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.

Technologist educators could do more to get students active in professional orgs

Students training to become radiologic technologists in the U.S. could and probably should join at least one professional society, organization or association at the state or national level in order to optimize their access to up-to-date learning resources and opportunities. However, many accredited rad-tech education programs either don’t mandate such participation or give it sufficient financial support.

Children’s ERs choosing ultrasound over CT for tummy pain; general ERs encouraged to follow suit

Pediatric patients with nontraumatic abdominal pain are less likely to receive CT scans—and more likely to be imaged with ultrasound instead—in pediatric emergency departments than their peers taken to general emergency departments (EDs).

Paramedic-performed lung ultrasound deemed presently unfeasible

Patients experiencing respiratory distress are not well served by lung ultrasound administered by paramedics and remotely interpreted by emergency physicians, although this could change if training techniques advance along with telemedicine and ultrasound technologies.

In academic settings, women radiologists have attained equal pay, prestige

There is no salary gap between male and female radiologists working at academic medical institutions in the U.S., according to an analysis by Harvard Medical School researchers published online Sept. 5 in the American Journal of Roentgenology.

Surgeon-performed ultrasound recommended for appendicitis imaging

Surgeon-performed ultrasound should be the first imaging technique used to diagnose patients with suspected appendicitis.

Ultrasound shows high diagnostic performance, interobserver agreement for pediatric appendicitis

Ultrasound is a powerful tool for helping radiologists diagnose pediatric appendicitis, and it doesn’t much matter whether the interpreters are trainees working the night shift or daytime attendings. However, the residents and fellows in the study behind the result didn’t do as well at ruling out the condition when it wasn’t present, prompting the study authors to recommend more intensive training to avoid false positives.

Researchers recommend better hearing protection for MRI patients

Despite being outfitted with substantial hearing protection, 26 young and healthy volunteers with no history of auditory problems or ototoxic drug use suffered a temporary yet troublesome shift in hearing threshold after undergoing brain MRI in a study conducted in China and published online Aug. 16 in Radiology.

MRI shows video games affect gray matter in hippocampus

Recent research using MRI has shown a frustrated parent’s threat that video games will “rot your brain” may be exaggerated, but the activity can change a player’s brain in fundamental ways.

Large study finds no elevated risk of meningioma after CT of the head

Head CT does not increase patients’ risk of developing meningiomas, the usually benign but often slowly symptomatic brain tumors that have been suspected of forming more often in individuals exposed to concentrated doses of ionizing radiation.

Young appendicitis-possible patients well imaged with MRI over CT—and sometimes over ultrasound too

MRI is as good as CT at confirming or ruling out acute appendicitis in children, teens and adolescents, and it doesn’t matter whether the reading radiologist is specialized in abdominal or pediatric practice.
