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”

Extensive Calcifications on Brain MRI in a case of Hypoparathyroidism


16-year old presented with seizures of five years duration. Seizures were of generalized tonic-clonic type. He was earlier diagnosed to have hypoparathyroidism on the basis of low serum calcium and low PTH levels in blood. MRI brain showed bilateral symmetrical calcifications involving caudate nucleus, globus pallidus, thalamus and dentate nucleus of cerebellum. Calcifications were hyperintenseContinue reading “Extensive Calcifications on Brain MRI in a case of Hypoparathyroidism”

Subependymal Calcification Demonstrated on SWI MRI in a Case of Tuberous Sclerosis


Tuberous sclerosis is a multi-systemic genetic disease, which predominantly manifests with seizures and cutaneous manifestations (such as adenoma sebaceum). Abnormalities on brain scan include cortical tubers, subependymal nodules (sually calcified) and subependymal giant cell astrocytoma (SEGA). MRI is usually preferred over CT scan as tubers and SEGAs are better appreciated on MRI as compared toContinue reading “Subependymal Calcification Demonstrated on SWI MRI in a Case of Tuberous Sclerosis”
