MRI assessment of extramural venous invasion in rectal cancer: a practical pictorial review

Sep 23, 2026

The authors aim to enhance the understanding and application of MRI assessment for extramural venous invasion (EMVI) in rectal cancer, highlighting its prognostic significance and the inconsistencies in its routine use. They provide a comprehensive pictorial review that covers the technical aspects of MRI detection, grading scales, and the clinical implications of EMVI findings for treatment decisions. The review emphasizes the need for careful interpretation to avoid common pitfalls and improve the reliability of EMVI assessments in clinical practice.

A radiology trainee's guide to perianal fistulas

Sep 23, 2026

This article serves as a comprehensive guide for radiology trainees on the evaluation of perianal fistulas using MRI, addressing the challenges of interpreting complex anatomy and imaging techniques. The authors aim to enhance understanding of key imaging features, anatomical landmarks, and the Parks classification system, while providing a structured framework for accurate reporting and communication with surgical teams. Ultimately, the review seeks to improve the consistency and quality of MRI assessments in clinical practice.

Early liver parameter increase after transjugular intrahepatic portosystemic shunt (TIPS): hepatic vascular risk factors and development of an exploratory prediction model

Sep 22, 2026

The authors aimed to investigate early laboratory changes following Transjugular Intrahepatic Portosystemic Shunt (TIPS) and their association with hepatic vessel diameters, as well as to develop a prediction model for identifying patients at high risk for excessive liver parameter increases. They found significant post-procedural increases in liver parameters, which were negatively correlated with the diameters of hepatic vessels, and developed a prediction model that identified key risk factors, achieving good predictive accuracy. This model may assist in optimizing post-procedural management for high-risk patients.

Biphasic CT clustering-based habitat radiomics predicts WHO/ISUP nuclear grade in clear cell renal cell carcinoma

Sep 22, 2026

The authors aimed to evaluate the effectiveness of a biphasic CT clustering-based habitat radiomics approach in predicting the WHO/ISUP nuclear grade of clear cell renal cell carcinoma (ccRCC) by analyzing different tumor subregions. Their findings indicate that specific subregions, particularly the tumor viable-necrosis transition zone, can provide diagnostic performance comparable to whole-tumor assessments. The study suggests that this method could enhance non-invasive characterization of ccRCC, although further validation is required before clinical application.

Spectral CT predicts initial bleeding risk in cirrhotic patients with esophagogastric varices

Sep 22, 2026

The authors aimed to develop a noninvasive multiparametric model using spectral CT metrics, venous morphometrics, and clinical biomarkers to predict the initial bleeding risk in cirrhotic patients with esophagogastric varices. Their study identified six independent predictors and demonstrated that the integrated model significantly outperformed individual predictors in accuracy, achieving an AUC of 0.912. This nomogram offers a promising tool for clinicians to assess bleeding risk in this patient population.

Abdominal CT findings on the day of death in patients with solid organ malignancies

Sep 22, 2026

The study aimed to identify abdominopelvic CT findings associated with imminent death in patients with solid organ malignancies. The authors found significant increases in pleural effusions and anasarca on CT scans performed within 24 hours of death, while other imaging and laboratory parameters showed no significant changes. These findings suggest a potential role for CT imaging in predicting imminent death, although further validation is needed.

MRI of spermatic cord lesions: a practical pattern-based approach

Sep 22, 2026

The authors aim to establish a practical, pattern-based MRI diagnostic approach for evaluating spermatic cord lesions, which are often challenging to differentiate from adjacent paratesticular masses. They propose a three-step method that involves determining the lesion's anatomical origin, classifying it based on specific MRI patterns, and integrating these findings to refine the differential diagnosis. This approach is designed to enhance the accuracy of MRI in identifying true spermatic cord lesions and guiding clinical management.

A knowledge-guided dual-path framework for automated liver MRI series classification

Sep 18, 2026

The authors aim to develop a robust automated classification system for liver MRI series to enhance clinical workflows, addressing limitations of current methods. They introduce a knowledge-guided dual-path (KDP) framework that combines CNN-extracted imaging features with metadata from DICOM headers, achieving high classification accuracy across 18 series categories. The system demonstrated excellent performance in both internal and external validation, indicating its potential for clinical integration.

Thickening of the internal anal sphincter: correlation with external rectal intussusception and associated features at MR proctography and anal manometry

Sep 17, 2026

The authors aimed to determine whether the thickness of the internal anal sphincter (IAS) can be reliably measured using endoanal MRI and if IAS thickening is linked to external rectal intussusception and anal manometry measurements. Their findings indicate that IAS thickening is significantly associated with external rectal intussusception and lower anal resting pressures, suggesting a potential relationship between these factors. The study demonstrates that IAS thickness can be consistently assessed via MRI, highlighting its relevance in the context of rectal intussusception.

Determining malignant potential of pancreatic intraductal papillary mucinous neoplasm with CT: interobserver variability and diagnostic performance

Sep 17, 2026

The authors aimed to assess the interobserver agreement and diagnostic performance of computed tomography (CT) in evaluating the malignant potential of pancreatic intraductal papillary mucinous neoplasms (IPMNs) according to the 2024 Kyoto guidelines, while also examining the influence of reviewer experience. Their findings revealed substantial interobserver agreement and good diagnostic performance, with less experienced reviewers benefiting more from guideline-based assessments compared to their experienced counterparts. Overall, the study highlights the importance of the 2024 Kyoto guidelines in enhancing diagnostic accuracy, particularly for less experienced radiologists.
