Radiologist Computer Screen X Ray

Imaging turnaround times continued to climb in 2024

The largest increases were found in ultrasound and x-ray.

(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.

MRI may help predict heart disease risk in patients with diabetes

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

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.

CEM finds breast cancer at baseline, incidence screening

By Amerigo Allegretto

Incidence screening with CEM maintains high performance and may offer more benefits over baseline CEM screening.

July 28, 2026

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.

SPECT/CT viable over PET/CT for high-risk prostate cancer staging

Considering its broader accessibility, Tc-99m MIP-1404 CZT SPECT/CT may represent a practical alternative for primary staging.

Maximum intensity projection of Ga-68 PSMA-11 PET/CE-CT (A), Tc-99m MIP-1404 CZT SPECT/CT (B) and Tc-99m HDP CZT SPECT/CT (C) imaging. Ga-68 PSMA-11 PET/CE-CT and Tc-99m MIP-1404 CZT SPECT/CT showing tracer uptake in lymph nodes below the iliac bifurcation and above, paraaortic and left supraclavicular, bone uptake in the right proximal femur and right scapula (arrows). Tc-99m HDP CZT SPECT/CT did not show any uptake suspicious for metastatic disease. No sclerotic lesions suspicious of metastases were detected by the CT component in any of the studies. Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (D) and Tc-99m MIP-1404 CZT SPECT/CT (E) showing uptake in lymph nodes in the left pelvic area below the iliac bifurcation (arrows). Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (F) and Tc-99m MIP-1404 CZT SPECT/CT (G) showing uptake in the right proximal femur, not detected by Tc-99m HDP CZT SPECT/CT (H), (arrows).
