It is surprising to read a paper with this title in 2006. It was shown in 1992 that the answer to the question posed in the title is “Yes,” if CT is used instead of MRI (Jobst et al., 1992). The latter paper showed that the medial temporal lobe shrinks with age in normal elderly but that in AD the thickness is usually much less than normal at any given age. Hence, such scans can aid in diagnosis and also in following the rate of progression (Jobst et al., 1994).
The assessment of the medial temporal lobe in AD was pioneered by Bill Jagust (Seab et al., 1988) and by Mony de Leon (de Leon et al., 1989) and its value has been widely accepted ever since. It is immaterial whether CT or MRI is used as a tool.
