Clinical Grading

Lymphoscintigraphy with combined qualitative and quantitative analysis is reported to be a more sensitive approach to diagnose lymphedema in comparison with the conventional clinical analysis. Our study seeks to evaluate the diagnostic performance of lower limb lymphoscintigraphy with amalgamation of qualitative and quantitative analysis by measuring the ilio-inguinal nodal uptake. This prospective observational study was comprised of 86 patients (172 limbs) diagnosed with lower limb lymphedema. After a thorough clinical grading of edema, radionuclide lymphoscintigraphy was performed as per a dedicated institutional protocol. Ilio-inguinal nodal quantification of tracer uptake was computed along with the visual study of the scans. Additionally, the corresponding mean nodal uptake percentage for each grade of lymphedema was assessed and a cut off nodal uptake percentage to differentiate between normal and abnormal limbs was defined. Although quantitative analysis with nodal uptake percentage provides objective criteria to diagnose lymphedema, it can only act as an adjunct to qualitative method without replacing it. Finally, standardization of procedure for quantitative lymphoscintigraphy is needed including the potential for combining both rate of clearance of tracer from injection site and nodal uptake for quantification.

Quantitative Results

Quantitative image analysis systems have been used for several years in research and quality control applications in various fields including metallurgy and medicine. The technique has been applied as an extension of subjective microscopy to problems requiring quantitative results and which are amenable to automatic methods of interpretation.Feature extraction. In the most general sense, a feature can be defined as a portion of the image which differs in some consistent way from the background. A feature may be characterized by the density difference between itself and the background, by an edge gradient, or by the spatial frequency content (texture) within its boundaries. The task of feature extraction includes recognition of features and encoding of the associated information for quantitative analysis.Quantitative Analysis. Quantitative analysis is the determination of one or more physical measurements of each feature. These measurements may be straightforward ones such as area, length, or perimeter, or more complex stereological measurements such as convex perimeter or Feret's diameter.

An important example of intracellular particles is encountered in silicosis where alveolar macrophages ingest inspired silica particles. The quantitation of the silica uptake by these cells may be a potentially useful method for monitoring silica exposure. Accurate quantitative analysis of ingested silica by phagocytic cells is difficult because the particles are frequently small, irregularly shaped and cannot be visualized within the cells. Semiquantitative methods which make use of particles of known size, shape and composition as calibration standards may be the most direct and simplest approach to undertake. The present paper describes an empirical method in which glass microspheres were used as a model to show how the ratio of the silicon Kα peak X-ray intensity from the microspheres to that of a bulk sample of the same composition correlated to the mass of the microsphere contained within the cell. Irregular shaped silica particles were also analyzed and a calibration curve was generated from these data.
