MS lesions can be detected by simple subtraction of MRI scans taken before and after the injection of GdDTPA contrast agent. However, this highlights global changes in the post-injection scan in addition to the lesions. We introduce a new non-parametric subtraction measure, analogous to standard...
This is very promising, but work remains to be done to confirm or exclude lesions of common MS mimics, such as acute disseminate encephalomyelitis, as venocentric. A number of technical challenges must be addressed before the introduction of this technique as a complementary tool in current ...
GBCD is administered through a vein during the MRI, causing active MS lesions to "light up." After an MRI, most GBCD is removed from the body in urine, but trace amounts may stay in the body and accumulate over time in people who have MRI scans with GBCD frequently.1 This article ...
Currently, patients with clinically isolated syn- drome (CIS) and brain lesions on MRI sugges- tive of multiple sclerosis (MS), are offered a con- firmatory MRI scan after 6 months. Researchers in Italy have found, however, that conversion to a diagnosis of MS based on MRI can be made...
scan (which had been arbitrarily determined), thereby facilitating management of patients; and the acceptance of the concomitant presence of gadolinium-enhancing and gadolinium-nonenhancing lesions as evidence for DIT, which allows very early diagnosis in some patients who undergo a single MRI ...
Whether cysts and lesions in this area are cancerous or benign Prostate MRI This is used to see whether there's cancer in your prostate and if it's spreading, as well as to evaluate other issues like an enlarged prostate. fMRI A special kind of MRI called a functional MRI (fMRI) maps...
These findings are consistent with substantial focal inflammatory demyelination early on, with neurodegeneration in the deep grey matter being secondary to lesion accumulation8,9, related to the degeneration of tracts transected in MS lesions or concomitant inflammatory processes in the white matter and ...
C HE staining showed low cell density lesions and loose arrangement of cells accompanied by dense fibrous background. The cell morphology is consistent, and part of the cytoplasm is transparent. (× 200). D, E DWI and ADC images with a b value of 1000 mm2/s showed the tumor was ...
In clinical practice, diagnosis of suspected carious lesions is verified by using conventional dental radiography (DR), including panoramic radiography (OPT), bitewing imaging, and dental X-ray. The aim of this study was to evaluate the use of magnetic resonance imaging (MRI) for caries visualiza...
To investigate the 3.0-Tesla (3 T) magnetic resonance imaging (MRI) characteristics of primary adnexal lesions for discriminating benign from malignant lesions. One hundred thirty-nine patients with pathologically proven primary adnexal masses referred f
