    Two spiral tears of an intimal flap on VIE and MPR.

    No full text
    <p>VIE (A) shows two spiral tears of an intimal flap (narrow arrow) viewed from the true lumen; one of the spiral tears involves the innominate artery (wide narrow). MPR (B) cannot show the number and the spiral shape of the flap.</p

    Wavelike intimal flap on VIE and MPR.

    No full text
    <p>VIE (A) shows the entire wavelike intimal flap (arrow) viewed from the true lumen (A) and involvement into the edge of three branches. MPR (B) shows only a portion.</p

    Intimointimal intussusception on VIE and MPR.

    No full text
    <p>VIE (A) shows the true lumen (narrow arrow) of the intimointimal intussusception appearing as a “windsock” with a round entry tear (wide arrow) in the flap, thereby providing a more accurate configuration and spatial relationship than MPR (B) with a multiple-line type flap (the true lumen, wide arrow) located between the false lumen (narrow arrow).</p

    Involvement of a torn flap in the branches on VIE and MPR.

    No full text
    <p>VIE (A) shows complete involvement of the torn flap in three aortic branches and their spatial relationships (narrow arrow) with a more real and accurate visualization and location than MPR (B).</p

    Slit-shaped entry tear on VIE and MPR.

    No full text
    <p>VIE (A) shows the entire slit-shaped entry tear (arrow) on the aortic wall viewed from the true lumen. The MPR (B) displays only a portion.</p

    Aneurysm on VIE and MPR.

    No full text
    <p>VIE (A) shows a complete aneurysm (wide arrow) and a torn intimal flap (narrow arrow) derived from the edge of the aneurysm, thereby providing a more accurate shape and spatial relationships than MPR (B).</p
