CT lung screening rates show gradual upward trend
Participation in CT lung cancer screening programs among eligible individuals in the U.S. has been making modest gains over the past several years. The U.S. Centers for Disease Control and Prevention released on February 28 new survey findings with statewide rates as high as 16%.

CT CAC predicts risk of death in smokers
The presence of coronary artery calcium (CAC) on CT scans was associated with an increased risk of death from cardiovascular diseases, cancer, and all causes combined -- including for a subset of smokers eligible for CT lung cancer screening -- in a study published in the February issue of Atherosclerosis.

CT again tops DNA tests for early coronavirus detection
In a study covering more than 1,000 confirmed cases of the novel coronavirus disease, chest CT proved to be more accurate than the standard method of DNA testing for early diagnosis of the disease in high-risk individuals. The findings were published online February 26 in Radiology.

How can radiology help limit COVID-19 transmission?
The critical role of CT in diagnosing the novel coronavirus disease (COVID-19) has placed radiology at the frontline of disease management. Researchers discuss preemptive measures radiology departments can take to limit virus transmission in a February 19 article published in the Journal of the American College of Radiology.

CT proves vital for early diagnosis of COVID-19
Chest CT demonstrated better sensitivity than DNA testing at detecting coronavirus disease (COVID-19) in high-risk individuals upon initial presentation of symptoms in a new study, published online February 19 in Radiology. The findings affirm the vital role of CT in the early diagnosis of the condition.

Prehydration not needed before contrast CT of kidneys
Prehydrating patients who have chronic kidney disease before they undergo a contrast-enhanced CT exam has been the standard of care for years. But new research suggests that the practice results in unnecessary costs with few patient benefits. The findings were published online on February 17 in JAMA Internal Medicine.

Can ultrasound, 3D printing deepen maternal-fetal bonds?
When a pregnant woman sees her fetus on imaging scans, it can help strengthen the bond she feels with her unborn child, say researchers. They demonstrate how 3D-printed models based on ultrasound scans confirmed this concept in a study published online on February 8 in the Journal of Obstetric, Gynecologic, and Neonatal Nursing.

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.

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.
