We observed small-area variation in computed tomography scan use for inpatients in New York State, even after controlling for relevant patient and hospital characteristics. We used the 2007 Healthcare ...

Industrial CT scanning works by taking several hundred to several thousand 2D x-ray images covering 360 degrees. Once the scan is completed, the 2D x-ray images are reconstructed in 3D, making it ...

Objective: To determine the diagnostic value of physical examination (including neurologic exam) for positive computed tomography scan findings in children with closed head injury, Glasgow Coma Scale ...

A new CT (computed tomography) scan method can reduce radiation dose by splitting a full C-ray beam into thin and small beamlets. A team of researchers at the University College London (UCL) ...

Purpose: To prospectively study the capacity of positron emission tomography (PET) and computed tomography (CT) to determine response soon after radical radiotherapy or chemoradiotherapy and, thereby, ...

Computed tomography (CT) scanning, which creates detailed 3D images of bones, soft tissues, and organs, is better than standard X-rays for investigating complex injuries, cancers, and vascular issues.

µCT stands for micro-computed tomography – or X-Ray imaging in three dimensions. Similar to hospital CT scanners, these devices are suited for preclinical X-Ray imaging with resolution to the ...

Timely radiographic studies are essential to oncology care. At our institution, a safety net hospital in a large metropolitan area, baseline assessment determined that the overwhelming majority of ...

The Centers for Medicare and Medicaid Services has announced a national coverage determination that expands coverage for lung cancer screening with low dose computed tomography (LDCT). This final ...

In 2023, airports around the UK are planning to remove hand baggage limitations and reduce steps in the screening procedure to create a smoother and faster security procedure for passengers. They will ...
