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.

Radiologist and artist Satre Stuelke, MD, MFA, acquires CT scans of toys, food, and electronics.

The term “low dose” for reporting CT scan radiation dose is too vague, say editors of the journal Radiology. Here one editor discusses the goal of abolishing the term.

CMS is allowing local contractors to determine coverage of new oncology PET tracers, but tracers for neurological or cardiac uses aren’t included in the change.

The FDA has approved Lymphoseek (technetium Tc 99m tilmanocept) Injection imaging agent that helps locate lymph nodes in patients with certain cancers.

CT scans of mummies show that plaque build-up and clogged arteries occurred among people 4,000 years ago, as well as today.

Reducing the CT colonography radiation dose from 120 kVp to 100 kVp resulted in a significant decrease in dose but minimal decrease in 3D image quality.

CT lung cancer screening could save up to 12,000 lives per year in the United States - and even more could be saved if the criteria were expanded.

CCTA is effective for determining heart attack risk in patients with suspected coronary artery disease - even if there are no treatable risk factors.

CT texture analysis of primary esophageal tumors may be a potential imaging biomarker, helping determine the effectiveness of chemotherapy.
