76% of healthcare educators shifted from AI fear to confidence after a 6-week hands-on CPD course, a qualitative study of 21 finds.
Adding strangulation to CT angiography screening criteria for blunt cerebrovascular injury (BCVI) increased utilization but did not improve detection: only 1.6% of patients screened for strangulation had BCVI vs 22.1% for other indications. (n=253)
Following a cruise-ship cluster, experts outline the 'silent' imaging signs of hantavirus pulmonary syndrome — a rare but high-mortality infection radiologists may be first to flag on chest imaging. Specific findings not quantified in source.
In 112 mammograms read by 10 residents, AI changed the BI-RADS category in 9.7% of assessments and altered diagnostic confidence in 19.2%, with upgrades outnumbering downgrades. Sensitivity for BI-RADS 4+ rose from 72.0% to 82.3% against an expert-consensus standard, though this…
On ankle MRI, chronic periosteal sleeve avulsion of the flexor retinaculum is easily missed on coronal views alone. The axial sequence clearly demonstrates the retinaculum wrapping around the medial malleolus tip instead of inserting sharply, with associated chronic scar plate a…
ACR Appropriateness Criteria for epigastric pain updated: evidence-based imaging recommendations now cover esophageal/gastroduodenal perforation, GERD, esophagitis, peptic ulcer disease, hiatal hernia, and post-reflux surgery scenarios, using GRADE methodology.
Part 1 of a CTisus educational series reviews the characteristic CT findings of focal nodular hyperplasia (FNH), emphasizing imaging features that allow radiologists to confidently distinguish this benign liver lesion from malignancy and avoid unnecessary interventions.
Chest X-rays may help predict future heart disease, a new study suggests. Researchers found that radiographic features can stratify cardiovascular risk, potentially turning every chest X-ray into an opportunistic screening tool. (exact figures not reported in source)
A new educational video reviews stroke complications like hemorrhagic conversion—masslike hemorrhage >1 cm with mass effect—and CT perfusion mimics, noting that patients with petechial hemorrhage may safely continue anticoagulation.
A 50-year-old with altered mental status had a non-contrast head CT reported as normal. CT angiogram revealed a focal occlusion of the distal basilar artery extending into the right P1 segment, with non-opacification of the proximal left PCA and left vertebral artery. DSA confir…
DWI-positive/FLAIR-negative mismatch on MRI suggests wake-up stroke symptom onset within 4–6 hours, potentially indicating eligibility for aggressive therapy.
Focal nodular hyperplasia (FNH) is a benign liver tumor with no malignant potential, requiring no surgery—a true 'leave alone' lesion. CEUS aids diagnosis. Most common in women aged 20-50, with an 8:1 female-to-male ratio, and no link to oral contraceptives.
Radiology Masterclass teaches how to identify mass effect on acute head CT: midline shift, sulcal effacement, ventricular compression, and herniation patterns. Essential for trainees and emergency radiologists.
On 27 radiology questions, DeepSeek-R1 scored higher than ChatGPT-o1 (mean 4.51 vs 3.73 on a 5-point scale, P<.001). When ChatGPT-o1 answered image-based questions, residents rated it lower than its own text answers, particularly for factual accuracy (mean 2.75). Both models sho…
The ACR Dose Index Registry (DIR) enables facilities, clinicians, and policymakers to benchmark and optimize CT radiation doses — a quality-improvement resource whose real-world impact on dose reduction is described qualitatively (exact figures not reported in source).
The Duke CSF-Venous Fistula Confidence Score (DCCS) — a structured reporting tool for grading certainty of CVF detection on CT myelography — is demonstrated via real-world cases in this AJNR video article, aiming to standardize interpretation of a diagnostically challenging SIH…
A JACR perspective argues that AI-assisted 'vibe coding' — generating functional code from natural-language prompts without deep programming knowledge — is redefining the expertise required to conduct radiology research, with implications for how the field trains and evaluates i…
Transarterial embolization for uterine arteriovenous fistulas: 100% technical success and 94.4% uterine preservation in 18 patients. Repeat embolization needed in 3; 1 ultimately required hysterectomy. Six patients achieved subsequent pregnancy. Retrospective, single-center, sma…
A new study reports gadolinium-based contrast agents are safe for vulnerable MRI patients, amid broader efforts to reduce gadolinium doses in contrast agents. Specific safety metrics and patient subgroups not detailed in source.
PI-RADS v2 score ≥5, alongside tPSA, cTx, and ALP, independently predicted bone metastasis in prostate cancer (n=325). Nomogram sensitivity 81.3%, specificity 74.5%; external validation: 78.4%/79.1%. Retrospective, two-center study.
RSNA's Imaging AI Certificate Program offers case-based, on-demand AI education built by radiologists for radiologists — covering foundational concepts through clinical application at self-selected depth.
57 Spanish neurology experts reach high consensus on anti-amyloid antibody use in Alzheimer disease—covering patient selection, ARIA monitoring, and treatment suspension—but flag equity of access and resource allocation as critical implementation hurdles.
The ACR has released a 2026 update to its Appropriateness Criteria for back pain in children, now including a plain-language patient-friendly summary to improve shared decision-making around imaging choices.
On MRI, LI-RADS LR-5 had higher PPV for HCC than KLCA-NCC definite HCC (93.9% vs 91.7%, p<0.001); on CT, PPVs were equal (92.9%). Corresponding probability categories should not be used interchangeably.
CTisus hosted a Facebook Live session discussing the transition from the old academic year to the new one, aimed at radiology trainees preparing for the upcoming year.
An inguinal plug from prior hernia repair can appear as a soft tissue pelvic mass, mimicking lymphadenopathy. Recognizing its characteristic triangular shape and location prevents false-positive cancer staging on CT and PET.
After decompressive craniectomy, a patient's own skull flap was temporarily stored in the anterior abdominal wall. On CT, this heterotopic bone appears as a calcified pelvic wall mass and should not be mistaken for a tumor.
The American College of Radiology has released a revised practice parameter for breast ultrasound performed by sonographers/technologists, with an effective date of June 10, 2026. No specific changes are detailed in the source.
An AI system may provide early breast cancer alerts from mammograms, according to research highlighted by AuntMinnie. Details, including the study design and accuracy, were not provided in the source.
A structured lecture on cerebral venous anatomy for radiologists: dural sinuses, cavernous sinus, superficial veins (Labbe, Trolard), deep veins (internal cerebral, basal veins of Rosenthal, vein of Galen), and a practical framework for neuroimaging interpretation.
