The normal appearance of CT myelograms.

Purpose: CT myelography has been used since 1976 to diagnose neural compression in the axial skeleton. With the advent of routine MRI, its role in accurately diagnosing neural compression has been questioned as its normal appearances are not defined in the study. In this study, we examine a series of CT myelograms to define the normal appearances of the neural elements of the spine.

The comparative hemodynamic efficacy of lower limb muscles using transcutaneous electrical stimulation.

Background: Circulation in the limbs can be augmented using transcutaneous electrical stimulation devices. The optimum muscle stimulation sites for enhancement of vascular hemodynamic parameters have not been identified.

Methods: Seven suitable anatomic sites were identified within the right leg.
