Sup 6: Image – Images with the max number of nodes in the pelvic region.
Side by side comparison of the maximum number of nodes visualised in the pelvis on 18F-FDG PET/CT scans of the a) HIV-positive and b) HIV-negative participants.
a.) The maximum number of nodes visualised in the pelvis of HIV-positive participants was nine, in participants number 42 and number 114. Participant 114 in this image had a SUVmax of 15.13 in the pelvis, with four nodes visualised in the abdomen (one of which was the largest of all abdominal nodes in the HIV-positive participants: 7.6cm). One node was visualised in the thorax and no nodes were visualised in the head and neck region.
b.) The maximum number of pelvic nodes visualised in an HIV-negative participant was eight, seen in participant 122, with a SUVmax of 6.27 and a tumour SUV of 29.7. Participant 237 had the largest head and neck node (3.1cm) and the highest SUV in the neck (24.38) and the largest chain of nodes visualised in the thorax (>14cm) and the highest SUV in the thorax (21.77) out of all of the HIV-positive participants.
