Diagnostic Imaging

Using hyperpolarized xenon-129 (HXe) MR imaging, clinicians can better detect early lung disease in smokers before it progresses to chronic obstructive pulmonary disease (COPD), according to a Dec. 3 study published in Academic Radiology.

Shear-wave elastography (SWE) may help distinguish musculoskeletal soft-tissue lesions as benign or malignant in conjunction with conventional ultrasound, according to research published online Nov. 27 in Radiology.

New research suggests clinicians should increase follow-up times for evaluating ground-glass nodules (GGNs) found on CT from one to three years, according to a study published in Radiology.

“We need new, improved methods in which as few contrast agents as possible affect as much of the signal-emitting substance, which is typically water," said study author Leif Schröder, PhD, a researcher at the Leibniz Research Institute of Molecular Pharmacology (FMP) in Berlin.

Prenatal and postnatal ultrasonography alone—compared to combining the modality with MRI—was found to detect the most abnormal cases of Zika virus-related brain injury in infants and unborn fetuses, according to new research published online Nov. 26 in JAMA Pediatrics.

A recent study revealed middle-aged adults living with lung disease could be at greater risk of developing dementia or cognitive impairment as they age.

Treatment that delivers pulses of energy directly to nerves near the spine is a safe and effective procedure in patients with acute lower back pain, according to research presented Tuesday, Nov. 27, at RSNA 2018 in Chicago. The method may help patients who have not responded to conservative treatments.

A team of researchers used MRI brain scans to predict which patients would develop dementia within three years and were nearly 90 percent accurate, according to a small study presented at RSNA 2018 in Chicago.

“Selection of appropriate diagnostic imaging examinations is a critical step in the diagnostic pathway, however, trainees demonstrate widely variable knowledge of appropriate imaging, particularly pertaining to imaging pregnant patients,” Thaddeus D. Hollingsworth, MD, and colleagues wrote, in a recent study.

Three-dimensional (3D) MRI is similar to 2D for diagnosing meniscus knee injuries, but may be able to cut down on image acquisition time, reported authors of a Nov. 20 study published in Radiology.

A machine learning algorithm based on perfusion-weighted MRI accurately differentiated between benign and malignant tumors in the uterus, according to researchers at Tehran University of Medical Sciences (TUMS) in Iran.

Brightness of the shoulder’s deltoid muscle on ultrasound can identify patients with type 2 diabetes or pre-diabetes with almost 90 percent accuracy, according to a study being presented at the Radiological Society of North America (RSNA)’s 2018 Annual Meeting next week in Chicago.
