How many CT scans can I have

There is no recommended limit on how many computed tomography (CT) scans you can have. CT scans provide critical information. When a severely ill patient has undergone several CT exams, the exams were important for diagnosis and treatment. Medical follow-up care is seldom required for radiation exposure from diagnostic examinations. Effects from radiation are too…

CTCoronavirus

Patients who test positive for pneumonia associated with the coronavirus largely share several findings visible on CT scans. Knowing what symptoms will likely appear on these images can help providers recognize which individuals will need targeted treatment. Together, radiology researchers from the Shanghai Public Health Clinical Center and the University of Michigan at Ann Arbor…

InSight Imaging announced the recent installation of a Philips Vereos PET/CT (positron emission tomography/computed tomography) system at their Honolulu location, the world’s first full digital PET/CT scan. This machine is only the 25th install in the U.S. and 67th worldwide This tool can help local physicians better make evaluations to determine the best course of…

CT scans reveal the dangers of vaping

New research published in the New England Journal of Medicine has linked e-cigarette use to a cluster of respiratory illness cases identified on CT scans. The results add to the growing concern that vaping may cause lung damage, an idea that manufacturers of vaping products have downplayed. The team, led by Jennifer Layden, PhD, chief medical officer of the Illinois Department…

PET scans measuring glucose more effective

A new study has found that PET scans measuring glucose may be a better indicator of the progression of Alzheimer’s disease than amyloid PET scans. As clinical trials targeting beta-amyloid plaques, toxic proteins that form in an Alzheimer’s patient’s brain, continue to fail, some researchers have started focusing their efforts on drugs that could clear…

CT Screeing for Lung Cancer

Often, patients with lung cancer are diagnosed in much later stages, but now 2 large randomized clinical trials have shown that low-dose computed tomography (CT) scans can help catch the cancer earlier on, according to Taofeek Owonikoko, MD, PhD, MSCR. “The National Lung Screening Trial (NLST) established the basis for screening for patients 55 years…

head ct scans in young adults

Head CT examinations do not put younger patients at a high risk of developing cataracts, according to new research published in Clinical Radiology. The lens is not always included in such scans, the authors noted, and even when it is, the associated radiation doses “appear insufficient to induce cataracts.” The study explored data from more than 410,000 children…

history behind the MRI

Computed Tomography (CT) imaging is also known as “CAT scanning” (Computed Axial Tomography). Tomography is from the Greek word “tomos” meaning “slice” or “section” and “graphia” meaning “describing”. CT was invented in 1972 by British engineer Godfrey Hounsfield of EMI Laboratories, England and by South Africa-born physicist Allan Cormack of Tufts University, Massachusetts. Hounsfield and Cormack were later awarded…

how long does an ct take

The time required will depend upon the type of scan. If oral contrast is required, about 45 to 60 minutes is needed for the contrast to move through your digestive tract. Actual scan times vary from a few seconds to several minutes. If no oral contrast is required, the examination will take about 15 to…

CT radiology report

Radiologists create radiology reports the way a carpenter creates a chair; it’s the final product, the end result of all of their labor, training, and expertise. That’s a simplification, but the general comparison holds. When you go in for a scan (whether it’s a CT scan, MRI, an X-ray, computed tomography, or any other imaging…
