Web15 de ago. de 2024 · The calculated mean ADC value of the grade I tumors was 0.93 × 10 −3 mm 2 /s [95%CI 0.84; 1.03] and the mean value of the high grade tumors was 0.77 × … WebCombining these factors yielded the best diagnostic performance, with the area under the ROC curve of 0.838, 72.9% sensitivity, 79.1% specificity, 65.2% positive predictive value, and 84.5% negative predictive value. Conclusion: With the mean > 1.08× 10 – 3 s/mm 2 and CV < 0.249, the ADC improved the diagnostic performance of LNM in T3 stage ...

WebObjectives: To evaluate the influence of the choice of b values on the diagnostic value of the apparent diffusion coefficient (ADC) for detection and grading of prostate cancer (PCa). Methods: Forty-one patients with biopsy-proven PCa underwent endorectal 3-T MRI before prostatectomy. Different combinations of b values (0-800 s/mm(2)) were used to … Web1 de jun. de 2014 · Results. DWI with measurement of ADC values helped in the differentiation of benign and malignant bone tumors, as malignant bone tumors have mean ADC values less than (1.31 × 10 −3) mm 2 /s; while benign bone tumors have mean ADC values 1.43 × 10 −3 mm 2 /s. Also, mean ADC values helped in differentiating … Web29 de out. de 2014 · They can be converted to percentages merely by dividing the raw value given by the ADC by the maximum possible value given the resolution of the converter. For example if your 8-bit ADC returns 100, you can say that it is (100/255) * 100 = 39.21% and can be seen as more of an "intensity" or "signal strength" in that case; however it really … date only showing month in pivot table
