Back to the present: VA updates MRI design guide, part I
Some things just don't age gracefully and MRI technology is one of them. The U.S. Veterans Affairs Office of Facilities has realized this and is updating its library of imaging design guides, including the one for MRI. Although the guides are intended for VA facilities, MRI architectural consultants Robert Junk and Tobias Gilk explain in this two-part series why the guides will be a resource you don't want to be without.

The million dollar question: How much should MRI suite construction cost?
How much does it cost to build an MRI suite? The answer depends on many factors that are unique to each facility. MR facility planning experts Robert Junk and Tobias Gilk outline some of the basic rules of thumb that can be used to evaluate project budgets. Keep in mind that one size does not fit all and that those unique factors will impact the total project costs, but this blueprint is a solid starting point.

SPECT/CT predicts foot amputations in diabetics

Examples in two patients. (Top) Abnormal leukocyte accumulation was observed in the right 1st to 5th toes, with the radioactive lesions extending to the bone, indicating osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). Two spherical VOIs were drawn on diabetic foot infections (DFIs) and the highest SUVmax was 4.2 (higher than the cutoff of 1.1) Despite intensive treatment, the infection progressed, leading to the patient undergoing right below knee amputation 43 days after SPECT/CT. (Bottom) Mild focal abnormal leukocyte accumulation was detected in the right 3rd and 4th toes. The lesions were in contact with the bone, which raised a suspicion of osteomyelitis (left panel, MIP image; right panel, axial SPECT/CT). A circular VOI was drawn on DFIs and the SUVmax was 1.0 (lower than the cutoff of 1.1). After 10 weeks of antibiotic treatment, the infection was successfully resolved, and the foot was preserved.
