Radiomics enhance the prediction of endovascular treatment success for femoropopliteal chronic total occlusions: a proof-of-concept study
Peripheral artery disease (PAD) affects as many as 230 million individuals worldwide and represents a major health concern [2]. Managing chronic total occlusions (CTOs) in these patients poses a substantial challenge in interventional radiology, largely due to the technical complexity and procedural risks involved in achieving successful endovascular crossing. Traditional wire and catheter methods often face significant challenges when attempting to cross chronic total occlusion (CTO) lesions, w…

Deep learning synthesis of DBT features from mammography for breast cancer diagnosis
Digital breast tomosynthesis (DBT) enhances diagnostic accuracy by minimizing tissue overlap seen in digital mammography (DM). However, the substantial number of images generated by DBT poses challenges for radiologists. The aim of this study was to enhance the diagnostic accuracy and clinical utility of DM for breast cancer diagnosis by leveraging advanced feature representations derived from DBT.

A novel deep-learning approach for coronary artery calcium scoring in contrast-enhanced spectral coronary CT angiography: A phantom study
Coronary artery calcium (CAC) is an essential indicator of coronary artery disease and the Agatston score serves as a reliable, reproducible, and widely accessible tool for risk assessment, prediction of adverse cardiovascular events, and treatment guidance, in both asymptomatic and symptomatic individuals [1]. The European Society of Cardiology and American Heart Association guidelines recommend a two-step computed tomography (CT) approach for coronary artery disease assessment for symptomatic …

Total knee radiomic feature atlas derived from magnetic resonance imaging segmentation: Insights into osteoarthritis incidence predictors
The rising incidence of knee osteoarthritis (KOA) poses a significant societal health burden and drives up medical care costs [1]. KOA progresses slowly and irreversibly across multiple structures, underscoring the need to improve our understanding of its pathogenesis and mechanisms [2]. Early identification of patients at risk of KOA onset and implementing proactive health strategies are crucial for comprehensive KOA management. Magnetic resonance imaging (MRI) is widely used to diagnose and ev…

Predictability of pretreatment contrast-enhanced MRI for pathological complete response after neoadjuvant chemotherapy in breast cancer patients: validation of the literature results
Breast cancer (BC) is one of the most common causes of cancer deaths worldwide [1]. Neoadjuvant chemotherapy (NAC) is increasingly used in patients with locally advanced BC and early-stage BC, aiming at reducing the tumor burden and thus improving eligibility for breast-conserving surgery. The pathological complete response (pCR) after NAC is considered a strong prognostic factor, as previous studies demonstrated that patients exhibiting pCR present better long-term outcomes than those without p…

Exploring pancreatic variability in BRCA carriers vs. Non-Carriers: A diffusion tensor MRI study
Pancreatic ductal adenocarcinoma (PDAC) is predicted to become the second leading cause of cancer-related mortality in the US within the next decade[1]. Surgical resection significantly improves prognosis, especially in early stage disease, with stage 1A PDAC patients achieving an 80 % 5-year survival rate [2–4]. Therefore, early detection of small asymptomatic PDAC or precursor lesions may improve overall survival [5,6]. While there is no population screening for pancreatic cancer, it is recomm…

Non-contrast MRI diagnostic protocol for pelvic venous disorders
Pelvic Venous Disorders (PeVD) are a group of chronic conditions caused by venous insufficiency in the pelvic region. Typical symptoms include chronic pelvic pain (>6 months of pain localized in the pelvis), dyspareunia, and lower back or leg discomfort. Additionally, some women may notice varicose veins in the vulvar area, commonly referred to as vulvar varicosities. These appear as swollen, bluish, or purplish veins on or around the labia majora [1,2]. Diagnosing PeVD can be challenging due…

Contrast-associated risks of iodine-based contrast media administration in breast imaging: Tips and overview of existing evidence – A narrative review
Contrast-enhanced mammography (CEM) and dedicated breast computed tomography (dBCT) are innovative techniques for evaluating breast tumour vascularity, providing valuable insights into tumour perfusion and enhancing breast cancer diagnosis accuracy [1]. CEM consists of a combination of low-energy (comparable to standard digital mammography [2]) and high-energy mammography images used to generate recombined images showing areas of contrast enhancement in a fashion comparable to breast MRI[3]. dBC…

Added value of 3D APT histogram analysis to DWI for predicting complete response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer
To evaluate the added value of amide proton transfer-weighted (APTw) imaging to diffusion-weighted imaging (DWI) using histogram analysis for assessing pathologic complete response (pCR) in patients with locally advanced rectal cancer (LARC) undergoing neoadjuvant chemoradiotherapy (NCRT).
