Because of this, “use of contrast has been dropping in the imaging of MS patients,” Zivadinov says. But MRI can still be used, without contrast, to diagnose and assess MS, he adds. T1-Weighted vs. T2-Weighted In an MRI without contrast, areas of active inflammation will show up bri...
With this noninvasive procedure also the evaluation ofblood flowand theflowof cerebrospinal fluid (CSF) is possible. DifferentMRAmethods, also withoutcontrast agentscan show a venous or arterial angiogram.MRIcan distinguish tumors, inflammatory lesions, and other pathologies from the normal brain anatomy...
The clinical use of MRI in patients with multiple sclerosis (MS) has advanced markedly over the past few years. Technical improvements and continuously emerging data from clinical trials and observational studies have contributed to the enhanced performance of this tool for achieving a prompt diagnosis...

INTERVENTIONS: We studied occipital cortex activation during visual stimulation by measuring occipital cortex perfusion with functional magnetic resonance imaging-blood oxygenation level-dependent contrast in 10 patients with migraine with aura and 2 patients with migraine without aura and 6 healthy subjects....
Patients in the mimics group were suffering from migraine with aura (n = 4), other types of headache (n = 3), seizures with concomitant postictual paresis (n = 12), dizziness (n = 7), syncopes (n = 8), hypertensive encephalopathy (n = 1), idiopathic paresis of the facial nerve...
Visualization of anterior disc displacement in temporomandibular disorders on contrast-enhanced magnetic resonance imaging: comparison with T2-weighted, proton density-weighted, and precontrast T1-weighted imaging[J]. Oral Surg Oral Med Oral Pathol Oral Radiol Endod, 2007,103(2):260-266. DOI: ...
chronic pain other than headaches, severe anxiety or depression, and psychiatric diseases; (3) without migraine preventive medication in the past 3 months; (4) absence of alcohol, nicotine, or other substance abuse; (5) no cerebral infarction, malacia or occupying lesions on the conventional MRI...
Hypothalamic structural integrity and temporal complexity of cortical information processing at rest in migraine without aura patients between attacks Article Open access 21 September 2021 Introduction Medication-overuse headache (MOH) is a common brain disorder in clinical practice with a prevalence of 0....
Migraine is considered as a risk factor for subclinical brain ischemic lesions, and right-to-left shunt (RLS) is more common among migraineurs. This cross-sectional study assessed the association of RLS with the increased prevalence of subclinical ischemic brain lesions in migraineurs. We enrolled ...
