From: Feasibility of CT quantification of intratumoural 166Ho-microspheres
Computed tomography (CT) images of patient number 1. Axial, sagittal, and three-dimensional CT reconstructions of patient number 1 with a large necrotic tumour on the left neck side. During injection, the holmium microspheres were clearly visible on ultrasound as a cloud in the necrotic fluid and did precipitate after some minutes at the bottom of the tumour. The dorsal and caudal accumulation of 166Ho microspheres in the tumour is also well visible in the three images obtained in supine position (arrows in a, b, and c)
