Effect of motion on the ADC quantification accuracy of whole-body DWIBS

Background and methods Diffusion-weighted whole-body imaging with background body signal subtraction was introduced as a qualitative approach to detecting metastases in the body. A liver-mimicking phantom with embedded tumours that could be moved to replicate respiratory motion was developed to asse...

Zusammenfassung:Background and methods Diffusion-weighted whole-body imaging with background body signal subtraction was introduced as a qualitative approach to detecting metastases in the body. A liver-mimicking phantom with embedded tumours that could be moved to replicate respiratory motion was developed to assess its ability to accurately quantify ADC values. Results Mean tumour ADC values were unaltered by the motion; however, a significant ( p
