1.31 ), which is a characteristically lucent space, and it contains the esophagus, lymph nodes, and posterior segments of the upper lobes. Increased opacity in the retrotracheal triangle in the lateral radiograph is abnormal, and although commonly resulting from an aberrant subclavian artery, other...
in 1965, weibel and fields distinguished between a straight course of the ica, an s- or c-shaped elongation with medial and/or lateral displacement of the elongated segment, a kinking of 1 or more segments, and coiling of the artery, which may also appear as a double loop. in their ...
First-pass perfusion imaging. First-pass perfusion image showing a decrease intake of contrast-medium in the perfusion segments of the circumflex coronary artery in a 9-year-old boy after the arterial switch operation. The finding were confirmed at invasive coronary angiography Full size image ...
The anterior spinal artery (ASA) is typically formed at the level of the foramen magnum by the confluence of descending branches of the intracranial segments of the vertebral arteries (above the posterior inferior cerebellar artery (PICA)). The descending branches from both vertebral arteries may jo...
spectral Doppler sampling of the intracranial ICAs, an A1 segment of the ACAs, M1 and proximal M2 segments of the MCAs, P1 or P2 segments of the PCA, the ophthalmic artery, the ICA siphon, the retromandibular ICA on the neck if indicated, the distal vertebral arteries, and the proximal ...
Cross-sectional imaging of the iliocaval territory identifies segments of occlusion and potential sites of venous compression lesions, as well as predicting the extent of stent reconstruction required. In acute ilio-femoral deep vein thrombosis (AIFDVT), pre-procedural imaging should define the extent...
(1) cases in which a catheter cannot be advanced into the target vessel because of vascular anatomical factors or because there is a considerable risk of coil migration, (2) the embolization of long vascular segments that extend from a drainage vein to a feeding artery due to vascular ...
CTA showed narrowing of the distal ends of bilateral carotid arteriae in 13 cases, in which, the left and right sides of the internal carotid arteriae mainly involved in 5 and 4 cases, respectively, vertebral-basilar artery stenosis in 5 cases, vertebral-basilar artery compensatory enlargement ...
