Digital twins in radiology: A systematic review of applications, challenges, and future perspectives
Digital twin (DT or DTs) technology has emerged as a significant innovation with transformative potential across various industries, particularly healthcare. Originating in engineering and manufacturing, DTs are dynamic virtual representations of physical entities that continuously adapt through real-time data integration, advanced analytics, and artificial intelligence (AI) [1]. In healthcare, DTs enable the simulation, prediction, and optimization of medical processes, thereby providing a robu…

Assessment of biventricular cardiac function using free-breathing artificial intelligence cine with motion correction: Comparison with standard multiple breath-holding cine
With the capability of accurate and comprehensive assessment of cardiac morphology and function, cardiac magnetic resonance (MR) imaging plays an important role in the diagnosis of a range of heart diseases [1]. The conventional balanced steady state free precession (bSSFP) cine sequence with breath-holding (BH) is a clinical reference standard for assessing ventricular volumes and function in cardiac MR [2]. However, this approach requires multiple BHs to complete a full scan and to avoid respi…

Letter to the Editor-referencing JCCT-D-25-00140- Racial referral bias in cardiac computed tomography: Differences, disparities or discrimination?
We thank Dr. Sharma and Professor Connolly for their interest in our study. We also congratulate them on their own data, demonstrating an absence of bias in their referrals for cardiac CT. It emphasizes the global need to recognize and understand the reasons for potential biases in clinical practice but demonstrates the potential ability to overcome bias. It also reinforces the importance for institutions to internally audit their practices as there may be unconscious biases amongst physicians o…

Effects and safety of the transradial artery approach for cerebral angiography: A comparative observational study
Conventionally,the transfemoral artery approach has been the primary approach for neurointervention. However, this approach has been associated with perioperative complications. Thus, the purpose of this study was to evaluate the safety and feasibility of the transradial artery approach in cerebral angiography.

Brain pulsation demonstrated by CSF flow artifacts on FLAIR images might be associated with brain function
The glymphatic system works to excrete waste products from the brain. If it breaks down, cognitive impairment can occur. The system is mainly driven by arterial and brain pulsation. Brain pulsation is recognized as cerebrospinal fluid (CSF) flow artifacts on fluid-attenuated inversion recovery (FLAIR) imaging. We investigated the factors associated with human brain pulsation.CSF flow artifact grade (score) was defined by comparing the highest intensity in a given region of interest (ROI) to thos…

What a New MRI Meta-Analysis Reveals About AI-Powered Hippocampal Segmentation and Alzheimer’s Disease
While AI-enabled hippocampal segmentation on MRI offered a 95 percent AUC for differentiating between Alzheimer’s disease and normal controls in a 27-study meta-analysis, it offered significantly lower sensitivity and specificity in differentiating mild cognitive impairment.

Which Doctors See the Fewest Patients per Hour?
(MedPage Today) —
A recent report was released on the average number of patients seen per hour by specialty, which ranges from 1 to over 15.
If that sounds like a lot, that’s because it is. Physicians and hospitals make money based on the…
