Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

CEUS works well for central-line check, less so for ruling out misplacement

Contrast-enhanced ultrasound (CEUS) imaging is safe, efficient and highly specific for confirming location and placement of central venous catheter tips in adult patients, according to a medical literature meta-analysis running in the December edition of the Journal of Ultrasound in Medicine.

POCUS excels in management of intra-abdominal hypertension

Point-of-care ultrasound has shown notable prowess as an adjuvant tool for aiding both diagnosis and treatment of intra-abdominal hypertension (IAH), a common complication in critically ill patients, according to a study published online Nov. 28 in Anaesthesiology Intensive Therapy.

RSNA 2017: Exercise alone won’t fend off osteoarthritis in knees

Exercise and improvement in eating habits, as two recommendations from a physician, could improve the overall health of most patients. Weight loss is associated with plenty of benefits. But MRI evidence presented at RSNA 2017 shows how an individual sheds extra pounds can impact the progression of knee osteoarthritis.

Defective lead aprons give themselves up to infrared light

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.

Awaiting imaging results, patients remain patient for up to 3 days

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.

New emergency rad-report system passes test

Radiologists and ED physicians at Brown University have developed a simple, five-category system for triaging imaged emergency patients based on their radiology reports, and the team’s test of the system has shown very good interobserver agreement.

MRI may predict outcomes for cardiac arrest patients with brain damage

Patients suffering brain damage after cardiac arrest may benefit from MRI, which could predict clinical outcomes by mapping brain activity.

Around the web

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

The FDA-approved technology developed by HeartFlow can predict a patient's long-term risk of target vessel failure as well as more invasive treatments performed inside a cath lab.
