Precision Meets Pain Relief: Image-guided Nerve Blocks in Interventional Radiology

May 7, 2026

The authors explore the role of image-guided nerve blocks in interventional radiology as a means to enhance pain management while reducing opioid use. They discuss the mechanisms, techniques, and safety considerations of various nerve blocks, as well as their clinical applications and emerging uses in oncologic and palliative care. The paper serves as a comprehensive resource for interventional radiologists aiming to effectively incorporate nerve block techniques into their practice to improve patient outcomes.

Postoperative Imaging of Peripheral Nerves: Review of Surgical Techniques, Expected Findings, and Complications

May 7, 2026

The authors aim to provide a comprehensive review of surgical techniques for peripheral nerve injuries, detailing expected postoperative imaging findings and potential complications. They emphasize the importance of accurate imaging evaluation using high-frequency ultrasound and MRI to differentiate normal postoperative changes from complications, thereby aiding in clinical decision-making and optimizing patient care.

Cardiac MRI in Depiction of Myocardial Edema: A Comprehensive Review

May 7, 2026

The authors review the diagnostic utility of cardiac MRI in identifying and characterizing myocardial edema, which is crucial for understanding various cardiovascular conditions. They aim to address the challenges in detecting myocardial edema, discuss imaging strategies, and highlight the importance of integrating clinical context with imaging findings. Through case examples and literature review, the paper provides a systematic framework for evaluating myocardial edema in clinical practice.

Multimodality Evaluation of Regional Breast Lymph Nodes: Impact of Expected Changes in the Upcoming BI-RADS Sixth Edition

Apr 30, 2026

The authors aim to evaluate the anticipated changes in the upcoming sixth edition of the Breast Imaging Reporting and Data System (BI-RADS) regarding the assessment of regional breast lymph nodes, which is crucial for breast cancer staging and treatment. They discuss the introduction of a dedicated lymph node category and expanded guidance on lymph node characteristics across various imaging modalities, emphasizing the importance of accurate identification and intervention in lymph node evaluation. The paper also outlines a systematic approach to multimodality imaging and the role of histologic confirmation in the context of nodal staging.

PRECISE Version 2: Essential Tips for Prostate Cancer Monitoring Using MRI

Apr 30, 2026

The authors aim to enhance the monitoring of prostate cancer in patients undergoing active surveillance (AS) by updating the PRECISE criteria to version 2, which provides a structured reporting system for MRI evaluations. This version simplifies the assessment of longitudinal changes in MRI findings, focusing on lesion characteristics and the emergence of new lesions, thereby improving communication between radiologists and clinicians. The paper discusses the rationale for AS, the evolution of the PRECISE system, and practical applications through case examples.

Carcinoma of the Vulva

Apr 23, 2026

The authors aim to provide a comprehensive overview of vulvar cancer, focusing on its pathogenesis, routes of spread, and key imaging findings essential for diagnosis and staging. They emphasize the importance of various imaging modalities, such as MRI and PET/CT, in accurately diagnosing vulvar malignancies and informing treatment strategies. The review also highlights the clinical presentation and staging of this rare gynecologic cancer, predominantly affecting postmenopausal women.

MRI and US of Normal and Abnormal Digital Nerves

Apr 23, 2026

The authors aim to address the challenges and techniques involved in imaging normal and abnormal digital nerves, which are critical for sensory function in the fingers and toes. They provide a comprehensive review of the anatomical considerations, imaging protocols using high-frequency ultrasound and MRI, and common pathologies affecting these nerves, such as traumatic injuries and compressive neuropathies. This knowledge is intended to enhance clinical practice for the timely diagnosis and management of digital nerve lesions.

Lung Injury after Precision Radiotherapy: Temporal Evolution, Potential Pitfalls, and Complications

Apr 16, 2026

The authors investigate the temporal evolution and imaging characteristics of radiation-induced lung injury (RILI) following high-precision radiation therapy (HPRT) for lung cancer, aiming to differentiate RILI from tumor recurrence. They highlight the delayed onset and localized manifestations of RILI, which can complicate diagnosis and lead to misinterpretation of radiologic findings. Understanding these features is crucial for guiding follow-up care and improving patient outcomes.

Congenital Posterior Fossa Malformations: Imaging Patterns and Diagnostic Approach

Apr 16, 2026

The authors aim to enhance the understanding of congenital posterior fossa malformations by reviewing their embryology and categorizing them based on characteristic imaging patterns. They emphasize the importance of a pattern-based diagnostic approach to differentiate between various types of malformations, identify associated abnormalities, and improve patient management strategies. Ultimately, this framework assists radiologists in providing accurate diagnoses and guiding perinatal care.

Renal Oncocytic Neoplasms: Review of Classification Updates, Imaging, and Management

Apr 9, 2026

The authors aim to address the diagnostic challenges and management strategies for renal oncocytic neoplasms, which include a spectrum of tumors with varying behaviors and classifications. They highlight the difficulties in preoperative imaging that lead to high rates of unnecessary resections and discuss the potential of active surveillance and emerging imaging techniques to improve risk stratification and diagnosis. The review emphasizes the need for clearer distinctions between benign and malignant oncocytic tumors to optimize patient management.
