| Imaging features | NCMRL(n = 43) | 99TCm-DX lymphoscintigraphy(n = 43) | Kappa value | P value |

| Obstruction of the thoracic duct outlet at the left jugular venous angle | 29(67.4) | 29(67.4) | 1.000 | 1.000 |
| Right jugular venous angle drainage of the thoracic duct and obstruction of the outlet | 1(2.3) | 1(2.3) | 1.000 | 1.000 |
| Bilateral jugular venous angle drainage of the thoracic duct and obstruction of the outlet | 1(2.3) | 1(2.3) | 1.000 | 1.000 |
| Tortuosity and dilation of the thoracic segment of thoracic duct | 2(4.7) | 3(7.0) | 0.788 | 1.000 |
| Abnormal visualisation of the subclavian trunk | 8(18.6) | 2(4.7) | 0.352 | 0.031 |
| Abnormal visualisation of the bronchial mediastinal trunk | 3(7.0) | 1(2.3) | 0.482 | 0.500 |
