Solitary bone tumor imaging reporting and data system (BTI-RADS): initial assessment of a systematic imaging evaluation and comprehensive reporting method

Imaging report and data system (RADS) for bone tumors: where do we stand and future directions

“…Since 2021, three different imaging RADS for focal bone lesions have been proposed, which underscores the interest in this approach but may also lead to confusion as there is no indication of which system is more efficient [2][3][4]. Also, probably none of these systems is sufficiently mature for clinical use.…”

“…The second system, the Osseous Tumor Reporting and Data System (OT-RADS) [2], by Chhabra et al, was a cross-sectional, retrospective, multi-reader study. A consensus agreement of five attending radiologists classified each type of bone tumor in different categories, using the BI-RADS as a template.…”

Klassifikationssystem für die Differenzierung von Knochentumoren

“…Die vorliegende französische Studie hat nun erstmals versucht, auf der Grundlage der bewährten viergliedrigen RADS-Stratifizierung eine Dignitätsklassifizierung für solitäre Knochentumoren vorzustellen und zu testen 3 .…”

Response to the letter to the editor in reference to OT-RADS

“…We apologize for this misunderstanding as your current letter clarifies this issue. Similarly, in the BTI-RADS [2], in addition to MRI both CT and radiographs were available for the readers. However, since the objective in this study was to evaluate the association of each imaging feature with malignancy, we aimed for the best accuracy possible and used CT data to avoid bias related to technical factors.…”
