  • Abstract
  • Look Inside

A radar chart was prepared in an attempt to differentiate parotid tumors in patients who re-ceived ultrasonography during a 3-year period from 1984 to 1986.

The apparatus used was an electronic linear ultrasonograph equipped with a 5 MHz probe, using the water immersion method.

Classified patterns of a bottom area and intra-phymatoid non-echoic area were added to 7 items of diagnostic criteria for ultrasonography of the mammary glands and the findings were graded by scores.

The scores for malignant tumors based on thecriteria of ultrasonographic diagnoses were clas-sified by the following 3 items.

(1) unperceivable boundary echoes

(2) uneven internal echoes

(3) weakened posterior echoes
