The purpose of our educational exhibit is: To present our technique of multidetector computed tomography angiography (MDCTA) in a series of patients with peripheral artery disease (PAD),
using the “bolus test” (BT) technique To optimize the acquisition delay obtaining homogeneous arterial contrast enhancement (CE),
without venous or parenchymal contamination To describe normal arterious vessels anatomy of lower limb in MDCTA images To show the findings obtained in patients with PAD
Digital subtraction angiography (DSA) is the standard of care in the evaluation in patients with PAD; however it is an invasive procedure with a non-negligible risk of complications [Hessel]. For this reason non-invasive techniques such as MDCTA are increasingly used for the assessment of peripheral artery anatomy and PAD.
The improvement of MDCT technology resulted in computed tomography scanner of 64 detector rows and more,
enabling thin collimation (0.625mm and smaller section thickness),...
Findings and procedure details
Procedure details Technique of multidetector computed tomography angiography (MDCTA) In our institution MDCTA are performed on a 64-slice scanner (LightSpeed VCT,
Patients are placed in a supine position with their legs and their feet held together without tapes. 1. First of all it is necessary to talk to the patient and ask which leg hurts more and/or sooner when at rest and/or walking. 2. Anteroposterior and lateral scout images are then obtained from the...
Peripheral arterial disease (PAD) is a world-wide problem affecting predominantly elderly patients [Aronow],
who has known,
have a progressive decrease in arterial blood flow [Masugata]. Because of fast scanning allowed by the current 64-slice and higher MDCT devices the exact assessment of the delay needed by the contrast media to reach the feet is critical to correctly plan and acquire MDCTA of PAD. Our MDCTA technique in PAD is feasible in routine and emergency allowing optimal assessment...
