SWI (GRE) Sequences are the BEST to Detect Bleed on MRI Brain


It is extremely vital that we differentiate brain hemorrhage (bleeding) from brain infarcts, when patients present with clinical features of stroke. This is because patients with infarcts are eligible to receive thrombolytic treatment, to lyse the blood clots. On the other hand, thrombolytic treatment is contraindicated in patients with brain hemorrhage (bleed). Drugs used forContinue reading “SWI (GRE) Sequences are the BEST to Detect Bleed on MRI Brain”

55-year old gentleman, known diabetic and hypertensive presented with symptoms of right hemiplegia and aphasia of three hours duration. He was evaluated for possible thrombolytic treatment. CT brain done (3.5 hours after stroke symptom onset) showed a dense (also referred to as hyperdense) MCA sign (yellow arrow in the 1st image). Thrombosis of middle cerebralContinue reading “Hyperdense MCA sign in Acute Ischemic Stroke”
