Occlusive arterial disease of abdominal aorta and lower extremities Comparison of helical CT angiography with transcatheter angiography

The purpose of this study was to evaluate helical CT angiography in the assessment of occlusive arterial disease of abdominal aorta and the lower extremities. Sixteen patients underwent both transcatheter angiography and helical CT. Helical CT was inconclusive in 6.2% of segments whereas angiography was inconclusive in 5%. The overall sensitivity of helical CT was 91% and specificity 93%. Segmental analysis found a sensitivity of 43% in infrapopliteal arteries, and a specificity of 86%.

THO-WP-4 Embolies pulmonaires non cruoriques : ce que le radiologue doit savoir

Objectifs Reconnaitre les differentes embolies pulmonaires non cruoriques. Connaitre les differentes modalites d’imagerie (radiographie de thorax, scintigraphie pulmonaire, tomodensitometrie multibarette, angiographie pulmonaire) et leurs resultats qui permettront de diagnostiquer une embolie pulmonaire non cruorique (tumorales microscopiques et macroscopiques, les septiques, gazeuses, graisseuses, corps etranger, ciment, mercure). Connaitre les elements qui permettront de les differencier des embolies pulmonaires cruoriques. Points cles A l’issue de ce poster, le lecteur doit etre capable de reconnaitre ces differentes entites en fonction du contexte et tableau clinique. Il doit connaitre leur aspect en imagerie qui permettra de les distinguer des embolies pulmonaires cruoriques.
