The linear HDI systems have faster dynamics in the soft phase, as compared to the aromatic MDI ones, presumably owing to higher flexibility and better microphase separation.
IMT measurements were performed by a ATL (Advanced Technology Laboratories, Bothell, Washington 98021 USA), HDI 5000 system.
Most of the patients were reassessed personally (n = 23) at a mean age of 24.8 years using structured interviews covering dissociative disorders, other Axis I disorders and personality disorders (Heidelberg Dissociation Inventory HDI; Expert System for Diagnosing Mental Disorders, DIA-X; Structured Clinical Interview for DSM-IV, SCID-II).
All fetal sonographic weight estimations were carried out using ATL Ultramark 9 HDI ultrasound systems (Philips Medical Systems Ltd., Hamburg, Germany).> The anatomical landmarks of the ultrasound examination were the occipitofrontal and the biparietal diameter at its maximum.
A HDI 5000 sonography system with 5- to 8- and 4- to 6-MHz convex transducers (Philips, Ultrasound, Bothell, Wash).
Intima media thickness (IMT) of the common carotid artery was measured by an ATL HDI 3000 ultrasound system (Advanced Technology Laboratories, Bothell, WA) equipped with a 5-MHz linear array transducer, as previously described (19).
For the two-dimensional and Doppler ultrasound measurements, an ultrasound system (HDI 5000; Philips Medical Systems, Bothell, WA) with a linear-array transducer was used with a transmit frequency of 12 MHz.
We used a commercially available ultrasound system (HDI-5000; ATL-Phillips, Oceanside, CA, USA) equipped with a linear array transducer (CL15-7) operating at 15 MHz and providing frame rates up to 284 Hz.
A digital ultrasound system (ATL HDI 5000, Bothell, WA, USA) equipped with a broadband linear transducer (L12-5) was used for scanning the carotid artery in the longitudinal section.
