Adrenal nodule MRI calculator helps distinguish between adenomas and malignant tumors based on quantitative signal measurements.
To calculate the results for each component parameter and the result for Adrenal Signal Intensity Index (ASII), Adrenal-to-spleen CSI Ratio, Adrenal-to-spleen (ASR), Adrenal-to-liver (ALR), Adrenal-to-muscle Ratio (AMR).
Use to calculate the results for each component parameter and the result for Adrenal Signal Intensity Index (ASII), Adrenal-to-spleen CSI Ratio, Adrenal-to-spleen (ASR), Adrenal-to-liver (ALR), Adrenal-to-muscle Ratio (AMR). Adrenal signal intensity index (ASII) = (Adrenal nodule SI in-phase - Adrenal nodule SI out-of-phase) /Adrenal nodule SI in-phase X 100 Adrenal-to-spleen CSI ratio = (Adrenal nodule SI out-phase / Spleen SI out-of-phase) / (Adrenal nodule SI in-phase / Spleen SI in-phase) Adrenal-to-spleen ratio (ASR) = (((Adrenal nodule SI out-phase / Spleen SI out-of-phase) / (Adrenal nodule SI in-phase / Spleen SI in-phase)) – 1) x 100 Adrenal-to-liver ratio (ALR) = (((Adrenal nodule SI out-phase / Liver out-of-phase) / (Adrenal nodule SI in-phase / Liver in-phase)) – 1) x 100 Adrenal-to-muscle ratio (AMR) = (((Adrenal nodule SI out-phase / Muscle out-of-phase) / (Adrenal nodule SI in-phase / Muscle in-phase)) – 1) x 100
