For obese subjects who do not completely fit on the scanner table, a hemi-scan protocol may be used.The subject should stand with weight distributed evenly on both feet and right arm bent 90°.Arm length is measured from the most superior point on the scapular spine to the tip of the olecranon process on the posterior aspect of the arm (see image below).The physical examination is tailored toward signs of malnutrition, including loss of subcutaneous fat, muscle-wasting, edema, and ascites, with severity graded from “none” to “severe.” The clinician then subjectively designates the overall nutritional status of the patient into one of 3 categories: "well nourished" (grade A), “mild-moderate malnutrition" (grade B), or "severe malnutrition" (grade C). The full assessment is divided into 4 groups: anthropometrics, general assessment, dietary assessment, and subjective assessment.Answers are assigned numerical values, which are added to a maximum score of 30.
