https://www.selleckchem.com/products/icg-001.html The spectrum of soft-tissue mass is varied, including neoplastic and nonneoplastic/inflammatory lesions. However, soft-tissue tumors have similar imaging findings and, therefore, the diagnosis of soft-tissue mass is challenging. Although careful assessment of the internal characteristics on imaging can often narrow the differential diagnoses, the differential diagnosis may be out of the question if identification of the soft-tissue mass origin is missed. The purpose of this article is to review the imaging findings and the essential anatomy to identify the primary site of the soft-tissue mass, and discuss the associated potential pitfalls. In order not to fall into a pitfall, recognition of characteristic imaging findings indicating the origin of the soft-tissue mass and anatomical knowledge of the normal tissue distribution are necessary. LEVEL OF EVIDENCE 5 TECHNICAL EFFICACY STAGE 3. The Work Support Profile (WSP) is a brief assessment instrument that enables staff supporting adults with disabilities to provide calibrated and individualized support for specific work tasks. This paper sought to examine the psychometric properties of WSP for people with disabilities. A pilot study was conducted with 239 sheltered workshop employees diagnosed mainly with intellectual disability to explore the structure of this assessment tool, and provide initial evidence of its psychometric properties. Subsequently, a larger-scale study captured a nationwide profile of 761 sheltered workshop employees with intellectual disability. Across both studies, factor analyses yielded a conceptually acceptable 5-factor structure with 33 items accounting for approximately 65% of the variance. Furthermore, the reliability, convergent and discriminant validity of WSP can be considered adequate. Results provide preliminary evidence that WSP is a psychometrically adequate tool for assessing the work support needs of adults with disabilities on giv
