RESUMO
Compared the MCMI profiles of 25 veterans with a diagnosis of Posttraumatic Stress Disorder (PTSD) with those of 25 veterans carrying psychiatric disorders which typically cause problems in the differential diagnosis of PTSD. The PTSD group had higher elevations on nine of the 20 MCMI scales (all ps less than .05). Profiles were also significantly different in shape and scatter. A discriminant analysis accounted for 100% of the variance and correctly classified 88% of the patients. Resulting MCMI profiles appear to be consistent with DSM-III criteria for PTSD.

The extreme diffusibility of hydrogen, compared with xenon or krypton, may create serious artifacts when it is used to measure local blood flow with a tissue electrode. The errors are greatest when hydrogen is given by intra-arterial slug injection, and when the electrode is within 2mm of another tissue compartment, CSF, or air. These all appear to be a consequence of intercompartmental diffusion which can occur at rates of the same order of magnitude as clearance from the tissue by blood flow. No matter how small the electrode, the ultimate spatial resolution of the method appears to be about 2mm unless quantitative account is taken of diffusion. An important precaution in use of the method is to obtain homogeneous tissue saturation by prolonged inhalation administration.
