Computerized tomographic densitometry of the solitary pulmonary nodule using a nodule phantom.

The successful application of computerized tomographic density analysis for evaluating the solitary pulmonary nodule has previously been described and the technique has since been simplified by using a calcium-equivalent nodule reference phantom. Because published experience with this technique remains limited, the current research reports the Cleveland Clinic experience with the CIRS model III pulmonary nodule reference phantom. Without knowledge of the final diagnosis, the nodule phantom was used as the standard for categorizing 31 nodules in 29 patients as either benign or indeterminate. Secure diagnoses were obtained in all cases. Eleven nodules were called benign and ten proved so, whereas 20 nodules were classified as indeterminate. One lesion, an adenocarcinoma, was falsely called benign using this technique. The excellent density discrimination achieved with CT makes this a superior tool for analysis of the solitary pulmonary nodule, and the nodule reference phantom has greatly simplified the technique of CT densitometry. As demonstrated by this and prior studies, calcification is not a unique feature of the benign lesion and successful clinical application of this technique requires cautious interpretation of results.

Description of a food recording electronic device for use in dietary surveys.

A Food Recording Electronic Device has been developed for quantitative collection of dietary data in the home for a period of up to 3 weeks. The accumulated information on the weights and types of food, and time of consumption, is transferred to a host computer for calculation of the nutrient composition of the diet. Using this method the subject does not have to read the balance or keep a written diary, and the need for coding of records by a dietitian is eliminated.

Diet Surveys

Energy, protein and fat intake estimated using a food recording electronic device compared with a weighed diary.

Twenty nine subjects kept a weighed diet diary for 7 days. This was coded using both detailed food composition tables and food groups. During the 7 days a Food Recording Electronic Device (FRED) with food group keyboard labelling was also used. This group of motivated subjects had no difficulty in using the device, and the use of food groups was not a source of error. Some technical problems were identified which led to a significant systematic underestimation of energy, protein and fat determinations using the FRED, although the correlation coefficients between the two methods were high. The technical problems were of a type which can be eliminated in future models of the FRED.

Adolescent

An abbreviated food table using food groups for the calculation of energy, protein and fat intake.

A method of estimating the energy, protein and fat composition of diets is described, based on 84 food groups. Data from 3 dietary studies are used to compare intake calculated using the food groups and detailed food composition tables, with analyses of duplicate diets. For even small groups of people the mean differences and correlation coefficients between calculated and analysed results are similar for both methods of calculation. This approach could be used as a rapid coding method, or where skilled manpower is not available.
