About

Development of lympho-proliferation reticulation quantification using CT.

Full description

It is known that fibrosis of the subcutaneous soft tissue progresses over time in the lymph edema, and this change progresses to reticulation pattern. Authors will develop a digital subtraction technique for the extraction of lympho-proliferative reticulation using the Housfield unit of non-reticulation structure (bones, muscles, tendons, vessels, nerves) in the axial image of CT. Based on the medical records, authors will develop an early diagnosing tool by checking the correlation of the values derived the new technique with circumference, multi-frequency bio-electric impedance analysis, ISO sub-stage, and lymphascintigraphy, and qualify the cut-off values showing high sensitivity and specificity through the receiver operating characteristics (ROC) curve analyses.
