Figure 4. Representative 3D MDCT images of the L3 vertebra obtained from a 71-year-old man after 24 dynamic CT scans and seven transarterial chemoembolization (TACE) procedures for hepatocellular carcinomas.
An axial CT image of the liver shows segmental low density areas in the S5 and S7 areas due to previous TACE procedures(a). The 3D image shows sparse trabecular bones (b) compared to those of the patient in Figure 3. Tissue bone mineral density (36.2 mg/cm3) is lower than the mean value of control subjects. The image is cut in half along the longitudinal midline.
