In acute ischemic stroke (AIS) patients, the cortical vein opacification on computed tomographic angiography (CTA) imaging is usually asymmetric. To explore the correlation between CT perfusion parameters and cortical vein opacification evaluated by Hounsfield unit (HU) values, which is more accurately, and compare the predictive ability between them for outcome in AIS.
We scan the top radiology sources so you don’t have to.
From AI breakthroughs to imaging trends, we serve up real-time radiology insights.

VIPs outperforms established models for predicting post-TIPS prognosis in viral hepatitis-dominant cirrhosis
Transjugular intrahepatic portosystemic shunt (TIPS) manages portal hypertension complications in cirrhosis, but predicting post-TIPS outcomes remains challenging, especially in viral hepatitis-dominated populations.

Shap-interpretable predictive modeling of microvascular invasion and early recurrence in hepatocellular carcinoma using MRI habitat imaging combined with clinical features
To develop and validate an integrated model combining Gd-EOB-DTPA–enhanced MRI habitat imaging with clinical features for preoperative prediction of microvascular invasion (MVI) and early recurrence in hepatocellular carcinoma (HCC).

LET “Automated iliac artery tortuosity measurement: correlation does not equal agreement”
We read with great interest the article by Barb et al. entitled “Accuracy of fully automated iliac artery tortuosity measurements in patients with abdominal aortic aneurysm using deep learning” [1], published in the European Journal of Radiology. The authors are to be congratulated for providing a large, multicenter external validation of an automated approach addressing a complex vascular morphometric parameter.

Economic evaluation of bulk packaging and single-dose packaging of contrast media for contrast-enhanced CT
To conduct an economic evaluation of bulk-packaged contrast media in the CT rooms from multiple perspectives, assess its economic benefits, and provide a evidence to support hospital cost control and pharmacy management.

Impact of DSA-based postoperative cerebral blood flow cascades on outcomes in acute ischemic stroke patients undergoing successful endovascular thrombectomy
Half of patients with acute ischemic stroke caused by large vessel occlusion (AIS-LVO) fail to achieve functional independence after endovascular treatment (EVT), which may be related to the ineffective restoration of cerebral blood flow in ischemic brain tissue despite revascularization. Therefore, a comprehensive model to assess postoperative cerebral blood flow cascade (pCBF) may provide additional information for treatment.

Navigating the complexities of recall rates in breast cancer screening: Insights from the Irish national breast cancer screening programme
Recall rate (RR) is considered one of the key performance indicators of any breast screening programme[1]. This is the proportion of women undergoing screening mammography who are requested to return for further imaging. Recall is necessary to further evaluate lesions suspicious for breast cancer. However, there is a fine balance in maintaining high cancer detection rates (CDR) while minimising false positive recalls, where women are recalled for benign findings. Having a false positive recall c…

Establishing updated diagnostic reference levels for interventional radiology: a national Italian survey incorporating procedure complexity indices – Part II: interventional neuroradiology
The introduction of innovative technologies and devices in interventional neuroradiology (INR) has significantly improved specialists’ ability to treat a wide range of potentially life-threatening cerebrovascular conditions. [1]. However, using X-ray imaging devices involves stochastic risks and the potential for tissue reactions [2–5]. According to Sanchez et al [6], the radiation dose absorbed by patients undergoing interventional neuroradiology procedures may be sufficiently high to induce ra…

Exploring white matter abnormalities in different subtypes of spastic cerebral palsy using fixel-based analysis
Cerebral palsy (CP) is a neurological disorder characterized by impaired movement and posture, resulting from permanent brain damage before, during [1] or after birth [2]. About 80-90% of individuals with CP have spasticity, such as hemiplegia, diplegia, or quadriplegia depending on which limb is affected[3]. White matter damage in cerebrum, particularly periventricular leukomalacia (PVL), is commonly observed in individuals with spastic CP [4]. PVL may include focal and diffuse components, such…

Letter to the Editor regarding “Allergological evaluation of hypersensitivity reactions after administration of contrast agents: What the radiologist needs to know” – The role of polyethylene glycol in contrast-induced hypersensitivity
We read with great interest the recent article by Vega et al. titled “Allergological evaluation of hypersensitivity reactions after administration of contrast agents: What the radiologist needs to know” [1]. The authors comprehensively addressed diagnostic algorithms for contrast-induced hypersensitivity. However, we wish to highlight an aspect that warrants further consideration: the role of polyethylene glycol (PEG) in hypersensitivity reactions to sulphur hexafluoride microbubbles (SonoVue®),…
