CHICAGO — In a medical first, CT imaging and 3D printing technology have been used to help plan the surgical separation of conjoined twins. 

CHICAGO—Carrying around the extra weight of obesity damages knee cartilage just as surely as it hurts one’s cardiovascular health. A new study confirms the suspicion that losing the weight can mean slowing the osteoarthritis.

CHICAGO—Even after all their symptoms subside, some concussed patients have significantly diminished blood flow to the brain. The arterial spin labeling (ASL) method of fMRI can pinpoint regions affected by the curtailment—and may better guide physicians on when to allow acutely brain-injured athletes to get back on the field. 

The new National Geographic Channel series “Breakthrough” includes a segment titled “Decoding the Brain” that spotlights the wonders of MRI.

Common sense assumptions backed by ACR guidelines deem one-kidney patients a higher risk for kidney injury from iodinated contrast media, but a study published ahead of print in Radiology suggests the heightened caution is unwarranted.

There’s been a growing awareness among the public about radiation doses in medical imaging. However, while general concern might be growing, true understanding is lacking. How should radiology respond?

The cost advantage of CT colonography over colonoscopy in Medicare patients varies widely under a number of clinical scenarios, but a new analysis has found that the savings are there in every one of them—and may range as high as 58 percent. 

Ultrasound has long been known to accelerate internal drug absorption. A preclinical trial has demonstrated the feasibility of leveraging this process to better treat inflammatory bowel disease and other GI disorders.

Babies born prematurely are at elevated risk of living with neurological, cognitive and attention-deficit problems later in life, but they’ve got something going for them too: Their brains are particularly “plastic” and so may be malleable for early intervention.

Modern medical imaging is being increasingly used to solve some ancient riddles. The latest archeological investigation made possible by current imaging technology? An analysis of victims from the eruption of Mount Vesuvius nearly 2,000 years ago.

Calling outer space a unique environment for the human brain is a massive understatement. Floating free, with no “up” or “down,” is an experience most people don’t get to truly experience. It can also do a number on how astronauts think, making physical and mental tasks tougher.

Tracking the eye movements of 42 radiologists viewing CT colonography videos, British researchers found the physicians quite capable of spotting even very small polyps—but not so good at paying them sufficient attention to recognize them as true polyps.
