Offer Description
On mammography approximately 67% of tumors will be non-palpable and in these approximately 55%, radio-opaque breast calcifications are present, which can either be malignant or benign. Since the malignancy rate varies between 6 and 82% depending on the appearance on mammography, all women should undergo invasive stereotactic vacuum-assisted biopsy. However, because 70-80% of calcifications are histologically benign, most women will undergo unnecessary invasive diagnostic work-up, which is associated with psychological stress and reduced quality of life. Absence of contrast enhancement on a breast MRI can safely rule out malignancy in mammographically detected breast calcifications. However, breast MRI is relatively expensive, of limited availability, long scan time, not suitable (in case of metal implants or claustrophobia) and comfortable for all women. The recently developed dedicated breast CT is still under clinical investigation, and its potential use has not yet been established. A whole-body photon counting CT (PCCT) with high spatial resolution in combination with iodine contrast could be of added value in the assessment of malignant breast calcifications. Therefore, the purpose of this proposal is to investigate whether PCCT can safely rule out malignancy, avoid unnecessary invasive procedures, and psychological distress in women with calcifications on mammography. To achieve this goal the following work packages are proposed: i) development of a PCCT scan protocol for breast imaging: a phantom study, ii) optimization of PCCT scanprotocol and development of a PCCT reader assessment protocol for breast imaging: in-vitro study, iii) optimization of PCCT scanprotocol a reader assessment protocol for breast imaging: in-vivo study.
Job description
You will have the following main responsibilities and tasks:
- To develop a PCCT scan protocol for breast imaging based on literature;
- With the use of a breast phantom optimization of the PCCT protocol and development of new acquisition and reconstruction parameters for improvement of imaging quality and doses level;
- To analyze the PCCT scan protocol in breast specimens;
- To analyze calcifications in breast specimens on PCCT images and thereby developing a reader assessment protocol for breast calcifications on PCCT images;
- To identify and including patients for the analyzation of breast calcifications by using PCCT scan;
- To assess breast calcifications on PCCT images in comparison with mammography by using reader assessment protocol;
- To compare the outcome of PCCT images with the MRI images and to determine if PCCT can safely rule out malignancy;
- Cooperation with specialists on developing PCCT protocol and data analysis approaches of PCCT imaging;
- Writing of original research articles and reviews about the topic.
