To demonstrate the imaging aspects of the vascular thoracoabdominal emergencies,
such as aortic dissection,
arterial disruption and occlusive diseases,
pulmonary hypertension and others using high field Magnetic Resonance Imaging (MRI).
Angiography is used to evaluate the patency and integrity of blood vessels throughout the body,
but conventional catheter angiography is an invasive procedure that may also be time-consuming and labor-intensive.
But sometimes this method can be replaced by Magnetic Resonance Angiography (MRA) and Computed Tomographic Angiography (CTA) because those methods are a noninvasive assessment of the vasculature. MRA advantages include multiplanar acquisition,
lack of radiation,
the potential for...
Findings and procedure details
We conducted a review of the literature and retrospective analysis of around thirty cases of patients with vascular thoracoabdominal emergencies,
who were admitted to the emergency room and evaluated by MRI. Imaging characteristics will be demonstrated by anatomical sections,
and simplified pictorial schemes. NORMAL THORACOABDOMINAL AORTA NORMAL PULMONARY VASCULARIZATION PULMONARY EMBOLISM PULMONARY HYPERTENSION RELATED TO EMBOLISM FUSIFORM...
The aim of the authors was to demonstrate their experience in the use of MRI in the evaluation of vascular thoracoabdominal emergencies,
exposing different clinical conditions diagnosed with this method. Despitethe disadvantages above mentioned,
MRI may be very useful not only because some advantages (lack of radiation,
potential for diagnosis without contrast injection,
use of gadolinium) that can benefit many patients,
but due to its high accurateness,
testified with these many cases...
