The aim of this study was to evaluate critically available data on … 2015-03-01 Bosniak Classification of Renal Cystic Disease. The Bosniak classification was described in 1986. This classification helps the radiologist to categorize each cystic renal mass as "nonsurgical" (ie, benign in category 1 and 2) or as "surgical" (ie, requiring surgery in category 3 and 4). The Bosniak classification was originally developed to classify renal cysts based on CT findings, but MRI and CEUS can also be used [12,[22][23] [24] as the latter techniques show even higher The Bosniak classification of cystic renal masses (CRMs) has contributed substantially to the stratifi-cation of malignancy risk in the 3 decades since it was proposed (1). As a living system, refinements were made in 1993 and 2005 (version 2005) (2–4). With the cur-rent version of the Bosniak classification … 2019-06-18 The Bosniak classification for CT and MRI has been recently revised. 3 A Bosniak classification for CEUS has not been developed.

divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. The Bosniak classification system of renal cystic masses divides renal cystic masses into five categories based on imaging characteristics on contrast-enhanced CT. It is helpful in predicting a risk of malignancy and suggesting either follow up or treatment. The current Bosniak classification is primarily intended for masses that are completely characterized with a renal mass protocol CT or MRI examination (1, 2, 10, 73, 74). Because most renal masses are detected with examinations that are not designed to evaluate them completely, the Bosniak classification often cannot be applied (75).

Studien haben eine gute Vergleichbarkeit der CEUS mit der Bosniak-Klassifikation in der CT gezeigt. Es können jedoch kleinste KM-Mengen (und somit kleinste KM-aufnehmende Septen) dargestellt werden, was zu einer Einstufung in eine höhere Bosniak-Kategorie führen kann.

2016-06-07 · Twenty-nine lesions were classified as Bosniak I, II or II-F by CT and/or MRI and 13 as Bosniak III or IV, by one of the methods. The interobserver agreement for Bosniak classification for CT was 0.87 and 0.93 for MRI. Fifteen lesions had higher Bosniak categories on MRI, included six with change in management. Bosniak/kidney mass/kidney cyst classification Bosniak Classification and Recommendations (multiphasic CT/MR): Bosniak 1 – hairline-thin wall; no septa, calcifications, or solid components; water attenuation/signal intensity; no enhancement – no further imaging follow-up is required. Regarding the reliability of the Bosniak classification system, several studies have been reported between 1997 and the early 2000s (refer to Sect. 4.3). Among these, one major study by Curry et al.

Originally, it relied on computed tomography (CT) scan results and subsequently extended to magnetic resonance imaging (MRI). Renal cell carcinoma (RCC) surveillance was not enhanced in the past 20 years. Bosniak classifications depend on different morphological modifications in renal cysts such as septa 2020-12-07 Because of such a necessity, Bosniak, in 1986 , 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.
