Aandoening
Our final goal is to treat patients with breast cancer using the MR-HIFU breast system. Before we can do this, we have to go through several steps. The first step is to assess the quality of images acquired on the MR-HIFU system.

Uitkomstmaten
Primaire uitkomstmaten
1. Image quality --> assessed by a score based on delineation of anatomical structures contrasts, SNR and artefacts of both MRI scans;<br>
2. Lesion descriptors of the BI-RADS lexicon in patients with a fibroadenoma --> described by shape and margin of the lesion and other findings on the MRI scans (e.g. edema, lymphadenopathy, skin thickening).
Achtergrond van het onderzoek
Breast conserving therapy is standard of care for patients with localized breast cancer. Due to technological advances, there is growing interest in less invasive treatment techniques. Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) is a new and non-invasive treatment modality. Philips Healthcare developed a dedicated MR-HIFU breast system for ablation of tumors in the breast. Since MR images acquired on this new system are used for therapy planning, treatment guidance and evaluation of therapy results, it is important to assess the image quality that can be achieved on the dedicated MR-HIFU breast system.
Doel van het onderzoek
This is a single center, prospective study to assess the quality of the MR images acquired on the MR-HIFU breast system in volunteers and patients with a fibroadenoma, by comparing images acquired on the MR-HIFU breast system with images acquired using comparable imaging techniques on a conventional 3-Tesla MRI scanner.
Onderzoeksopzet
Two MRI scans (each with a maximal duration of one hour) during one extra visit to the UMC Utrecht.
Onderzoeksproduct en/of interventie
Two MRI scans: One on the MR-HIFU breast system and one MRI scan in a conventional 3-Tesla MRI scanner.
