Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.

The measure evaluates the proportion of scans that exceed certain thresholds for image noise or radiation dose across 18 categories.
Emphysema on baseline lung cancer CT a sign of future mortality risk
“Lung cancer screening shouldn’t just be looking for nodules. That’s a small part of what we see on the CT scan.”
FDA clears GE Revolution Vibe CT scanner aimed at rapidly growing CCTA market
“FDA clearance comes at the perfect time, with guidelines being adopted clinically for cardiac CT and with positive reimbursement driving procedure growth," says Jean-Luc Procaccini, CEO, molecular imaging and CT.

Automated CT scoring system accurately predicts prognosis in stroke patients

The study used non-contrast CT and CT perfusion imaging to analyze agreement between an automated reader and human radiologists with differing experience levels.

Short CT colonography reporting intervention improves radiologists' detection of cancer

Given the positive findings of the trial, most radiologists would likely support the move to require assessments and accreditation for CTC reporting, experts explained recently in Radiology.

CT-based radiomics features can help diagnose COPD earlier than ever before

Using radiomic features from chest CT images could be more beneficial than standard pulmonary function tests at diagnosis and severity staging of COPD, doctors suggested in Academic Radiology.

When MRI is not feasible, computed tomography of the spine could offer a quick solution for diagnosing acute versus chronic fractures.

Specific chest CT findings linked with increased mortality in COVID patients

Three abnormalities, including pleural effusion and nodular consolidation, were all independent predictors of 30-day in-hospital mortality.

COVID-19 less severe among fully vaccinated patients, CT imaging study confirms

Even partially vaccinated individuals had a significantly lower risk of requiring supplemental oxygen or being admitted to the ICU, researchers detailed Tuesday in Radiology.
