Diagnostic Imaging

 

Athletes suffering suspected tears of the anterior cruciate ligament (ACL) are often adequately assessed with clinical diagnostic tests performed in the clinician’s office. When these are inconclusive, diagnostic arthroscopy is the gold standard—and MRI is a generally low-value option due to its time and cost burdens.

Parents may start to reconsider treatment options when it comes to the effects of anesthesia on their children thanks to new findings from Boston Children's Hospital. 

Radiology researchers at Children’s National Health System in Washington, D.C., have shown that infrared thermal testing is better than the human touch at finding wear spots and other defects in protective lead aprons.

After getting imaged, outpatients expect to hear back on the results within one to three days. If the wait goes longer than that, they’re likely to feel worried—or perhaps perturbed—and call in for themselves within five days, according to researchers at the University of Michigan.

Routine follow up CT imaging in elderly patients who have experienced head trauma may need to be implemented into standardized treatment plans at a more cost-effective rate, according to a recent article by JACR.

Blood test able to detect lung cancer recurrence months before imaging

Results from a new prospective clinical trial showed that a blood test looking at specific biomarkers was able to detect lung cancer recurrence about six months before conventional imaging methods found recurrence.

Diagnostic imaging varies in evaluation of patients with appendicitis at children's hospitals

study published in the Academic Emergency Medicine (AEM) found variations across children’s hospitals in regards to diagnostic imaging when evaluating patients with appendicitis. These distinctions were due to the variations in hospital-level resources.

Noninvasive imaging has high value in predicting major adverse cardiac event

Researchers from John Hopkins have found that using a combination of noninvasive CT angiography and stress tests could help to predict which patients are at risk of suffering a heart attack or other adverse cardiovascular event.

Pediatric MR imagers switching to more stable gadolinium contrast agent

As word has gotten around that macrocyclic gadolinium-based contrast agents (GBCAs) are more stable than linear GBCAs, and thus less likely to deposit in the brain, use of the former type has increased. However, in pediatric settings, at least, much education still needs to be directed to rads and referrers, according to the authors of a study published online March 10 in Pediatric Radiology.

Imaging roles when diagnosing mesothelioma

Confirmation of a mesothelioma diagnosis can be difficult—and this alone is only a small portion of the treatment timeline. Physicians use x-rays, MRIs, CT scans and PET scans during the early stages of diagnosis when a patient notices symptoms.  

Medical students performing emergency ultrasound scans boost care quality

Calling on ultrasound-trained medical students to perform point-of-care scans in the emergency department can be a workable way to obtain accurate diagnoses and ensure appropriate patient management, according to a study published online March 3 in the Journal of Emergency Medicine.

Researchers use MRI to link CSF flow in infants to autism

A team of University of North Carolina School of Medicine researchers found many toddlers diagnosed with autism at 2 years old had a substantially more extra-axial cerebrospinal fluid (CSF) at 6 and 12 months of age, before diagnosis is possible.

Researchers call for kicking ‘iodine allergy’ out of medical imaging

Designating radiology patients with the imprecise diagnosis “iodine allergy” may be dangerous, as it could lead to unnecessarily unenhanced scans as well as uncertainty in clinical management and sometimes even useless preventative measures.

‘Driller’ rad residents beat their ‘scanner’ peers at identifying lung nodules

Radiology trainees do better at detecting lung nodules on CT when they’ve been taught to “drill” rather than “scan” the images, according to a study published Feb. 24 in Academic Radiology.

Retired ‘ruggers’ imaged with MR spectroscopy for post-concussion problems

Absent signs of cognitive decline or functional psychological falloff, retired contact-sport athletes can be helpfully but perhaps not definitively imaged for neurometabolite markers of concussion with MR spectroscopy, as the modality has performed with modest sensitivity in a preliminary study.
