CMS has agreed to cover three oncology FDG-PET scans, a revision from the proposed single-scan coverage, and one PET advocates lauded.

The institutions that adopted PET/MRI after its 2011 approval reflect on the changes in workflow and protocol, and the utility and future of the new technology. This is the first in a two-part series.

SPECT/MR debuted this week at the SNMMI annual meeting as a new preclinical hybrid molecular imaging system with promises of higher resolution and lower dose.

Children’s risk from radiation exposure from CT scans drops significantly when dose from the highest-dose exams is lowered and unnecessary exams eliminated.

Contrast media with CT significantly increased radiation dose, so number and timing of contrast-enhanced scans should be optimized when setting protocols.

Experts may consider new guidelines for virtual colonoscopy, or CT colonography, screening after study shows women can be screened later than men.

PET images show why education can help people cope with the effects of Alzheimer’s disease in its early stages.

Patients with acute diverticulitis diagnosed by contrast-enhanced CT may benefit from early colonoscopies for colon cancer screening.

Digital chest tomosynthesis used as a screening tool for lung cancer shows comparable rates of detection to low-dose CT.

Study confirms earlier findings that low-dose CT detects more lung cancer than chest X-rays and lowers mortality from lung cancer.

CT scans performed on children and adolescents may contribute to a slightly elevated risk cancer over the following 10 years.

Rapid CT programs may lead to faster diagnoses, but some say they may not be appropriate for all trauma patients and could unnecessarily increase radiation risk.

VIDEO: Reimbursement for CT colonography has been a complicated path, but radiologists shouldn’t wait to pursue local coverage and set up a screening program, said Perry Pickhardt, MD.

Use of 18F-FDG PET/CT may help detect advanced disease in patients with ulcerative colitis or Crohn’s disease.

Computed tomographic colonography in patients symptomatic of colorectal cancer resulted in a significantly higher rate of additional colonic investigation.

Computed tomographic colonography (CTC), or virtual colonoscopy, was more sensitive than barium enema in detecting colorectal cancer and large polyps.

Lumbar spine CT radiation doses were lowered by 41 percent and still delivered diagnostic quality images.

Abdominal CT scans that include the lumbar spine but that are performed for other purposes may help identify patients with osteoporosis.

Standard CT protocol for trauma patients is leading to overutilization of the exam.

What if you could combine your CT and MRI machines, obtaining simultaneous and in vivo images? You’re one step closer, thanks to researchers like Ge Wang, PhD.

Early use of FLT-PET/CT screening during treatment for head and neck cancer can indicate long-term patient outcomes.

Concerns over inappropriate use of CTC prompted CMS to halt reimbursement, but research shows that CTC is not being used inappropriately.

Hitachi Medical Systems America Inc. has received FDA 510(k) clearance for its Scenaria Advanced 128 CT system, the company announced.

Single photon emission computed tomography ventilation/perfusion imaging may show early changes to the lung caused by cigarette smoke exposure.

Doctors don’t always discuss the risks of CT scans with patients. One researcher explains why and the implications for radiologists.
