-11 DTBZ BPND observed in the long COVID case compared to both healthy controls.

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.

PET/MRI detects arterial inflammation in prostate cancer patients
By Will Morton
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.

Representative cardiac MRI strain images and analysis. Images in the two-, four-, and three-chamber views for strain analysis (left) and left ventricular global longitudinal strain (GLS) and global early diastolic longitudinal strain rate (eGLSR) curves (right) are shown. (A) Example images and GLS and eGLSR curves in a 37-year-old male participant with diabetes mellitus (DM) without events during follow-up after cardiac MRI. (B) Example images and GLS and eGLSR curves in a 45-year-old male participant with DM who had heart failure hospitalization during follow-up after cardiac MRI. In the left images, blue represents higher myocardial strain (higher absolute values of negative strain), whereas red represents reduced strain. In the curves, blue represents GLS, whereas orange represents eGLSR. The left y-axis denotes GLS (%), the right y-axis represents eGLSR (per second), and the x-axis denotes time (milliseconds). For these strain parameters, a lower absolute value indicates more severe myocardial functional impairment; accordingly, GLS and eGLSR were more impaired in participants with events compared with those without events.

CT radiation doses have fallen sharply over past decade
By Will Morton
The largest reductions appeared in chest examinations with contrast material, where diagnostic reference levels fell 31%.
July 28, 2026
Bar graphs show comparison of volume CT dose index (CTDIvol) (A) achievable doses (50th percentile) and (B) diagnostic reference levels (75th percentile) between 2014 (see reference 4 by Kanal et al) and 2025 (present study) for 10 common CT examination types performed without contrast (w/o) and with contrast (w/). Across all 10 adult CT examination categories, CTDIvol achievable doses and diagnostic reference levels generally decreased from 2014 to 2025, with the largest reductions for torso examinations (chest; abdomen-pelvis; and combined chest, abdomen, and pelvis), intermediate reductions for neck and cervical spine, and minimal change for head examinations.

Images in a 70-year-old asymptomatic woman with a prior excisional biopsy in the left breast yielding lobular carcinoma in situ 3 years earlier. Screening contrast-enhanced mammography (CEM) was performed, which was considered a prevalence screen as the woman had no prior breast MRI in the past 3 years and no prior CEM. (A) Low-energy (26–30 kVp) mediolateral oblique (MLO) and (B) craniocaudal (CC) views show surgical clips but no abnormality. (C) Recombined MLO and (D) CC images show an enhancing mass in the medial left breast (arrows). Biopsy revealed invasive lobular carcinoma. Size was 0.2 cm; tumor grade II/III; negative lymph nodes; and estrogen receptor–positive, progesterone receptor–positive, and human epidermal growth factor receptor 2–negative.
