LnQ helps alleviate staffing problems with radiology by tapping into the hidden capacity that already exists. Whether used internally within a group, across a number of friendly groups, or as an open market solution, LnQ offers a more user friendly, cost effective, and less burdensome solution than most organization's current processes. We have created a network linking radiologists who have extra capacity to the larger medical market of radiology groups, hospitals and imaging centers wanting extra help. We have eliminated the middle man driving up price, adding complexity, and decreasing individual radiologist reimbursement.
