X-ray reveals how pin placement aggravates nerves in pediatric fractures
Supracondylar humerus fractures occur quite frequently in children, and this traumatic break is usually treated with cross-pinning of the displacement after reduction. However, iatrogenic ulnar nerve injury is a potentially significant complication. Turkish researchers used two radiographic parameters to assess the connection between pin insertion and nerve damage.

Scintigraphy shows breast cancer response to hormone therapy sooner
Only a third of breast cancer patients who have endocrine therapy respond to treatment, and the current tests for patient selection are less than optimal. Some imaging techniques may not show results for several months post-treatment. Scintigraphy could be a better, noninvasive way to predict treatment response, according to European researchers.

MR arthrography proves superior to standard MR in labral tears
Orthopedic surgeons are growing more confident in their ability to address labral tears with arthroscopic surgery, but imaging guidance is required beforehand to improve diagnostic accuracy. MR arthrography would be the best bet for assessing these hip abnormalities, according to researchers from Duke University in Durham, NC.

US overcomes x-ray's limits in pediatric ankle fractures
Sprained ankles would seem to be part and parcel of childhood. But when a simple sprain balloons into a serious problem, clinicians may be hard-pressed to come to a definitive diagnosis. While a three-view x-ray may reveal nothing out of the ordinary, an ultrasound exam can be very helpful.

High resolution, fast acquisition give 3D MRA edge in abdomen
Three-dimensional contrast-enhanced MR angiography (CEMRA) at 3 tesla is "extremely promising" for evaluating abdominal vasculature, according to researchers from the University of California, Los Angeles. The advantages of 3D CEMRA at 3 tesla include improved spatial resolution and a higher signal-to-noise ratio (SNR).

X-ray planning improves hip replacement surgical outcomes
Preoperative planning of total hip arthroplasty forces the surgeon to think in three dimensions, which is more likely to mitigate possible complications, such as dislocation or malfunction of the prosthesis. A group of orthopedic surgeons have backed x-ray for step-by-step mapping of hip replacement surgery.

MRS helps predict if antidepressants will prevail in geriatric depression
Measuring cerebral metabolites with MR spectroscopy (MRS) could help mental health professionals tailor treatment regimens for elderly people with depression, according to Japanese researchers. They found that dysfunction in the frontal lobes is the most likely reason for cognitive impairment and possible depressive psychosis in an older population.

New theranostics PET tracer shows promise
By Will Morton
A new gallium-68 (Ga-68) PET/CT radiotracer appears superior over F-18 FDG for detecting bone metastases.
April 17, 2025
Images of a 69-year-old man diagnosed with prostate cancer who had a history of endocrine therapy for two years. (a) The maximum intensity projection (MIP) image of F-18 FDG showed moderate radiotracer uptake in a thoracic vertebra. (e) The MIP image of Ga-68 DOTA-IBA demonstrated more lesions in the cervical vertebra and pelvis. (b) An osteoblastic lesion in the C3 vertebra right attachment (curved arrows) was negative on F-18 FDG (SUVmax = 2.0) and positive on Ga-68 DOTA-IBA (SUVmax = 8.7). (c) Another osteoblastic lesion in the T10 vertebra left side (arrowheads) was both positive on F-18 FDG (SUVmax = 5.2) and positive on Ga-68 DOTA-IBA (SUVmax = 35.0). (d) Osteoblastic lesions in bilateral ilium (dotted arrows and arrows) were negative on F-18 FDG (left: SUVmax = 1.4, right: SUVmax = 1.6) and positive on Ga-68 DOTA-IBA (left: SUVmax = 7.6, right: SUVmax = 8.7). Follow-up imaging three months later confirmed the presence of these bone metastases.

Ultrasound AC measures help detect liver steatosis
By Amerigo Allegretto
Attenuation coefficient (AC) measurements from ultrasound can help better detect hepatic steatosis and address interoperator agreement.
April 16, 2025
Ultrasound images depict a 56-year-old man with obesity (body mass index, 42) and steatosis (MRI-PDFF, 10.4%), who underwent ultrasound attenuation coefficient (AC) measurement due to participation in the present study. The unit displays color-coded confidence map (left) and AC map (on right) in side-by-side manner. The confidence map indicates quality of acquired AC signals and is set like traffic lights: green indicates good quality acquisition, yellow indicates warning, and red indicates low quality. Areas with low quality are left blank on the AC map. The image shows multiple circular ROIs placed at depths below the liver capsule of 2, 2.5, 3, and 4 cm. All ROIs are 3.5 cm in size. The confidence map threshold is set at 20%. AC measurements (in units of dB/cm/MHz) were extracted from all ROIs (excluding voxels without assigned color on the AC map) and decrease with greater ROI depth.
