A Clinical Investigation to Confirm the Ability of MammoWave in Breast Lesions Detection

Официальное название

A Clinical Investigation (Multicentric, Single Arm, Prospective, Stratified) to Confirm the Ability of MammoWave (Microwave Mammogram) in Breast Lesions Detection

Обзор

This is a multicentric, single arm, prospective, stratified by breast density clinical investigation to confirm the ability of the microwave mammogram 'MammoWave' to detect breast lesions. MammoWave is a innovative medical device, class IIa marked CE, which uses microwaves instead of ionazing radiation (x-ray) for breast lesions. Specifically MammoWave employs a novel technique wich generates images by processing very low power (\<1mW) microwave. The MammoWave exam takes few minutes for breast and is performed with the patient lying in a confortable facing down position. MammoWave is safe to be used at any age, in any condition (pregnancy, specific illness and for unlimited number of times.

Подробное описание

The maximum number of participants to the clinical investigation will be 600 (for all the sites). The study will be composed of two phases: a preliminary phase to 'optimize the imaging algorithm for each apparatus installed at each centre', where 15 volunteers (in each centre) having breast with no lesions (NL) will be examined by MammoWave. In the second phase, the remaining people will be enrolled (BL will be 50% of total) and examined by MammoWave by the clinical investigator, and results will be compared with the effective diagnosis already obtained by standard clinical methods. BL includes malignant lesions (BC) and benign lesions, and may be palpable or non-palpable lesions. BL includes also isolated clustered microcalcifications.

The primary gol of the clinical study is to assess MammoWave's ability in BL detection.

The study will involve investigational sites in Italy, Germany and Spain.

Вмешательства

• Устройство Clinical investigation medical device class IIa marked CE
  Patients should perform MammoWave exam. A short visit should be performed and during this visit a qualitative differentiation would be performed between patients with high density breast, and patients with low density breast. After the patients are ready for MammoWave exam. The exam will composed of two phases: the acquisition and data processing. During the acquisition that sholud takes about 10 minutes the patients would be lying in a prone position, on a bed which is part of the MammoWave. Th

Критерии участия

Критерии включения

• Signed Informed consent Form
• Women
• Adult ≥ 18 years old
• Having a radiologist study output obtained using mammography within the last month. Such radiologist study output may be integrated with ultrasound and /or magnetic resonance imaging output if deemed necessary by the responsible investigator and when available. The radiological output will be integrated with histological one if deemed necessary by the responsible investigator and when available.
• Patients willing to comply with study protocol and recommendations
