Preliminary Study on the Qualitative Diagnosis of Renal Tumours B-mode Ultrasonography-Analysis on 118 Cases / 中华超声影像学杂志

ABSTRACT

Preoperative qualitative diagnoses of 118 eases of renal tumour.made by B-mode ultrasound were analyzed.The final diagnoses were proven operatively and pathologically.The resultsshowed that by B-mode altrasound the detective rate was 92.2%,a correct qualitative diagnosis rate 49.1%,incorrect rate 18.1%and false positive rate 1.7%.Qualitatively unidentified turnouts accounted for 32.8%of all the cases.It is assumed that B-mode ultrasound can be used to make correct qualitative diagnosis only on certain tumours with typical image features.It is difficult for it to distinguish some tumours which have complicated displays.The accuracy of preoperative qualitative diagnosis could be raised by combining B-mode uhradound with other imaging technologicol examinations.
