Quick Answer
Brain MRI is valuable for specific neurological concerns but is not routine for every headache, memory complaint, or tingling. Clinical findings guide imaging decisions.

Brain MRI (magnetic resonance imaging) is a powerful diagnostic tool that provides detailed images of brain structure. It is invaluable when specific neurological concerns arise, but it is not a routine screening test for every symptom. Clinical findings guide when imaging is warranted.
MRI is particularly useful for detecting structural abnormalities: tumours, stroke (especially early or in brainstem locations), multiple sclerosis plaques, infections, and structural causes of epilepsy. It provides superior soft-tissue contrast compared to CT, making it the preferred modality for most neurological conditions.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for stroke & tia.
When is MRI indicated? New neurological symptoms that suggest structural disease —— progressive weakness, new seizure in an adult, persistent visual or speech disturbance, or suspected multiple sclerosis. Stroke evaluation within the first hours can identify the type and location of infarction. Epilepsy investigation benefits from MRI to identify structural causes that may be surgically treatable.
When is MRI not needed? Simple tension-type headache without red flags does not require brain imaging. Typical migraine with a normal neurological examination does not warrant routine MRI. Age-related cognitive decline with a normal examination typically does not benefit from imaging. In these situations, clinical assessment is sufficient, and imaging would add cost without changing management.
Preparation involves screening for metal implants, pacemakers, or other contraindications. The scan takes 30 to 45 minutes and is generally well-tolerated. Results are interpreted by a specialist who correlates findings with clinical presentation.
Dr. Jitendra Prasad Yadav orders brain MRI selectively at Kathmandu Neurology Clinic (Durbar Marg, Opposite of Yak & Yeti Hotel) —— when the clinical question requires imaging and the result will influence management. NMC registration: 8029.

Note time of onset, call emergency services, do not give food/drink or leave the person alone.
TIA symptoms resolve, but it signals high short-term stroke risk. Urgent evaluation and prevention planning are essential.
Not necessarily; a single unprovoked seizure needs careful assessment before a diagnosis of epilepsy is made.
No; seizures vary widely. Some involve jerking (generalized or focal), while others present as staring spells, automatisms, or behavioral change with no apparent movement.
