What does in an SAG LTO ultrasound mean?

SAG LTO stands for Single Access Generator Lung Target Only. It is a type of ultrasound-guided lung biopsy.

In an SAG LTO ultrasound, a thin needle is inserted through the skin into the lung. The needle is guided by ultrasound imaging, which allows the doctor to see the needle and the surrounding tissue. The needle is then used to take a sample of tissue from the lung.

SAG LTO ultrasound is a minimally invasive procedure that is typically done on an outpatient basis. It is used to diagnose lung cancer and other lung conditions.
