Chest X-ray showing bilateral chylothorax. The cisterna chyli can be found in a thoracic MRI, making it possible to confirm chylothorax. However, MRI is not the ideal method to scan the thorax, and so it is rarely used. Another diagnostic technique is conventional lymphangiography. It is rarely used since there are equally sensitive yet less ...
Sirolimus is often effective as first-line management for chylothorax. [65] If chylous leakage or accumulations persist despite treatment, imaging with heavy T2 weighted MRI, MRI lymphangiography or thoracic duct lymphangiography can be considered. Pleural fusion procedures can be considered in refractory cases. [citation needed]
In human anatomy, the thoracic duct (also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal) is the larger of the two lymph ducts of the lymphatic system (the other being the right lymphatic duct). [1]
Accumulations of fluid and chyle are named based on their contents and location: pulmonary edema (the presence of fluid and/or chyle in the lung), pleural effusions (fluid in the lung lining), pericardial effusions (fluid in the heart sack), chylothorax (chyle in the pleural cavity); and chylopericardium (chyle in the heart sack).

Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques.

CT scan of the chest showing bilateral lymphadenopathy in the mediastinum due to sarcoidosis. Bilateral hilar lymphadenopathy is a bilateral enlargement of the lymph nodes of pulmonary hila. It is a radiographic term for the enlargement of mediastinal lymph nodes and is most commonly identified by a chest x-ray.
Ultrasonography uses sound waves to create an image. It may show where fluid is located in the chest. It also can show some tumors. Although ultrasound may detect fluid around the lungs, also known as a pleural effusion, sound waves are scattered by air.
Hyperpolarized 129 Xe gas magnetic resonance imaging is a medical imaging technique used to visualize the anatomy and physiology of body regions that are difficult to image with standard proton MRI. In particular, the lung, which lacks substantial density of protons, is particularly useful to be visualized with 129 Xe gas MRI.
