“…12,14,19 Satake et al 19 have reported that the factors affecting breast movements apart the inner-lower quadrant were complex and unpredictable. In addition, Yoon et al 20 have showed that the range of lesion displacement between supine and prone positions differs according to the lesion's location and breast thickness and depth. This study reported that outer locations showed greater measurement discrepancies than inner locations.…”

PurposeThe aim of the study is to compare prone with supine breast magnetic resonance imaging (MRI) in terms of breast tumor location, size, shape, and tumor-to-tumor distances in multifocal lesions to improve image-based guidance for surgical planning.MethodsA retrospective analysis was conducted on 75 lesions in 50 patients with pathologically proven breast cancer who underwent MRI in prone and supine positions between December 2019 and December 2020. The transverse, anteroposterior, and craniocaudal dimensions (in millimeters) of the tumor in the x-, y-, and z-axes were measured. Distances from the center of the tumor to the chest wall and the adjacent skin were measured on transverse and reformatted sagittal images. In cases where multifocal lesions were present, the transverse, anteroposterior, and craniocaudal distances between the tumor centers in the x-, y-, and z-axes were measured. Differences between measurements in supine and prone MRI were evaluated with the Mann-Whitney U and the Wilcoxon tests. P values of less than 0.05 were considered to indicate a statistically significant difference.ResultsThe analysis revealed 31 MRIs with 1 and 20 with multifocal lesions. The x-axis dimension of the lesions in prone and supine positions did not significantly differ (P = 0.198) between the 2 positions. A significant difference in the y- and z-axes dimensions was observed between the prone and supine position (P = 0.00 for both). The distance from the tumor to the chest wall and the adjacent skin showed significant difference (P = 0.00 for both). For multifocal lesions, the distance between the lesions showed a significant difference on the y-axis (P = 0.00).ConclusionsThis study showed a significant difference in the tumor size, location, and tumor-to-tumor distances due to change of patient position, from the standard prone MRI to the supine position in the operating room, resulting in distortion, spatial repositioning, and convergence of the lesions. Supine MRI may be considered in providing a less extensive surgery.

“…First, due to gravitational breast tissue deformation in the prone position, diagnosis and treatment are complicated since the breast shape differs considerably from the posture in supine ultrasound (US) or surgery, 18,19 whereas acquisition in the supine position facilitates image fusion [20][21][22] and tumor localization during US-guided biopsy, surgery, or radiation therapy. 23 In addition, the prone posture is uncomfortable for the patient, and the lack of physical support of the hanging breasts may lead to motion artifacts, which compromise image quality.…”

Background: Breast cancer, the most common malignant cancer in women worldwide, is typically diagnosed by x-ray mammography, which is an unpleasant procedure, has low sensitivity in women with dense breasts, and involves ionizing radiation. Breast magnetic resonance imaging (MRI) is the most sensitive imaging modality and works without ionizing radiation, but is currently constrained to the prone imaging position due to suboptimal hardware, therefore hampering the clinical workflow. Objectives: The aim of this work is to improve image quality in breast MRI, to simplify the clinical workflow, shorten measurement time, and achieve consistency in breast shape with other procedures such as ultrasound, surgery, and radiation therapy. Materials and Methods: To this end, we propose "panoramic breast MRI"-an approach combining a wearable radiofrequency coil for 3 T breast MRI (the "BraCoil"), acquisition in the supine position, and a panoramic visualization of the images. We demonstrate the potential of panoramic breast MRI in a pilot study on 12 healthy volunteers and 1 patient, and compare it to the state of the art. Results: With the BraCoil, we demonstrate up to 3-fold signal-to-noise ratio compared with clinical standard coils and acceleration factors up to 6 Â 4. Panoramic visualization of supine breast images reduces the number of slices to be viewed by a factor of 2-4. Conclusions: Panoramic breast MRI allows for high-quality diagnostic imaging and facilitated correlation to other diagnostic and interventional procedures. The developed wearable radiofrequency coil in combination with dedicated image processing has the potential to improve patient comfort while enabling more time-efficient breast MRI compared with clinical coils.
