2022年1月2日 · In this article we describe the 2019 Bosniak classification of renal cystic lesions. The goals of the new 2019 Bosniak classification are to reduce interobserver variability, improve the precision rate of malignancy within each category and to increase specificity and thereby reducing the rate of unnecessary treatment of benign lesions.

2024年8月11日 · The proposed new version of Bosniak classification of cystic renal masses is the first major revision since the death of the American radiologist Morton Bosniak (1929-2016), who died three years earlier.

2024年8月21日 · The Bosniak classification system of renal cystic masses, now known as Bosniak v2005, divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT, and helps predict a risk of …

2025年1月13日 · The frequency of renal cysts increases with age, and they are present in approximately ~40% of all individuals receiving a CT scan 3. Incidental renal cysts are present in ~0.2% of pediatric patients 4. Radiographic features Ultrasound. Simple renal cysts are commonly defined as having all of the following features:

2019年6月18日 · The updated Bosniak classification of cystic renal masses (Bosniak Classification, version 2019) aims to improve the original classification’s ability to predict the likelihood of malignancy in a cystic renal mass.

2023年3月4日 · Because of such a necessity, Bosniak, in 1986 (4), developed a classification system based on computed tomography (CT) imaging criteria allowing for the analysis of renal cysts' contour and contents, presence of septations and/or calcifications, and enhancement after contrast agent injection.

2022年8月20日 · Contrast-enhanced ultrasound (CEUS) is promising to overcome this deficit but warrants standardization. This study addresses the benefits of a combined CEUS and CT/MRI evaluation of renal cysts. The study provides a realistic account of kidney tumor boards' intricacies in trying to validate renal cysts. 247 patients were examined over 8 years.

2021年4月16日 · The revised classification of cystic renal masses, known as Bosniak Classification, version 2019, was intended to improve the ability of radiologists and other physicians to differentiate benign from malignant cystic renal masses.

2023年10月31日 · According to the 2019 update of the Bosniak classification, the main imaging features that need to be evaluated to achieve a correct characterization of renal cystic masses include the thickness of walls and septa, the number of septa, the appearance of walls and septa, the attenuation/intensity on non-contrast CT/MRI and the presence of ...

The EFSUMB Position Paper on a Bosniak-adapted renal cyst classification based on CEUS recommends advanced ultrasound experience, according to EFSUMB competency level 2, as a prerequisite for performing CEUS examinations of the kidneys .
