Oral contrast not needed to spot kids' appendicitis on CT
January 18, 2018 -- Administering oral plus intravenous contrast to children who were in the emergency department undergoing CT exams for suspicion of acute appendicitis increased their wait time without providing any diagnostic benefit, according to a study published in Emergency Radiology.  Discuss
Better clinical histories improve CT interpretation, billing
January 16, 2018 -- How can emergency departments improve their interpretation and billing for head CT exams? A paper published in the January issue of the American Journal of Roentgenology explains that reminding physicians to include thorough clinical histories with their orders may do the trick.  Discuss
Should chest CT scans be reviewed for breast lesions?
January 12, 2018 -- What should be done with incidental breast lesions detected in women receiving chest CT exams? A new study recommends not only that these lesions be followed up, but also that a new reporting scale similar to BI-RADS be used to classify the findings, according to results published in Clinical Imaging.  Discuss
CCTA predicts heart events in stable chest pain patients
January 11, 2018 -- By detecting high-risk plaque, coronary CT angiography (CCTA) can predict major adverse cardiovascular events in patients with stable chest pain, according to a January 10 study in JAMA Cardiology. But the jury is still out on whether CCTA findings should be added to risk stratification tools such as Framingham scores.  Discuss
FDA guidance urges lower radiation dose for kids
January 10, 2018 -- The U.S. Food and Drug Administration (FDA) on January 9 issued a new guidance urging healthcare providers to use the lowest radiation dose possible when performing medical imaging exams on children.  Discuss
Do more CT scans lead to more kidney surgeries?
January 9, 2018 -- The higher the number of chest or abdominal CT exams in a hospital referral region, the greater the probability that patients will undergo a renal procedure, likely due to the incidental detection of renal masses, according to a study published online December 26 in JAMA Internal Medicine.  Discuss
Doctors who order fewer CTPA scans detect more PE
January 8, 2018 -- Turns out that less really is more. Canadian researchers are reporting that doctors who order fewer CT pulmonary angiography (CTPA) scans for pulmonary embolism (PE) actually have a higher rate of successfully detecting the condition, according to a letter published online January 8 in JAMA Internal Medicine.  Discuss
Cancer deaths continue to fall, but CT lung screening lags
January 4, 2018 -- In its annual report on cancer, the American Cancer Society reported that cancer mortality in the U.S. declined by 26% over the past 20 years. But gains in lung cancer survival are being slowed because so few individuals who are eligible for CT lung cancer screening actually undergo the scans.  Discuss
CT dose tracking highlights differences among kids in ER
January 3, 2018 -- Radiation dose tracking software revealed that children who had CT scans in the emergency room (ER) of separate hospitals in Finland received considerably different radiation doses for head and cervical spine CT exams, according to a study published in Emergency Radiology.  Discuss
Risk-based lung cancer screening tops USPSTF guidelines
January 2, 2018 -- Using individual risk-based criteria to determine eligibility for CT lung cancer screening may avert more deaths from cancer than using current U.S. Preventive Services Task Force (USPSTF) guidelines, according to research published online January 1 in the Annals of Internal Medicine.  Discuss
