Soccer ball heading more risky for women than men
Heading a soccer ball may not always be the safest play on the pitch. Diffusion-tensor MRI has revealed that female soccer players have more microstructural white-matter changes in brain tissue than their male counterparts, according to a study published online July 31 in Radiology.

Language issues don't greatly delay MRI scans
At least one radiology department is not letting language barriers get in the way of timely MRI scans. Researchers in Michigan found no significant difference in wait times between patients who spoke English and those who didn't, according to a study published online July 26 in the Journal of the American College of Radiology.

FLT-PET points toward survival for glioblastoma patients
PET scans with the radiotracer F-18 fluorothymidine (FLT) can help determine which glioblastoma patients have the best chance for longer survival, according to a study published online on July 21 in the European Journal of Nuclear Medicine and Molecular Imaging.

MRI matches CT for appendicitis -- and without radiation
When used to diagnose and confirm cases of acute appendicitis in the emergency department, MRI can provide the same efficacy as CT without the risk of radiation exposure for patients, according to a study published in the August issue of Radiology. The findings support the use of MRI first for some patients.

CSF may be gadolinium's route to the brain
A study published in the August issue of Radiology offers further evidence of a mechanism for gadolinium deposition in the brain after the administration of MRI contrast. Researchers detected gadolinium accumulation in cerebrospinal fluid (CSF) -- even in patients with an undamaged blood-brain barrier and normal renal function.

FDDNP-PET shows brain injury effects in military personnel
Researchers have found that changes in PET scans of military personnel with mild traumatic brain injury are similar to those seen in retired football players with suspected chronic traumatic encephalopathy, according to a study published online July 17 in the Journal of Alzheimer's Disease.

LUS reliable for care strategies in infants with RDS
By Amerigo Allegretto
Lung ultrasound (LUS) scoring is reliable for determining whether preterm newborns need surfactant for suspected respiratory distress syndrome (RDS).
February 20, 2025
1Each lung has been split into three parts. Each area has been given a score between 0 and 3. Score values are shown in Ultrasonograms to match 4 different patterns. During a longitudinal scan with a high-resolution linear probe, pictures of patterns were taken. The scores are as follows: 0 means A pattern, 1 means B pattern, 2 means severe B pattern, and 3 means extended consolidation.

PSMA-PET tracer performs well in clinical trial

(A) Representative maximum-intensity projection and selected PET/CT images (fused, PET and CT only) of patient with metastatic prostate cancer at 1 hour after injection. (B and C) Low uptake of Ga-68 PSMA-R2 in salivary and submandibular glands is also demonstrated. (D) Images show heterogeneous uptake of Ga-68 PSMA-R2 with varying degrees of intensity in multiple spine bone lesions (vertebral sclerotic lesion with intense PSMA-R2 expression at its periphery indicated with red arrow).

CT best for diagnosing suspected wooden foreign objects in the eye
By Kate Madden Yee
CT imaging is best for diagnosing suspected intraorbital wooden foreign bodies, although MR imaging does offer valuable supplementary information.
February 20, 2025
A 7-year-old boy, imaged 15 hours post-injury. Axial CT images with soft tissue windows (WW/WL=350/50) (a) reveal a rod-shaped foreign body (white arrow) situated along the course of the right inferior rectus muscle. The soft tissue window demonstrates that the foreign body exhibits attenuation similar to orbital emphysema. Axial CT images (WW/WL=1000/−200) at the same level (b) show that the attenuation of the foreign body (white arrow) is markedly different from that of the air in the sinuses.

(A, B) Unenhanced coronal, (C) axial, and (D, E) sagittal deep learning super-resolution threefold parallel imaging -- accelerated turbo spin-echo MRI scans were obtained at 3-tesla field strength. (A) Coronal T2-weighted fat-suppressed (FS) and (B) coronal proton density (PD)-weighted MRI scans show a nondisplaced superior labral tear (arrows). (C) Axial proton density-weighted fat-suppressed, (D) sagittal T2-weighted fat-suppressed, and (E) sagittal T1-weighted MRI scans show continuation into a nondisplaced anteroinferior labral tear (arrows). All seven readers correctly diagnosed the arthroscopy-validated findings. (F) An arthroscopic photograph shows the anteroinferior labral tear (arrow). Image and caption courtesy of the RSNA.
