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
