    Abstract:
    A formal systematization of the set of procedures required in peripheral nerve morphometry has been implemented in a computer program, in an attempt to provide an easy-to-handle diagnostic tool in current neuropathological practice. The hardware is composed of an IBM-PC compatible computer and a graphic tablet. Programs are written in BASIC and run in computers compatible with the MS-DOS operating system. The flow of operative steps involved in the morphometric study is controlled by the software. Sequential measurements are also tested for congruence. Nerve fibre measurements are stored in pluri-dimensional matrices for subsequent statistical calculations, i.e. evaluation of size-frequency distribution of nerve fibres and correlation analysis between nerve fibre subcomponents. Stereological estimates of the parenchymal components are also derived. The increase in accuracy achieved using area instead of diameter measurements is stressed. Compared to "dedicated" machines such personal computer-assisted systems exhibit substantial advantages in terms of low cost and flexibility.
