Mar 28, 2025 · Brain MRI with SWI or GRE is recommended for the investigation and follow-up of cerebral cavernous malformations 14. For investigation of new symptoms suspicious for cerebral hemorrhage, CT can be used within 1 week of onset and MRI after 1 week 14 .

Sep 30, 2024 · But the real showstoppers in cavernoma detection are the gradient echo (GRE) and susceptibility-weighted imaging (SWI) sequences. These bad boys are exquisitely sensitive to the magnetic properties of blood, making cavernomas stand out like beacons in the night.

Dec 1, 2022 · The MRI protocol should include conventional T1- and T2-weighted imaging (WI), axial gradient recalled echo (GRE)/susceptibility-weighted imaging (SWI), and diffusion-weighted imaging (DWI).

In this article, our aim is to review the etiopathogenesis, clinical features, MRI strategies, and the MRI appearances of the disease, a brief differential diagnosis, and treatment options focusing on the giant CMs larger than 3 cm.

This MRI demonstrates widespread focal regions of susceptibility induced signal loss (best seen on susceptibility weighted imaging (SWI)) ranging in size from microscopic to a number of millimeters in diameter (remember that all T2* sensitive sequences result in a degree of blooming and thus grossly overestimate the actual size of the lesion).

Dec 15, 2014 · Objectives: We investigated the imaging features of Cavernous angioma (CA) lesions and the value of Susceptibility-weighted imaging (SWI) by comparing with T2*-weighted gradient echo (GRE) sequences in patients with familial CA disease.

Mar 26, 2019 · FCCM indicates familial cerebral cavernous malformation; GRE, gradient recalled echo; MRI, magnetic resonance imaging; and SWI, susceptibility-weighted imaging.

Jan 1, 2015 · The angiographic, computerized tomography (CT), and magnetic resonance imaging (MRI) findings were compared in 10 patients with a total of 16 pathologically verified cavernous angiomas.

The initial MRI showed a T1- and T2-hyperintense lesion in the left side of the pontine tegmentum, consistent with a recent haemorrhage within a cavernoma. SWI showed a network of small vessels representing an associated development venous anomaly; 6 months later, mild rim of oedema on FLAIR, blooming artefact and T1-hyperintensity had regressed.

Conventional MRI sequences (T1- and T2-weighted imaging) have been associated with the ability to identify clinically symptomatic CCM lesions with a specificity and sensitivity nearing 100% 42.
