Understanding CT flow artifacts is key to better disease diagnosis
Understanding the mechanics of flow artifacts on CT or CT angiography (CTA) and how these artifacts are created is key to better disease diagnosis, according to a review published April 25 in RadioGraphics.
In the review, a team led by Caroline Robb, MD, of Mallinckrodt Institute of Radiology, Washington University in St. Louis, MO, described flow artifacts and how they are different from several types of conditions.
"At first glance, flow artifacts may appear as a simple distractor to the discerning eye of a radiologist," Robb and colleagues noted. "However, there are many instances when identification of these artifact...

CT cerebral angiography ED headache diagnosis more effective
CT cerebral angiography makes emergency department (ED) diagnosis of headache more effective, researchers have found.
A team led by Dustin Mark, MD, of Kaiser Permanente Medical Center in Oakland, CA, reported that use of the technique was associated with “fewer lumbar punctures and higher detection of unruptured intracranial aneurysms, with no significant change in missed diagnoses of subarachnoid hemorrhage or bacterial meningitis.” The results were published April 19 in JAMA Network Open.
The investigators conducted a study that included data from 198,109 encounters at 21 emergency departments that involved the us...

CT-FFR reduces invasive procedures for coronary artery blockages
CT fractional flow reserve (CT-FFR) imaging identifies patients with coronary artery blockage or narrowing who could benefit from revascularization -- and helps reduce the unnecessary use of invasive procedures, researchers have found.
A team led by Mangun Kaur Randhawa, MD, of Massachusetts General Hospital in Boston reported that individuals with significant narrowing and/or blockages identified on coronary CT angiography (CTA) who underwent CT-FFR had lower rates of invasive coronary angiography and ensuing percutaneous coronary intervention than patients who were not referred for a CT-FFR. The research was published A...

Experts: Consider BMI when imaging patients with chest pain
A patient’s body mass index (BMI) has a significant effect on how much radiation exposure they receive from chest imaging in cases of suspected cardiac ischemia, according to a study published April 9 in the Journal of the American Heart Association.
Cardiologists at Saint Luke's Mid America Heart Institute in Kansas City, MO, found that as BMI increases, so too does radiation exposure, although PET offers the least variability, followed by SPECT, and then coronary CT angiography (CCTA). The finding is key to providing “patient-centered” care, the group wrote.
“These data may be helpful to generate more accurate ...

SCCT highlights annual meeting program
The Society of Cardiovascular Computed Tomography (SCCT) is highlighting the program for its upcoming annual meeting, to be held from July 18 to 21 in Washington, DC.
The society plans to offer attendees "practical tools to support the exponential rise in the global utilization of cardiovascular CT," it said. The meeting will feature a new program called India Presents, consisting of abstracts from authors from the Indian subcontinent, and joint sessions with the Society of Cardiovascular Angiography Interventions (SCAI) and the American Society of Echocardiography (ASE).
Tracks for personalized learning will include Gam...

Can cardiac PET/CT ‘revolutionize’ heart care?
PET/CT is poised to become a key tool for imaging the coronary arteries – a clinical imaging exam that can reveal early warning signs of fatal conditions when patients present with symptoms of chest pain, experts say.
The “hybrid” scan – which combines molecular PET and anatomical CT images – may have its highest potential in visualizing early signs of so-called “perfusion deficits” (regions of obstructed blood flow), said Marcelo Di Carli, MD, a professor of radiology and medicine at Harvard Medical School, in a recent interview with AuntMinnie.com.
“[PET/CT] helps us differentiate a patient who has ches...

CTPA rates increase among pregnant women
The use rate of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) has increased among pregnant women -- but outcomes from these studies are often negative, researchers have reported.
A team led by Sameer Goyal, MD, of Northwell Health, Manhasset, New York, discovered that the rate of CTPA exams for PE among pregnant patients increased by more than 70% over a 10-year time period without a simultaneous increase in positive findings -- results that underscore the importance of assessing the risk of radiation exposure in this group. The study findings were published March 18 in the Journal of the A...

Calcifications on mammo could identify women at risk of CVD
Detecting breast arterial calcifications on routine mammograms could identify women at a higher risk of future cardiovascular disease (CVD), a study published March 13 in Clinical Imaging found.
Researchers led by Shadi Azam, PhD, from Weill Cornell Medicine in New York found links between such calcifications and older age, diabetes, parity, younger age at first birth, and hypertension in women who underwent both screening mammography and cardiac CT angiography (CCTA).
“Additionally, we found that when neither breast arterial calcifications nor coronary arterial calcifications were present, the estimated 10-year risk o...

Groups aim to standardize nuclear medicine imaging of CV infections
Eleven medical associations have released guidance on the use of PET/CT and SPECT/CT for patients with cardiovascular (CV) infections.
The recommendations could improve patient care, as current clinical tools are often insufficient in complicated cases, noted lead author of the guidance Jamieson Bourque, MD, of the University of Virginia Health System in Charlottesville. The document was published jointly March 11 in the Journal of Nuclear Cardiology, Clinical Infectious Diseases, the Heart Rhythm Journal, and JACC: Cardiovascular Imaging.
