    Notizen: Abstract Mammography and accurate microcalcification detection require very good spatial resolution. We have compared the diagnostic capabilities of reduced-exposure, third-generation, 5 cycles/mm computed radiography (CR) phosphor plates with conventional screen-film in 67 patients. No difference in diagnostic accuracy was detected. The digital characteristics of storage phosphor plates erabled us to study the relationship between contrast and spatial resolution. We developed a computer program to identify a single 100 μm pixel in a digital image and assign various gray levels to that pixel. Using this model, we determined that, for our 5 cycles/mm CR system, the imaged contrast of a 100 μm object was 62% of the original contrast. Current 5 cycles/mm phosphor plate systems cannot adequately detect microcalcifications that approximate 100 μm or smaller unless a magnification technique is used.

    Notizen: Abstract Assessing the long-term behavioral effects of sex offender treatment was undertaken by interviewing a total of 70 sex offenders. A structured interview process was used, along with pre- and post-testing for 5 time periods. Participants were asked to indicate their ability and confidence on 10 variables regarding risks of offending at 6 months, 1, 2, 3, and 4 years post-treatment. Trends indicate overall improvement and increased ability to maintain a new life-style free from offending behavior. These self-report data corresponded with results on the Tennessee Self Concept Scale, the BEM sex Role Inventory and the Derogatis Sexual Functioning Inventory. Four years after treatment, participants reported total confidence for not reoffending. They stated that they felt they had control over their sexual misconduct even though their sexual urges still remained a problem. Most felt less need to use their maintenance plan, although they used it when needed.

    Notizen: Abstract In an attempt to assess the effectiveness of a community-based sex offender treatment program, questionnaires were sent to 153 former male patients. It was expected that only the 110 patients who had completed or almost completed treatment would return questionnaires. A total of 61 patients returned the form. Program components utilized during treatment were analyzed and data on current offending urges were obtained. The patterns and characteristics patients had before and after treatment were analyzed for behavioral changes as well as recidivism. Recidivism data were self-report as well as computer checked in cooperation with the state law enforcement agency. Retrospective review shows clinical improvement by most patients in all areas of treatment. Recidivism rate for the entire population (n=153) was 3.7%. This preliminary study indicates that a significant number of treatment modalities are effective for outpatient sex offenders.
