Diagnostic Imaging

Ultrasound scans of the calcaneus—or the heel bone—were equal to results gathered from dual-energy x-ray absorptiometry (DXA) for assessing bone health, according to new research published online in the March issue of The Journal of the American Osteopathic Association.  

“Our results may help in planning medical injury surveillance systems for future large-scale sports events tailored for each specific sport and may potentially aid in developing preventive efforts before and during competition,” wrote the authors of a Feb. 21 study published in Academic Radiology.

CT angiography (CTA) and transcranial Doppler (TCD) fall short in detecting cerebral vasospasm (CVS) and predicting delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH), reported authors of a recent study published in the inaugural edition of Critical Care Explorations.

A novel PET/CT imaging agent—18F-GP1—produced a high-quality image and yielded a high detection rate for diagnosing acute venous thromboembolism (VTE), reported researchers of a study featured in the February issue of The Journal of Nuclear Medicine.

Stereotactic ablative body radiation therapy (SABR) nearly doubled the overall survival of patients with inoperable stage I lung cancer compared to standard radiotherapy, according to results of a multi-center phase III trial published in the Lancet Oncology.

The FDA has approved nerve stimulation for treatment of episodic and chronic cluster headaches and acute migraines. The findings, detailed in a study published online Feb. 13 in PLOS ONE, could help personalize treatment for PTSD, which according to the National Institute of Mental Health impacts roughly 3.6 percent of U.S. adults per year. 

Breast cancer screening centers may want to consider implementing digital breast tomosynthesis (DBT) and digital mammography (DM) into their practice, according to results of a recent Radiology study. Pairing both modalities significantly increased the sensitivity and specificity of detecting breast cancers.

The imaging technique has proven reliable in detecting neuron loss in people with neurodegenerative illnesses, but now can serve as a marker of dopamine function in those without neurodegenerative disorders. It also provides many advantages over conventional invasive methods or modalities requiring radiation exposure, such as PET.

“The diagnostic performance and efficiency of current MRI may yield overall value when it is used as a first-line modality in pediatric ED for acute abdominal pain,” wrote Raza Mushtaq, MD, of the University of Arizona College of Medicine, and colleagues, in a new study published in Radiology.

Aggressive treatment is not warranted in patients with pediatric rhabdomyosarcoma (RMS), a malignant soft tissue tumor in the muscle tissue of children, according to a multi-site analysis of CT scans published in the Journal of Clinical Oncology.

Roughly 5,500 NHS patients who had fractures repaired with metal plates will need their x-rays reviewed after a hospital mix-up lead some patients to receive faulty implants, according to a recent report from The Independent. 

When imaging pediatric patients, dual-energy head CT decreased radiation dosage, reduced artifacts and maintained a high-quality image compared to conventional head CT protocols, reported authors of a Feb. 7 study published in Clinical Imaging.
