CT

Canadian researchers developed a tool to use with low-dose CT screening that accurately estimates the probability of lung nodule malignancies.

Researchers determined radiologic findings among humans with influenza A H7N9.

Patients who undergo head and neck CTs have higher risk of developing cataracts than those never exposed to the procedure.

Observing children with minor blunt head trauma longer can help avoid unnecessary CT scans.

Radiation given during CT as part of whole-body PET/CT exams can be safely reduced without comprising image quality.

Higher-quality scans means radiologists are detecting more incidental findings. But how and when should they be reported and recommended for follow-up?

Despite the availability of clinical guidelines for optimal spine care for back pain patients, many unnecessary diagnostic imaging tests are being performed.

18F-FDG PET/CT can better assess bone marrow involvement in patients with newly diagnosed diffuse large B-cell lymphoma than can standard bone biopsy.

Web-based quality control system results in significantly fewer common image quality errors radiographs, CTs and MRIs.

Asymptomatic people at high-risk for lung cancer should undergo annual screening with low-dose CT, says USPSTF.

Parents may be underestimate the small increased cancer risk associated with their child undergoing a CT scan.

Physicians used significantly lower radiation doses for cardiac CT angiography when weekly dose reports provided feedback on the tests performed.

Low-dose CT lung cancer screening was most beneficial in the 60 percent of people who had the highest likelihood of dying from the disease.

Chest radiographs and CT can identify unique features of the H7N9 virus which may assist in the proper initiation of treatment.

Too many CT scans are still performed on children complaining of headaches.

Many more pulmonary emboli are being detected since the introduction of CT angiography, but the death rate has not decreased.

CT angiogram monitoring of patients with cerebral aneurysms helps identify if and when the aneurysms grow, increasing the risk of rupture.

MRI may replace conditional CT for appendicitis detection in adults because of its similar accuracy rate.

Nuclear medicine and MR technologists recommend regulations around education, certification and staffing for the new hybrid technology.

PET images may help determine which patients with major depression will respond best to medication or to cognitive behavior therapy.

PET imaging aids researchers in search for anti-nicotine vaccine, but shows there is still a lot of work to do.

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.
