Chronic internal carotid artery occlusion (CICAO) is an important cause of ischemic stroke, despite patients receiving aggressive medical therapy [1,2]. Several studies have demonstrated that endovascular recanalization is a feasible treatment option for carefully selected patients with symptomatic chronic internal carotid artery occlusion (CICAO), with successful recanalization reducing the risk of subsequent ischemic events by approximately 80 % compared to medical therapy alone or unsuccessfu…

Diffusion tensor imaging has prognostic value on return to play in hamstring injuries: A prospective cohort study
Hamstring muscle injuries are highly prevalent in sports and result in varying rehabilitation times [1,2]. The assessment of muscle injuries is based on clinical examination and qualitative conventional magnetic resonance Imaging (MRI) scoring systems, such as the Modified Peetrons grading and British Athletics Muscle Injury Classification [3–6]. Determining the return to play (RTP) prognosis following hamstring injury remains difficult. There is conflicting evidence for the use of conventional …

Evaluation of photon-counting CT-derived attenuation parameters for noninvasive liver fat assessment
To evaluate the diagnostic performance of multiple photon-counting CT (PCCT)-derived parameters for hepatic fat quantification, using MRI-derived proton density fat fraction (PDFF) as the reference standard.

Deep-learning derived detailed measures of body fat distribution and cardiovascular outcomes in non-dialysis dependent chronic kidney disease: The multi-ethnic study of atherosclerosis
An obesity paradox, i.e., an association between high BMI and reduced all-cause mortality, has been reported in patients with non-dialysis-dependent chronic kidney disease (CKD). We have recently developed and validated a fully automated deep-learning algorithm that can automatically segment and quantify detailed muscle and fat distributions from any conventional chest CT. Here, we generated these robust biomarkers in a study cohort with non-dialysis-dependent CKD (eGFR 15–90 mL/min/1.73 m2, Sta…

Female reproductive tract obstruction and its imaging mimics – A pictorial review
Identification of female reproductive tract obstruction is important as it is associated with a range of gynecological and obstetrical issues. Knowledge of relevant anatomy and the imaging characteristics of associated abnormalities can facilitate accurate diagnosis and guide appropriate clinical management [1–3].

Radiomics analysis of contrast-free synthetic MRI and apparent diffusion coefficient for early predicting neoadjuvant chemotherapy response in breast cancer
Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among women globally [1]. Neoadjuvant chemotherapy (NAC) had become a standard treatment for locally advanced breast cancer during the past decades [2]. Achieving pathologic complete response (pCR) following NAC is a predictor of an improved disease free and overall survival [3,4]. Thus, early and accurate pCR prediction can prevent needless toxicity in individuals who do not respond to treatment and…

Assessing internal carotid artery stenosis: Diagnostic Value of photon-counting detector CT angiography compared to Doppler ultrasound
Ischemic stroke constitutes a leading cause of morbidity and mortality, particularly in aging populations in which the prevalence of cardiovascular risk factors is rising [1,2]. Here, atherosclerotic stenosis of the internal carotid artery (ICA) is a major risk factor to ischemic stroke. Determining the need for carotid endarterectomy is crucial as the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and the European Carotid Surgery Trial provide evidence for the significant redu…

Evaluation of GPT-4o for multilingual translation of radiology reports across imaging modalities
Understanding radiology findings is essential for accurate diagnosis and effective treatment decisions. However, in today’s globalized world, patients increasingly present medical reports, including radiology findings, written in languages unfamiliar to their healthcare providers. These language barriers can hinder the integration of vital medical data into the clinical workup, leading to delays in diagnosis and suboptimal patient care [1]. Providing radiology reports in a language that healthca…

Exploring the correlation between effective dose and BMI-based size-specific dose estimate in CT angiography
Computed tomography angiography (CTA) is a widely used diagnostic tool, but concerns about radiation exposure necessitate accurate dose estimation. This study investigates the correlation between Effective Dose (ED) and Size-Specific Dose Estimate (SSDE) estimated from the patient’s body mass index (BMI) in CTA to evaluate the utility of SSDE-BMI as a patient-specific dosimetry parameter.
