Renal
cell carcinoma invades the IVC and extends into the right
atrium
Sequence of images nicely shows a hypervascular birenal cell
carcinoma growing into the right renal vein, IVC and into
the right atrium. This is just a beautiful example of the
role of volume rendering and 3D mapping in staging renal tumors. |

| Pseudoaneurysm
of aortic root: 4D mapping demonstrates a pseudoaneurysm
arising off ascending aorta following aortic root repair.
The pseudoaneurysm compresses the SVC as well. |

| Compression
of trachea by right aortic arch with attempted double aortic
arch: Sequence of 4D images nicely defines the right aortic
arch with the aberrant left subclavian artery forming a ring.
The ring is not a complete ring as there is typically a fibrous
band, in this case, between the components of the left arch.
This is a beautiful example of such a case. |

MIP) demonstrates the normal right coronary artery and then
using volume rendering to also define the right coronary artery. |

and 4D display demonstrate a case of Marfan's Syndrome with
prior repair of the aorta above the valve. Now note the sinuses
of Valsalva are dilated due to compressive forces down by
the graft which has led to the need for a redo procedure. |

| Aortic
dissection with compression of the true lumen by false lumen.
The true lumen is compromised, particularly the descending
thoracic aorta, and some compromise of the abdominal aorta.
Note how nicely the true lumen gets compressed during systole.
This can result in ischemic changes. |

show the pseudoaneurysm and its position as well as relative
lack of motion. This is a beautiful case. |
