Renal pseudotumors, which mimic tumors on imaging, pose diagnostic challenges that can lead to unnecessary interventions. Sensing ultrasound localization microscopy (sULM) is an advanced imaging technique that uses ultrasound imaging and microbubbles as sensors to visualize kidney functional units. This study aims to investigate whether sULM could differentiate between renal pseudotumors and tumors based on the presence of glomeruli.

Article Synopsis
  • The objective of the study was to update recommendations for managing kidney cancer based on recent literature from 2014 to 2024, focusing on diagnosis, treatment, and follow-up methods.
  • Key findings highlighted that kidney cancer linked to trichloroethylene exposure should be considered an occupational disease, and that contrast-enhanced CT scans are essential for diagnosis, while PET scans are not necessary.
  • The updated guidelines recommend specific classifications for tumors, advocate for less invasive strategies like biopsies to avoid unnecessary surgeries, and suggest various surgical and treatment options tailored to tumor size, patient age, and overall health.

Article Synopsis
  • Low-grade oncocytic tumor (LOT) is a rare type of kidney tumor that resembles other renal tumors, making it hard to diagnose; this study aimed to better understand its imaging characteristics.* -
  • Researchers analyzed preoperative imaging from 12 confirmed LOT cases using CT or MRI, finding common features such as well-defined borders and specific patterns of enhancement.* -
  • The study concludes that certain imaging features can suggest LOT, but further research is needed for validation, and a biopsy is recommended before treatment decisions.*

Introduction: The incidence of localized renal cell carcinoma (RCC) is on the rise among individuals aged 70 and older. While the gold standard for treatment remains surgical resection, some elderly and frail patients with comorbidities are not eligible for this procedure. In selected cases, percutaneous thermal ablation, such as cryotherapy, microwave and radiofrequency, offers less invasive options.

Article Synopsis
  • - This study conducts a meta-analysis to create a new grading system for liver steatosis using ultrasonography-based 2D-attenuation imaging (ATI), addressing the need for noninvasive tools in diagnosing liver disease.
  • - Eleven studies with 1374 patients revealed that ATI correlates strongly with histological and MRI-PDFF-confirmed steatosis, allowing for classification into four grades (S0 to S3) based on specific ATI measurements.
  • - The newly developed ATI grading system demonstrates high accuracy in determining liver steatosis, validated with independent patient cohorts and showing strong correlation with existing diagnostic methods.
