The Preliminary Investigation Of Ultrasound Contrast On Single Solid Thyroid Nodules

Purpose:Analyzes each pathology type thyroid gland single shot solid tubercle supersonic radiography the acoustic image characteristic, the appraisal supersonic radiography to good, the malignant thyroid gland tubercle diagnosis value.Method:One:Uses conventional two Uygur first supersonic and the colored Doppler supersonic observation thyroid gland and the tubercle acoustic image chart, the choice integrates the tubercle the best section, carries on the supersonic radiography inspection, real-time observation tubercle irrigation process and echo strength change. Two:After the radiography had ended, carries on the playbacking analysis to the storage phantom, analyzes after the surgery pathology confirmation 45 example thyroid gland single shot tubercle (malignant 30 examples, benign 15 examples) the supersonic radiography image characteristic. Compared with the tubercle interior and in the tubercle neighboring thyroid gland essence the contrast medium arrival time (secl), reaches the peak time (sec2), peak value intensity (PI), reaches when the peak tubercle neighboring thyroid gland essence's foundation intensity (BI), strengthened degree ratioâ–³A(PI/BI), starts to abate the time (sec3) and so on parameter differences. Three:Carries on the appraisal from the following 3 aspectsâ‘ Strengthened degree ratioâ–³A(PI/BI),â‘¡The contrast medium passes in and out the tubercle speed acoustic image characteristic (to enter quickly, enters slowly, draws back quickly, draws back slowly),â‘¢Strengthened characteristic (whether the centripetalism does strengthen, whether to strengthen evenly, whether ring-like to strengthen, whether to strengthen completely, when strengthening the infection boundary is whether clear, when strengthening the infection shape is whether regular.)Result:1. when the thyroid gland good, the malignant tubercle's strengthened degree ratioâ–³A(PI/BI) difference has statistics significance (P4.34, to diagnoses the malignant tubercle to have the value, Andâ–³A>4.34 time, to diagnoses the malignant tubercle to have the value,â–³A<1.78 To diagnoses the benign tubercle to have the value.2. various types thyroid gland tubercle contrast medium passes in and out the speed acoustic image characteristic:(1) "enters quickly":The papilliform tumor is quite even with other two groups of benign tubercle has statistics significance (P<0.05) (2) "enters slowly" The thyroid gland adenoma and the papilliform tumor comparison have statistics significance(P<0.05) (3) "leaves quickly":The papilliform tumor, the follicle shape cancer is quite even with other two groups of benign tubercle has statistics significance (P<0.05) (4) "leaves slowly":Two groups of benign tubercle is quite even with two groups of malignant tubercle does not have statistics significance (P<0.05)3. thyroid gland malignant tubercle strengthened characteristic:Thyroid gland single shot good, malignant tubercle in whether to strengthen completely, when strengthening do the tubercle shape whether rule two aspect differences have statistics significance (P<0.05) When malignant tubercle enhancement many strengthens not completely, the shape is much anomalous. The difference has in the statistics significance two signs, strengthens not completely peculiarity high (90.56%), when strengthening the tubercle shape anomalous sensitivity is high (94.77%).Conclusion:Thyroid gland single shot solid tubercle's supersonic radiography enhancement pattern existence many differences, have the vital clinical significance, the supersonic radiography technology can be good for the thyroid gland, the malignant tubercle diagnosis provides the effective phantom study information and the quantitative analysis method.
