Rationale And Objectives: To improve the diagnostic recognition of papillary renal neoplasm with reverse polarity (PRNRP) through comprehensive analysis of computed tomography (CT) and magnetic resonance imaging (MRI) findings.
Materials And Methods: A retrospective multi-center study was conducted on patients with pathologically confirmed PRNRPs from 2019 to 2024, encompassing six institutions. Clinical and pathological data were meticulously documented.
Purpose: To explore the diagnostic characteristics of cystitis glandularis (CG) using magnetic resonance imaging (MRI).
Materials And Methods: A retrospective study was conducted on pathologically confirmed patients who underwent bladder MRI examination between January 2019 and November 2023. Image analysis was jointly conducted, with emphasis on lesion location, morphology, size, signal intensity, and pattern of enhancement, by two genitourinary radiologists with 22 and 15 years of experience, respectively.
Background: The von Hippel-Lindau (VHL) mutation is an important alteration in clear cell renal cell carcinoma (ccRCC); however, its imaging phenotype remains unclear.
Purpose: To investigate whether MRI features can reflect the VHL mutation status.
Study Type: Retrospective.
Article Synopsis
- The study evaluated the diagnostic performance of two versions of the Clear Cell Likelihood Score (ccLS), version 1.0 and version 2.0, in identifying five common subtypes of small renal masses (SRMs) in a retrospective analysis involving 797 patients with proven renal masses.
- Results indicated that ccLS v2.0 demonstrated superior diagnostic accuracy across multiple cancer subtypes compared to ccLS v1.0, with higher area under curve (AUC) values for clear cell renal cell carcinoma, papillary renal cell carcinoma, renal oncocytoma, and angiomyolipoma without visible fat.
- Additionally, the study assessed interobserver agreement and found that both versions of the ccLS showed differing levels
Background: Identification of non-diabetic renal disease (NDRD) in patients with type 2 diabetes mellitus (T2DM) may help tailor treatment. Intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) is a promising tool to evaluate renal function but its potential role in the clinical differentiation between diabetic nephropathy (DN) and NDRD remains unclear.
Purpose: To investigate the added role of IVIM-DWI in the differential diagnosis between DN and NDRD in patients with T2DM.
