Synopsis

Motivation: At present, there are no relevant reports about application of T1 Mapping, T2 Mapping and T2* Mapping on the diagnosis of focal lesions.

Goal(s): To study the application of T1 Mapping, T2 Mapping, T2* Mapping and DWI in differentiating benign and malignant tumors in liver.

Approach: T1 Mapping, T2 Mapping, T2* Mapping and DWI were scanned in patients with lesions in liver. Values were measured and compared in differentiating benign and malignant tumors.

Results: The average T1, T2, T2* and ADC values in malignant lesions were significantly lower than the corresponding values in benign lesions. AUC were 0.93, 0.94, 0.736 and 0.91.

Impact: This study shows that Mapping techniques of T1 and T2 represents attractive and promising new tools in differential diagnosis of liver benign and malignant tumors. T2* Mapping is not reliable.
