Diagnostic Imaging

 

Researchers from the Boston University School of Medicine have found evidence of CTE in young athletes’ brains without signs of concussion, indicating the condition is directly tied to head impacts—but not necessarily concussive hits.

By 2030, an estimated 65.7 million people are predicted to be affected by Alzheimer’s disease (AD), a 30 million person jump from today’s total. But, there’s increasing evidence that biomarkers coupled with the correct imaging technique may provide crucial insights into the disease.

Postoperative CT, most notably 3D CT scans, are the preferred imaging technique in evaluating intra-articular screw penetration of proximal humerus fractures, according to a study published in Academic Radiology.

Headaches are common in children, and many tools, often related to neuroimaging, exist to diagnose the situation, but there remains little standardized procedure in approaching individual cases and little clarity around the benefits and risks of pursuing imaging.

A recent retrospective study of brain and spinal MRI of patients suspected or known to have multiple sclerosis showed that the introduction of a structured reporting template produced reports with more adequate information for clinical decision making. The results were published in the American Journal of Roentgenology

Decision support nips needless back-pain imaging in the bud

Point-of-care clinical decision support (CDS) has showcased its ability to safely head off unnecessary imaging of patients presenting with low back pain—the poster-child condition of overutilization and defensive medicine—in the busy emergency department of an urban academic medical center.

Combo ultrasound scoring system deftly diagnoses, rules out appendicitis

Researchers from the surgery and radiology departments at Yale University have developed a clinical-ultrasound scoring system that may be both sensitive and specific enough to preclude the use of CT for patients with suspected appendicitis. 

Prostate patients willing to pay more for high-sensitivity biopsy guidance

As long as they’ve got money in a health savings account (HSA), men are willing to pay considerably more to choose prostate biopsy guided by MRI plus transrectal ultrasound over prostate biopsy guided by transrectal ultrasound alone, according to a study published online in Urology Practice.

Novel steerable needle better than the conventional kind in CT-guided biopsy

Using a lean flank steak embedded with simulated anatomic obstacles, researchers have demonstrated the superiority of a steerable needle over a straight one in percutaneous CT-guided needle biopsy, according to a study published online April 26 in the Journal of Computer Assisted Tomography.

AI identifies TB with high precision

After training two deep-learning models to identify tuberculosis, researchers at Thomas Jefferson University in Philadelphia have gotten their human-free method to nail the disease with 96 percent accuracy, according to a study published online in Radiology.

Trauma CT imaging at non-trauma centers often inadequate

Subpar quality in trauma CT images acquired in non-trauma care settings hampers accurate radiological interpretation, suggesting that other-than-imaging assessments are best until these patients are sent to trauma centers, according to a study published online April 18 in the Journal of Trauma and Acute Care Surgery.

Hand-held EEG device shows promise in diagnosing head injuries

In a new clinical trial, researchers found that imaging is not the only tool that can be used to diagnose head injury with accuracy. A hand-held electroencephalogram (EEG) device proved a viable method of diagnosing brain bleeding.

Back pain patients help refine research via crowdsourcing, registries

Online crowdsourcing and patient-registry recruitment both work as avenues for soliciting input from patients on what aspects of their malady they’d like to see studied—at least when the malady is low back pain. 

Man or machine? Robot proves effective in diagnosing sports concussions

While most sports concussions are diagnosed through an individual’s experience or an onsite MRI or CT scan, a new technique is offering a tool that is much more accessible for players.

Early childhood sleep problems show up on brain MRI by 7 years old

Echoing a University of Chicago study showing that children with sleep apnea are at risk for brain damage, researchers in the Netherlands have shown a link between childhood sleep disturbances and smaller gray matter volumes.
