BRAIN SCAN

 

brain (normal #1)

Clinical Indication: 80 year old white female with memory problems and depression - SPECT brain scan.

Dose: 25mCi Tc-99m-HMPAO given i.v.

Results: normal coritcal and cerebellar perfusion and metabolism with no evidence of Alzheimerís disease.

 


brain (normal#2)

Clinical Indication: head injury with personality change - SPECT brain scan.

Dose: 30mCi Tc-99m-DTPA given i.v.

Results: normal increased uptake in the cerebellar hemispheres bilaterally; normal distribution in frontal, temporal, occipital, and parietal lobes; basal ganglia normal.

 


brain (abnormal #1)

Clinical Indication: 55 year old white male status - post head injury - SPECT brain scan.

Dose: 30mCi Tc-99m-DTPA given i.v.

Results: linear area of decreased uptake in right temporal lobe region which could be consistent with brain contusion.

 


brain (abnormal #2)

Clinical indication: 52 year old white male w/ balance and memory difficulty - SPECT brain scan.

Dose: 30mCi Tc-99m-DTPA given i.v.

Results: decreased uptake of radiopharmaceutical in posterior frontal, parietal, and temporal areas on the left with sparing of the basal ganglia. (These findings are not characteristic of a common neurological disease and would unlikely represent Alzheimerís or supranuclear palsy.)

 


brain (abnormal #3)

Clinical Indication: 76 year old white female w/ increasing memory loss and depression - SPECT brain scan

Dose: 30mCi Tc-99m-HMPAO given i.v.

Results: basal ganglia normal; temporal, parietal, occipital lobes normal; cerebellum normal: decreased uptake in bilateral areas of frontal lobes consistent with depression - otherwise normal study.


brain (abnormal #4)

Clinical Indication: 55 year old male with recent onset of confusion and aggressive behavior - SPECT brain scan.

Dose: 27 mCi Tc-99m-DTPA given i.v.

Results: substantial activation of sensory motor strip, frontal poles, and the visual cortex; good perfusion of both temporal lobes and parietal lobes; mild assymetry in temporal lobes suggestive but not diagnostic of Alzheimerís disease; no frontal lobe abnormalities. (Given the severity of the patientís symptoms there may be an etiology other than Alzheimerís disease present.)

 


brain (abnormal #5)

Clinical Indication: 47 year old white female with head trauma and memory loss - SPECT brain scan.

Dose: 30mCi Tc-99m-HMPAO given i.v.

Results: small focal defect in the right parietal lobe; remainder of cerebral cortex shows normal perfusion in frontal, temporal, and occipital lobes and basal ganglia; decreased activity in right cerebellum which may indicate cerebellar infarction.
