Figure Lengend Snippet: CT volumetry performed for FLR volume in the evaluation for surgical resection of an intrahepatic cholangiocarcinoma. 3D images (Vitrea, Vital Images) (a) show the tumour (orange) and calculated tumour volume. Color overlays on contrast enhanced CT show exclusion of the mass (b) and the future liver remnant (c) during calculation. The liver remnant was 32%, but the patient had other comorbidities that precluded resection. 3D, three-dimensional; FLR, future liver remnant.

Figure Lengend Snippet: (a, b) During percutaneous microwave ablation, 3D rendering (NEUWAVE Ablation Confirmation Software, Ethicon) and non-contrast CT were obtained after placement of microwave ablation antennas (green, blue) into a HCC (red) in a cirrhotic liver demonstrating appropriate placement of the antennas bracketing the mass. (c, d) 3D and CT images with colour overlay show the ablation zone (delineated by the green circle) completely encompassing the lesion and providing an adequate circumferential margin. 3D, three-dimensional; HCC, hepatic cell carcinoma.

Figure Lengend Snippet: 3D colon map (V3D Colon, Viatronix) from CT colonography (a) showing the location of a sigmoid polyp (arrow, red dot), which measured 7.8 mm at initial screening (b). Polyp segmentation for volume measurement is shown on both the 3D and 2D (inset) views. Follow-up CT colonography 1 year later (c) shows that the polyp grew only 0.8 mm, but showed a 50% increase in volume (to 205 cm3). At same-day colonoscopy (inset), this lesion was removed and proven to be an advanced (tubulovillous) adenoma. 3D colon map (d) showing the location of three small polyps in the right colon (arrows, red dots). 3D images of the proximal transverse colon polyp initially (e) and at surveillance screening 16 months later (f) show an increase from 6.0 to 8.0 mm and increase in volume by 203%. Similar growth was seen with the cecal polyps. Once removed, the proximal transverse colon polyp was a tubular adenoma (non-advanced), and the two cecal polyps were advanced (tubulovillous adenomas).

Figure Lengend Snippet: Examples of normal and cirrhotic liver morphology on 3D (Liver Analysis application, IntelliSpace Portal, Philips) (a, d) and contrast enhanced CT (b, e) with segmentation color overlays (c, f) where segments I–III are yellow and segments IV–VIII are green. Normal relationship between segments are seen in the normal liver (a–c). The bottom row (d–f) demonstrates atrophy of segments IV–VIII and hypertrophy of segments I–III. (e) Note the marked hypertrophy of segment I (arrowheads). Reprinted, with permission, from reference.65 3D, three-dimensional.

Figure Lengend Snippet: Unenhanced CT (a–c) and corresponding 3D images (Ziosoft) (d–f) illustrate the asymmetric growth of a renal stone over 10 months. The linear stone diameter doubled (6.8 to 14.8 mm) between (a) and (b), and the corresponding volume of the stone increased by about 600% (49.6 to 200.3 mm3). (c) The stone continued to grow with a 39% increase in linear size (14.8 to 20.7 mm) and a 173% increase in volume (200.3 to547.6 mm3).

Figure Lengend Snippet: (a, b) 3D image (Advantage Workstation, GE Healthcare) and contrast enhanced CT of the abdomen demonstrate an infrarenal abdominal aortic aneurysm. (c–e) Follow endograft repair, 3D images obtained from unenhanced CT show an expected decrease in the volume of the aneurysm sac over time (231 to 173 cm3), excluding the presence of an endoleak and therefore i.v. contrast was not needed. 3D, three-dimensional.
