Abstract

We report the SPECT, CT and CW Doppler findings in a series of 117 patients with cerebral ischemic lesions and correlate them with the clinical finding SPECT-PAO proved to be more sensitive in localizing focal lesions than CT which in 50% of the cases was normal or yielded an image of cerebral atrophy. In the latter cases CW Doppler ultrasound on the supraaortic trunks showed changes, circumscribed or diffuse. On the CW Doppler and SPECT evidence we consier that the CT image of cerebral atrophy may denote an alteration of the cerebral blood flow and metabolism and should be assessed in this light in the diagnosis and prognosis of cerebral ischemic lesions.

Sommario

Gli autori presentano i dati SPECT, TC, e CW DOPPLER in una casistica di 117 pazienti affetti da lesioni ischemiche cerebrali e correlano i risultati di tali indagini con il quadro clinico. Evidenziano inoltre la sensibilità dell'esame SPECT-PAO per la localizzazione di lesioni focali nei confronti della TC che nel 50% dei casi risulta normale o evidenzia un quadro di atrofia cerebrale. In questi sessi casi l'esame CW Doppler, eseguito a livello dei tronchi sopraortici, dimostra alterazioni cricoscritte o diffuse.

Sulla base dei dati forniti dalla CW Doppler e dalla SPET gli autori ritengono pertanto che il reperto TC di atrofia cerebrale possa essere espressione di una alterazione della perfusione e del metabolismo cerebrale quindi debba essere rivalutato per la diagnosi e la prognosi di pazienti affetti da lesioni ischemiche cerebrale li.
