To analyse diagnostic accuracy of MRI-DWI in detecting residual disease after cholesteatoma surgery and propose an optimum follow-up (FU) scheme.#A retrospective chart review of patients who had cholesteatoma surgery in a tertiary referral centre. 3.0 T non-echo planar diffusion weighted imaging was...
1A). The rate of fat replacement progression did not show any correlation with disease severity and duration, age, gender or genetical background. Fig. 1 T1-score and Atrophy-score progression. On the left, overall T1- (A) and Atrophy-score (B) variation at FU for each patient. In the...
Whole-body MRI, which can include multiparametric evaluation MRI of the prostate, can be performed in less than 1 hour. Whole-body MRI that outperforms BS ± x-ray and CT for discriminating subsets of patients with or without metastases25 appears to show similar diagnostic accuracy to 18F...
I had an excellent experience with Open MRI Rockville! I had been putting off doing a traditional MRI because of anxiety due to claustrophobia and was so happy to have discovered Washington Open MRI – and especially Technician Brian who made the process easy! From my initial phone consult with...
left on for the period of both the echoes, and is incompletely balanced to avoid dark banding artifacts otherwise associated with long TR fully balanced steady statesequences. Thecontrastof DESS is quite unique, true T2 or T1contrastweighting is not possible. There is a strong fluid signal but...
with MEG, and in fact, there are few examples of measurements made with the same equipment. CT requires X-ray exposure around the subject, which can introduce radiation risks and limit sensor placement. Furthermore, MRI can disrupt sensor operation due to the presence of strong static magnetic...
We aimed to evaluate whether white and gray matter microstructure changes observed with magnetic resonance imaging (MRI)-based diffusion tensor imaging (DTI) can be used to reflect the progression of chronic brain trauma. The MRI-DTI parameters, neuropat
These values can be quantified in each voxel by parametric fitting of several images with different contrast weighting. The resulting T1 and T2 maps enable automated plaque segmentation in its various constituents. Additionally, the MR signal can be made sensitive to water diffusion, which can be ...
Intravenous contrast is an important diagnostic tool in MRI for musculoskeletal infection. An association has been noted between gadolinium-based contrast agents and the development of nephrogenic systemic fibrosis in patients with end-stage chronic kidney disease, particularly in patients on dialysis.
