New MRI technique detects cancer via sugar

Researchers at Johns Hopkins University have developed an MRI technique that homes in on sugar molecules shed by cancerous cells, potentially offering a new way to differentiate malignant from benign lesions, according to a study published online March 27 in Nature Communications.

Gadolinium persists in brain years after MRI scans

Researchers from the Mayo Clinic can't quite explain the clinical significance, but the discovery of traces of gadolinium in four areas of the brain several years after administration of MRI contrast is enough evidence to warrant further investigation as to the reasons why.

Public reporting does not reduce MRI scans for low back pain

Healthcare regulators looking to reduce overutilization of medical imaging through public reporting of unnecessary procedures may want to find a bigger stick. An analysis in Texas of public reporting of MRI scans for low back pain -- an often unnecessary procedure -- found the initiative to have little effect on procedure growth.

Brain MRI spots effects of prenatal exposure to air pollutants

MRI has shown reduced white matter in the brains of children who were exposed to toxic air pollution while in utero. This reduction may have led to behavioral and cognitive problems in the first seven to nine years of their lives, according to an article published online March 25 in JAMA Psychiatry.

JAMA: Early imaging questionable for older adults with back pain

Older adults who have spine imaging within six weeks after an initial visit for care for lower back pain were no better off the following year than similar patients who did not undergo early imaging, according to a study published in the March 17 issue of the Journal of the American Medical Association.

Canadian group succeeds with cyclotron-produced Tc-99m

Researchers from Centre de Recherche of the Hospitalier Universitaire de Sherbrooke, working in conjunction with the University of Alberta and Advanced Cyclotron Systems, have achieved a major advance by affirming that use of cyclotron-produced technetium-99m (Tc-99m) results in image quality equivalent to that of Tc-99m manufactured in a nuclear reactor.

SPECT/CT predicts foot amputations in diabetics

Technetium-99m white blood cell SPECT/CT imaging may be useful for identifying diabetic patients at risk of amputations due to foot infections.

April 24, 2024

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.
