Cerebral computed tomography (CT) scanning in patients with EC was reported to show basal ganglia calcification in 30% (15 of 50 cases) and mild cerebral atrophy in 8% (4 of 50 cases) (Halpern et al., 1991). AH three children in our study of infant-onset hypothyroidism who exhibited... 

The diagnostic work-up of a patient with suspected hepatic encephalopathy should include in any case a cerebral computed tomography. Subdural haematoma and also parenchymal bleeding are rare but significant complications of liver cirrhosis that must be ruled out before the diagnosis of HE is made.

Magnetic resonance imaging (MRI) or computed tomography (CT) is used to measure changes in brain size and volume and rule out stroke, brain tumor, or a cerebral edema.

Although magnetic resonance imaging is very useful (especially imaging of the temporal lobes), computed tomography typically is not helpful except in the initial evaluation for a brain tumor or cerebral bleeding. 

Scopolamine increases cerebral blood flow to lateral occipital cortex bilaterally and to the left orbitofrontal region (Grasby et al. 1995). Decreases are seen in the right thalamus, precuneus, and lateral premotor areas bilaterally. When normal subjects are chronically administered scopolamine, there is a 12% increase in cerebral blood flow on single photon emission computed tomography (SPECT), but a decrease in cerebral muscarinic binding (Sunderland et al. 1995). On the other hand, acute administration dose-dependently reduces cortical blood flow, which is maximal in frontal cortex (Gitelman and Prohovnik 1992 Prohovnik et al. 1997).

Furthermore, as Barnhart et al. (2004) pointed out, cerebral blood flow changes, evidenced by single proton emission computed tomography, as well as the pattern demonstrated in neuropsychological testing, support the hypothesis that the effect in question is a reversible front lobe syndrome rather than a residual component of mental illness.

Regional cerebral blood flow was assessed using single photon emission computed tomography (SPECT) and tracer HMPAO in 10 cocaine abusers within 72 hours of last cocaine use and then after 21 days of abstinence (145). Compared with controls, recent cocaine abusers...
