研究概览

简要总结

The study objective is to assess the performance of the MammoDetector Pro to correctly mark biopsy-proven breast cancers imaged on the Siemens Mammomat Novation FFDM system compared to conventional film-screen mammography.

详细描述

The study design is a controlled study. The study is designed to demonstrate that the performance of the MammoDetector™ Pro on biopsy-proven malignant cases obtained with the Siemens Mammomat NovationDR FFDM system is not inferior to its performance on biopsy-proven malignant cases obtained with conventional film-screen mammography (FSM). The overall sensitivity of the MammoDetector™ Pro with both imaging modalities will be compared. Furthermore, the study is designed to demonstrate that the false marks noted by the MammoDetector™ Pro on routine screening "Normal" cases obtained with the FFDM system is not inferior those marked by the software on routine screening "Normal" cases obtained with conventional film-screen mammography (FSM).

入选标准

  • Mammograms obtained from women 40 years of age and over;
  • Mammograms obtained from women only;
  • There are at least four standard views (right cranio-caudal [RCC], right medio-lateral oblique [RMLO], left cranio-caudal [LCC], left medio-lateral oblique [LMLO]) of the breast;
  • Informed consent is obtained.
  • Mammograms of biopsy-proven cancer cases will be considered eligible for inclusion in the study if they meet the following criteria:
  • Biopsy-proven malignant case that was assigned a BI-RADS category 4 or 5 with a suspicious lesion and the corresponding pathology report for the suspicious lesion is available.
  • Cases which have one or more lesion.
  • Routine screening "Normal" cases will be considered eligible for inclusion in the study if they meet the following criteria:
  • The case is a routine screening mammogram assigned a BI-RADS category 1 or 2 by a certified radiologist

排除标准

  • Cases are excluded from the study if they have any of the following conditions:
  • Mammographic needle projection or pre-biopsy markings are evident on the mammogram (these may cause false marks).
  • The mammograms include artifacts created by breast implant.
  • The mammograms are of poor quality (e.g., the digital image has very poor contrast);
  • Mammograms of biopsy-proven cancer cases will be excluded from the study if they have any of the following conditions:
  • Cases in which the lesion is only palpable or visible by another modality (e.g., Ultrasound, MRI).
  • The pathology is not related to a specific region. That is, there is more than one biopsy region and the pathology reports cannot be related to the appropriate mammographic lesion. For example, a mammogram with multiple lesions and multiple related pathology reports on the same date and it is not clear which pathology report belongs to each lesion.
  • The pathology report is more than three months after the FFDM or FSM mammogram.
  • The mammogram was performed for the purpose of planning cancer therapy (e.g., radiation) (BIRADS 6).
  • Cases in which the lesion is characterized as an architectural distortion. -
