Regression analysis for ex-vivo MOLLI T1 Relaxation time measurements: MOLLI T1-Relaxation time (dependent variable) and protein content (independent variable). Linear regression established that for ex-vivo measurements, protein content was associated with MOLLI T1-relaxation time measurements (r = − 0.69) Effusions were defined as non-malignant/negative histology (green squares) if patients had no known malignancy and histology/cytology was negative; as malignant/negative histology (red star) if patients had known malignancy but histology/cytology was negative; as malignant/positive histology (yellow circle) if patients had known malignancy and histology/cytology was positive.
