A fully automated method for quantitative analysis of dynamic contrast-enhanced MRI data acquired with low and high field scanners, using spin echo and gradient echo sequences, depicting various joints is presented. The method incorporates efficient pre-processing techniques and a robust algorithm for ...
PURPOSE ECG synchronized phase-contrast cine-MRI (PC cine-MRI) is used for quantifying the intracranial condition such as intracranial compliance, intracranial volume change, cerebrospinal fluid flow (CSF) pressure, and applied to the diagnosis of a normal pressure hydrocephalus and Arnold-Chiari malfor...
To compare the usefulness of short inversion recovery (STIR) and T1-weighted, contrast-enhanced, fat-suppressed (T1W-CEFS) sequences for the evaluation of bone tumors. Eighteen patients with 19 bone tumors who underwent both STIR and T1W-CEFS imaging were evaluated. The tumors were categorized...
The objective of this study is to describe a new technical innovation which provides superior cortical and trabecular bone contrast on MRI.MethodsFRACTURE (fast field echo resembling a CT using restricted echo-spacing), a 3D gradient echo pulse sequence with restricted echo-spacing combined with an...
In cases with a high-grade glioma, showing enhancement on T1 contrast-weighted MRI, intraoperative fluorescence (5-aminolevulinic acid) is used to mark tumour cells during resection30, allowing consistent sampling of high tumour content samples and resulting in successful classification in 4 out of ...
with radioisotopes in the case of PET, iodine in the case of CT or paramagnetic metals in the case of MRI to visualize the heterogeneity of the tumor microenvironment. Recently, it was shown that natural unlabeled D-glucose can be used as a nontoxic biodegradable contrast agent in Chemical ...
Scanning time considerations have restricted routine use of 3D Fourier transform (3DFT)-encoded MRI to gradient-recalled echo sequences. We sought to combine isotropic 3DFT acquisition with fast spin-echo at a practical scan duration. This strategy offers versatile image contrast for musculoskeletal ...
false-negative rates were calculated for the optimal surgical adjunct given the patient’s diffuse glioma subtypes: FLAIR for IDH-mutant diffuse gliomas and contrast enhancement and 5-ALA was used for IDH-wild-type tumours. False-negative errors on the score 0 versus score 3 classification task ...
This difference in contrast to noise ratio remained for malignant lesions, but no significant difference was present for cysts and haemangiomas. We advise careful assessment of new sequences before conventional T2-weighted spin-echo is replaced by fast T2-weighted spin-echo in the detection of ...
