Figures & Tables

Fig. 1.

CT image of the abdominal cavity in the arterial phase (acquisition approximately 20 seconds after intravenous injection of contrast agent) – clearly weaker enhancement of the cortex of the right part of the horseshoe kidney (45 vs 93 HU). The pelvicalyceal system of the right part of the kidney is widened (arrow)

Fig. 2.

CT image of the abdominal cavity in the parenchymal phase (acquisition approximately 50 seconds after intravenous injection of contrast agent) – weaker enhancement of the cortex of the right part of the horseshoe kidney persists (132 vs 164 HU). Visible dilatation of the right pelvis of the kidney (arrow)

3d reconstruction of the CT image of the abdominal cavity in the arterial phase – weaker enhancement of the cortex of the right part of the horseshoe kidney. A calculus in the left part of the kidney (arrow). 4 renal arteries supply the kidney

Fig. 4.

CT image of the abdominal cavity in the excretory phase (acquisition approximately 7 minutes after intravenous injection of contrast agent) – A 3d reconstruction shows lack of urine excretion from the right part of the kidney, left pelvicalyceal system enhances strongly. The non-enhancing region in the bladder corresponds to a tumour infiltrating the right ureter

Axial ultrasound image of the umbilical region. Visible dilatation of the right pelvis of the kidney (arrow). The location of the aorta was marked (A)

Fig. 6.

Axial CEUS image of the umbilical region – the enhancement curves from both parts of the kidney are similar in shape – slightly delayed inflow of contrast to the deeper right part of the kidney (blue vs red curve). The dilated renal pelvis (reference point – yellow curve) is not enhanced

Fig. 7.

An axial CEUS image of the umbilical region in the late phase – the enhancement curves from both parts of the kidney are similar in shape same as in the early stages – slightly delayed outflow of contrast to the deeper right part of the kidney (blue vs yellow curve)
