Magnetic resonance angiography of the carotid arteries: comparison of unenhanced and contrast enhanced techniques

Abstract

SSFP-MRA, an unenhanced form of MRA, represents an alternative to CE-MRA, particularly in patients where administration of gadolinium for CE-MRA may be contraindicated. In contrast to other techniques, SSFP-MRA serves with not significant different results compared to standard CE-MRA.

Carotid artery stenting in difficult aortic arch anatomy with or without a new dedicated guiding catheter: preliminary experience

“…Neurological complications (2 TIAs and 2 minor strokes) and local The diagnostic pre-procedural study with CT angiography or MR angiography [43,44] is mandatory and allows determining which patients are best suited for CAS treatment with a dedicated guiding catheter, simplifying the procedure, reducing the risk of embolisation and increasing the success rate of CAS.…”

“…All patients underwent to CAS when an asymptomatic ICA stenosis >70 % or a symptomatic ICA stenosis >50 % was found by Doppler ultrasound and confirmed by CT angiography or MR angiography [43,44], according to current guidelines for carotid stenting [45,46].…”

Non-invasive ECG-triggered 2D TOF MR angiography of the pelvic and leg arteries in an open 1.0-tesla high-field MRI system in comparison to conventional DSA

“…U-King-Im et al, for instance, report overestimation of stenosis in the carotid bifurcation [24]. Kramer et al present data suggesting that non-contrast-enhanced MRA of the carotid artery is comparable in performance to contrast-enhanced MRA [9].…”

Optimal MRI Sequence for Identifying Occlusion Location in Acute Stroke: Which Value of Time-Resolved Contrast-Enhanced MRA?

“…The image diagnostic confidence index of both MRA sequences for SAA and intracranial arteries (Fig 1) was evaluated according to a modified diagnostic confidence index scale 27,30,35 …”
