The value of nonenhanced magnetic resonance imaging (MRI) in the grading of primary lower extremity lymphedema.

Objective: The International Society of Lymphology (ISL) proposed a grading standard for lymphedema in 2020 based on the percent increase in the volume of the affected limb compared to that of the healthy limb. However, this method is cumbersome and time-consuming to measure and calculate, and a standardized formula across different institutions is not available. Therefore, the aim of this study was to investigate the value of nonenhanced MRI for grading primary lower extremity lymphedema (PLEL).

Objectives: While lumbar puncture (LP) remains gold standard for assessing intracranial pressure (ICP), LP can be difficult to perform and lead to complications. Noninvasive correlations for elevated ICP via ocular ultrasound (OUS) have shown mixed results. The primary objective of this study is to identify the frequency and test characteristics of the crescent sign on OUS for elevated ICP.

Purpose: This study aims to assess the diagnostic efficacy of conventional ultrasound (CUS) and contrast-enhanced ultrasound (CEUS) in detecting fat-poor angiomyolipomas(AML) with dimensions less than 5 cm. Additionally, the study seeks to identify independent indicators for predicting the presence of fat-poor AML.
Methods: We conducted a retrospective analysis of patients diagnosed with renal AML and renal cell carcinoma, who were admitted and underwent surgery at Fujian Provincial Hospital from January 2013 to October 2023.

Background: The value of magnetic resonance imaging (MRI) presentation of primary lower extremity lymphedema in assessing the severity of lower extremity lymphedema is uncertain. The purpose of this study was to assess the role of MRI presentation in staging primary lower extremity lymphedema.
Methods: We enrolled 228 patients with clinically diagnosed primary lower limb lymphoedema from January 2018 to December 2019 in our hospital retrospectively.
