The Idaho Supreme Court upheld a lower court's decision Tuesday ordering a Boise hospital to pay more than $52 million for violating a contract it had with an MRI company. The decision is the latest development in St. Alphonsus Regional Medical Center's lawsuit, involving one of the largest awards to come out of Idaho district courts. The hospital had appealed the multimillion-dollar verdict returned in 2011. MRI Associates, which operates MRI Center of Idaho and MRI Mobile, first partnered with St. Alphonsus in 1985 in an attempt to make magnetic resonance imaging and other diagnostic tests more accessible.
