GE Discovery LS 4 Slice PET/CT gives you the following benefits:


The GE Discovery LS provides perfect registered and fused anatomical and functional images for optimal treatment planning and followup.

Using GE’s PET Advance NXi functionality, the Discovery assesses the body’s chemical or physiological changes that often precede anatomical changes visible in CT or MR.

The Advance NXi within the GE Discovery LS ensures the highest 2D and 3D sensitivity, full-field uniformity of resolution and high count rate capability.

A refurbished, used GE Discovery LS is an affordable and very reliable option to introduce PET/CT imaging and its superior clinical usage into your department or clinic.
