case_images: Patient 1. The left anterior oblique view images at end diastole (a) and end systole (b) show a small round photopenic defect overlying the mid-septum. A round focus of absent counts in the region of the septum, measuring approximately 1.5 cm, was also identified on the phase (c) and amplitude (d) parametric images.

case_images: The left anterior oblique (LAO) view images (Figure 1a,b) revealed a small round photopenic defect overlying the septum, which did not change location on the dynamic images. A round focus of absent counts in the region of the septum, measuring approximately 1.5 cm, was also identified on the phase and amplitude parametric images (Figure 1c,d).
case_images: Patient 1. A chest radiograph revealed a dense ring-like object in the region of the left breast, which was the metallic injection port of the left breast tissue expander.

case_images: A chest radiograph revealed a dense ring-like object in the region of the left breast (Figure 2). 1 month earlier, the patient had a skin-sparing left mastectomy with immediate reconstruction.

case_images: Patient 2. The left anterior oblique view images at end diastole (a) and end systole (b) show a small round photopenic defect overlying the upper part of the septum. There was also a semicircular focus of absent counts in the upper part of the septum extending into the left ventricle on the phase (c) and amplitude (d) parametric images.

case_images: MAGNA-SITE integrated injection port in the tissue expander. MUGA scans performed at 2, 5 and 8 months after expander insertion showed a photopenic defect overlying the upper part of the septum (Figure 3a,b). There was also a semicircular focus of absent counts in the upper part of the septum extending into the left ventricle on the phase and amplitude parametric images (Figure 3c,d).
case_images: Patient 2. A chest radiograph revealed two dense ring-like objects in the regions of the breasts, which were the metallic injection ports of the breast tissue expanders.

case_images: A chest radiograph revealed two dense ring-like objects in the breast regions (Figure 4), which were the tissue expander metallic injection ports.
