Feasibility of T2 Mapping and Magnetic Transfer Ratio for Diagnosis of Intervertebral Disc Degeneration at the Cervicothoracic Junction: A Pilot Study

Table 2

Comparison of the T2 relaxation time values and the MTR values between female and male patients at different anatomical levels of the cervicothoracic junction.

Anatomical level	T2 relaxation time values (ms)		P value	MTR values (%)		P value
	Female	Male		Female	Male
C7-T1	54.69 ± 19.45	57.75 ± 18.82	0.52	19.01 ± 0.56	18.39 ± 6.83	0.72
T1-T2	56.37 ± 19.18	56.73 ± 19.06	0.99	18.98 ± 0.33	18.29 ± 6.47	0.64
T2-T3	57.84 ± 14.30	63.47 ± 15.00	0.12	16.19 ± 0.31	16.81 ± 5.48	0.28

MTR: magnetization transfer ratio; ms: millisecond. All P values were calculated by Student’s t-test.
