Application of the Theory of Constraints to Radiology

Mar 19, 2026

The authors explore how the Theory of Constraints can be applied to optimize radiology workflows by identifying and addressing key bottlenecks that limit system throughput. They aim to determine whether constraints are primarily related to equipment or personnel, which could inform targeted interventions to enhance productivity in a resource-constrained environment. Ultimately, the study seeks to improve the efficiency of radiologic processes through strategic process improvements.

CT and MRI LI-RADS Treatment Response Assessment 2024: Core Concepts for Clinical Practice

Mar 19, 2026

The authors aim to address the challenges in imaging interpretation following locoregional therapies for hepatocellular carcinoma (HCC) by reviewing the updated 2024 CT and MRI LI-RADS treatment response assessment algorithm. This algorithm standardizes imaging interpretation and reporting, incorporating distinct criteria for different treatment modalities and ancillary MRI features to enhance the detection of tumor viability. The paper emphasizes the clinical applicability of these updates to improve patient management and treatment decision-making.

Imaging Findings in Parasitic and Vector-borne Infections of the Head, Neck, and Spine

Mar 19, 2026

The authors aim to highlight the importance of recognizing parasitic and vector-borne infections that can affect the head, neck, and spine, particularly as their geographic distribution expands due to various global factors. They emphasize the role of radiologists in accurately diagnosing these infections through imaging findings, which can be critical for timely and effective treatment. The paper provides an overview of relevant infections, their clinical presentations, and associated imaging features, supported by case examples.

The Many Faces of Nonthrombotic Pulmonary Artery Embolism

Mar 12, 2026

The authors aim to elucidate the various causes and imaging characteristics of nonthrombotic pulmonary artery embolism (NTPE), which can often be misdiagnosed as thrombotic pulmonary embolism (PE). They emphasize the importance of recognizing the distinct pathophysiologic mechanisms and clinical manifestations of NTPE to ensure timely and appropriate management. The paper serves as a comprehensive overview to enhance diagnostic accuracy through increased awareness of NTPE's diverse etiologies.

Splenic Artery Embolization: Tips, Tricks, and Current Standards of Practice

Mar 12, 2026

The authors aim to provide a comprehensive overview of splenic artery embolization (SAE), exploring its evolution from a treatment for traumatic splenic injuries to its current applications in various non-traumatic conditions. They discuss the anatomical considerations, technical aspects, and procedural guidelines necessary to optimize outcomes and minimize complications associated with SAE. Additionally, the paper reviews the indications for SAE, including management of hypersplenism, thrombocytopenia, and splenic aneurysms, while emphasizing the importance of preserving collateral blood flow.

Updates on Adult Transcranial Doppler, Gray-Scale, and Contrast-enhanced US Techniques

Mar 12, 2026

The authors aim to provide a comprehensive update on the advancements and clinical applications of transcranial ultrasound techniques, particularly focusing on transcranial Doppler imaging (TCDi) and its integration with gray-scale and contrast-enhanced ultrasound. They highlight the importance of these techniques in improving diagnostic confidence and expanding the scope of neuroimaging in adult patients, while advocating for greater clinical adoption despite their underutilization. The article emphasizes evidence-based indications and practical applications to enhance awareness of transcranial ultrasound's value in contemporary neuroimaging.

Update on Management of Incidental Findings Seen on Imaging Studies of the Abdomen and Pelvis

Mar 5, 2026

The authors aim to update the management guidelines for incidental findings (IFs) observed in abdominal and pelvic imaging studies, addressing the clinical significance of these findings, which can range from benign to potentially malignant. They review recent literature that either supports or contradicts existing guidelines from the American College of Radiology, while also highlighting common IFs that have not been previously discussed in official white papers. This update seeks to mitigate unnecessary follow-up procedures and the associated burdens on patients and the healthcare system.

US-guided Perineural Injections of the Upper Extremity from the Arm to the Wrist

Mar 5, 2026

The authors investigate the efficacy and safety of ultrasound (US)-guided perineural injections for diagnosing and treating upper extremity neuropathies. They emphasize the importance of precise nerve localization and detailed anatomical knowledge in performing these injections, which can provide immediate pain relief and assist in confirming specific neuropathies prior to surgical intervention. The paper includes a review of relevant nerve anatomy, injection techniques, and case examples to illustrate best practices.

Cowden Syndrome: Imaging Review and Cancer Surveillance

Feb 26, 2026

This article reviews Cowden syndrome (CS), a genetic disorder linked to mutations in the PTEN gene, which predisposes individuals to various malignancies and hamartomatous lesions. The authors aim to outline the clinical manifestations, imaging features, and updated cancer surveillance recommendations for early diagnosis and management of patients with CS. They emphasize the importance of comprehensive evaluation and specific imaging strategies to monitor the increased cancer risk associated with this syndrome.

Quantitative Dual-Energy CT in Abdominal Imaging: Technical Considerations and Emerging Clinical Applications

Feb 26, 2026

The authors investigate the advancements and challenges of dual-energy CT (DECT) in abdominal imaging, aiming to enhance diagnostic capabilities through improved material characterization and quantitative analysis. They provide an overview of DECT principles, current clinical applications, and potential future uses, including the integration of artificial intelligence and imaging biomarkers. The paper highlights the need for overcoming implementation barriers to fully realize DECT's benefits in clinical practice.
