Purpose To develop and validate a method for performing inter-station intensity standardization in multispectral whole-body MR data. Methods Different approaches for mapping the intensity of each acquired image stack into the reference intensity space were developed and validated. The registration strategies included: “direct” registration to the reference station (Strategy 1), “progressive” registration to the neighboring stations without (Strategy 2), and with (Strategy 3) using information from the overlap regions of the neighboring stations. For Strategy 3, two regularized modifications were proposed and validated. All methods were tested on two multispectral whole-body MR data sets: a multiple myeloma patients data set (48 subjects) and a whole-body MR angiography data set (33 subjects). Results For both data sets, all strategies showed significant improvement of intensity homogeneity with respect to vast majority of the validation measures (P < 0.005). Strategy 1 exhibited the best performance, closely followed by Strategy 2. Strategy 3 and its modifications were performing worse, in majority of the cases significantly (P < 0.05). Conclusions We propose several strategies for performing inter-station intensity standardization in multispectral whole-body MR data. All the strategies were successfully applied to two types of whole-body MR data, and the “direct” registration strategy was concluded to perform the best.
