Performing computed tomography pulmonary angiography (CTPA) with a high-pitch photon counting detector (PCD) offers enhanced signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) at a reduced radiation dose in comparison to employing an energy-integrating detector (EID), according to new research.
Offering a combination of simplified and personalized scanning for patients at significantly lower lifecycle costs than other dual-source CT systems, the Somatom Pro.Pulse may be a viable option for smaller rural facilities and outpatient imaging centers.
For patients who had a complete metabolic response to radiation treatment for head and neck cancer, the authors of a recent study found that surveillance imaging with PET/CT, MRI or CT did not improve outcomes in comparison to expectant management.

Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
The Rapid SDH module on the RapidAI platform reportedly offers a sensitivity rate of 93 percent for detection of hemispheric subdural hematoma on non-contrast computed tomography (CT) scans.
Assessing 20-year follow-up data from a cohort for an international study of annual low-dose CT screening for lung cancer, researchers noted an 81 percent survival rate after an initial primary lung cancer diagnosis for over 1,200 patients with a median 43 pack-year smoking history.
The ability to consider and comment on prior imaging in the radiology report may help reduce extraneous addenda requests.

In a newly updated guidance, the American Cancer Society recommends the expansion of annual lung cancer screening with low-dose computed tomography (LDCT) for current or previous smokers 50 to 80 years of age who have a 20-pack-year or greater history of smoking.
Featuring 12 prior FDA clearances for chest X-ray and non-contrast head CT, the Annalise Triage platform may help streamline radiology workflows and prioritize timely diagnosis of urgent conditions.
In a recent video interview series, Dushyant Sahani, M.D., discussed the critical role of contrast media in diagnostic imaging, lessons learned from the contrast media shortage, key considerations with generic agents and currently unmet needs with contrast agents.
